A hedge fund that recently cut most of its public stock exposure has put another $400 million into a chip startup, betting that the next bottleneck in AI will be manufacturing rather than models.
TechCrunch reports that Situational Awareness invested the money into Source Foundry this week, bringing its total investment in the company to $500 million. The Wall Street Journal first reported the investment, according to TechCrunch. Source Foundry is described as a chip startup founded by Stanford researchers that aims to make chip manufacturing faster and cheaper.
The timing matters because Situational Awareness is not arriving from a position of calm. The fund, launched in 2024 and focused on AI, reportedly posted strong early returns before suffering steep losses as AI infrastructure stocks fell. TechCrunch says that by the end of July the fund sold off the majority of its public portfolio, with most of it going to Ken Griffin’s Citadel, while retaining its shares in Anthropic. Its assets under management fell from $20 billion to $10 billion, according to the report.
A large private bet on a fabrication-oriented startup after a public-portfolio retreat is a familiar pattern in the AI buildout: when listed “picks and shovels” reprice quickly, capital looks for assets where valuation is set in negotiated rounds and the story is measured in years. Semiconductors also offer a different kind of leverage. If Source Foundry can genuinely shorten manufacturing cycles or lower cost, it would matter to every downstream buyer of compute, from cloud providers to companies training large models, regardless of which model family is currently fashionable.
But manufacturing claims are also hard to audit from the outside. Unlike software benchmarks, a promise to make chip production “faster and cheaper” is mediated by equipment lead times, process yields, supplier qualification and customer trust—constraints that do not bend to a term sheet. The same investors who can move quickly into a private round still have to wait for foundry reality to show up in shipped wafers.
Situational Awareness was founded by Leopold Aschenbrenner, a former OpenAI researcher, according to TechCrunch. The fund’s latest check buys time for Source Foundry to prove that its pitch is more than a slide deck, and it buys the fund a narrative that does not depend on the next quarterly swing in AI infrastructure stocks.
The report notes the fund sold most of its public holdings to Citadel. The new money is going the other direction: into a company whose progress will be measured in factory milestones rather than ticker symbols.
