- Total Outstanding Shares: Approximately 13.1 billion to 13.2 billion shares. This figure is derived from the company's stated IPO valuation of roughly
$1.77 to $1.78 trillion at its debut price.
- Shares Available to the Public (Float): $SpaceX(SPCX)$ offered 555.6 million shares to investors during the IPO.
- Restricted Shares: The vast majority of the 13+ billion outstanding shares are currently held by insiders, pre-IPO investors, and founder Elon Musk (who owns an
estimated 40% to 50% of the company). Many of these shares are subject to "lock-up" periods and will gradually become available for public trading over the coming months.
Lock up Periods Ends
- Unlike a traditional IPO with a single 180-day cliff, SpaceX structured its lock-up period to be highly staggered and front-loaded to gradually increase
the number of shares available to the public.
- While the standard 180-day lock-up fully expires on December 8, 2026, millions of shares will begin trickling into the market months before then, and major
insiders are locked out for much longer.
Staggered Release Schedule
Here is the exact timeline for when different groups can sell their shares, according to the company's S-1 filing:
First Major Unlock (Post-Q2 Earnings)
Late July / August 2026
Up to 20% of eligible restricted shares held by regular shareholders (like employees and early backers) become available after the Q2 earnings call. An additional
10% unlocks if the stock trades at least 30% above the $135 IPO price for 5 out of 10 consecutive trading days.
Time-Based Tranches
August – October 2026
7% of shares unlock at five rolling post-IPO intervals: Days 70, 90, 105, 120, and 135.
Q3 Earnings Unlock
Late October / November 2026
Another 28% of the initial restricted block unlocks after the Q3 earnings release.
180-Day Full Expiry
December 8, 2026
The standard lock-up ends. All remaining shares held by regular shareholders become fully eligible for sale.
Institutional Unlocks
March – August 2027
Major pre-IPO institutional backers (such as Google and Valor Equity) have their shares released in six staged tranches.
