Anthropic's $9.1 Billion Bet on a Bitcoin Miner's Data Center

Anthropic has struck a 20-year, $9.1 billion data center deal with Riot Platforms, the Bitcoin mining company, to secure 191 megawatts of critical IT capacity at Riot’s Rockdale, Texas campus. Disclosed in Riot’s Q2 2026 earnings report, the agreement is the single largest infrastructure commitment Anthropic has made through a third-party operator — and it underscores a tectonic shift in the AI industry’s approach to compute: partnering with former Bitcoin miners who already have the power, the land, and the permits.

The Deal in Numbers

The contract, formally a “Data Center Lease and Services Agreement,” runs through June 2048 — a full 20-year base term. The initial contract value is approximately $9.1 billion. But that figure could grow substantially: the lease includes two five-year extension options that, if exercised, would push the total potential contract value to roughly $16.1 billion.

Riot expects the agreement to generate cumulative net operating income between $7.3 billion and $8.2 billion over the base term alone. The 191 MW capacity will be delivered in phases: an initial 96 IT MW is slated for December 2027, with the full 191 IT MW deployment expected by June 2028.

The infrastructure is classified as a Tier 3 build-to-suit data center, meaning it is designed for high availability and redundancy — suitable for the always-on, high-density workloads that frontier AI model training and inference demand.

A Second Tenant at Rockdale

This deal makes Anthropic Riot’s second major data center tenant at Rockdale, following Advanced Micro Devices (AMD), which signed a lease for 25 MW announced on January 16, 2026. During Q2 2026, Riot successfully delivered the initial 25 MW to AMD on time and on budget.

Together, the two leases bring Riot’s contracted data center capacity at Rockdale to 241 MW, representing approximately $9.8 billion in long-term contracted revenue with two of the most important companies in the AI ecosystem — all signed within just over six months.

“In just over six months, Riot has now executed leases totaling 241 megawatts of capacity, representing approximately $9.8 billion of long-term, contracted revenue with two of the most important companies in the AI ecosystem,” said Jason Les, CEO of Riot Platforms. Les emphasized that Riot’s multi-gigawatt-scale power capacity, combined with its in-house data center development expertise, uniquely positions the company to convert market demand into compounding shareholder value.

Why a Bitcoin Miner?

The question naturally arises: why would one of the world’s leading AI labs turn to a company historically known for mining cryptocurrency? The answer lies in what Bitcoin miners already possess — and what new data center developers spend years trying to obtain.

Large-scale Bitcoin mining operations like Riot have spent years acquiring vast tracts of land near cheap, abundant power sources. They have secured fully approved electrical interconnections, substations, and power purchase agreements that can deliver hundreds of megawatts on demand. For a company like Anthropic, which needs enormous and growing amounts of compute to train and serve frontier AI models, partnering with a miner that already has a fully energized site can shave years off the timeline of building from scratch.

Riot’s Rockdale campus is a prime example. The facility leverages Riot’s existing, fully approved interconnection — meaning the power infrastructure is already in place and the regulatory hurdles for new transmission have already been cleared. That is precisely the kind of ready-to-build asset that AI companies are now scrambling to secure.

Financing the Buildout

To support the development costs of the new AI infrastructure, Morgan Stanley provided Riot with a $573 million interim financing facility. This facility serves as a bridge while an investment-grade credit backstop is finalized — a signal that Wall Street is increasingly comfortable underwriting the conversion of mining assets into AI-grade data centers.

The financing structure reflects the broader trend of financial institutions embracing the AI infrastructure boom. Major banks and asset managers now see compute not merely as an operational expense but as a new investable asset class, one with 20-year contracted revenue streams that look increasingly like traditional real estate or energy infrastructure.

Riot’s Q2 2026: The Pivot in Action

Riot’s Q2 2026 financial results vividly illustrate the company’s ongoing transformation. Total quarterly revenue reached $174.2 million, a 14% increase year-over-year. The newly established Data Center segment contributed $23.2 million — comprising $4.9 million in operating lease revenue and $18.3 million in tenant fit-out services revenue.

Meanwhile, the core Bitcoin mining business faced headwinds. Bitcoin mining revenue fell to $113.7 million for the quarter, down from $140.9 million in Q2 2025, driven primarily by lower average Bitcoin prices and an increase in the global network hash rate. Riot produced 1,587 Bitcoin during the quarter, and the average cost to mine a single Bitcoin, excluding depreciation, rose to $49,912 — up from $48,992 a year earlier.

The contrast is telling: Bitcoin mining revenue is declining while data center revenue is scaling rapidly from zero to tens of millions per quarter, backed by contracts worth nearly $10 billion. Riot’s stock jumped approximately 24% after the Anthropic deal was reported.

The Broader Pattern

The Anthropic–Riot deal is not an isolated event. It is part of a sweeping industry-wide pattern in which Bitcoin miners — from Riot and CleanSpark to IREN, Cipher Mining, and MARA Holdings — are repurposing their power-rich data centers for AI workloads. CleanSpark recently secured a $6.6 billion lease. CoreWeave, itself born from cryptocurrency mining, now operates 526 MW for clients including Galaxy Digital. The logic is simple: AI companies need power now, and miners have it.

The data center sector as a whole has exploded, growing from roughly 460 TWh in 2022 to a projected 1,000 TWh in 2026 — a 2.5x increase driven primarily by AI demand.

What It Means for Anthropic

For Anthropic, the deal represents another step in a massive infrastructure buildout. The company previously announced a $50 billion investment in American computing infrastructure in November 2025, including data centers with Fluidstack in Texas and other partners. It signed a separate 20-year lease with TeraWulf in Kentucky in July 2026. Now, with 191 MW locked in at Rockdale through 2048, Anthropic is methodically securing the multi-decade compute pipeline it will need to compete with OpenAI, Google, and Meta in the frontier model race.

The message is clear: in the AI arms race, whoever controls the power controls the future — and increasingly, that power is coming from the most unexpected of places.
