Bitcoin Miner Riot Secures $9.1B Anthropic Contract

Bitcoin News

Bitcoin (BTC) miner Riot Platforms has converted part of its Texas power footprint into a long-term artificial-intelligence contract with Anthropic, marking one of the largest infrastructure agreements yet linked to the Bitcoin mining sector. The company’s Aug. 10 announcement described the counterparty as a major frontier AI laboratory and committed 191 megawatts of information-technology capacity at the Rockdale facility for 20 years. The capacity is roughly equivalent to supplying electricity to 143,000 U.S. households, according to the company’s disclosure. The agreement is expected to produce about $9.1 billion in revenue. The customer was identified as Anthropic on Aug. 11, one day after Riot’s initial corporate disclosure. The transaction also highlights a wider repricing of miners that control large power assets. Instead of relying only on block rewards and the volatile economics of ASIC mining, operators can sign predictable, multi-decade hosting agreements with AI customers. Market reaction was swift: Riot’s shares had fallen about 5.5% during regular trading before the agreement was identified with Anthropic, then rose roughly 25% in extended hours. The arrangement underscores how AI compute demand is now competing for the same substations, cooling systems and grid relationships that once served only proof-of-work fleets. For Bitcoin holders, the relevance is indirect but strategic: listed miners are becoming energy-infrastructure companies, and their balance-sheet decisions can affect how much BTC is held, sold or used to fund expansion. The structure resembles a utility-style contract: capacity is reserved for two decades, while revenue visibility improves independently of BTC’s price path. That matters because miner cash flow has historically swung with network difficulty, hash price and energy costs. By monetizing existing grid access, Riot can reduce dependence on spot hash economics while preserving optionality if mining profitability strengthens. The company did not disclose pricing per megawatt or the exact commencement date for the agreement.

The Anthropic agreement also reframes Riot’s relationship with Bitcoin as a treasury asset and funding source rather than only a core operating business. Company disclosures show persistent disposals across several quarters. In the first quarter of 2026, Riot sold 3,778 BTC for about $289.5 million, realizing an average $76,626 per coin, exceeding the 1,473 BTC it produced during the same period. Earlier disposals included 1,818 BTC for $161.6 million in December 2025 and 383 BTC for $37 million in November, leaving year-end holdings at 18,005 BTC. The firm also sold roughly 1,080 BTC in January to finance the $96 million purchase of 200 acres at Rockdale, a transaction explicitly funded from its balance-sheet holdings. Those sales suggest management prioritized liquidity for land, power and data-center readiness over maintaining maximum BTC exposure, particularly after the sector’s last bear market pressured margins. The pivot did not begin with Anthropic. Riot previously partnered with Advanced Micro Devices to establish its data-center line, starting with a 25-megawatt lease at Rockdale before AMD expanded to 50 megawatts. That arrangement contributed to $33.2 million in first-quarter data-center revenue. Rockdale’s 700 megawatts of grid interconnection and Riot’s wider 1.7 gigawatts of approved power capacity provide the scale needed for larger AI workloads. By replacing volatile mining income with contracted revenue, Riot is reducing sensitivity to hash price swings that can follow when BTC falls from an all-time high. The trade-off is clear: fewer coins on the balance sheet, but more predictable capital for the AI buildout. The extension options mean Anthropic can retain capacity for up to three decades if exercised, converting a mining site into a long-duration AI campus. For investors, the key metric shifts from BTC produced per megawatt to contracted revenue backlog, utilization and capital expenditure timing. It also raises the bar for rivals seeking similar power deals. The disclosures do not specify how much of the remaining Rockdale capacity is already reserved.

Together, the contract and the sales record show Bitcoin (BTC) miners evolving from pure hash producers into power intermediaries serving AI demand. COINOTAG’s analysis anchors this shift to Riot’s official announcement and investor-relations disclosure, which specify 191 megawatts, a 20-year term, about $9.1 billion in expected revenue and extension options up to $16.1 billion. What remains undisclosed includes per-megawatt pricing, the service start date and the split between Riot-owned equipment and customer-supplied GPUs. Those gaps matter because they determine how much of the headline value becomes near-term cash flow. The strategic signal, however, is confirmed: large Bitcoin mining sites are being re-rated as AI infrastructure assets.
