Buried deep in the SpaceX S-1 (IPO) filing is a very unique lock-up release timeline that early employees can use to sell shares.
Instead of the standard 180-day lock-up period from most companies, SpaceX shares from early shareholders will release gradually over the following checkpoints:
· IPO JUNE 12, 2026 · NASDAQ
SpaceX Lock-Up Release Schedule

366-Day Lock-Up holders: The S-1 specifies that only __% of 366-day lock-up shares qualify for the early release windows above. The remaining shares in that bucket are locked until June 13, 2027 (366 days post-offering). The exact percentage was not disclosed in the draft S-1 — confirm in the final prospectus before advising clients with 366-day restricted shares.

After 180-days, all shares will be released.
The only exception is for certain early shareholders who may be subject to a separate 366-day release program (not outlined yet in S-1).
