By 2030, there could be the same kind of financial interest in nuclear fusion as there is in AI right now, investor Matt Trevithick of Leitmotif said at a conference on Wednesday.

Why it matters: The fusion sector will need billions of dollars more than what VCs can provide to reach commercialization.

Zoom in: Trevithick, who has backed seven fusion startups over close to 20 years, is looking to the public markets to provide the needed capital to ramp up fusion.

"We have to get very good at telling the story to the public. It's going to take at least two or three years to get that going," said Trevithick at the FusionXInvest conference at the Computer History Museum in Mountain View, Calif.

Acquisitions aren't a strong exit strategy for fusion startups, and investors can't fund fusion firms indefinitely, Trevithick said. "The race is on to get some exits here."

The public markets will be important for fusion companies, but there will be some setbacks and some faceplants. "It's just how markets work," said Eric Helfgott, a principal at Lowercarbon Capital.

Investors need to help set expectations in a way where those setbacks don't drain capital from private and public sources, noted Helfgott, whose firm has made eight fusion investments.

Catch up quick: Nuclear fusion, and its promise for near-limitless zero-emissions electricity, has been in development for a century and is not a commercial technology.

Over the past several years, venture interest has grown in the sector, and companies like Commonwealth Fusion Systems, Helion, and Pacific Fusion have raised major rounds.

By the numbers: There has been close to $13 billion in private and public funding for fusion companies over the years, according to FusionX, which put on the conference.

"The biggest risk to fusion is financing," said Trevithick, who says the sector will need on the order of $50 billion to $60 billion to become commercial.

Zoom out: Fusion IPOs might sound speculative, but companies that have a clear road map for scientific milestones, and partners like energy firms, could make the case to public investors.

Commonwealth Fusion Systems, which has raised more than $2 billion, mostly from private investors, will need billions more to fund ARC, its commercial fusion machine.

"If we start getting the first electrons flowing on the grid in the 2030s, then that's going to really get the attention of public markets and lots more investors," said Phil Larochelle, a partner with Breakthrough Energy Ventures, which has made five fusion investments.

"If you start investing now, you have the opportunity of some really good exits, potentially on the 10-year or less time," said Larochelle to a room of investors.

Bottom line: Fusion investing is hot, but it's still a moonshot pre-commercial technology.
