The claim, plainly

Helion Energy's Trenta fusion machine exceeded 100 million degrees Celsius, making Helion the first private company to reach that temperature.

a quote alone can be ambiguous, so this restates it with the references and context of the conversation around it resolved. AI-written; the tape below the player is the source.

Assessment

Press releases, news reports (such as World Nuclear News, EE Times, and EDN in 2021), and presentations at scientific conferences (including the 2021 IEEE Pulsed Power Conference & Symposium on Fusion Engineering) confirm that Helion's Trenta prototype exceeded 100 million degrees Celsius, and that Helion was the first private fusion company to reach this milestone.

Helion Energy announced in June 2021 that its Trenta generator prototype exceeded 100 million degrees Celsius, making it the first private fusion company to achieve this threshold.
Multiple independent news reports (World Nuclear News, EE Times, EDN) documented and corroborated the milestone in mid-2021.
