Named after the essay its founder published in 2024, the fund put investor money into the listed companies that build and power AI infrastructure, and used borrowed money to do it. Reports put its leverage on the public book near four times. After AI shares fell hard in July 2026 the leveraged portion was taken over by Citadel, while a private stake in Anthropic stayed with the fund because private holdings cannot be margin called.
