    The Rundown 9/29/26: Quantum Reality Check, AI Risks, and Why Canada Is Missing Its Tech Opportunity

    Welcome back to another thought-provoking episode of Tank Talks! Matt Cohen is joined once again by John Ruffolo to break down the biggest stories shaping the future of technology, investing, and Canada’s economy. From the market reaction following Xanadu’s SPAC lockup expiration to the growing debate around whether Canadian pension funds are investing enough in homegrown innovation, this episode explores the opportunities and risks facing investors, founders, and policymakers. John also shares his concerns around AI privacy, Meta’s personal AI agents, the massive infrastructure demands behind AI adoption, and the future liability risks that come with increasingly powerful technology. Plus, Matt and John dive into Canada’s budget debate and question whether accounting strategies are masking the true scale of government spending. As AI reshapes industries, investors rethink risk, and governments navigate economic uncertainty, the decisions being made today will define the next decade. Xanadu’s Market Reality: AI Opportunity or Overhyped Valuation? (04:45) After Xanadu’s SPAC lockup expired, the quantum computing company’s stock faced significant selling pressure, dropping sharply as early investors and shareholders gained the ability to sell. Matt and John discuss founder Christian Weedbrook’s decision to sell a portion of his shares while maintaining a majority stake, and why John views the move as a strategic step rather than a negative signal. Why Aren’t Canadian Pension Funds Backing More Canadian Innovation? (09:29) Matt and John examine a recent investment by a Canadian pension fund into Harvey Legal, an AI legal technology company, and question why similar-sized investments are not flowing into more Canadian startups. John argues that Canadian pension funds have the capital and ability to support domestic venture and growth-stage companies, but many remain underweight in Canadian innovation. The conversation explores whether institutions are doing enough to support companies like Clio, Float Financial, and other Canadian technology businesses that are building globally competitive products. Meta AI, Personal Agents, and the Privacy Trade-Off (12:04) Meta’s new AI assistant has created excitement across the technology world, but John raises a major question: how much personal information should consumers be willing to hand over to AI platforms? The discussion explores the growing popularity of AI agents that connect to email, calendars, and personal data, and whether convenience is worth the potential privacy risks. While Matt highlights the power and usefulness of personal AI assistants, John remains cautious about giving technology companies access to sensitive personal information. The Hidden Cost of AI Growth: Compute, Capital, and Liability (14:10) As AI adoption accelerates, Matt and John discuss the enormous infrastructure requirements needed to support these systems. From computing power and capital expenditures to potential legal liabilities, the next phase of AI growth may depend on whether companies can continue scaling while managing the costs behind the scenes. The conversation also touches on Anthropic’s upcoming IPO concerns and the unanswered questions surrounding liability when AI systems make mistakes or operate unpredictably. Canada’s Budget Debate: Are The Numbers Telling The Full Story? (16:06) Matt and John close the episode by examining Canada’s deficit projections and the government’s approach to separating operating expenses from capital spending. John challenges the idea that certain spending categories should be treated differently when evaluating the country’s financial position, comparing it to how companies can manipulate profitability by changing accounting treatment. The discussion raises a broader question: are governments presenting a clearer picture of their finances, or are accounting methods making the numbers harder to understand?

    The Holy Grail of Energy: Why Fusion is Finally Having Its Wright Brothers Moment | Henry Gould (Daedal Systems)

    In this episode of Tank Talks, host Matt Cohen sits down with Henry Gould, founder of Daedal Systems, to explore his journey from a childhood fascination with physics to building the measurement infrastructure for the entire fusion energy industry. Henry shares his path from Queen’s Engineering Physics to the plasma diagnostics team at General Fusion, where he worked on the PI3 project and saw a structural problem: every fusion company was building the same diagnostics in-house, underinvesting in them because they weren’t core IP. They break down why fusion is fundamentally different from fission, the “triple product” that defines every reactor’s performance, and the 2022 breakthrough at the National Ignition Facility that served as the industry’s Wright Brothers moment. Henry explains why the biggest bottleneck to commercialization isn’t the physics, but the lack of standardized, trusted measurement systems to validate milestones for investors. He opens up about the “apparent conflict of interest” of being paid by customers while serving as an industry validator, why tritium is worth $30,000 per gram, and why Ontario’s CANDU reactors give Canada a strategic advantage in the global fusion race. Whether you’re deep in the fusion space, investing in frontier tech, or just curious about the Holy Grail of energy, this conversation offers a rare look inside the supply chain that will make or break the fusion industry. The Holy Grail of Energy: Why Fusion Is So Hard (02:35) * Why fusion is called the Holy Grail: abundant fuel from seawater and lithium, no long-lived radioactive waste, dispatchable power * The challenge: overcoming electrostatic repulsion to fuse positively charged nuclei at 100 million degrees Celsius * The two main approaches: magnetic confinement and laser inertial fusion, and the 2022 scientific breakeven milestone * The caveat: scientific breakeven only measures energy out of the plasma, not the total energy input to power the lasers Inside General Fusion: Plasma Diagnostics and the PI3 Project (04:52) * Joining General Fusion as an intern, then full-time on the plasma diagnostics team * The “first wall problem” and how General Fusion’s liquid metal wall approach solves it * What PI3 (Plasma Injector 3) is and why it’s essential to the reactor architecture * The challenge of measuring a superheated gas at 10 million degrees: you can’t just stick a thermometer in * The triple product: density, temperature, and confinement time as the universal benchmark for fusion performance Why Now? The Forces Converging on Fusion (10:02) * AI power demand making abundant energy essential * Geopolitical risk and the push for sovereign energy infrastructure * 40% year-over-year growth in fusion investment and 10% growth in the number of companies * Why investors are waking up to both the science risk and the massive payoffs The Founding of Daedal Systems: Standardizing the Missing Layer (13:00) * Seeing the structural problem: every fusion company needs the same diagnostics, but builds them in-house * Why diagnostics are underinvested relative to core IP * The vision: a platform of standardized diagnostic hardware and a generalized data analysis layer * Being architecture-agnostic: serving tokamaks, stellarators, mirror machines, and inertial approaches Measurement as a Service: Validation, Trust, and the Investor Milestone Path (17:05) * The fourfold value proposition: higher quality measurements, faster, focused on core IP, and validation * The codified development path * Why peer-reviewed papers take 18 months, and arXiv posts lack validation * The “apparent conflict of interest” of being paid by customers while serving as an industry validator * Why trust is the entire business: “Any distrustful act is going to kill the company for the long term” Ontario’s Strategic Advantage: Tritium, Talent, and the CANDU Legacy (20:28) * Why Henry moved back from Vancouver to build Daedal Systems in Toronto * The CANDU heavy water reactors and their byproduct: tritium, essential fuel for fusion * Tritium economics: $30,000 per gram, and 55 kilograms needed to start a reactor ($1.5–2 billion) * Canada’s vast majority of the world’s civilian tritium supply * The Center for Fusion Energy in Ontario and Daedal as the first private company on board Competing with Incumbents: Why Private Industry Needs Something Different (23:08) * General Atomics as the leader in plasma diagnostics for large public devices like ITER * Why private fusion companies need a measurement partner with a business model that works for them * The motivation for talent: working on infrastructure that benefits the entire industry, not just one device Beyond R&D: Adjacent Markets and the Long-Term Vision (26:38) * Starting with R&D-phase diagnostics for comprehensive understanding * Expanding to SMRs for neutron detection and other plasma industrial processes like semiconductors * The long-term vision: operating infrastructure for the fusion power industry * Why Daedal provides value today, not waiting for a mature fusion industry SMRs vs. Fusion: Clearing Up the Confusion (27:31) * SMRs as advanced nuclear fission: smaller, mass-manufacturable, competitive levelized cost of energy * Henry’s hot take: “I’ll wait to see what the energy price is” * The waste problem: long-lived radioactive waste vs. fusion’s much shorter-lived byproducts * Why fusion isn’t waste-free: tritium has a 12-year half-life, and neutron bombardment activates steel, but it’s fundamentally different from fission The Road Ahead: Becoming the Standard for Every Fusion Device (29:38) * The plan: become the measurement system provider for every next fusion device built * Accelerating the build-test-learn loop and commercialization * Building in downtown Toronto, at the heart of Canada’s nuclear ecosystem About Henry Gould Henry Gould is the founder of Daedal Systems, a company building the measurement infrastructure for the fusion energy industry. Previously, he worked at General Fusion on the plasma diagnostics team, serving as an engineer, physics lead, and technical project manager on the PI3 project. He holds a degree in Engineering Physics from Queen’s University and grew up in Toronto.

    Selling Without a Sales Team: How Railway Scaled GTM to $100M+ with Under 10 Reps | Rahul Parmar

    In this episode of Tank Talks, host Matt Cohen sits down with Rahul Parmar, Head of Go-to-Market at Railway and Venture Partner at Ripple Ventures, to unpack the real truths of building a sales engine in the modern AI era. Rahul shares his journey from being one of the first sales hires at Google Cloud in London to scaling Drata’s sales team from Series A to Series C, and now leading GTM at the developer-first cloud platform, Railway. He explains why the traditional sales hierarchy is becoming obsolete, how he built Drata’s engine by hiring in Toronto when it was a contrarian move, and why he believes Canadian reps are some of the best in the world. They break down the “time chamber” theory of selling in Canada, why the US market is a “shooting fish in a barrel” for trained Canadian talent, and the fundamental problem with Canada’s ecosystem: a lack of capital and customers, not a lack of great founders. Rahul also shares his spicy take on the AI boom, explaining why the era of marking up token prices is over and why enterprises will soon distribute their AI workloads across multiple models. Whether you’re a founder trying to land your first enterprise deal, a sales leader building a team, or an engineer contemplating a move to the Bay Area, this conversation offers a rare look inside the new playbook for winning in GTM. From Google Cloud to Drata: The Early Days of a Sales Career (02:07) * Joining Google Cloud in London as the 5th or 6th seller, when revenue was under $100M * The “confidence in the root” that Google provides, and using that shield to be transparent with customers * Why the best sales advice is: “Tell them what you do, tell them what you don’t do, and then shut up” * Transitioning to Drata as the first sales leader, taking it from $50M in revenue The “Time Chamber” Theory: Why Canadian Sales Talent is Elite (13:18) * The Dragon Ball Z analogy: Selling in Canada is like training in a weighted vest * Why Canadian buyers are incredibly difficult, forcing reps to master the fundamentals * How Canadian reps “crush it” when unleashed on the US market, where the propensity to buy is higher * The story of Drata’s top AEs in every segment being based in Toronto The AI Era of Selling: Fewer Reps, More Revenue (15:41) * Why you can now scale to $1B in revenue with a team the size of a Series A startup * The shift from a siloed GTM model to a unified one where GTM leaders are involved in everything * Why the era of the “forecast aggregator” sales manager is over * The new imperative: You’re either building the system or you’re selling deals * How Railway builds its own internal software, like its own Zendesk, to own the customer experience Railway: The Developer Experience First Cloud (20:49) * What Railway is: The cloud where you point to a GitHub repo and it just launches * Why they run their own steel: The rate limits and poor fit of building a cloud on another cloud * The importance of owning the entire stack for a usage-based business * Why post-close support is a huge part of the revenue game at Railway The Canadian Ecosystem: Capital, Customers, and the Need for Network Effects (25:21) * Why it doesn’t matter where the investors come from, but where the capital and customers are * The “tragedy” of successful Canadian companies, like Wattpad and Turbo Puffer, having their exit proceeds and financing led by US firms * The two fundamental problems for Canadian startups: access to capital and access to early customers * The “35 in Toronto vs. 35 in SF” thought experiment: Why you can’t monetize your network in Canada * Why companies like Datadog and Snowflake would have died in the water if they started in Toronto AI, GTM, and the Future of Sales (35:41) * How Rahul uses AI at Railway to do lookalike mapping of customers based on usage patterns * Why he doesn’t believe in high-volume, AI-driven cold outreach * The one quality he looks for in great GTM people: Intelligence, defined as listening for what’s not being said and storytelling * How to call “b******t” on a sales hire in an interview: Ask for second-level details on a deal * His spicy take: The era of marking up token prices is over; enterprises will soon distribute workloads across a mix of frontier and open-source models The Road Ahead: Building from Anywhere, Winning Everywhere (39:38) * The plan for Canadian founders: Build your product here, sell it in the US * The value of doing a stint at a high-growth US company, like Ramp or Anthropic, to absorb the culture and build a network * Why the next generation of Canadian founders should not apologize for building here * The “Build, Follow, or Get Out of the Way” mentality for the Toronto tech ecosystem About Rahul Parmar Rahul Parmar is the Head of Go-to-Market at Railway, a developer experience first cloud platform, and a Venture Partner at Ripple Ventures. Previously, he was the first sales leader at Drata, where he scaled the sales team from Series A to Series C. He was also one of the first sales hires for Google Cloud in London. He holds a degree from business school and built Canada’s largest coding bootcamp, Lighthouse Labs, before his career in high-growth SaaS.

    How Biossil is Rescuing Billion-Dollar Drugs Big Pharma Abandoned | Anthony Mouchantaf

    In this episode of Tank Talks, host Matt Cohen sits down with Anthony Mouchantaf, co-founder and CEO of Biossil, a biotech company on a mission to resurrect orphaned drugs using AI and a hedge fund–inspired operating model. Anthony takes us through his unconventional journey: from a law school student obsessed with Alexander Hamilton, to founding his first startup, Rthm (acquired), to investing at OMERS and RBC, and finally returning to the founder seat with Biossil. They dive into the mindset shift required to leave a stable legal career for the uncertainty of startups, why Anthony views entrepreneurship as a “drug,” and how his time as an LP shaped his view of what separates great VCs from mediocre ones. Anthony opens up about the early days of Biossil, the “too cute” capital-efficient strategy, and how a serendipitous dinner intro to Founders Fund changed everything. He also breaks down the real-world mechanics of acquiring off-the-shelf drugs, the brutal reality of biotech timelines, and why regulatory reform is the hidden bottleneck to AI-driven medicine. From the partnership with OpenAI to the company’s operating philosophy (hedging beta, maximizing catalyst density, and isolating alpha), Anthony offers a blueprint for building a resilient, mission-driven biotech for the AI era. Whether you’re a founder, investor, or just someone curious about the intersection of AI and life sciences, this episode is packed with hard-earned wisdom on risk, identity, and the art of controlling what you can control. From Law School to Startup Life (02:24) * Growing up in Toronto as the child of immigrant parents, chasing constitutional law * The Alexander Hamilton obsession that started in high school * Teaching a course at U of T law without ever practicing * How a late-night conversation at Massey College with co-founder Alex led to Rthm What Founding Rthm Taught Him About Himself (06:14) * Getting comfortable with structural uncertainty as almost “a drug” * Why you can take the individual out of the startup, but never the startup out of the individual * The itch that never fully goes away after founding something From Founder to Investor: OMERS and RBCX (07:11) * What separates great investors from destructive ones * “Extremely hard to kill”: what he saw early in Matt and Ripple Ventures * Why most VCs cluster around mediocrity, and what the outliers do differently * The poker-chip analogy: how capital position shapes VC risk appetite * Why good LPs need to “thumb the scale” for good VCs, just as good VCs do for founders The Idea Behind Biossil (15:05) * Reuniting with Alex, an MD-PhD, after years on separate paths * The core problem: drug development should be recursive, but biotechs can’t afford to make it so * Why promising drugs get stranded in “regulatory limbo” when the data is equivocal, not failed * The insight: using technology to systematize what was historically a relationship-driven, human-scale rescue effort Biossil 1.0 vs. the Bigger Vision (20:43) * Launching in 2023 on a lean seed round with no capital to acquire drugs outright * Getting “too cute” trying to solve the problem at a fraction of the necessary cost * Why most VCs evaluate founders cross-sectionally instead of longitudinally Hunting for Orphaned Drugs (26:03) * Why data is a cost of admission in biotech, not a moat like in tech * How Biossil structures deals to share economics with original rights holders * Why inbound interest rarely meets their bar Running Biossil Like an Operating Hedge Fund (30:50) * Isolating alpha, or execution, from beta, or market and biotech cycle risk * Why traditional biotech investing is “binary risk you can’t underwrite” without a portfolio * Building resilience through catalyst density instead of just runway * The “epsilon” factor: surviving long enough for unexplained outcomes to work in your favor Building Lean with AI (34:12) * Running a hyper-efficient, eight-person core team * Why Biossil takes on regulatory and commercial risk, not manufacturing risk * The pipeline today: $70M raised, 11 drugs, 5 open clinical trials across the US, Canada, and Europe * What makes manufacturing the most underestimated cost in biotech The Next 5-10 Years for Biossil (49:47) * The long-term vision: an approved-drug pipeline, deeper trials, more disease areas * Bringing new mechanisms of action to market as a category-defining goal Advice to His Past Self (51:15) * Why he’s hesitant to just tell people to “go do entrepreneurship” * Motivation matters more than the identity of being a founder * The Steve Jobs commencement speech that reframed how he thinks about risk About Anthony Mouchantaf Anthony Mouchantaf is the co-founder and CEO of Biossil, a biotech company that uses AI to systematically identify, acquire, and advance orphaned drugs left behind by failed clinical trials. With a background in law (U of T), startup founding (Rthm, acquired), and venture investing (OMERS, RBC), Anthony brings a rare blend of legal, financial, and operational discipline to the high-stakes world of drug development. Biossil is backed by Founders Fund and OpenAI, and is on a mission to turn industrial-scale drug resurrection into a new category of biotech innovation.

    The Rundown 9/14/26: Canada-U.S. Trade Talks Collapse, Anthropic’s AI War, and Miro’s $16B Fall

    Matt Cohen and John Ruffolo break down the collapse of Canada-U.S. trade negotiations, the unanswered questions surrounding the failed deal, and whether Canada is protecting legacy industries at the expense of technology and long-term economic growth. They also examine Prime Minister Mark Carney’s ambitious pitch to bring international capital back to Canada, including billions of dollars in proposed energy, transportation, infrastructure, and technology projects. But can a polished deal book convince investors to fund projects that have struggled to attract capital for years? Finally, Matt and John unpack the political battle forming around Anthropic’s anticipated IPO, the growing influence of AI regulation campaigns, and Miro’s dramatic fall from a $17.5 billion valuation. As Canada searches for a way out of its trade crisis, global investors are being asked to reconsider the country’s economic potential. At the same time, AI companies are entering a political and regulatory battle that could determine who controls the industry’s future. If you are a founder, investor, policymaker, or anyone trying to understand where capital and technology are heading next, this episode is worth your time. – A big thanks to our sponsor, Moomoo Canada This is the kind of tooling that used to live on a Bloomberg terminal, but now it is on your phone, just a few taps away.

Open an account today at moomoo.ca Why Canada-U.S. Trade Talks Fell Apart (01:31) The latest Canada-U.S. trade negotiations appeared close to producing an agreement until everything suddenly unraveled. John argues that the biggest problem is not simply the failed deal, but the Canadian government’s refusal to clearly define what success was supposed to look like. With provinces reportedly objecting to parts of the proposed agreement and conflicting stories emerging from both sides, Canadians are left guessing about what happened. John asks the uncomfortable question: Is Canada protecting dairy and other legacy interests while sacrificing its technology economy? The Real Cost of Walking Away From the U.S. (07:43) Many Canadians support ending the negotiations, but that support begins to disappear when higher taxes, rising unemployment, and slower economic growth enter the conversation. John warns that Canada cannot reduce its dependence on its largest trading partner without experiencing real financial pain. That burden will not be shared equally. Older Canadians with homes, pensions, and U.S. investments may be able to absorb the disruption, while younger Canadians already struggling with housing and affordability have much more to lose. Carney’s Plan to Bring Investment Back to Canada (10:18) The Canada Investment Summit is presenting more than 160 opportunities across energy, critical minerals, transportation, manufacturing, digital technology, and infrastructure. The goal is to reintroduce Canada to international investors after a decade in which global capital largely looked elsewhere. John supports the strategy but tempers expectations. The summit may not produce immediate checks, but it could rebuild the relationships Canada needs to finance major projects and reverse its reputation as an undercapitalized market. Anthropic’s IPO Enters the AI Political War (16:15) A former Anthropic researcher’s warning about self-improving superintelligence quickly spread across the internet, creating fresh questions about AI safety and the company’s anticipated IPO. Matt examines whether the viral backlash emerged organically or was amplified by politically connected organizations pushing for tighter AI regulation. John believes there is no neutral position in the AI debate anymore. Competing groups are funding optimistic and catastrophic narratives, turning data centers, employment, regulation, and AI safety into deeply political issues. Despite the controversy, he does not expect the backlash to derail Anthropic’s IPO. Miro’s Collapse and the Continuing SaaSpocalypse (21:11) Miro was valued at $17.5 billion at the height of the software boom. Its reported acquisition by Bending Spoons at a fraction of that valuation shows how brutally the market has repriced venture-backed SaaS companies. Miro remains a substantial business with hundreds of millions in recurring revenue and a strong enterprise customer base. The problem was not the product; it was the inflated valuation and financing structure built around it. John expects more overfunded unicorns to face similar outcomes.

    How Rock Bottom Turned Chris Pronger Into an NHL Legend

    In this episode of Tank Talks, host Matt Cohen sits down with Chris Pronger, Hockey Hall of Famer, Norris and Hart Trophy winner, Stanley Cup champion, two-time Olympic gold medalist, and one of the NHL’s 100 greatest players. Chris takes us inside the mindset that transformed him from a booed 21-year-old in St. Louis into one of the most dominant defensemen of his generation. They break down what it really takes to bet on yourself, why delayed gratification is the secret to sustained excellence, and how Chris rebuilt his entire training protocol from the studs after already being nominated for a Norris Trophy. Chris opens up about the early-career failures that forced him to look in the mirror, the veterans who shaped him, from Brad McCrimmon to Wayne Gretzky and Al MacInnis, and the 4-pound muscle between his ears that changed everything. He also shares hard-won lessons on leadership, managing teammates with different personalities, the importance of culture in championship runs, and why the best leaders lead by example, not just by talking. From the 2007 Stanley Cup run with Anaheim to the scary commotio cordis incident in 1998 and the eye injury that ultimately ended his career, Chris delivers a raw, unfiltered look at the true cost of greatness. Whether you’re an athlete, a founder, a leader, or simply someone trying to earn your way forward, Chris offers practical wisdom on resilience, identity, and the art of controlling what you can control.

    The infrastructure behind the next wave of interactive AI | Keegan McCallum (uRun, ex-Luma AI)

    In this episode of Tank Talks, host Matt Cohen sits down with Keegan McCallum, co-founder and CEO of uRUN, an inference provider built for persistent, steerable, interactive AI experiences. Keegan’s path took him from jailbreaking iPods in Thunder Bay, Ontario, to building the infrastructure that powered Luma AI’s viral Dream Machine launch, scaling from 500 to 9,000 H100s in six hours to process over half a million videos. They break down why the industry is wrong to shoehorn interactive AI into old request-response systems and why the future belongs to persistent, stateful, real-time experiences. Keegan explains the technical differences between LLMs and video models, why infrastructure is the biggest bottleneck for the next wave of AI, and what it takes to recruit top engineering talent. He also shares hard-won lessons on selling to developers, the Canadian AI talent landscape, and his bold, contrary views on the AI supply chain. From avatars and steerable video to coding agents generating 1,000 tokens per second, this episode is packed with frontline insights. Whether you are a founder building in AI, an infrastructure engineer, or simply curious about where human-computer interaction is headed, Keegan delivers a clear-eyed look at the future of interactive AI. – A big thanks to our sponsor, Moomoo Canada This is the kind of tooling that used to live on a Bloomberg terminal, but now it is on your phone, just a few taps away.

    The Rundown 8/24/26: Canada’s Hidden Leverage in America’s AI Race

    Canada is back at the negotiating table with the U.S., looking for relief from tariffs on autos, steel, aluminum, forestry, and other goods. Matt Cohen and John Ruffolo break down the latest developments, including the possibility of a revived Keystone XL project and the concessions Canada may have to make to get a deal across the line. But John’s bigger concern is what Canada could give up in the process. He argues that digital services and technology are becoming the new economic battleground, and Canada risks protecting traditional industries while giving away ground in the sectors that could drive future growth. Matt and John also question why Canada is negotiating from a fragmented position while the U.S. approaches the talks as a unified front. The episode delves into Ontario’s new rules for AI data centers, the growing debate over who should pay for the massive infrastructure needed to power AI, and Anthropic’s unusual founder-control structure ahead of a potential IPO. Matt and John also look at Stripe’s decision to remain private while making a major AI acquisition, Clearco’s unexpected comeback after securing new financing, and why Canada may be falling behind the U.S. on blockchain despite having some of the strongest talent in the space. If you want a sharper read on where the U.S.-Canada trade, AI infrastructure, and digital sovereignty are heading next, this episode is a must-listen. – A big thanks to our sponsor, Moomoo Canada This is the kind of tooling that used to live on a Bloomberg terminal, but now it is on your phone, just a few taps away.

Open an account today at moomoo.ca Canada’s Trade Gamble (03:05) John warns Canada may trade digital sovereignty for short-term wins on oil and agriculture, calling it “solidifying the past and giving up the future.” He explains how U.S. statecraft has cleverly undermined Canada’s domestic tech industry through data and content restrictions. Ontario’s AI Data Center Crackdown (08:54) Ontario rolls out new rules forcing AI data centers to pay higher electricity rates and cover infrastructure costs. John says the move was inevitable and raises legitimate questions about whether AI’s benefits will be widely shared. Anthropic’s Super-Voting Share Plan (12:52) Anthropic plans super-voting shares and a trust to insulate its founders, who own only about 2% each, ahead of a potential $2 trillion IPO. John calls it bad governance but admits the public likely won’t care given the company’s explosive growth. Stripe Stays Private and Buys Big (17:24) Stripe acquires OpenRouter for $8 billion in stock while staying private, with revenues up 41% and free cash flow rising 43%. John asks why they’d ever go public if secondary markets provide liquidity and they can avoid quarterly scrutiny. Clearco’s Comeback (19:48) Clearco secures a $100 million Macquarie facility, cutting its cost of capital by 50% in a stunning turnaround. The chairman describes it as rebuilding an airplane mid-flight, and they’ve pulled it off. Is Canada Losing the Blockchain Race? (20:56) With U.S. crypto rules advancing and Canada stalled since the Stablecoin Act, John warns the real opportunity is in unified ledgers, not currencies. He notes Canada’s best blockchain talent is building for American companies, not Canadian ones.
