328 million more SpaceX shares unlock Monday, days after a 1.3 billion share release

SpaceX holders get a second wave of supply in less than a week. About 1.31 billion shares became eligible to sell two full trading days after the company’s third-quarter report, and another 328.4 million follow on Monday, Oct. 26. The prospectus date is Saturday, Oct. 24, so Monday is the first trading day those shares can change hands.

The timing is unusual: the releases land right after a quarter that beat expectations. Here is what changed, how the stock has handled earlier unlocks, and what to watch when the market opens.

The quarter that came first

SpaceX reported its third quarter on Oct. 20 after the close. Revenue was about $14.58 billion against roughly $12.97 billion expected, and earnings per share were $0.35 against about $0.14 expected. The stock rose about 8% to 9% in after-hours trading.

A strong report changes the math for holders whose shares just unlocked. Some may be happier to hold; others may see a higher price as a better moment to sell. The table below shows each release and SPCX’s move on its first trading day, including the third-quarter tranche once it has traded.

How earlier releases played out

The pattern so far has been more about the days around a release than the release day itself. After the second-quarter report on Aug. 4 the stock fell about 14%, then rose about 6% on Aug. 6 when 911.5 million shares unlocked. Of the five fixed-date 7% tranches, the trading day before was down four times; the release days ranged from a 4% drop to a 1% gain.

Volume tells a similar story. In our data, only the Aug. 6 release drew several times normal volume; the later 7% tranches traded between roughly normal and 1.6 times normal.

What to watch on Monday

Volume is the clearest signal. SPCX trades about 68 million shares on a typical day, so the 328.4 million share tranche is roughly five days of normal trading. A session with several times normal volume and a falling price would suggest real selling; normal volume would suggest most holders are waiting.

Filings come next. Directors and officers must report sales on SEC Form 4 within two business days, so sales on Monday would show up by Wednesday. The largest recent insider trades are below.

The chart below tracks SPCX's daily closing price from June 12, 2026 to Oct. 23, 2026. Over that stretch it is down 8.4%, from $160.95 to $147.49, with a high of $201.80 on June 16, 2026 and a low of $108.27 on Aug. 5, 2026. Each red circle marks a week in which company insiders sold shares on the open market (1 week in this period; bigger circles mean more money). There are no green diamonds: no insider bought on the open market in this window.

What comes after this week

After Monday, the rest of the standard lock-up ends on Dec. 8, 2026. Elon Musk’s own block, about 6.4 billion shares, stays locked until June 2027, and about 352 million more shares unlock two trading days after each future quarterly report.

What would change the picture for SPCX

These are the specific events and levels to watch. None of them is a prediction.

• An open-market purchase by an insider at Space Exploration Technologies Corp. There has been none in 90 days; Form 4 filings would show one within two business days of the trade.
• Price levels: a close above $201.8 would be a new 52-week high, 36.8% above the latest close of $147.49; a close below $108.27 would be a new 52-week low, 26.6% below it.
• New shares: dilution risk is moderate now. A new shelf registration (S-3) or a prospectus supplement (424B) for an offering would raise it.

How SPCX compares with its peers

Over the past month SPCX ranks 1 of 2 in this group (-0.4%); the best was SPCX (-0.4%) and the weakest TSLA (-1.5%).

A dash in the P/E column means the company lost money over the last 12 months, so it has no P/E.
