The hedge fund built by former OpenAI researcher Leopold Aschenbrenner has committed $500M to Source Foundry, a stealth startup trying to reinvent semiconductor manufacturing. The Wall Street Journal first identified the company as the mystery recipient, and Bloomberg confirmed the figure this week.
Source Foundry, backed by Sequoia Capital, is developing a chipmaking process it says is simpler, cheaper and faster than todays production methods. Sequoia partner Stephanie Zhan describes the problem as the chip wall: AI demand is growing on an exponential software curve while semiconductor manufacturing capacity expands on a linear equipment curve. The startup plans to lean on different underlying physics to speed up production and close that gap.
The funding came in two pieces. Situational Awareness, the fund Aschenbrenner founded, initially put in $100M and added a fresh $400M infusion this week. The timing is notable: the payout arrived days after the fund nearly collapsed in late July, when sliding prices in its technology stock portfolio triggered margin calls from lenders. Aschenbrenner agreed to sell part of the public holdings at a 10 percent discount to Citadel’s Ken Griffin to cover the demands.
The bet highlights how much money is chasing new chipmaking approaches as AI compute demand outstrips fab supply. It also exposes the concentrated risk the fund took on a private company right before its own liquidity crunch. Neither Source Foundry nor Situational Awareness commented on the reports.
