Nuclear IPO Pulled as AI Data Center Hype Cools: SMR Stocks at Crossroads

Sep 17, 2026

💡 Key Takeaway

Holtec's canceled IPO reveals shifting market sentiment on AI data centers, but rising government support for SMRs could reignite the sector.

Holtec Scraps IPO Amid AI Data Center Pullback

Holtec International, a nuclear components supplier, abruptly canceled its highly anticipated IPO this week, which was expected to raise $900 million. The company's CEO cited a sharp market turn against the AI data center economy, to which nuclear power is closely tied. Holtec had planned to use the proceeds to pivot toward restarting a Michigan nuclear facility and developing small modular reactors (SMRs).

The cancellation sent ripples through the SMR sector, where stocks like Oklo and NuScale Power have already been battered, down nearly 50% and 45% year-to-date, respectively. However, Holtec hasn't abandoned its public listing plans entirely; it retains its IPO registration and may attempt to float again within three to six months if market conditions improve.

Despite the near-term setback, the underlying driver for nuclear power—AI's insatiable demand for low-carbon baseload energy—remains intact. McKinsey estimates $7 trillion will be invested globally in AI data centers by 2030, underscoring the long-term need for reliable power sources like SMRs.

Government Support and Cost Shifts Favor SMRs

The Holtec IPO cancellation highlights the market's waning appetite for AI data center-related investments, but it also underscores a critical distinction: Holtec is primarily a supplier, not an SMR developer. Its pivot to SMRs was opportunistic, and the canceled IPO may not reflect fundamental challenges for pure-play SMR companies like Oklo and NuScale. In fact, recent government actions could bolster their prospects.

In early September, the European Investment Bank extended a €40 million loan to Steady Energy, a Finnish SMR developer, signaling growing institutional support. More significantly, the U.S. House passed the Ratepayer Protection Act by a landslide 417-3 vote on Sept. 16. This legislation requires large energy users like data centers to pay for their power needs directly, rather than passing costs to all utility customers. This shift makes dedicated power sources like SMRs more attractive, particularly for Oklo, which targets AI and data center companies directly, while NuScale focuses on utilities.

Both stocks jumped roughly 10% on the news, indicating that investors recognize the potential tailwinds. However, the sector remains volatile and sensitive to broader market sentiment on AI and tech spending. The key question is whether government support and the inherent need for reliable power can overcome near-term market pessimism.

The SMR sector faces near-term headwinds from cooling AI data center hype, but long-term fundamentals and government support remain strong, making it a wait-and-see opportunity.

While Holtec's canceled IPO signals investor caution, the underlying demand for reliable, low-carbon power from AI data centers is undeniable. Government policies like the Ratepayer Protection Act and EU loans are creating a favorable backdrop for SMR developers. However, until market sentiment stabilizes and concrete orders materialize, SMR stocks may continue to trade with high volatility.

What This Means for Me

means-for-me
If you hold SMR stocks like Oklo or NuScale, expect continued volatility as the market digests mixed signals from AI data center spending and government support. Investors with broad clean energy or tech exposure should monitor policy developments and AI capital expenditure trends, as these will drive the next leg for nuclear. Consider position sizing carefully, as the sector remains speculative and sensitive to sentiment shifts.

Stock to Watch

StocksImpactAnalysis
SMR
Neutral
NuScale Power is down 45% YTD but benefits from government support and the Ratepayer Protection Act. Its utility-focused model may see slower adoption than direct-to-data-center strategies, but it remains a key SMR player.
OKLO
Neutral
Oklo is down nearly 50% YTD but is well-positioned with its direct-to-AI-data-center strategy. The Ratepayer Protection Act could accelerate its pipeline, though market sentiment remains a headwind.
