Private fusion startups have raised significant capital, with Commonwealth Fusion Systems and Helion at the forefront. TAE Technologies plans a merger with Trump Media & Technology Group.
There are companies trying to make a machine that can turn the sun's energy into power. One company called Commonwealth Fusion Systems is working on making a big machine that could start producing electricity soon. Another company, Helion, wants to have their machine produce power by 2028 and they're going to sell some of it to Microsoft.
Analysis
{"#Commonwealth_Fusion_Systems":"- CFS raised $1.8 billion in a Series B round in 2021, bringing its total capital raised to $3.94 billion. The company aims to have Sparc operational by late 2026 or early 2027.\n- Sparc is a tokamak design with high-temperature superconducting magnets designed in collaboration with MIT. It's expected to produce power at commercially relevant levels and reach scientific breakeven in 2027.\n- Google has agreed to buy half of the output from Arc, its commercial power plant that will generate 400 megawatts of electricity.","#Helion":"- Helion plans to produce electricity by 2028 with Microsoft as its first customer. The company raised $465 million in a Series G round valued at $15.5 billion.\n- Helion uses a field-reversed configuration reactor, where magnets surround the reaction chamber shaped like an hourglass. Plasma is shot toward each end and induced to collide for fusion.\n- TAE Technologies merged with Trump Media & Technology Group, valued at $6 billion, with Michl Binderbauer as co-CEO.","#TAE_Technologies":"- Founded in 1998, TAE Technologies spun out of UC Irvine. It uses a field-reversed configuration reactor and bombards plasma with particle beams to stabilize it.\n- The company raised $150 million from existing investors including Google, Chevron, and New Enterprise in June 2025.\n- In December 2025, TAE announced plans for a merger with Trump Media & Technology Group valued at $6 billion."}
Key points
- Commonwealth Fusion Systems has raised $3.94 billion
- Helion aims to produce electricity by 2028
- TAE Technologies is merging with Trump Media & Technology Group
If these companies can build and operate their fusion reactors successfully, they could change the way we generate energy and make a lot of money doing so.
There are risks involved in building this kind of technology. If anything goes wrong with the machines or if investors lose interest, it could all be for nothing.
