Welcome to Markets Desk, here's what's moving the conversation today.
Leopold Aschenbrenner's AI-focused hedge fund Situational Awareness has become the talk of Wall Street after the Gen Z founder, who left OpenAI to launch the firm, was forced to sell most of its public stock portfolio to Citadel following significant losses in AI-related positions. It raises hard questions about whether concentrated bets on AI names can survive this kind of volatility.
Shifting to Amazon, CEO Andy Jassy made a compelling case on Thursday that winning the AI race isn't about having the best model. Customers want access to many models simultaneously, and Amazon is leaning into that multi-model architecture while building proprietary models to reduce internal costs and accelerate deployment. It's a strategic pivot that reframes the entire competitive landscape.
Meanwhile, over at Berkshire Hathaway, a quieter story is gaining traction. Under incoming chief Greg Abel, the legacy energy positions that Warren Buffett built — Chevron and Occidental Petroleum together representing over eight percent of the equity portfolio — are continuing to deliver. With oil holding firm, those bets are looking increasingly well-timed heading into the transition of leadership.
That's the tape. Markets Desk, signing off the floor.
