S&P 500 moved to within 1% of its record high; futures slipped slightly in overnight trading following the session's gains.
Briefing
DeepSeek's release triggered a single-session wipeout of roughly $600bn in Nvidia market cap as investors questioned AI infrastructure capex assumptions. The subsequent recovery demonstrated that AI equity momentum can reverse and reassert within weeks, making current proximity to all-time highs fragile against any similar demand-signal disruption.
The Nasdaq-100 peaked and entered a prolonged drawdown as rate expectations shifted, with AI-adjacent and high-multiple growth names leading the decline. The current setup of record index levels driven by a narrow AI theme replicates the concentration dynamic that preceded that drawdown.
The Nasdaq Composite crossed 5,000 for the first time on AI-equivalent dot-com enthusiasm before a multi-year bear market. Burry's explicit framing of current AI positioning as analogous to prior speculative cycles he successfully shorted draws directly on this precedent.

Michael Burry's disclosed short book spanning MU, NVDA, AMAT, and CAT is directly stress-tested by this AI equity rebound. Each session of index momentum toward a new record raises the mark-to-market loss on his positions and increases the probability of a momentum-driven short squeeze in the names he is short.

Samsung's 1,800% Q2 profit beat that still sent the stock lower, combined with Asian markets retreating on US futures softness following the Dow 53,000 session, confirms that AI memory equities are priced for perfection and that positive earnings surprises no longer generate positive price responses in the Korean chip complex.

SpaceX's Nasdaq-100 inclusion takes effect during the same session window as the AI rebound, forcing passive QQQ inflows into an illiquid private-company proxy at elevated index levels and structurally raising the index's volatility profile at the worst possible entry point for cost-sensitive passive investors.
