Cracks Are Starting to Form on Fusion Energy’s Funding Boom

Fusion startups raised $1.6 billion over the past year, but the industry is increasingly split over when to go public and how to build revenue.

TAE Technologies and General Fusion are pursuing public listings that could bring in hundreds of millions of dollars.

Critics warn that listing before scientific breakeven could backfire if reactor progress lags and public-market expectations rise too fast.

There is also debate over whether companies should launch side businesses, such as nuclear medicine or power electronics, before proving their core reactors.

The outcome could shape investor confidence, listing standards, and the pace of commercialization across fusion energy.
