IREN joins Anthropic's portfolio: compute becomes the bottleneck and bitcoin miners become AI suppliers

By Investor's Business Daily · October 12, 2026.

IREN (ticker IREN), a company that started out mining bitcoin and now bills itself as an artificial intelligence infrastructure provider, has signed a multi-year cloud services agreement with Anthropic. The Information broke the news, citing anonymous sources, and Investor's Business Daily (IBD) picked it up. In the material available to us, neither Anthropic nor IREN has confirmed the terms. IREN's stock rose sharply early Monday.

According to IBD, the deal is part of Anthropic's latest round of data center contracts, which the outlet puts at about $530 billion. The figure comes from the cited source and we cannot verify it independently. The value and exact length of the IREN contract have not been disclosed either.

The contrast is striking. While IREN rose, data center and bitcoin mining stocks ended the day lower, according to IBD. In other words, the market isn't rewarding the sector as a whole. It's rewarding the names with a concrete AI contract behind them.

For sector context, IREN isn't the first in the group. In its recent coverage, IBD links to similar moves: TeraWulf signed a $19 billion data center lease with Anthropic, and Hut 8 announced a $9.8 billion deal. IREN, for its part, had raised its AI cloud revenue target.

**Our take.** The thesis is simple: compute, not the model, is the scarce resource, and labs are buying capacity wherever they can find it. Former bitcoin miners have exactly what's scarce: land, high-capacity power connections and experience running energy-intensive hardware. Repurposing them is faster than building from scratch.

That shifts the balance of power. The winner is the provider that already had megawatts locked in. Partly on the losing side is the narrative that bitcoin and AI compete for the same energy: in this case, AI seems to be winning that bidding war. Anthropic also gains flexibility by diversifying suppliers rather than relying on a single one.

There's a risk worth naming. The figures in these contracts are enormous relative to the labs' current revenues, and sooner or later that spending will have to be reconciled with their books. An announced contract is worth less than an executed one: data centers take years to build, and the stock's volatility reflects that uncertainty.

In the short term, this race for capacity strains the power grid and concentrates power in a few players. In the long term, the infrastructure going up today is what will make possible the models capable of accelerating drug discovery and science. That's the part of abundance to watch: that today's concrete and megawatts end up as useful, affordable capacity for many, not just a good quarter on the stock market.
