Core Scientific
NASDAQ: CORZCore Scientific still mines bitcoin. It just isn't really the point anymore — most of its buildings now host someone else's GPUs.

Who they are
Core Scientific was, for years, one of the largest bitcoin miners in North America — big enough that its 2022 bankruptcy (a casualty of the crypto winter and over-leveraged mining-rig financing) was industry news in its own right. It emerged from that restructuring under CEO Adam Sullivan and, rather than simply rebuilding the old mining business, pivoted harder and earlier into AI hosting than almost anyone else in the sector.
Headquartered in Austin, Texas, Core Scientific today describes itself first as a “leader in digital infrastructure” — bitcoin mining is now the second half of that sentence, not the first.
What they actually do
Host AI compute for hyperscalers, at serious scale. Core Scientific’s defining relationship is with CoreWeave, the AI cloud provider. What started in 2024 as a 200 MW hosting deal has been expanded option by option — 270 MW, then approaching 500 MW, then further still — with cumulative contract value running into the billions of dollars over 12-year terms. Notably, Core Scientific turned down a roughly $9 billion acquisition offer from CoreWeave itself, choosing to stay an independent landlord rather than be absorbed by its biggest tenant.
Mine bitcoin, on what’s left. The remaining slice of contracted power — a shrinking minority of the total — still runs bitcoin mining rigs. It’s real revenue, but it is no longer the growth story.
How they make money
Long-term, dollar-denominated HPC hosting contracts (the bulk of the value proposition now) plus residual bitcoin mining revenue on the capacity not converted to hosting.
Where it sits in the value chain
The bigger trend it’s riding
Every other miner in this value chain talks about “pivoting to AI” as a future plan. Core Scientific already did it. It’s become the reference case the rest of the sector points to — proof that a bitcoin miner’s real estate and power contracts can be worth more rented to an AI hyperscaler than run as a mining farm. The tension now is less “will this work” and more “what happens if the AI infrastructure boom cools before all this contracted capacity is fully built out.”
What to watch (not what to do)
What to watch (not what to do)
- Customer concentration. The overwhelming majority of the hosting story runs through one tenant, CoreWeave. That's a lot of eggs in one very large basket.
- Build-out execution. Contracted megawatts and delivered, revenue-generating megawatts are two different numbers. Watch the gap between them.
- Sentiment on the broader AI infrastructure trade. Some analysts have flagged 2026 as the year investors start demanding proof, not just contracts, from the AI data-center theme generally.
