Three companies tied to AI data centers have delayed or paused their IPOs within weeks of each other, a cluster of signals that investors are demanding more proof before funding the next phase of the AI build-out.
Data center companies were expected to account for roughly one-third of all IPO listings for the rest of 2026, according to the New York Times, making the timing of these stalls significant.
Three IPOs, Three Warnings
The stalled listings share a common thread: investors want operating track records, not revenue projections measured in decades.
SoftBank subsidiary SB Energy proposed what it describes as the world’s largest data center in Ohio, with OpenAI as the anchor tenant and Nvidia’s Jensen Huang committing to backstop leases at up to $105 billion. The company targeted a valuation of $50 billion or more, then hit a wall: investor pushback on that price and limited buyer demand pushed the offering to mid-to-late October at the earliest.
One problem stands out immediately. SB Energy has not yet operated a single data center, yet it projects a $439 billion revenue backlog over 20 years starting in 2028.
Holtec Nuclear Corporation planned to raise up to $900 million on the Nasdaq at a valuation of up to $10 billion, using the capital to develop small modular reactors intended to power data centers. Last week, the company suspended its IPO indefinitely, citing “uncertainty of data center development” in its own release.
Holtec CEO Krishna Singh described a “perfect storm” in which sentiment against the AI data center economy has dragged down enthusiasm for nuclear energy as a supporting technology, according to the Philadelphia Inquirer.
Power supplier Aggreko, which counts AI data centers among its key clients, has also slowed its IPO timing amid data center headwinds, rising interest rates, and broader economic uncertainty, though an offering may still arrive within a month.
The Numbers Behind the Nerves
Investors are repricing risk, not abandoning the sector entirely.
Three concerns are driving the pullback: thin operating track records, heavy reliance on single anchor tenants, and the sheer capital intensity of projects with payback periods measured in decades. When a company’s entire revenue thesis rests on one major tenant, a shift in that tenant’s business environment can unravel years of projected returns. Higher interest rates make those long horizons harder to justify at premium valuations.
Equinix and Digital Realty Trust, the only two publicly traded companies focused purely on building data centers, have each slipped roughly 1 to 2 percent over the past month. That modest decline signals a broader repricing of sector risk rather than a full retreat from the space.
The Neighbors Are Not Happy Either
Community opposition has already blocked an estimated $130 billion in projects in early 2026.
Surveys cited by NPR, Reuters, the Guardian, and USA Today show roughly two-thirds to 71 percent of Americans oppose new data center construction near their communities. Primary objections include water use, electricity demand, noise, and environmental impact.
In Ohio specifically, around 71 percent of residents would support a temporary construction ban, according to Reuters. Community pushback delayed or cancelled an estimated $130 billion in projects in the first three months of 2026 alone, per the Guardian.
Data centers have become a midterm election issue across the Midwest, with Democrats in particular attempting to channel the backlash into campaign platforms, according to Reuters.
Demand for AI computing is not in question. Meta, Alphabet, Amazon, Microsoft, and Oracle have committed over $1 trillion to infrastructure plans, and PIMCO estimates more than $5 trillion in spending will be needed by 2030 to support AI growth. Anthropic’s IPO is still expected this fall. Venture investors argue it is logically inconsistent to be bullish on AI while refusing to fund the infrastructure it runs on.
The question is not whether data centers get built. It is who pays, at what valuation, and whether the neighbors let them.
