Remains to be seen.

Helion would have to ship something that gives positive net energy first.

Sure, they have prototypes, but we don't know how well they are currently performing

Agree, that will be the proof. But tokomaks have yet to do the same despite decades of investment.

We know that helion is able to recover 95% of the energy of every pulse. And they've measured the scaling laws. There doesn't seem to be anything that will prevent net positive energy in the reactor they're building right now.
