According to Bloomberg, citing people familiar with the matter, Anthropic is the previously undisclosed customer behind a data center agreement announced by Riot Platforms. Riot Platforms shares surged about 25% to $24.40 in late Monday trading after closing the regular session at $19.40, reflecting growing investor interest in the Bitcoin miner’s expansion into AI data center infrastructure. For Riot Platforms, the Anthropic agreement represents another significant step in its diversification beyond Bitcoin mining. The company is seeking to capitalize on its existing power resources and data center assets as cryptocurrency miners increasingly explore opportunities in the rapidly expanding AI infrastructure market. Riot also said Monday that its new data center agreement contributed to second-quarter revenue exceeding market expectations, reinforcing the potential financial impact of its shift toward AI computing services.
