This Substack newsletter announces The Leverage Launch, a one-night build event in San Francisco sponsored by Cursor, and covers several technology and AI developments: OpenAI’s new model (codename Astra) reportedly solved open mathematics problems using about $2,000 in API tokens; Ilya Sutskever’s Safe Superintelligence disclosed a partnership with Nvidia including a reported $5 billion investment; Nvidia’s investment strategy across AI labs and neoclouds (CoreWeave, Nebius, etc.) is highlighted; LinkedIn introduced a “Seems like AI slop” button and removed an AI post-enhancement feature amid findings that ~41% of long-form posts may be AI-generated. The newsletter also mentions cultural notes and consumer product endorsements.

Power rankings of big four hyperscalers post-earnings

Jim Cramer evaluates the four major hyperscalers after recent earnings calls, ranking Amazon first, Microsoft second, Alphabet third and Meta fourth. Amazon CEO Andy Jassy raised 2026 capex by $20 billion to $220 billion and said AWS has an AI run rate over $25 billion, with potential to become a $1 trillion annual revenue business over time; Amazon shares jumped 15.3% after the call. Alphabet raised its capex guide by $15 billion to $195–$205 billion but drew investor criticism for its earnings tone and posted its first negative free cash flow quarter since 2004. Microsoft showed strength via Copilot and Azure, including over 30 million paid Copilot seats. Cramer notes Meta lacks a clear plan to monetize its data-center spend, while SpaceX has begun renting compute to Anthropic and Google. The piece frames heavy AI-driven data-center spending as a competitive race that can be monetized if firms have cloud businesses to sell.

AI Hedge Fund Situational Awareness Forced Sale, Citadel Buys Portfolio

Leopold Aschenbrenner, a 24-year-old former OpenAI Superalignment team member, founded the AI-focused hedge fund Situational Awareness LP after stints at the FTX Future Fund and OpenAI. The fund grew rapidly—peaking near $45 billion—on concentrated bets in AI infrastructure and semiconductors, but suffered severe July 2026 losses that forced the sale of public holdings. Citadel purchased much of the remaining public portfolio. Situational Awareness reported a 439% net gain through June 2026 but faced margin pressure from declines in names like SK Hynix, Micron, SanDisk, CoreWeave and Nebius. The fund was backed by angel investors and firms including Jane Street and had significant Anthropic exposure, reportedly retaining roughly $5 billion in Anthropic shares.
