A claim worth $20+ million recently sold for 52-53 cents at an October 20 auction. Smaller claims, ranging from $500,000 to $800,000, are trading between 30 and 40 cents. The uptick is attributed to recent clawback efforts and capital-raising activities, including Anthropic's $580 million Series B and Amazon's $4 billion investment. The FTX creditor coalition suggests that these valuations could fully compensate creditors. Concerns like KYC and AML issues still exist but are being addressed.
