Key Takeaways
- • Prime Movers Lab closed its second early-stage venture fund at $245 million, attracting capital from prominent hedge fund managers Bill Ackman (Pershing Square Capital Management) and Dmitry Balyasny (Balyasny Asset Management), alongside the University of Wyoming, the Lerner Family Office, and co-founder Joe Lonsdale.
- • The firm's early-stage portfolio company Momentus is merging with SPAC Stable Road Acquisition Corp. to go public, with founder Dakin Sloss indicating three additional portfolio companies have SPAC mergers "announced soon."
- • Sloss argued SPACs offer superior shareholder economics versus traditional IPOs because companies can present forward-looking financial statements during valuation negotiations—a privilege unavailable in public market offerings but common in private funding rounds.
- • Prime Movers Lab Fund II represents continued investor confidence from the same LP base that supported its predecessor $100 million Fund I, signaling sustained institutional appetite for early-stage deep technology and scientific breakthrough investments.
Summary
Prime Movers Lab, a Wyoming-based venture capital firm specializing in scientific breakthrough startups, has successfully closed its second institutional fund at $245 million. The raise demonstrates institutional investor conviction in the firm's strategy and underscores growing capital flows into early-stage deep technology companies. The fund attracted a marquee investor roster including hedge fund titans Bill Ackman of Pershing Square Capital Management and Dmitry Balyasny of Balyasny Asset Management, alongside the University of Wyoming, the Lerner Family Office, and Joe Lonsdale, co-founder of Palantir Technologies and OpenGov. All participants had previously committed capital to Prime Movers Lab Fund I, which raised $100 million.
The announcement arrives as Prime Movers Lab prepares to execute a meaningful exit from its portfolio. The firm was an early-stage backer of Momentus, a commercial space business that is merging with special purpose acquisition company Stable Road Acquisition Corp. to achieve public market listing. More significantly, founder and Stanford graduate Dakin Sloss disclosed that three additional portfolio companies have SPAC merger deals pending announcement, positioning the firm to capitalize on the blank-check company vehicle for liquidity events.
Sloss articulated a substantive thesis on SPAC superiority relative to traditional IPO structures. According to Sloss, SPACs enable portfolio companies to present forward-looking financial statements during valuation negotiations—a mechanism permitted in private funding markets but prohibited under standard IPO regulatory frameworks. This disclosure capacity theoretically generates superior shareholder returns by allowing more accurate valuation calibration. The commentary reflects broader institutional debate around SPAC economics and the comparative merits of alternative public market entry strategies for growth-stage companies.
