Riot’s shares jumped 25 per cent to US$24.40 in late trading on news of the deal with Anthropic. The developer recently signed a US$10 billion deal with a months-old infrastructure startup, Volta Infra, and agreed to buy nearly US$45 billion worth of computing from Elon Musk’s xAI in May. Riot Platforms said earlier on Monday that the agreement with the AI developer runs through June 2048 and that it expects the contract to generate US$9.1 billion in revenue. The developer has announced a separate deal with Advanced Micro Devices to build computing.
