Pacific Fusion risks losing buyers
Pacific Fusion
The real risk is not just technical delay, it is losing the first wave of buyers while rivals lock up scarce grid sites, interconnection capacity, and customer attention. Helion and Commonwealth Fusion Systems already have named offtake partners, which means large power buyers are not waiting for fusion to be proven before reserving future supply. Pacific Fusion, by contrast, is still earlier in customer formation even as it targets a similar commercial window.

Helion has already signed a power agreement with Microsoft for a plant targeted to come online in 2028 at 50 MW or greater after ramp up. Its model is straightforward, build and own the plant, then sell electricity under long contracts to hyperscalers and industrial users.

CFS has gone further on customer signaling, with Google agreeing to buy 200 MW from its first ARC plant in Virginia and Eni signing a power offtake agreement worth more than $1 billion. That gives CFS not just validation, but a real queue of anchor demand around an early 2030s launch.
-
These early deals matter because power customers do not buy fusion as a science project. They buy reserved future megawatts, grid connection plans, and decarbonized baseload supply. Once a hyperscaler or utility has contracted for one platform, the next contract often goes to a different site or a later procurement cycle.
The likely next phase is a shift from physics milestones to customer land grabs. Fusion companies that pair credible engineering progress with signed power buyers will shape where the first commercial plants get built, and late entrants will have to win business after the easiest counterparties and sites have already been spoken for.
