Geothermal developer Fervo Energy priced one of the largest U.S. IPOs of 2026 on May 12, selling 70 million Class A shares at $27.00 — above the upwardly revised marketing range — to raise approximately $1.89 billion before fees. The Houston-based company will begin trading on Nasdaq under the ticker FRVO, with the offering set to close May 14. Underwriters hold a 30-day option to buy an additional 10.5 million shares, which would push gross proceeds to roughly $2.17 billion at the IPO price.
The pricing caps a textbook IPO escalation: launched May 4 at 55.6 million shares and a $21–$24 range, upsized May 11 to 70 million shares at $25–$26, and finally priced above that raised range at $27. That kind of two-step lift typically signals deep oversubscription — and it lands Fervo among the biggest U.S. listings since Cerebras Systems in early May.

The price walk: from $21 to $27
The upsize and overshoot tell the story. Three steps in eight calendar days:
The deal also got bigger as it got pricier: share count jumped from 55.6 million to 70 million, a 26% bump that underwriters typically reserve for books that are multiples oversubscribed. Counting the greenshoe, Fervo could raise more than $2.17 billion — a top-five U.S. IPO year-to-date by proceeds.
Why investors are paying up: AI power demand
Fervo is not a typical clean-energy story. The company applies oil and gas drilling techniques — horizontal drilling and distributed fiber-optic sensing — to enhanced geothermal systems (EGS), which extract heat from hot dry rock in places traditional geothermal could not reach. The pitch to investors is simple: deliver 24/7, dispatchable, zero-carbon electricity at scale, and you have a near-perfect match for AI data centers that need round-the-clock baseload power.
That demand is real and visible in capital markets. U.S. Energy Information Administration projections show electricity load growth accelerating, and hyperscalers including Google and Microsoft have publicly contracted geothermal capacity to power AI workloads. Investors voting with their wallets on FRVO are buying a leveraged play on that thesis without the intermittency overhang attached to solar and wind.
How Fervo stacks up against 2026 AI-infrastructure IPOs
Fervo’s $1.89 billion lands second behind Cerebras Systems’ $3.5 billion AI-chip IPO and edges past the Blackstone Digital Infrastructure Trust’s $1.75 billion data-center REIT — three sides of the same AI-build-out trade. Cerebras sells the silicon; Blackstone owns the buildings; Fervo aims to keep them powered.
What the syndicate signals
The bookrunner lineup is loaded toward U.S. bulge-bracket banks with deep energy and infrastructure desks. J.P. Morgan, BofA Securities, RBC Capital Markets, and Barclays lead as joint lead bookrunning managers; the broader syndicate includes Baird, BBVA, Guggenheim, MUFG, Société Générale, William Blair, Piper Sandler, and the Wolfe | Nomura Alliance. That breadth suggests Fervo is being marketed both to U.S. infrastructure and clean-energy specialists and to international energy investors who already finance oil and gas projects.
Macro backdrop: a tough tape for risk
The pricing landed into a wobbly day for risk assets. Hot April CPI data released earlier in the week, plus April core PPI running at a 5.2% year-over-year clip per the May 13 release, has pushed the front end of the curve back up and lifted the 30-year yield close to 5.0%. According to the Federal Reserve H.15 release, the 10-year traded at 4.42% and the 30-year at 4.98% as of May 11, 2026 — the kind of backdrop that usually shrinks, not expands, IPO size. Fervo getting an upsize-and-overshoot through this tape is itself a data point about the strength of demand for AI-power exposure.
What to watch from here
- First-day pop and lockup expiry. Aftermarket trading on May 13 will tell how much of the demand was real money versus flippers. The standard 180-day lockup will be the next supply event.
- Greenshoe exercise. Watch the underwriters’ 30-day option on the additional 10.5 million shares — full exercise pushes proceeds toward $2.17 billion and adds visible support to the aftermarket.
- Project economics. Fervo’s pitch hinges on enhanced geothermal scaling and unit cost coming down. The first post-IPO 10-Q will be the first look at how its Cape Station development and offtake pipeline are translating into revenue and cash flow.
- Read-across to other clean-power IPOs. Successful pricings normally pull peers off the bench. Watch for nuclear small-modular-reactor and grid-storage filings to re-engage the bookbuilding window.
Bottom line
Pricing 26% above the original launch midpoint and upsizing 26% on share count is what hot IPOs look like — and it lands Fervo in the same conversation as Cerebras and Blackstone’s data-center REIT as a public-market proxy for AI infrastructure build-out. The trade-off investors are accepting: a still-developing technology and a single-project-heavy revenue base, in exchange for a near-pure-play bet that hyperscalers will keep paying premium prices for 24/7 clean power.
