US stock trader 3X Long Labubu: SBF's old shares may have unrealized gains of 83x

A U.S. equities trader posting as 3X Long Labubu (@labubu_trader) said they bought Anthropic shares at a $18 billion valuation during FTX’s bankruptcy liquidation sales, crediting SBF as the “greatest angel investor.” FT reported that Anthropic’s underwriters are preparing to raise its IPO price above the $70–78 range, potentially lifting the valuation above $1.5 trillion—roughly 83x the $18 billion entry. FTX and Alameda had invested about $500 million in Anthropic in 2021, and the FTX estate sold the stake in batches in 2024. The disclosure matters because it highlights how FTX creditors and buyers of its estate assets could capture enormous upside from the AI startup’s IPO repricing. Next, watch the final IPO price range and valuation, and how the FTX estate’s earlier stake sales compare with the eventual listing outcome.
