Major financial publications could not agree this month on when SpaceX would unlock 319 million additional shares. Three different dates were published. At Wednesday’s share price, the unlock is worth roughly $46 billion. That is a large enough number that shareholders might want a precise date. But nobody seemed to know.
A matter of interpretation
The prospectus does not actually promise exactly 319 million shares. It says ‘up to 319 million shares’, and that number excludes shares held by affiliates. So the practical number could be higher. For now, most observers use the 319 million figure.
The earliest guess, August 12, is easy to rule out. The current share count at SpaceX stands at 7.7 billion, and that has not changed in three days. Major financial websites agree the float did not increase by 319 million on August 12.
The other guesses were August 20 and August 21. To sort this out, the prospectus date matters. SpaceX priced its IPO on the evening of June 11, and Nasdaq trading opened the next morning. The cover of the prospectus says ‘Prospectus Dated June 11, 2026.’ Every lockup trigger counts from that date. The release table puts the 319 million share tranche on the 70th day after the date of this prospectus.
June 11 plus 70 days is August 20. The same June 11 anchor also produces confirmed dates for later unlocks: September 9, October 24, and December 8. Those dates appear in the filing, so June 11 appears to be the right starting point.
Some outlets repeated the wrong date
The August 21 camp came close. The August 12 camp was not close. TradingKey reblogged the error anyway, saying approximately 319 million shares could be released as soon as August 12. Asbury Capital, an advisory firm linked to Steven Engle, also told clients the unlock would happen around August 12.
Peter Singlehurst, who leads a private companies team at Baillie Gifford, told Bloomberg that nothing like this has been seen before. He pointed to the scale and the phased lockup structure. His point seems fair. The unlock is unprecedented in size. The timing, though, was not a secret.
What happens next
The closest valid date based on the filing is August 20. That places the unlock next week. Market participants should probably rely on the prospectus rather than secondary sources. The confusion shows how easily a minor counting error can spread when a large event attracts attention.
SpaceX’s lockup schedule remains unusual because it releases shares in phases. That may explain some of the uncertainty. But the underlying math is not complicated. The anchor date is clear. The printed schedule lines up. None of that helped when several outlets picked different dates and amplified the wrong one.
