Riot Rents Its Bitcoin Mine to Anthropic for $9 Billion

A 20-year lease hands 191 megawatts to an AI lab — the clearest sign yet that power once used to secure Bitcoin now goes to whoever pays most for it.

On August 11, Riot Platforms — one of the largest publicly traded bitcoin miners in the United States — told investors it had signed a 20-year lease handing 191 megawatts of capacity at its Rockdale, Texas campus to Anthropic, the artificial-intelligence lab. The base value is $9.1 billion, rising to as much as $16.1 billion if extension options are exercised through 2048. Riot’s stock jumped roughly 17 to 20% on the news. The company that built its identity mining bitcoin had just become, in one contract, an AI landlord.

The structure of the deal makes the shift literal. Riot will build the data center to Anthropic’s specifications and supply the building, the power connections, the cooling and the operations. Anthropic brings its own servers and AI chips. The first 96 megawatts are scheduled to energize in December 2027, the remaining 95 in June 2028. To fund early construction, Riot arranged a $573 million interim facility through Morgan Stanley. Anthropic is the second tenant at Rockdale, following a hosting agreement Riot struck with AMD in January.

The math that turned miners into landlords

The reason is unsentimental economics. A trillion-dollar AI company generates far more revenue per megawatt than an ASIC grinding out block rewards, so it can simply outbid a miner for the same electricity. Riot disclosed that its direct cost to produce a single bitcoin rose to $49,912 in the second quarter — uncomfortably close to a spot price hovering in the low $60,000s. Against that squeeze, twenty years of contracted rent from a credit-worthy tenant is the safer trade than betting the campus on hashprice and the next halving.

The same cheap power that secured Bitcoin now has a higher bidder. The miners are taking the money.

A sector-wide pivot

Riot is the loudest example, not the only one. Keel Infrastructure reported a $140.8 million operating loss for the quarter after shutting mining rigs, liquidated 1,085 BTC for about $75 million to retire debt and fund a 96 MW data center in Quebec, and said it plans to sell its remaining 1,861 coins by the end of 2026. Hyperscale Data sold 685 BTC for $43 million to finance a high-performance-computing site in Michigan, leaving just 275 coins in its treasury. Soluna Holdings won ERCOT approval to energize an 83 MW wind-powered site in South Texas. One after another, miners are converting bitcoin on the balance sheet into concrete and transformers for AI.

The competition for electrons is now the binding constraint. Texas has frozen roughly 474 gigawatts of pending data-center grid-connection requests — a queue so large it has become an asset in itself. Miners like Riot that hold pre-approved interconnection slots are sitting on scarce, valuable real estate in the power market, whether or not a single bitcoin is ever mined there again. Nvidia’s reported $3 billion investment in SB Energy to secure power for a proposed $100 billion OpenAI data center in Ohio is the same story at hyperscaler scale.

What it means for the network

Bitcoin’s security budget rests on miners being willing to spend real energy to defend the chain. If the most efficient operators increasingly find it more profitable to rent their megawatts to AI than to hash, the marginal miner gets smaller, more distributed, and more dependent on cheap or stranded power that no one else wants. That is not an immediate threat — network hashrate still sits near record highs, around 919 exahashes per second — but it is a slow reordering of who mines, and why.

The optimistic read is that diversification keeps miners solvent through bear markets, so they survive to hash another cycle. The wary read is that a public miner’s incentives now point away from bitcoin, toward whatever tenant pays most for power. Riot’s $9.1 billion answer suggests the wary read is winning.

Why it matters: the cheap energy that underwrites Bitcoin’s security now has a richer suitor, and the miners are choosing the rent check.
