Silicon Valley Engineer Acquires Anthropic Stake at $18 Billion Valuation During FTX Liquidation

TechFlow reported that on November 11, U.S. equities trader 3X Long Labubu (@labubu_trader) posted on X that he bought Anthropic shares at a $18 billion valuation during FTX's bankruptcy liquidation sales, jokingly thanking 'the greatest angel investor' SBF.

Previously, the FT reported that Anthropic's underwriters were preparing to raise the IPO price above the $70–$78 range, potentially lifting its valuation to more than $1.5 trillion. On this basis, that would represent an increase of about 83x over the $18 billion purchase valuation.

Public records show that 3X Long Labubu is a Silicon Valley AI engineer working on AI inference and training, trades U.S. AI and semiconductor stocks in his spare time, and is skilled at analyzing market structure, leverage, and options flows. He has about 77,000 followers on X. His account name comes from collecting Labubu dolls for his daughter.

For context, SBF's FTX and Alameda invested about $500 million in Anthropic in 2021. After FTX's bankruptcy, its estate administrators sold the stake in tranches in 2024.
