According to a document submitted to a US court, London-based distressed debt specialist Attestor Limited held approximately $394 million in FTX debt as of the end of January. This is the largest position among distressed debt investors, who made a large bet on FTX and are now likely to profit handsomely. Other creditors, according to the document and sources, include Baupost Group, Farallon Capital, and Oaktree Capital.

According to Cherokee Acquisition's pricing data, Attestor has been buying FTX claims since at least March 2023, when prices were around 20% of face value. According to LinkedIn, the investment firm hired Khing Oei as a senior advisor in charge of cryptocurrency claims work in the month FTX collapsed. Oei has experience trading distressed debt at Fortress and Goldman Sachs, as well as working in the cryptocurrency field.
