Shares that insiders have been unable to sell begin opening up again on Thursday, October 22, and this SpaceX lockup expiry is the biggest test yet of how much stock holders actually want to sell. Most reports say up to 1.3 billion shares become eligible, the largest single batch since the June 12 listing. The stock closed Wednesday at $159.31, up 7.8% after earnings, according to a Motley Fool column. Eligible to sell isn’t the same as will sell, and the record so far is more mixed than the headlines suggest.
What the SpaceX lockup is
Lockups are a standard feature of IPOs. Employees and early investors agree not to sell for a stretch, often 180 days, so the market isn’t flooded the day trading starts. Quartz reported in May that SpaceX chose a staggered design instead, letting most insiders sell in pieces well before the full period runs out, with release dates tied to earnings reports and calendar milestones. Elon Musk is the exception. His shares stay locked until June 12, 2027, according to a broker’s summary of the prospectus figures.
The design has a side effect, Quartz noted: it can widen the public float faster than a standard lockup would. It also breaks one giant sale date into many smaller ones, so the SpaceX lockup produces a string of events, each with its own round of headlines.
Our numbers come with a caveat. SpaceX’s registration statement is on the SEC’s site, but the lock-up section wasn’t in the portion of the filing we could read, so the share counts and dates here come from secondary reports. Those reports disagree. Most say up to 1.3 billion shares open Thursday, while one Motley Fool column puts it at 911.5 million, the figure from the August unlock. We’re using the larger number because more outlets report it, and we’d treat it as approximate.
What the first six unlocks did
Motley Fool’s table, republished by Longbridge, covers six earlier unlocks. The first came on August 6 and freed about 912 million shares. The stock rose about 6% that day. Later releases were mostly around 320 million shares, and the stock’s moves on those days ran from a 4% drop on August 20 to a 1% gain on October 9. By our arithmetic the six freed roughly 2.27 billion shares in all, and the SpaceX lockup record shows no consistent drop on release days. As of October 19 the stock was up about 27% from August 6, the same article said.
Before the first unlock, Yahoo Finance’s August preview collected a wide range of views. Morningstar’s Nicolas Owens expected most of the available shares to reach the market, since early holders have low cost bases. Mizuho’s Brett Linzey cautioned that eligibility doesn’t mean the whole batch gets sold, while Morgan Stanley’s Adam Jonas called the event a buying opportunity. The stock rose that day. Six data points don’t make a pattern, but the result cuts against the bearish case.
Why Thursday is different
Thursday’s batch is larger than August’s 912 million, the biggest before it. By our arithmetic it’s roughly 10% of SpaceX’s shares outstanding, based on the Motley Fool column’s $2.16 trillion market value at $159.31, which implies about 13.6 billion shares. A broker’s summary of the prospectus figures says the tradable share of the company rises from about 22% to about 32%, though that summary has internal inconsistencies, so treat the percentages loosely.
The timing also matters. The unlock lands right after a strong earnings report, and the stock already jumped on it. Buyers have just pushed the price higher, which gives anyone who wants to sell a better exit than a week ago, and it means the SpaceX lockup arrives with expectations raised. A flat day could read as a letdown even if nothing is wrong.
Index funds add another wrinkle. SpaceX joined the Nasdaq-100 in July, and the broker summary says JPMorgan estimated about $15.5 billion of index buying around the September rebalance. That estimate comes from a marketing page, so check it against the bank’s own research before leaning on it. As for what comes next, two reports put the next release of about 319 million shares on Monday, October 26. A third gave October 24, a Saturday, so we’re going with Monday.
What it means if you own SpaceX
How you own the stock shapes how much this matters. Direct holders feel price moves immediately. Index fund holders feel them in proportion to SpaceX’s weight in the fund. Neither group has to act because of a lockup date, and dates like this are public, so traders trade around them. JPMorgan’s Doug Anmuth noted heavy pre-positioning before the August unlock, per Yahoo.
Supply is only half of the price story. Demand matters, and so do interest rates. With the 10-year Treasury yield above 5%, as we reported, richly valued stocks face a higher bar. That’s general market logic, not a call on SpaceX.
Crowded exits aren’t unique to stocks. Private credit funds faced a similar rush for the door, as our Blue Owl redemptions story explains. Liquidity feels plentiful until many holders want out at once. When you read any SpaceX lockup headline, it helps to check how many shares that is compared with what already trades, and to remember that the headline figure is the most that could be sold, not what will be.
Signs to watch after Thursday
Watch Thursday’s trading volume against the roughly 95 million-share average Motley Fool cited, and look for insider sale filings, which show who actually sold. The October 26 tranche comes next, and December 8 is when the full 180-day period ends. This is general information, not financial advice, and none of it is a prediction.
Editor’s take
A lockup expiry is a calendar event, not a verdict. The first six showed the stock can absorb new supply when buyers show up, but Thursday’s batch is the largest test so far and it follows a big run-up. The better signal isn’t Thursday’s price. It’s how many insiders file to sell over the weeks after. Until those filings appear, treat the headline share count as the most that could come to market, not a forecast of what will.
