SpaceX Lock-Up Calendar: Every Date and the Comms Risk

SpaceX's insider lock-up ends in stages, not on one date. Up to 328.4 million shares became eligible on October 9, another tranche follows on October 24, up to about 1.3 billion unlock two full trading days after third-quarter results, the rest on December 8, and Elon Musk's shares stay locked until June 2027, according to the IPO prospectus as summarized by The Financial Sciences Company.

What is the SpaceX lock-up schedule?

The SpaceX lock-up schedule releases shares for employees and most pre-IPO holders in a first earnings tranche, five fixed-date tranches, a third-quarter tranche and a final release on December 8, 2026. The dates and share counts below come from SpaceX's June 11 prospectus, as summarized by The Financial Sciences Company on September 25, 2026, and share counts are approximate.

The Q3 tranche is the largest single release, roughly four times the October 9 tranche, according to InvestingLive's reading of the schedule.

How large was the SpaceX float at the IPO?

The SpaceX float at the IPO was small compared with the locked shares. CNN reported that SpaceX sold roughly 640 million shares, less than 5% of its total shares, and that the first unlock more than doubled the shares available to the public.

The offering raised more than the $75 billion reported at pricing. Reuters reported $75 billion from 555.56 million shares at $135 on June 11, and the Motley Fool reported another $10.7 billion when underwriters exercised their option, which brings the total near the $85.7 billion Quartz reported. Earlier EPR pages use the $75 billion pricing figure. See the SpaceX PR strategy page for the pricing and disclosure details.

How did the stock handle the first unlock?

The stock handled the first unlock better than many analysts had warned. CNN reported that SpaceX shares rose more than 6% on August 6, the day 911.5 million shares unlocked, after a 13.6% drop the day before, according to Yahoo Finance, that followed the first earnings report.

Axios had reported on July 17 that SpaceX closed at $131.11, below the $135 offer price, with the first lock-up approaching. The path since then is a reminder that supply schedules do not set the price by themselves. For the earnings details, see the Elon Musk PR strategy guide.

What does each unlock window mean for SpaceX's communications?

Each unlock window raises the cost of an unreviewed statement, because shares that were not tradable a week earlier can now be sold. The table is EPR's analysis of the communications risk in each window and is not a prediction.

SpaceX's Form 8-K already names the investor relations page and the @SpaceX account on X as the places where it announces material news, and it does not name Musk's personal account. The risk of a post from an undesignated account is covered in the DraftKings Regulation FD case.

What should other newly public companies plan around lock-ups?

Newly public companies should lay the lock-up calendar over their communications calendar before the IPO prices. Five steps cover the work.

1. List every release date and size in one calendar, and mark the earnings dates that trigger releases.
2. Require legal and investor relations pre-clearance for executive posts in the days around each release.
3. Publish the earnings transcript and fact sheet in HTML so the company's own wording is the first source engines and analysts read.
4. Prepare the capital-spending or growth-investment explanation before the call, since a revenue beat did not protect SpaceX's stock after its first report.
5. Keep the same figures and phrasing across the filing, the call and the IR page. See the earnings call communications playbook and IPO communications.

Why it works. A release date increases the number of holders who can act on a statement, so a pre-clearance step and consistent wording reduce the chance that one post becomes a trading signal. This is EPR guidance drawn from the Regulation FD cases above, not research on lock-up behavior.
