\n\t\t\t\t\t\t\t\t\tRiot’s after-hours rally pushed its market value sharply higher, despite a quarterly net loss of $237 million.\t\t\t\t\t\t\t\t<\/p>\n<\/p><\/div>\n
Anthropic has agreed to pay Riot Platforms $9.1 billion over 20 years for computing capacity at the miner\u2019s Rockdale, Texas campus, according to people familiar with the matter who spoke to Bloomberg on Monday.<\/p>\n
Riot\u2019s stock jumped 24% in after-hours trading following the report, a sharp reversal after shares had already closed the regular session down more than 5%.<\/p>\n
Riot disclosed the agreement itself earlier Monday, describing a 20-year contract to supply 191 megawatts of capacity, enough to power roughly 143,000 homes at any given moment, to an unnamed \u201cleading frontier AI\u201d company.<\/p>\n
Bloomberg\u2019s sources, who asked not to be identified because the information is private, said<\/a> that the company is Anthropic. Neither Riot nor Anthropic has confirmed the identity publicly.<\/p>\n The stock swing was dramatic even by Riot\u2019s volatile standards. Shares closed regular trading at $19.40, down $1.12, before climbing to $24.13 in the after-hours session, a gain of $4.73 from the close. That put the after-hours price well above Monday\u2019s intraday range of $19.13 to $20.46 and closer to the stock\u2019s 52-week high of $30.32.<\/p>\n Volume topped 17.5 million shares against a daily average near 16.8 million, and Riot\u2019s market cap stood at roughly $7.3 billion heading into the move.<\/p>\n The company\u2019s latest earnings report also landed<\/a> Monday, adding another variable for traders parsing the after-hours action. Total revenue went up 14% year-over-year to $174 million, while there was a GAAP net loss of $237 million, translating to $0.68 per diluted share.<\/p>\n Per the report, Riot mined 1,587 BTC in the quarter, each costing $49,912 to produce, bringing its\u00a0holdings to 11,380 BTC valued at about $728 million at current rates.<\/p>\n Riot\u2019s move into AI hosting builds on a pattern that has been building for over a year. The company sold<\/a> 3,778 BTC in the first quarter of 2026 alone, worth about $289.5 million, while continuing to mine and expand its high-performance computing footprint.<\/p>\n That selling has continued since. In early August, on-chain trackers flagged<\/a> a 381 BTC deposit from Riot to an exchange, a move typically read as a precursor to a sale.<\/p>\nYou may also like:<\/h3>\n
