According to CoinMeta, Riot Platforms ( RIOT ) rose by more than 20% before trading on the U.S. stock market. The reason is that the Bitcoin miner announced a deal worth $9.1 billion with a leading cutting-edge artificial intelligence laboratory, aimed at accelerating its transformation into an artificial intelligence infrastructure provider. The agreement covers 191 megawatts of computing power located in Rockdale in Texas. Riot's business was once almost entirely focused on Bitcoin mining, but it is now transitioning towards AI infrastructure. The long-term lease provides more stable earnings than the volatility of Bitcoin block rewards. Riot also signed a lease with chip manufacturer AMD, increasing the Rockdale's AI capacity to 241 megawatts.
