Anthropic has signed a $9.1 billion agreement with Riot, a company known for Bitcoin mining (using computing hardware to earn coins) and AI data center services, in a move aimed at locking in the computing power needed to support rising demand for its AI solutions. The development underscores how access to large-scale infrastructure has become central to AI expansion, and the source says market pricing is consistent with stronger confidence in Anthropic reaching a $1.25 trillion valuation. Investors are watching whether additional partnerships, funding rounds, changes in investment levels from Amazon and Google, Nasdaq Private Market reports, revenue growth, and enterprise contracts support that trajectory by December 31.
