Jane Street was once the second largest buyer of FTX's Anthropic shares

Jinse Finance reported that on February 24, Terraform filed a lawsuit against Jane Street for insider trading, putting Jane Street under the spotlight. The crypto industry has begun to scrutinize Jane Street in depth, examining events such as the 2022 Luna crash, the crypto winter triggered by the Luna collapse that led to FTX's bankruptcy, the fact that both FTX's founder and CEO came from Jane Street, and Jane Street's punctual sell-offs at 10AM during the US stock market opening in the second half of 2025. Jinse Finance also discovered that Jane Street was once the second largest buyer of FTX's Anthropic shares. In March 2024, FTX reached an agreement with a consortium of buyers to sell two-thirds of its 7.8% stake in AI company Anthropic for $884 million. The largest buyer in this Anthropic deal was ATIC Third International Investment Co., which spent nearly $500 million to acquire Anthropic shares and is closely linked to the UAE sovereign wealth fund Mubadala. The second largest buyer in the Anthropic deal was Jane Street, which spent nearly $100 million to acquire approximately 3.332 million shares of Anthropic (about 0.586% of Anthropic's total equity). Based on Anthropic's latest valuation of $380 billion in February 2026, the value of the Anthropic equity Jane Street acquired from FTX is now about $2.2 billion, a 22-fold increase. However, Jane Street did not stop there and subsequently participated in multiple rounds of financing for Anthropic.
