SpaceX's 15-Date Lockup Ladder: Musk's 366-Day All-or-Nothing Bet

SpaceX's public debut raised roughly $75-86B (base offering vs. reported figure including greenshoe) at a $135 IPO price, yet locked up 95% of its ~13 billion shares — the most fragmented release schedule seen in a mega-cap IPO to date. Where Airbnb, DoorDash, and Snowflake shortened or staggered the standard 180-day lockup, SpaceX went further: 15 separate unlock dates spanning August 2026 through August 2027, tied to a mix of fixed-day milestones, earnings releases, and a price trigger (an extra 10% unlocks early only if the stock closes 30%+ above IPO price on 5 of 10 trading days pre-Q2 earnings). The structural logic: metering supply into the market in small tranches (7% here, 20% there) avoids the cliff effect that typically hits newly public stocks when insiders dump en masse at the 180-day mark. It also buys SpaceX political cover — no single date where a headline reads 'insiders cash out.' The real story is Musk's carve-out. His 6.4B shares (82%+ voting control) are locked for 366 days with no early-release conditions — the strictest tranche in the entire schedule. Analysts note his Tesla precedent (borrowing against shares rather than selling) as the likely playbook here too. The wildcard: on day 366, it's not a taper — it's a single-date unlock of the largest holder's entire position. Watch point: Nov 4, 2026, releases 1.3B shares (28% of the 180-day block), the single largest tranche before Musk's own unlock — the date to flag for share-price stress-testing.
