Wall Street Grows Cautious on Data Center IPO Boom
nashnova research
SoftBank's SB Energy, nuclear firm Holtec, and temporary-power provider Aggreko have all delayed or shelved IPO plans, cracking the valuation consensus around data centers — a sector once expected to account for a third of second-half IPO volume is now a litmus test for market confidence.
Three companies hit the brakes — what happened?
SoftBank's SB Energy planned to IPO this month at a target valuation of $50 billion or above, funding what would be the world's largest data-center project in Ohio. Underwriters could not find enough buyers within the agreed price range, and the listing was postponed.
Nuclear firm Holtec announced an indefinite suspension of its Nasdaq listing, which had targeted up to $900 million in proceeds at a valuation of up to $10 billion. The company named "uncertainty in data-center development" as the primary reason.
Aggreko, which supplies temporary power to AI data centers, mining operations, and live events, has also slowed its IPO process amid unclear data-center prospects, rising rates, and macro uncertainty.
This means → it is not one company's problem. The entire data-center supply chain — power, nuclear, construction — is hitting buyer hesitation at the same time.
Why did investors pull back so suddenly?
The most direct cause: a widening valuation gap. Sellers see data centers as non-negotiable AI infrastructure and price accordingly; buyers worry about policy and demand uncertainty and refuse to pay a premium for a long-dated story.
AI industry executives issued a wave of warnings last week, calling for a slower pace of technology development — adding another layer of doubt over AI infrastructure spending.
In plain terms = sellers think "AI must be built"; buyers think "let's wait and see." The two sides' views of the future have diverged, so the price cannot meet in the middle.
How big is the pushback from communities and politics?
Communities across the U.S. continue to resist data centers, especially large-scale projects expanding into rural areas — high power consumption and land use are the core flashpoints.
With midterm elections approaching, data centers have become a bipartisan voter concern. Several states have already moved to restrict data-center construction.
This means → the financing headwind is not just a valuation disagreement. There is a political-risk layer on top — whether projects can be built, and built on schedule, now carries more uncertainty.
Has the underlying demand actually weakened?
Demand itself has not faded. PIMCO estimates AI infrastructure will require more than $5 trillion in investment through 2030.
Meta, Alphabet, Amazon, Microsoft, and Oracle have collectively committed over $1 trillion to their own infrastructure.
Yet only Equinix and Digital Realty Trust trade as pure-play public data-center companies in the U.S.; both saw their share prices drop 1–2% this month.
In plain terms = the demand is real, and the capital commitments are real, but investors willing to hand money to new companies via an IPO do not have enough confidence right now.
What comes next?
More than a dozen bankers, lawyers, and investors estimated that data-center-linked companies were expected to account for roughly a third of remaining 2026 IPO volume. With those plans stalled, the pace and scale of the second-half IPO market may fall short of expectations.
Theory Ventures investor Tomasz Tunguz noted: "The scale they need to build is enormous, so they need access to every major capital market."
Anthropic's IPO remains on track for this autumn. This reflects a growing split in market confidence between "pure AI companies" and "AI infrastructure companies" — whether Anthropic can list smoothly will be the key test of whether confidence has truly recovered.
