Kate Scott-Dawkins and Sam Weston continue their "Four Futures" series exploring potential scenarios for AI and advertising in 2035. This week, they dive into The Sovereign Stack—a future scenario characterized by concentrated control driven by public, civic, and government interests. They discuss how nation-states are asserting control over critical AI dependencies like compute, data, and security, how this fragments the global internet into regional intelligence ecosystems, and what this geopolitical shift means for global brands, agencies, advertising infrastructure, and media measurement. Key Topics Discussed Defining The Sovereign Stack: How governments maintain control over the intelligence supply chain (compute, data, digital identity, cybersecurity) without necessarily owning every AI model outright.Geopolitical Regionalization: How AI environments will reflect regional values and state priorities across the US, Europe, China, and the Global South.Cybersecurity as a Catalyst: How threats to critical physical and civic infrastructure (water systems, healthcare, utilities) accelerate state intervention and state-guaranteed AI defense.Capital and Infrastructure Demands: The massive physical investments required for data centers, power grids, and chip supply chains, alongside potential new tax policies on automated productivity.Open Source Models & State Sovereignty: Using open-weight models to reduce national dependence on foreign platforms and keep sensitive data local.Impact on Global Advertisers and Agencies: Navigating fragmented local jurisdictions, maintaining universal brand identity while localizing AI execution, and the evolving role of agencies as systems integrators and diplomatic partners.Backcasting Timeline (2026–2035): The five-stage progression from early public-private partnerships to nationalized champions, AI-native states, and international AI trade agreements.Strategic Actions for Marketers: Building a sovereign-ready commercial stack, managing state-affiliation brand risks, and tracking key policy signals.Chapters 00:00 - Introduction & Welcome 01:16 - What is The Sovereign Stack? 02:30 - Ownership vs. Control over AI Dependencies 04:41 - Living in 2035: Borders on the Intelligence Layer 05:31 - Geopolitical Divergence: US, Europe, China, and the Global South 08:08 - Current Signals of Government AI Intervention 13:31 - Cybersecurity as the Catalyst for State Involvement 17:06 - Physical Infrastructure: Compute, Silicon, and Chips 19:09 - The Positive Vision for Sovereign AI 21:42 - How Governments Currently Shape Advertising 25:53 - Impact on Global Brands and Marketing Strategy 28:51 - Media Ecosystems, Clean Rooms, and Measurement 30:02 - Backcasting Timeline: From 2026 to 2035 34:02 - Three Strategic Actions for Advertisers Today 37:16 - Media Recommendations and Closing Remarks
