Kalshi and Polymarket traders price Musk trillionaire odds above 90% on SpaceX IPO hopes

Published May 29, 2026Updated 51d ago

Traders on Kalshi and Polymarket have priced above 90% probability that Elon Musk will become a trillionaire before 2027, driven by anticipation of a SpaceX IPO. Kalshi also shows 52% odds for a SpaceX-Tesla merger by May 2027, which would create a $3.4 trillion combined company, while separate Polymarket markets are pricing SpaceX at a $1.8 trillion valuation post-IPO and wagering on IPO timing. The surge in implied probability coincides with speculation about SpaceX's planned public debut under the ticker SPCX, though no specific IPO date has been disclosed. No open-interest, volume, or contract terms were disclosed for several of the markets, according to the Kalshi account's post on Friday, May 30.

Why this matters?

Kalshi now runs three correlated Musk-themed contracts without disclosed volume or open interest. Any institutional desk routing flow through Kalshi's terminal needs position-level transparency to distinguish liquid conviction from reflexive retail speculation before sizing merger or IPO bets.

The bigger picture

Kalshi and Polymarket are now running overlapping pre-IPO contracts on SpaceX valuation, merger odds, and Musk's personal net worth, joining the first-day pricing market as the third distinct SpaceX-linked vertical.
