Bernstein's deal tracker logged a new AI-related Bitcoin mining contract every single week in July. By month's end, combined volume had crossed 7.5 gigawatts, representing $150 billion in multi-year commitments. That's not a trend. That's a sector quietly rewriting its own job description.

The deals on the table

Hut 8 set the tone with a 15-year, $9.8 billion lease for its AI data center campus. CEO Asher Genoot went on CNBC to say the deal validates the company's pivot away from pure Bitcoin mining. IREN followed with $2.8 billion in cloud services contracts signed with AI developers, locking in what had previously been speculative infrastructure value into actual revenue schedules.

TeraWulf went furthest. Its 20-year data center lease with Anthropic could generate roughly $19 billion in contract revenue over the full term. MARA Holdings, not to be left out, announced plans to acquire a Texas site carrying up to 2 gigawatts of capacity. Bernstein rates MARA at market perform while flagging most other Bitcoin mining stocks as outperform.

One factor quietly amplifying miner use: political resistance to new AI data center construction is spreading from Texas to Oregon to the federal level. That makes existing miner infrastructure, already built, already grid-connected, considerably harder to replicate than it was 18 months ago.

What the market is actually saying

The numbers get attention. Execution is what analysts keep circling back to. Seeking Alpha contributor The Curious Analyst put it flatly about IREN: "The biggest risk to my thesis is execution." That word applies across the board. A 20-year lease with Anthropic is a headline; the cash flow it generates over the next three years is the test.

Mining companies have genuine physical assets: land, power contracts, cooling infrastructure, grid interconnects that took years to negotiate. Converting those assets into reliable AI compute revenue is a different operational challenge than running ASICs. The companies that have signed these contracts are now in the business of building and running hyperscale data centers, not just hashing blocks. Some will manage it. Others will find the gap between announcement and delivery a lot wider than the press release suggested.
