AI capex game theory and constrained growth

In this episode of Excess Returns, Graeme Forster of Orbis joins us to discuss two major research papers: Six Courageous Questions for 2026 and Sunrise on Venus. We explore how long-running global trends may be reversing, what that means for U.S. dominance, the future of international and emerging markets, the risks and opportunities created by AI and massive CapEx spending, the dollar’s shifting role, and how investors should think about valuation, humility, and navigating a world where the economic “water” is changing. This conversation is packed with global macro insight, long-term investing lessons, and practical frameworks for building more resilient portfolios.

Topics Covered:
• Why long-term market “water” becomes invisible to investors
• Self-reinforcing global cycles and how China’s WTO entry reshaped the world
• Signs the 25-year U.S. outperformance cycle may be breaking
• How tariffs, political shifts, and corporate reforms change the global landscape
• Why international and emerging markets may now offer better expected returns
• Why U.S. large caps are not the entire story of American exceptionalism
• How to think about valuation, margins, and discounted cash flow models across markets
• The AI boom, bubbles, capital cycles, and asymmetric outcomes
• How AI CapEx constraints influence winners and losers
• The shifting role of the U.S. dollar and why market shocks may behave differently
• Maslow’s hierarchy, needs vs. wants, and the return of state-driven capital investment
• Deglobalization, reshoring, and the national-security lens for investing
• How to evaluate China and Taiwan inside emerging markets
• Why humility is an investor’s greatest edge
