Nuclear startup Deep Fission announced that it was going public, hoping to garner investor support to build subterranean reactors to power AI data centers.<\/p>\n<p class=\"wp-block-paragraph\">Wait, didn\u2019t I already write that story? I could have sworn that I did.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">Oh right, <a href=\"https:\/\/techcrunch.com\/2025\/09\/08\/nuclear-startup-deep-fission-goes-public-in-a-curious-spac\/\" target=\"_blank\" rel=\"noopener\">I did<\/a>. Last September, Deep Fission said that it had gone public via a reverse merger with Surfside Acquisition, a Delaware shell company, a transaction in which a private company acquires an existing publicly listed entity to gain a stock market listing \u2014 raising $30 million in a concurrent private placement at $3 a share. Now it\u2019s seeking $157 million in a Nasdaq IPO at $24 to $26 a share. You can see my confusion.<\/p>\n<p class=\"wp-block-paragraph\">Turns out the previous public listing was public in name only. The reverse merger with Surfside was completed, making Deep Fission a reporting company with SEC obligations, but its stock never actually traded. The company had said it intended to list on the OTCQB, a marketplace for developing companies that don\u2019t meet the listing requirements of major exchanges like the NYSE or Nasdaq. But searches for Deep Fission on OTCQB don\u2019t return any results, and the company, in its S-1, denied that its stock had ever been publicly traded.<\/p>\n<p class=\"wp-block-paragraph\">In response to questions from TechCrunch, Deep Fission declined to comment, citing the quiet period before its IPO.<\/p>\n<p class=\"wp-block-paragraph\">Deep Fission\u2019s new public offering on Nasdaq is following the more traditional IPO route, with an offering that would value the company at up to $1.66 billion. It\u2019s a sizable figure for a company that one year ago was struggling to raise a $15 million funding round.<\/p>\n<p class=\"wp-block-paragraph\">Stranger still, the picture painted in the <a rel=\"nofollow noopener\" href=\"https:\/\/www.sec.gov\/ix?doc=\/Archives\/edgar\/data\/0001918102\/000110465926064074\/tmb-20260331xs1.htm#PROSPECTUSSUMMARY_380574\" target=\"_blank\">S-1 filed on May 20<\/a> is arguably bleaker than the one outlined in the <a rel=\"nofollow noopener\" href=\"https:\/\/www.sec.gov\/ix?doc=\/Archives\/edgar\/data\/0001918102\/000110465925125146\/tmb-20250930xs1a.htm#fact-identifier-565\" target=\"_blank\">December filing<\/a> with the SEC. Its timeline for turning on its first reactor has slipped. Further, back in December, it had hoped to achieve criticality \u2014 the point at which a nuclear chain reaction becomes self-sustaining \u2014 by July 2026. Now, it won\u2019t provide an estimate.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">Deep Fission does point out that it is drilling a test well. It has also lost a lot of money.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">One thing that hasn\u2019t changed: The new S-1 statement contains the same \u201cgoing concern\u201d warning present in December. If Deep Fission doesn\u2019t complete the IPO, it could run out of money in the next 12 months.<\/p>\n<p class=\"wp-block-paragraph\">In fact, the startup\u2019s financial position has worsened in recent months. As of March, its deficit had grown to $88.1 million from $56.2 million. In the last month and a half, the company\u2019s cash and cash equivalents declined by $6.4 million, or about 7%.<\/p>\n<p class=\"wp-block-paragraph\">On the technical front, Deep Fission says it is now prioritizing drilling, perhaps a tacit admission that making holes in the ground isn\u2019t as easy as it sounds.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">The company says it started drilling the first of three test wells <a rel=\"nofollow noopener\" href=\"https:\/\/www.deepfission.com\/news-media\/press-releases\/detail\/105\/deep-fission-kicks-off-historic-borehole-drilling-for-first-of-a-kind-nuclear-project\" target=\"_blank\">in March<\/a>. The well will be used to collect data \u201cup to 6,000 feet deep.\u201d At eight inches in diameter, it\u2019s quite a bit smaller than will be needed at commercial scale.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">The challenges in moving from a test well to commercial scale are likely to be significant. Deep Fission says it will need boreholes 30 to 50 inches in diameter and a mile deep, though it hasn\u2019t settled on a specific dimension yet. Even at the low end, its boreholes will be larger than what\u2019s typically used <a rel=\"nofollow noopener\" href=\"https:\/\/onepetro.org\/spe\/general-information\/1705\/Hole-geometry?utm_source=chatgpt.com\" target=\"_blank\">in the oil and gas industry<\/a>. And until Deep Fission knows how large of a hole it can drill, it\u2019ll have a hard time finalizing its reactor design.<\/p>\n<p class=\"wp-block-paragraph\">So what has changed since December that would spur a bigger offering at a nine-figure valuation? The company did receive an $80 million equity investment, including $20 million from data center developer Blue Owl, which also signed a non-binding MOU for future power plants. Still, that wasn\u2019t enough to stave off the going concern warning. It\u2019s possible that Deep Fission is sitting on some positive information that it omitted from the S-1, though that\u2019s hard to believe given what\u2019s riding on the IPO.<\/p>\n<p class=\"wp-block-paragraph\">It\u2019s more likely that the company and its backers are seeking to capitalize on investor excitement over fission power. Just last month, nuclear fission startup X-energy went public in an <a href=\"https:\/\/techcrunch.com\/2026\/04\/24\/x-energy-stock-pops-27-on-first-day-of-trading-following-upsized-ipo\/\" target=\"_blank\" rel=\"noopener\">upsized IPO<\/a>. But unlike Deep Fission, X-energy is generating revenue and is <a rel=\"nofollow noopener\" href=\"https:\/\/www.nrc.gov\/reactors\/new-reactors\/advanced\/who-were-working-with\/pre-application-activities\/xe-100\" target=\"_blank\">significantly farther along<\/a> in the Nuclear Regulatory Commission\u2019s licensing process \u2014 a contrast that serves as a useful reminder that in a sector where enthusiasm can run well ahead of technical and regulatory reality, valuation and progress aren\u2019t the same thing.<\/p>\n<p class=\"wp-block-paragraph\">It isn\u2019t exactly clear what factors are driving Deep Fission toward its IPO, but technological or commercial progress doesn\u2019t seem to be among them.<\/p>\n<\/div>\n<p><em>When you purchase through links in our articles, <a href=\"https:\/\/techcrunch.com\/techcrunch-affiliate-monetization-standards\/\" target=\"_blank\" rel=\"noopener\">we may earn a small commission<\/a>.
