Why Google Just Bet $468M on Nuclear Fusion (And Why Microsoft Did Too)
Google backed fusion startup Proxima Fusion with $468M. Here's why Big Tech is racing toward fusion power to solve AI's growing electricity problem.
Why Google Just Bet $468M on Nuclear Fusion (And Why Microsoft Did Too)
Google just put real money behind one of the hardest engineering problems humanity has ever attempted. On July 7, 2026, the company backed German fusion startup Proxima Fusion in a €411 million (about $468 million) funding round — the largest private fusion investment in Europe's history. It's not Google's first fusion bet, and it won't be the last from Big Tech. Microsoft, Amazon, and OpenAI's Sam Altman have all made similar moves in the past two years. The reason is simple: AI is eating electricity faster than the grid can supply it, and fusion promises something the industry hasn't had in a century — a genuinely new source of clean, dense power. Here's what actually happened, what fusion power really is, and why it's suddenly a boardroom priority instead of a physics-department curiosity. What Google Actually Invested In Proxima Fusion is a three-year-old startup spun out of Germany's Max Planck Institute for Plasma Physics. The €411 million round w…
