Why Core Scientific investors walked away from CoreWeave’s $9bn AI infrastructure takeover

Core Scientific Inc. has officially walked away from its proposed $9 billion all-stock merger with CoreWeave Inc., after shareholders overwhelmingly voted against the deal in a special meeting held on October 30, 2025. The decision, which brings a dramatic end to one of the year’s most closely watched artificial intelligence infrastructure transactions, was confirmed in a regulatory filing submitted by Core Scientific shortly after the vote.

Originally announced in July 2025, the proposed merger was pitched as a transformative play in the AI and high-performance compute (HPC) infrastructure landscape. CoreWeave, a GPU cloud specialist and infrastructure partner to OpenAI, Microsoft Corporation, and Meta Platforms Inc., had planned to acquire Core Scientific through an all-stock transaction that would give Core Scientific shareholders just under 10 percent ownership in the combined entity. The deal also aimed to consolidate over 1.3 gigawatts of data center capacity under one roof while eliminating $10 billion in future lease obligations from CoreWeave’s balance sheet.

But despite the ambitious vision, shareholders were unconvinced. The structure of the offer, particularly the fixed exchange ratio, became a flashpoint of contention. Under the terms, Core Scientific shareholders would have received 0.1235 shares of CoreWeave for every Core Scientific share they held. This effectively pegged the value of Core Scientific at a significant discount, triggering concern among institutional holders that they were giving up too much in exchange for future uncertainty.

Why did Core Scientific investors reject the $9 billion CoreWeave merger despite booming AI infrastructure demand?

Proxy advisory firm Institutional Shareholder Services was among the first to publicly recommend a vote against the transaction. In its report, ISS argued that the all-stock nature of the merger left Core Scientific investors overly exposed to volatility in CoreWeave’s share price. It also emphasized that Core Scientific had credible upside potential as a standalone player, particularly given the rapidly growing demand for high-density AI compute infrastructure.

Those concerns were echoed by Two Seas Capital LP, a major shareholder with more than a six percent stake in Core Scientific. The investment firm publicly opposed the merger, stating that the proposed terms significantly undervalued the company’s current and future contributions to the AI data center ecosystem. Analysts tracking the transaction estimated Core Scientific’s standalone value could reach between $30 and $40 per share—far above the implied valuation under the CoreWeave offer.

The shareholder base’s rejection reflects a broader skepticism around stock-for-stock mergers in high-volatility, growth-stage sectors. In this case, the question was not whether the companies were strategically aligned, but whether the deal fairly captured Core Scientific’s value and preserved shareholder upside.

How CoreWeave planned to gain strategic advantage through vertical integration

From CoreWeave’s perspective, acquiring Core Scientific was part of a much broader strategy to vertically integrate and secure long-term access to compute infrastructure. The company has built its reputation by offering GPU-powered cloud services to some of the most demanding AI workloads in the market. But its heavy reliance on leased data center capacity meant future margins were vulnerable to price escalation.

By acquiring Core Scientific—one of the largest owners of power-dense data centers in the United States—CoreWeave hoped to gain direct control over physical infrastructure, reduce its reliance on third-party lease contracts, and expand capacity to meet growing demand from clients such as OpenAI and Meta Platforms Inc. The proposed merger would have created a new AI infrastructure giant with massive scale, operational synergies, and strong cost advantages.

But the logic of the merger clashed with market sentiment. Investors were wary of combining two companies with different financial profiles and exposure risks. While CoreWeave has strong demand-side traction in AI, Core Scientific has only recently pivoted away from crypto mining, a legacy that still clouds its market narrative. Critics of the deal believed CoreWeave was leveraging its equity to acquire undervalued infrastructure, rather than presenting a true partnership of equals.

How investor sentiment split after the CoreWeave–Core Scientific deal collapse and what it means for market confidence

The immediate market reaction to the deal’s collapse reflected those diverging expectations. Shares of Core Scientific (NASDAQ: CORZ) rose by approximately 4 percent in the hours following the termination announcement, closing at $21.62 after opening the day at $20.46. Investors appeared to welcome the company’s return to autonomy and its continued push toward AI infrastructure specialization.

CoreWeave Inc. (NASDAQ: CRWV), on the other hand, saw its shares fall nearly 5 percent to $135.13 as investors recalibrated growth projections that had factored in the merger’s synergy assumptions. For CoreWeave, the collapse of the transaction means a return to capital-intensive expansion—either organically or through smaller bolt-on acquisitions.

For both companies, the failed merger now serves as a reset moment. It calls into question not just the feasibility of mega-deals in AI infrastructure, but also the valuation frameworks and shareholder alignment models that support them.

Is this the end of CoreWeave’s M&A ambitions—or just a tactical pause?

Following the vote, CoreWeave Chief Executive Officer Michael Intrator released a statement acknowledging the outcome and reaffirming the company’s intent to maintain a commercial partnership with Core Scientific. He also hinted that the company would continue exploring “opportunistic and strategic M&A” as it seeks to scale capacity and meet the compute demands of next-generation AI applications.

While the $9 billion transaction is now off the table, analysts believe CoreWeave is unlikely to remain on the sidelines for long. The company is reportedly evaluating other acquisition targets across the AI infrastructure stack, including specialized data center operators and power-optimized GPU colocation providers.

The broader takeaway, however, is that even AI infrastructure—one of the hottest segments in technology—cannot defy the fundamental rules of M&A: valuation, risk alignment, and shareholder trust matter more than buzzwords. In a rising-rate environment where equity valuations are under pressure, the days of high-premium, all-stock deals sailing through uncontested may be over.

What this deal’s failure reveals about M&A dynamics in AI data infrastructure

The collapse of the CoreWeave–Core Scientific merger reflects a deeper shift in how shareholders are evaluating deals in the AI and data infrastructure space. Despite bullish top-line narratives, investors are demanding more rigorous deal structures, clearer financial protection mechanisms, and greater transparency in integration plans.

Notably, this deal faltered even with clear strategic logic and sectoral alignment. That suggests the bottleneck was not vision, but execution. All-stock mergers, particularly those without collars or downside protection, are becoming harder to justify in sectors where market volatility can swing valuation models in weeks.

For Core Scientific, the failed merger gives it breathing room to execute its independent strategy. It remains one of the few public companies with substantial owned compute infrastructure tailored for AI workloads. If management can demonstrate steady revenue growth, improved capacity utilization, and customer diversification, the company could re-rate significantly in public markets—or attract new offers under more favorable terms.
