What is an IPO lockup expiry?
An IPO lockup expiry is the date on which pre-IPO shareholders — typically employees, early investors, and founders — are first permitted to sell their shares after a standard 180-day restriction period following the IPO. The lockup window blocks insider selling pressure in the first months after listing.
When does the SpaceX (SPCX) lockup expire?
SpaceX (Nasdaq: SPCX) IPO'd on June 12, 2026. The standard 180-day lockup puts the expiry on or around December 9, 2026. Employees and pre-IPO investors will be able to sell into the public market at or shortly after that date.
What happens to a stock price after lockup expiry?
Historically, stocks experience higher volatility and downward pressure in the days and weeks following lockup expiry. The magnitude depends on the percent of float unlocked, recent stock performance, and broader market conditions. The period around day 175–185 post-IPO is the most concentrated insider-sale window.
How can investors buy pre-IPO shares before the lockup expires?
Accredited investors can access pre-IPO and unvested shares locked up at recently-public companies through secondary market platforms like Hiive and Forge Global. Retail investors typically wait for the IPO listing on a brokerage account.
How does TechStackIPO source lockup expiry dates?
Lockup dates on TechStackIPO come from three sources: (1) standard 180-day calculation from each company's IPO date, (2) SEC EDGAR Form 144 filings (Notice of Proposed Sale of Securities), and (3) direct company disclosures in 8-K filings.
Disclaimer:
Lockup expiry dates represent the date on which contractual insider-sale restrictions lapse under the standard 180-day window enforced by underwriters. Early lockup releases, modified lockups (employee/insider classes), and company-specific extensions are documented in the relevant S-1 forms on SEC EDGAR. The presence of a Form 144 filing in the days before lockup expiry is a directional signal of insider-sale intent — not a confirmation of executed trade.
