SpaceX’s SPCX lockup does not end all at once; it unlocks in stages. The standard insider lockup appears to finish around 180 days after the June 12, 2026 IPO, which puts the main full release in mid-December 2026 , while Elon Musk and some major holders remain locked until about June 12, 2027.

What unlocks when

  • 70, 90, 105, 120, and 135 days after IPO: small staged releases of about 7% each.
  • After the first earnings report: investors can sell up to 20%, with a possible extra 10% if the stock trades strongly before earnings.
  • Around mid-December 2026: the usual 180-day lockup ends for the remaining standard insider shares.
  • Around June 2027: Musk and certain significant holders are still locked beyond the standard period.

Practical read

For retail traders, the important date is mid-December 2026 for the main lockup expiration, but the float can still expand much earlier because of the staggered releases tied to trading days and earnings. That means supply pressure may show up in waves, not just on one single date.

Quick caveat

Some market articles simplify this as a “180-day lockup,” but SPCX actually uses a tiered release schedule, so the exact unlock impact depends on which holder group you mean.
