Riot Platforms’ stock rises sharply in trading after hours and in pre-market following a report that the bitcoin miner has agreed to a $9.1 billion AI-related deal with Anthropic. The Block says the shares jump about 25% after hours, while CoinDesk reports a roughly 20% increase in pre-market trading.

Both outlets frame the news in terms of the size and long duration of the agreement. The Block reports the deal includes two five-year extension options that could increase the potential contract value to $16.1 billion. CoinDesk highlights that the miner’s 20-year agreement signals a broader shift toward monetizing computing and infrastructure for AI workloads rather than relying solely on cryptocurrency revenue.

While the coverage focuses on different trading windows and emphasizes different implications—contract value extensions versus an industry-wide AI infrastructure trend—both describe the same underlying reported transaction and its large projected scale.
