Bitcoin Miner Riot Signs $28B Compute Deal with Anthropic; Financing Rate May Reach 12%
nashnova research
Bitcoin miner Riot Platforms signed a $28 billion compute-lease deal with Anthropic, converting its Texas mining site into an AI data center; but the project's financing rate may reach 12%, and the real financial test won't arrive for another two years.
What is this deal, exactly?
Riot is converting its bitcoin mining site in Corsicana, Texas into a 910-megawatt AI compute campus and leasing it to Anthropic.
The split: Riot supplies land and power infrastructure; Anthropic installs and operates its own computing equipment. Riot is essentially a landlord.
The initial contract runs 15 years, with phased delivery planned by July 2028. Riot expects average annual rent of roughly $1.8 billion.
This means → a bitcoin miner is reselling its most valuable asset — cheap, large-scale power access — to the AI industry.
Who covers the $5.5 billion build cost?
Total project cost is roughly $5.5 billion. Riot bears about $1.8 billion for site and power buildout; it must also repay Anthropic up to $3.6 billion for data-center facility costs.
In plain terms = Anthropic fronts the money to build the data-center hardware; Riot pays it back over time from rental income — think "renovate now, repay in installments."
Riot plans to borrow most of the capital. Its financing model assumes lenders cover 80–90% of total cost, leaving Riot to contribute roughly $500 million to $1.1 billion in cash.
What does a 12% rate really mean?
The deal's core terms show Riot may repay Anthropic's construction costs at a rate of 12%.
This means → at maximum leverage, the interest burden alone is substantial — and that is before Riot's own bank-loan interest.
The financing window does not open until 2027. The rate environment and capital markets' pricing appetite for AI-infrastructure assets at that point will directly determine the deal's true financial cost.
This reflects a deeper signal: AI compute demand is red-hot, but the financing terms to pay for it are not cheap — the cost of capital is the key variable in whether "mining-to-AI" conversions actually make money.
