Power Sector Floods Wall Street With $12.6B in IPOs Fueled by Data Center Demand

The first half of 2025 has produced a historic wave of energy IPOs, with companies in the sector raising $12.6 billion — the highest half-year figure on record and the largest since the dotcom bubble's peak in late 1999. The surge is being driven almost entirely by investor appetite for exposure to AI infrastructure, specifically the enormous amounts of electricity required to run the data centers that underpin modern artificial intelligence systems. A typical AI-focused data center consumes around 876,000 megawatt hours per year, roughly equivalent to the annual household electricity usage of a city the size of Glasgow or Salt Lake City. US electricity demand is projected to climb 39 percent between 2026 and 2035, with data centers accounting for a significant share of that growth.

Investors who rode the wave of AI chip stocks like Nvidia to extraordinary gains are now pivoting toward so-called 'picks and shovels' plays — the infrastructure companies expected to make the AI revolution physically possible. RBC clean energy analyst Chris Dendrinos described the shift succinctly: 'Investors started by buying AI-linked names like Nvidia. Then they said, hold on, every chip needs energy to power it.' That realization has opened the floodgates for energy companies across the spectrum, from gas engine manufacturers to next-generation geothermal developers, to access public capital at a scale previously unseen in the sector.

Among the notable listings, Forgent Power Solutions — which makes electrical distribution equipment for data centers — raised $1.7 billion in February. German gas engine manufacturer Innio completed a nearly $2.8 billion flotation in June. Geothermal startup Fervo raised approximately $2.2 billion in May, with plans to spend $1.2 billion developing its Utah power station over the next twelve months. CEO Tim Latimer told the Financial Times that public markets would help the company 'accelerate' its growth trajectory far beyond what private financing alone could achieve.

The IPO window has also opened for more speculative ventures, including companies working on small modular nuclear reactors and geothermal projects that remain in early pilot stages. Julien Dumoulin-Smith, a Jefferies research analyst covering power and clean energy, noted that 'speculative projects are being funded and underwritten' on public markets in a way that was previously reserved for venture capital and private equity. Exchange-traded fund provider GMO this week launched a dedicated power infrastructure ETF to capture returns from electricity generation, grid expansion, and electrification infrastructure, while nuclear energy group Standard Nuclear is expected to go public later in July.

Despite the fundraising momentum, performance data paints a more cautious picture. Nearly two-thirds of energy companies that went public this year and last are now trading below their IPO offer prices — compared with less than 40 percent of IPOs across all sectors. X-energy, backed by Amazon and focused on small modular reactors, is down 33 percent from its April debut. ERock, a gas generator maker, has shed 42 percent since its June listing, while data center energy company Fermi has lost 68 percent of its value since going public in September. Analysts and fund managers are warning that some investors are treating these IPOs as short-term trades, buying at flotation and quickly rolling proceeds into the next listing.
