Eligible Was Not Sold
SpaceX’s first major post-IPO lock-up release offered a useful test of how these events actually behave. Ahead of the 6 August release, 3 claims were on the table: the conditional 455.8 million-share tranche would remain locked, eligibility to sell would not necessarily mean actual selling, and an expanding free float could create additional passive demand alongside new supply. The conditional tranche did fail its price test, leaving 911.5 million shares eligible for release. SpaceX’s free float then jumped from roughly 4.9% to 11.8%. But instead of collapsing under the new supply, the stock rose 6.1% on release day and closed at $133.11 the following session, up another 15.83%. Two of the 3 predictions held. The third was never actually tested. The bigger lesson is that a lock-up expiry is more complicated than “more shares = more selling.” Eligibility, actual selling, float mechanics, and market demand are separate forces, and the SpaceX release showed why that distinction matters.
