Climate tech IPOs surge while AI Hype Index tracks industry fiction

Solar and battery company Solv Energy went public in February at a $6 billion valuation, followed by small modular nuclear reactor builder X-energy at $11.5 billion, and geothermal firm Fervo Energy reaching a market cap of about $12.4 billion. All three IPOs succeeded as data center growth drives unprecedented electricity demand, signaling a fundamental shift in grid investment. The boom highlights how climate tech is moving from experimental to essential infrastructure for AI's energy hunger.

On the AI front, MIT Technology Review introduced its AI Hype Index to help separate reality from fiction, covering everything from billionaire road trips to fabricated quotes and excessive sci-fi comparisons. Elsewhere, Illinois passed what could become America's strongest AI safety law requiring third-party audits, a Google engineer was charged with insider trading after using internal data to win $1.2 million on Polymarket, and ByteDance is developing custom CPUs due to severe AI chip supply shortages. Amazon, Google, Meta, and Microsoft also backed a clean energy initiative for data centers with up to $5 million per project.
