Two Weeks, Two Major Infrastructure Deals for Anthropic

Anthropic closed out the first full week of August 2026 by announcing two major infrastructure moves within days of each other. First came Theseus Infrastructure, a joint venture revealed on August 10. The next day, August 11, brought confirmation of a multibillion-dollar contract with Riot Platforms. Together, the announcements show how quickly the company behind Claude is locking in dedicated compute capacity.

Theseus Infrastructure: Macquarie and GIC Come In as Equity Partners

According to a joint announcement from Anthropic, Macquarie Asset Management and Singapore's sovereign wealth fund GIC, and reporting from Bloomberg and Data Center Dynamics, Theseus Infrastructure is a new platform dedicated to developing, operating and leasing data centers at scale for Anthropic under long-term agreements. GIC and funds managed by Macquarie will fund most of the equity for each project, with an initial focus on the United States, while Anthropic has committed to covering any consumer electricity price increases caused by the facilities.

$9.1 Billion and 20 Years With a Former Bitcoin Miner

The second deal, revealed on August 11 by Bloomberg, CNBC and other outlets, is a 20-year contract worth $9.1 billion with Riot Platforms, a bitcoin miner that has started selling AI data center capacity. The deal secures Anthropic 191 megawatts of capacity at Riot's campus in Rockdale, Texas, with the contract running through June 2048. Two five-year extension options could push the total value to $16.1 billion. Capacity will be delivered in stages, with 96 megawatts expected by December 2027 and the full 191 megawatts by June 2028.

Third Major Compute Deal in Three Months

According to Bloomberg, the Riot deal is Anthropic's third major compute procurement in three months, bringing its total commitments to more than $60 billion. Before it came a $10 billion, six-year deal with Volta Infra Holdings for capacity at a data center in Norway, and a nearly $45 billion compute purchase from Elon Musk's xAI, closed in May.

Why Bitcoin Miners Are Turning Into AI Data Center Suppliers

The Riot Platforms deal illustrates a broader trend: bitcoin miners, which already own land, substations and large-scale power contracts, are increasingly repurposing that infrastructure to meet demand for AI data centers, according to CNBC's reporting on the shift in the crypto mining sector's focus. Riot's stock jumped more than 20% on the news, according to Cryptopolitan and Coindesk.

Why It Matters for Brazilian Agencies and SMBs

Locking in more than $60 billion in dedicated compute capacity within three months signals Anthropic is betting on sustained, growing demand for Claude in the years ahead, which should reduce the risk of capacity shortages for API customers over the medium term. At the same time, much of this dealmaking relies on structured financing and long-term debt, the same kind of leverage reports like Moody's have already flagged as a systemic risk for the entire AI sector. For Brazilian agencies that depend on Claude, the signal is positive in the short term, but it is worth keeping an eye on the broader financial health of the AI infrastructure chain.
