Riot Platforms Signs $9.1B Anthropic AI Lease — And It Changes What a Bitcoin Miner Is Worth

Liam Tremblay 9 min read

For years, Bitcoin mining companies were valued on a handful of variables: hash rate, energy cost per coin, balance sheet BTC holdings, and whatever the market decided to pay for exposure to Bitcoin’s price. Bitcoin itself supplied the upside and the volatility in roughly equal measure.

Riot Platforms just demonstrated there’s a fourth variable that’s starting to matter more than any of them: megawatts.

On Monday, Riot disclosed it had signed a 20-year compute lease for 191 megawatts of capacity at its Rockdale, Texas campus. Bloomberg subsequently confirmed, citing people familiar with the situation, that the unnamed “leading frontier AI lab” referenced in Riot’s SEC filing is Anthropic — the company behind the Claude family of AI models. The deal is expected to generate $9.1 billion in revenue over its base term through June 2048, rising to as much as $16.1 billion if both five-year extension options are exercised.

Riot shares jumped roughly 25% to $24.40 in after-hours trading, before giving back almost the entire gain in regular trading the following session. That whipsaw tells you something worth remembering: even a landmark contracted-revenue announcement doesn’t guarantee a clean re-rating in a single day. Markets price in a lot of future uncertainty alongside the good news.

What the Deal Actually Is

It helps to understand what Riot is selling here, because it’s not what most people assume when they hear “crypto company signs AI deal.”

Riot isn’t building GPUs or selling AI compute services directly. It’s an infrastructure landlord. The Rockdale campus has 700 megawatts of developed, grid-connected power capacity originally built for large-scale Bitcoin mining. Riot is converting that capacity for data centre tenants, who bring their own hardware and run their own workloads. The company supplies the power access, the physical space, the cooling, and the fibre. Anthropic supplies the chips and the AI.

That distinction matters enormously for how you think about the $9.1 billion number. This is closer to a commercial real estate deal than a technology services contract. Riot gets contracted cash flows with fixed or structured pricing over a 20-year term. Anthropic gets scarce, already-approved, grid-connected capacity in Texas at a moment when power access is genuinely the binding constraint on AI infrastructure expansion.

Rockdale’s existing grid interconnection is the real asset here. Building a new 191-megawatt interconnection from scratch in Texas right now — given ERCOT‘s tightened scrutiny of new power projects — would take years and face regulatory hurdles Riot has already cleared.

The Revenue Structure: What $9.1 Billion Actually Means

A few things to hold in mind before taking the headline number at face value.

The $9.1 billion is the expected base-term revenue over 20 years — not a lump sum payment, not guaranteed to the dollar, and not arriving tomorrow. Deployment happens in stages: Data Centre Dynamics reported that initial capacity of 96 megawatts isn’t expected to go live until December 2027, with full deployment of the 191 megawatts targeted for June 2028. Revenue ramps gradually as capacity comes online, not all at once.

The $16.1 billion figure requires Anthropic to exercise both five-year extensions. That’s a ceiling, not a forecast. Riot’s own disclosure anchors the base case at $9.1 billion, which is the number that should underpin any valuation work.

To fund the initial construction phase, Riot has put a $573 million interim financing facility in place through Morgan Stanley while longer-term investment-grade financing is finalized. That’s a meaningful capital commitment before a dollar of Anthropic revenue hits the income statement.

Riot Wasn’t Always in This Business

The company’s history is worth a paragraph because it contextualises just how much has changed. Riot Platforms started life as Bioptix, a biotech firm. It pivoted to Bitcoin mining in 2017, became one of North America’s largest mining operations, and spent several years being valued almost entirely as a leveraged Bitcoin play — shares went up when BTC went up, and down hard when BTC fell.

The Anthropic deal is the second major AI lease Riot has signed at Rockdale. The first, announced in January 2026, was with Advanced Micro Devices (AMD) for 25 megawatts of capacity, with options to expand to 200 megawatts and a total potential deal value of around $1 billion over its full term. Combined with Anthropic, Riot now has 241 megawatts of contracted capacity and roughly $9.8 billion in base-term contracted revenue across both tenants.

CEO Jason Les put it plainly in the company’s disclosure: “Today’s announcement of a landmark 20-year, 191-megawatt data centre lease with a leading frontier AI lab marks a defining moment in our evolution into a leading developer of large-scale data centres.” That framing is deliberate. Riot wants to be understood as a data centre developer first, Bitcoin miner second — and the Anthropic deal gives it the contracted revenue to back that story.

Activist investor Starboard Value, which had been pushing Riot to accelerate exactly this kind of AI pivot, appears to have gotten what it was asking for.

What This Means for How Bitcoin Miners Get Valued

This deal is part of a broader structural shift in how publicly traded Bitcoin miners are being assessed by markets and analysts.

Historically, a miner’s stock price tracked Bitcoin’s price with a leverage multiplier applied good for bull markets, brutal for bear ones. Mining economics network difficulty, halving-driven reward reductions, energy costs added another layer of volatility on top of BTC price risk. Miner stocks were, in effect, a high-beta version of simply buying Bitcoin.

That’s changing. Miners with large power capacity and grid-connected land are increasingly being valued for those physical assets, independent of what Bitcoin is doing. A 20-year lease with contracted pricing turns that portion of revenue into something that looks more like a long-duration bond than a mining operation. Riot’s mining revenue actually fell in Q2 2026  dropping to $113.7 million from $140.9 million a year earlier as network hashrate rose and BTC prices softened. The cost to mine one Bitcoin climbed to $49,912. Without the AI pivot, those numbers would be the entire story. With it, they’re a footnote.

Other miners are watching and following. Companies like Cipher Mining, Hut 8, and TeraWulf  and Canadian-listed miners including IREN, formerly Iris Energy — are all navigating some version of the same question: how much of our power capacity do we keep mining Bitcoin, and how much do we lease to AI tenants?

Anthropic’s activity elsewhere suggests the demand side of that equation isn’t going anywhere. Beyond Riot, the AI lab has struck a roughly $10 billion agreement with infrastructure startup Volta Infra Holdings and agreed in May to purchase nearly $45 billion in computing from Elon Musk’s xAI. That’s a company spending aggressively across multiple vendors to secure scarce compute capacity before competitors lock it up.

The Canadian Angle: What This Means for Investors Here

Canadians can’t buy Riot Platforms shares directly on the TSX — it trades on the NASDAQ under the ticker RIOT. But the deal has direct relevance for Canadian crypto investors in a few ways.

First, if you hold Bitcoin directly or through a Canadian ETF like the Purpose Bitcoin ETF (BTCC) or Evolve Bitcoin ETF (EBIT), the revaluation of large mining operations toward data centre economics is a meaningful story. Miners who previously were forced sellers of Bitcoin during downturns — because mining revenue was their only cash flow and they had to sell BTC to cover operating costs — are building contracted non-BTC revenue streams that reduce that pressure. Less forced selling from miners is a structural positive for Bitcoin’s price stability over time.

Second, IREN (formerly Iris Energy) is a dual-listed miner with significant Canadian roots that has been pursuing a similar AI infrastructure strategy in its own operations. It’s worth watching how the Riot-Anthropic deal affects how investors value IREN’s comparable capacity.

Third, from a regulatory perspective, this deal has nothing to do with Canadian rules — it’s a U.S. corporate transaction involving U.S. assets. But the broader question of how Bitcoin mining infrastructure gets classified and taxed, both in the U.S. and Canada, is one regulators are watching closely as miners generate more revenue from AI leasing than from block rewards. The CRA’s treatment of infrastructure-as-a-service revenue from what was originally a crypto mining operation is an open question if Canadian miners pursue similar strategies. For the basics of how crypto-related income is taxed in Canada, our Crypto Taxes Canada 2026 guide is a solid starting point.

What Still Needs to Be Resolved

A few open questions worth tracking as this story develops.

Neither Riot nor Anthropic has publicly confirmed the counterparty. Bloomberg’s sourcing is credible, but Riot’s official filings refer only to “a leading frontier AI lab.” Until one of them confirms publicly, there’s technically a thin layer of uncertainty on top of an otherwise detailed disclosure.

The ERCOT regulatory environment is a real variable. CNBC’s report cited Compass Point analyst Michael Donovan flagging that ERCOT’s increased scrutiny of new power projects in Texas could slow speculative build-outs across the state. For Riot specifically, this is probably a positive dynamic — already-approved capacity becomes more strategically valuable when new approvals are harder to get. But it’s worth watching how ERCOT policy evolves as AI infrastructure demand continues to compete with consumer power needs in Texas.

And the full revenue ramp is still two years away. December 2027 for the first 96 megawatts, June 2028 for full deployment. A lot can change between now and then — in AI demand, in Anthropic’s own trajectory, in power costs, and in how the broader AI infrastructure market gets priced. The contracted revenue is real, but it isn’t flowing yet.

The Short Version

  • Riot Platforms signed a 20-year, $9.1 billion compute lease with Anthropic (per Bloomberg) at its Rockdale, Texas campus, covering 191 megawatts of capacity.
  • This is infrastructure landlord economics, not tech services. Riot supplies power access, space, and cooling. Anthropic brings its own hardware. The structure creates long-duration, contracted cash flows largely independent of Bitcoin price.
  • Revenue ramps gradually — 96 MW by December 2027, full 191 MW by June 2028. The $9.1B is a base-term figure over 20 years, not a lump sum. The $16.1B maximum requires both extension options to be exercised.
  • Combined with the earlier AMD deal, Riot now has 241 MW contracted and roughly $9.8 billion in base-term revenue from two tenants at Rockdale.
  • This is part of a sector-wide shift in how miners are valued — megawatts and grid access are becoming as important as hash rate and BTC balance sheet holdings.
  • For Canadian investors: the deal affects Bitcoin price stability dynamics, has implications for IREN’s valuation, and raises open questions about how similar Canadian miner pivots would be treated under CRA rules.
