On May 12, 2026, Ron Baron, founder and CEO of Baron Capital, said in a televised interview that SpaceX will become the world's largest company. His remarks coincide with market speculation about a mid-2026 SpaceX IPO and follow rapid asset gains at Baron Capital linked to early investments in Elon Musk ventures.
Baron's Forecast and IPO Valuation Concerns
Baron publicly forecast that SpaceX could reach valuations between $10 trillion and $30 trillion over the long term, according to secondary reports citing his statements. Baron Capital’s assets under management grew by $14 billion over six months, gains attributed to concentrated bets on Musk-related companies. Reports indicate the firm is heavily exposed to SpaceX and is seeking about $1 billion more in capital for that exposure.
Market speculation places the IPO valuation between $1.75 trillion and $2.0 trillion, with a capital raise near $75 billion and a listing expected in mid-2026. The valuation debate centers on SpaceX’s potential markets—satellite internet (Starlink), launch services, and space infrastructure—and the speed at which these businesses must scale to justify such figures.
Nasdaq approved a 2026 rule allowing new large public companies to join the Nasdaq-100 index after about 15 days, a significant acceleration from previous requirements. Earlier reports indicate SpaceX made early inclusion in the Nasdaq-100 a condition for its Nasdaq listing, a move that could boost passive fund inflows.
On May 6, 2026, the American Federation of Teachers (AFT) sent a letter to the SEC urging scrutiny of the planned offering. The union flagged a valuation mismatch with SpaceX’s current financials, raised concerns about leadership and accounting practices, and warned that index-rule changes could force exposure for roughly $3 trillion in member retirement assets. The SEC declined to comment, and SpaceX did not respond to requests for comment. No official SEC registration statement, prospectus, or company announcement has been filed or publicly disclosed.
The combination of multi-trillion valuation claims, a very large proposed capital raise, the union’s regulatory warning, and the absence of official filings heightens governance and disclosure risks for investors considering exposure to the offering.
