"AI has evolved to autonomous agents executing real work, fundamentally expanding demand beyond chatbots. The manager built a custom research system using coding agents, experiencing firsthand how previously uneconomical projects become viable."
Longriver Partners Fund returned 8.5% in Q2 2026, bringing year-to-date performance to flat and since-inception annualized returns to 14.5%. The manager provides an extensive analysis of AI's evolution from chatbots to autonomous coding agents, drawing on personal experience building a custom research system. This shift from token-based consumption to work-based demand represents a fundamental change in AI's economic value. However, the letter expresses growing concern about capital cycle risks as the AI infrastructure build-out accelerates. The manager describes an arms race where Big Tech companies are committing massive capital using debt and leases beyond operating cash flow, creating a prisoner's dilemma where the industry may collectively overinvest. Competition is intensifying across all layers of the stack as everyone tries to control customer relationships while making suppliers interchangeable. The portfolio's AI-exposed holdings (Amazon, KLA, Meta, Nvidia, TSMC) comprised 35% before reductions. The manager is raising cash and reducing AI exposure to maintain flexibility, preferring businesses whose competitive positions should remain valuable after current bottlenecks ease. The letter questions whether AI will generate adequate returns for all participants despite transforming business and society.
