Core Scientific Shareholders Reject $9B CoreWeave Deal, Choosing Power Optionality Over AI Pivot

Investors at Core Scientific just shut the door on a $9 billion stock-for-stock merger with AI compute provider CoreWeave, voting Thursday to reject the proposal that was announced in July. The company disclosed Friday that the vote failed to reach the required approval threshold. Markets responded with a mild divergence: CoreWeave shares fell nearly 4% Thursday, while Core Scientific ticked 0.3% higher.

The crux here is control over power. The deal would have handed CoreWeave access to roughly 1.3 gigawatts of gross capacity across Core Scientific’s nationwide data center footprint, with an option to add another 1 GW over time. For an AI cloud business hungry for high-density compute, that scale is a strategic accelerant. For a Bitcoin miner navigating post-halving margins, that same capacity is optionality—negotiating leverage with customers, counterparties, and grids.

CoreWeave’s leadership publicly emphasized how the combination could expand its ability to serve AI customers. Core Scientific’s management had pitched the merger as a way to accelerate delivery of top-tier infrastructure for AI workloads while maximizing shareholder value. After the vote, CoreWeave’s CEO said the company respects stockholders’ views and intends to continue the commercial relationship. That last line matters: a deepening contract-based partnership often preserves upside without giving away corporate control at a disputed valuation.

Why investors balked: the price and the paper. Shareholders believed the transaction undervalued Core Scientific. An all-equity structure introduces ongoing exposure to CoreWeave’s stock—risk that many investors are reluctant to take at a time when AI-exposed names can re-rate quickly, up or down. Selling into another company’s multiple can be attractive when the premium is obvious; when that premium looks thin—or cyclical—holders tend to keep their chips on the table.

The operating backdrop supports that stance. Bitcoin mining has become more capital intensive and competitive, and the April 2024 halving cut the block reward from 6.250 BTC to 3.125 BTC per block. Even with Bitcoin’s price strength, unit economics tightened, pushing miners to monetize power in more creative ways: long-term colocation contracts, responsive load programs, and selective forays into high-performance computing. But AI data centers are not a copy-paste of mining sites. They demand higher power density and far more complex thermal management and facility engineering than standard ASIC farms. Retrofitting at scale is possible, but it is expensive, sequencing-heavy, and unforgiving on timelines.

Shareholders seem to prefer incrementalism over transformation risk. Keeping the asset base intact allows Core Scientific to:

- Extract better terms from AI/HPC customers via colocation and offtake agreements, rather than surrendering equity value in a wholesale merger. - Retain upside to future Bitcoin cycles, where hashrate dynamics and price can swing margins quickly. - Sequence capex and thermal upgrades discipline-first, matching real demand instead of building to a single buyer’s spec. - Diversify revenue without importing another company’s equity volatility.

There’s also a governance read-through. In a market where miners are often pressured to “become AI companies,” this vote signals that some holders will only endorse that pivot at a price that squarely reflects the scarcity of grid-tied megawatts. Power is the moat. Whoever controls it controls the option to mine, to host, or to negotiate with AI tenants—option value that is hard to mark correctly in an all-stock deal.

Expect both firms to keep working together commercially. CoreWeave still needs capacity; Core Scientific still benefits from recurring, non-cyclical hosting revenue. The difference now is who owns the upside. With 1.3 GW live and another potential gigawatt on the horizon, Core Scientific retains the right to allocate those electrons between Bitcoin mining and AI compute on its own timeline—a choice that, in this macro, may be worth more than a quick premium.
