Billions Flow To Nuclear, Grid AI And Battery Storage

Capital keeps racing into nuclear power, grid software, and energy storage as investors chase the electricity buildout behind artificial intelligence.

At a glance: Fresh figures from Crunchbase show global startup investment reaching a record 510 billion dollars in the first half of 2026, and the newest wave of deals confirms that the momentum has not cooled heading into August. Money is concentrating around three linked themes, the electricity needed to run artificial intelligence, the hardware that generates and stores that electricity, and defense technology, where startup funding has climbed to an all time record led by names such as Anduril. Investors are writing larger checks at higher valuations, and billion dollar private rounds that once looked exceptional now arrive several at a time. Energy, nuclear power, batteries, and industrial automation dominate the mix, while exits are reopening through confidential public filings and strategic acquisitions. The result is a market where capital is abundant, selective, and pointed squarely at the physical infrastructure of the next computing cycle.

Technology advance: Valar Atomics, the El Segundo, California nuclear startup, said on August 3 that it had raised a 1 billion dollar Series B led by Sequoia Capital, alongside a 200 million dollar credit facility, tripling its valuation to 6 billion dollars post money. Sequoia partner Shaun Maguire led the investment, with participation from Atreides Management, Point72, and Snowpoint Ventures. The company plans to mass produce small modular nuclear reactors designed to sit next to data centers and supply firm, round the clock power directly to artificial intelligence computing clusters, bypassing congested grids. Valar intends to use the proceeds to move from prototype toward series production of its reactor design and to fund early test deployments. The round is one of the largest ever for an early stage nuclear developer and signals investor conviction that new build atomic energy, not just solar and wind, will underpin the AI power buildout.

Partnerships: KKR and TotalEnergies unveiled a European renewables partnership in which KKR will acquire a 50 percent stake in a portfolio of developed onshore solar and wind assets held by the French energy major, a portfolio valued at roughly 1.8 billion euros. The tie up, disclosed in early August, lets TotalEnergies recycle capital from operating assets while retaining a half interest and continuing to manage the sites, and it channels KKR insurance backed capital into contracted clean power across several European markets. In the same set of announcements, TotalEnergies agreed to acquire Shell's European onshore renewables business, deepening its developed asset base on the continent. Together the moves illustrate how large infrastructure investors and oil majors are pairing off, sharing ownership of built out wind and solar rather than competing to develop it, to spread risk and free up cash for new projects.

Acquisitions/expansions: Schneider Electric agreed to acquire AiDASH, the Palo Alto based grid resilience and utility asset monitoring company, for 350 million dollars in cash, in one of the largest climate adaptation exits on record. AiDASH uses satellite imagery and artificial intelligence to help utilities monitor vegetation, wildfire risk, and infrastructure health across their networks, and it had previously raised about 91.5 million dollars from backers including G2 Venture Partners, Lightrock, National Grid Partners, and Shell Ventures. Schneider, the French electrical equipment giant, will fold the technology into its digital grid software portfolio as utilities spend heavily to harden aging networks against extreme weather and surging electricity demand. The deal gives AiDASH investors a clean strategic exit and underscores how incumbent hardware vendors are buying AI driven software to move up the value chain and lock in recurring utility revenue.

Regulatory/policy: Westinghouse Electric, the nuclear technology company jointly owned by Brookfield Asset Management and Canada's Cameco, confidentially submitted a draft registration statement to the United States Securities and Exchange Commission for a proposed initial public offering. Cameco disclosed the filing in early August, noting that the number of shares and the price range have not yet been determined and that the offering is expected to proceed after the SEC completes its review, subject to market conditions. The confidential S-1 route lets the company test investor appetite and work through regulatory scrutiny before committing to public terms. A Westinghouse listing would be one of the highest profile energy market debuts of the year and a direct beneficiary of policy momentum behind nuclear power, as governments extend reactor licenses and back new build to meet data center and electrification demand.

Finance/business: Base Power, the Austin, Texas home battery storage company, closed a 1 billion dollar Series D that lifted its valuation to about 13 billion dollars post money, drawing a long roster of investors including Andreessen Horowitz, Lightspeed, Coatue, Thrive Capital, Valor Equity Partners, and JPMorgan Chase. The financing ranks among the largest private rounds of the week and reflects surging demand for distributed storage that can stabilize strained grids and lower household bills. Capital is also pooling at the fund level, with Energy Capital Partners closing its sixth flagship vehicle at 8.1 billion dollars to pursue power and infrastructure deals. In mobility, Moove raised a 250 million dollar Series C led by Mubadala at a 2.1 billion dollar valuation to expand vehicle financing for autonomous and ride hailing fleets. The breadth of these commitments shows investors funding both the assets and the platforms of the energy transition.
