SpaceX’s first post-IPO share lockup window opened Thursday, Aug. 6, making up to about 911.5 million shares eligible for sale and more than doubling the stock’s publicly available float.
CNN Business reported the unlock as the first in a staggered series lasting into 2027, arriving a day after SPCX closed at $108.27 following an almost 14% drop tied to Tuesday’s earnings and the approaching float expansion. CNBC had previously mapped the calendar: after SpaceX set Aug. 4 for its first public quarterly report, the prospectus clock pointed to the second full trading day afterward for the initial 20% early-release tranche.

What unlocked
Coverage citing the IPO prospectus describes an unusual tiered schedule rather than a single 180-day cliff. Early release-eligible holders may sell up to 20% of eligible shares on Aug. 6. An extra 10% bonus release tied to trading at least 30% above the $135 IPO price did not trigger, The Motley Fool reported.
Elon Musk’s holdings remain locked until one year after the June 12 listing, CNN and Motley Fool coverage of the prospectus terms both note. Later Class A unlocks continue through the fall and into December, with additional executive windows in 2027.
Market setup
SpaceX listed June 12 in what outlets call the largest IPO on record, but with less than 5% of shares freely trading at debut. The Motley Fool estimated Thursday’s eligible block at roughly three times the prior public float of under 280 million shares, framing potential selling pressure in the tens of billions of dollars depending on price and how many holders actually sell.
CNN also flagged an index angle: a larger free float can raise SpaceX’s Nasdaq-100 weight at the September rebalance, though that still depends on where the stock trades.
Not a guaranteed dump
A steep sell-off is not automatic. Motley Fool analysis ahead of the open argued insiders could wait for later unlock dates or hold for longer-term gains, even while warning that a sudden jump in supply can still pressure price. Asianet Newsable, citing early Thursday trading, said SPCX was up nearly 3% as some investors looked past the unlock, while analysts still expected elevated volatility as the float expands.
Wednesday’s session had already reset the tape: revenue jumped about 92% in the first public quarter, but investors focused on heavy AI capital spending, helping send the stock to levels CNN described as an all-time closing low heading into unlock day.
