Cryptocurrency prices fell sharply on Monday, mirroring declines in the stock market, as IBM's stock plunged 11.2% following Anthropic's announcement about AI-driven COBOL modernization. Anthropic's Claude code promises to automate the modernization of COBOL systems, which are critical to many industries but lack new developers. This development has impacted IBM, traditionally reliant on consulting for such tasks, contributing to broader market declines. The Dow, S&P 500, and Nasdaq all dropped over 1%, with crypto markets following suit. Bitcoin fell 5% to $64,100, while Ethereum and Solana also saw similar declines. Major crypto-related stocks like Coinbase, MicroStrategy, Circle, and Galaxy Digital were down 4%-7%. However, bitcoin miners with AI infrastructure business models, such as Iris Energy, Cipher Mining, CleanSpark, and Hut 8, saw gains.
