When does the SPCX lockup expire?
The full SpaceX unlock calendar ⏳
SpaceX's lockup does not expire all at once. It releases in stages from the June 12, 2026 IPO, and the standard 180-day lockup expires on Wed, December 9, 2026. Between now and then, smaller tranches free up at roughly 70, 90, 105, 120 and 135 days, with the two largest slices tied to the first and third quarter earnings reports. Elon Musk and select major holders sit under a separate ~366-day lockup that runs until about Sun, June 13, 2027.
Dates are calculated from the June 12, 2026 IPO date using the day counts in SpaceX's reported lockup terms. Tranche sizes are approximate and subject to the prospectus, and the two earnings-linked unlocks move with the actual reporting dates. Editorial commentary, not investment advice.
Every SPCX lockup expiration date
SPCX lists on the Nasdaq at a $135 IPO price with a public float of only about 4.3%. Everything else stays locked.
The first large tranche, reported at roughly 20-30% of locked shares. It is tied to the first earnings report as a public company rather than to a fixed day count, so it moves with the actual reporting date.
The first of the staggered ~7% tranches that release on a fixed day count regardless of earnings.
Second scheduled tranche. Roughly halfway through the standard lockup window.
Third scheduled tranche.
Fourth scheduled tranche.
The last of the staggered tranches before the full release.
The second large tranche, reported at roughly 28% of locked shares, lands around Q3 results in the October-November window.
The standard lockup ends. All remaining shares held under the 180-day agreement become sellable. This is the date most people mean by "the SPCX lockup expiration".
A separate ~366-day lockup covers Elon Musk and select major holders, keeping the largest stakes off the market until 2027.
Rather than one cliff, SpaceX uses a staggered release, with the biggest tranches tied to earnings reports.
Why every unlock date is a supply event
A lockup is a promise by insiders and pre-IPO investors not to sell for a set period, so the market isn't flooded the moment a company lists. SpaceX's standard lockup runs 180 days, ending Wed, December 9, 2026. When each tranche frees up, the tradable supply grows - and on a stock whose entire personality comes from scarce supply, more shares to sell is a genuine headwind. Lockup expiries have a long history of pressuring hot IPOs precisely because new sellers finally can sell.
The flip side is that a deeper float is exactly what the forced index buyers need. Right now, passive funds have to source shares from a 4.3% sliver, which amplifies the squeeze. As unlocks add supply, those buyers get a bigger pool to fill their orders, and the violent two-way moves should calm. Supply and demand finally start meeting in the middle.
The one that stays shut: Elon Musk and select major holders are reportedly under a longer, ~366-day lockup, keeping the biggest stakes off the market until around Sun, June 13, 2027. The control block isn't going anywhere soon.
The SPCX float, and why 4.3% is the whole story
Public float is the share count actually available to trade, as opposed to shares outstanding, which counts everything including locked insider stock. SPCX listed with a float of roughly 4.3% of shares outstanding. For a company valued above $2 trillion, that is a remarkably thin slice of paper backing a very large market capitalization.
Two consequences follow. First, price moves get amplified: with few shares circulating, ordinary order flow pushes the quote much further than it would in a deep name, which is how SPCX out-traded SPY and QQQ on debut day without a correspondingly large ownership base. Second, the headline market cap is a mark rather than an exit price, because valuing the locked 95.7% at the price the free-floating 4.3% happens to trade at assumes the rest could clear at that level.
Short interest as a percentage of float
Short interest is reported by exchanges on a lag, twice a month, and is most useful when expressed as a percentage of float rather than of shares outstanding. On a stock with a float this small, the two figures differ enormously, and a short position that looks trivial against shares outstanding can be large against what actually trades. Expect the ratio to fall mechanically as unlocks widen the float, even if the absolute short position is unchanged.
If you bought on the open, you're not locked
One clarification for the retail crowd: the lockup applies to insiders and pre-IPO holders, not to shares you bought on the open market. If you grabbed SPCX during the debut, you can sell whenever you like.
The asterisk is broker policy rather than company policy. Retail buyers who received an IPO allocation through a broker are commonly subject to anti-flipping rules: sell the allocation inside the first 30 days and you may lose access to future IPO deals at that broker. That is a relationship consequence, not a legal restriction, and it does not apply at all to shares bought in regular trading after the listing.
SPCX lockup: common questions
When does the SPCX lockup expire?
SpaceX's standard lockup does not expire on a single date. It releases shares in stages, and the final 180-day release lands on Wed, December 9, 2026, counted from the June 12, 2026 IPO. Before that, smaller tranches free up at roughly 70, 90, 105, 120 and 135 days, with the two largest slices tied to the first and third quarter earnings reports.
When does the SpaceX lockup period end?
The standard 180-day lockup period ends Wed, December 9, 2026. A separate, longer lockup of about 366 days covers Elon Musk and select major holders and runs until roughly Sun, June 13, 2027.
When is the first SPCX lockup expiration?
The first meaningful release is tied to the first earnings report as a public company rather than to a fixed day count, which is why it is described as a late-July 2026 event rather than a precise date. The first purely calendar-driven tranche follows at 70 days from the IPO.
What is the SPCX float?
SPCX listed with a public float of about 4.3% of shares outstanding, which is unusually small for a company of its size. That scarcity is the single biggest reason the stock moved as violently as it did on debut. The float grows at each unlock date on the calendar above.
Does the SPCX lockup apply to shares I bought on the open market?
No. Lockup agreements bind company insiders and pre-IPO investors. Shares bought in ordinary trading after the listing carry no company-imposed restriction and can be sold at any time. The only caveat is broker-level anti-flipping policy, which is a relationship matter with your broker, not a legal lockup.
What were the lockup periods for retail brokers in the SpaceX IPO?
Retail buyers who received an IPO allocation through a broker were not placed under a company lockup, but many brokers apply their own anti-flipping rules, commonly counting a sale within the first 30 days against your access to future IPO allocations. Buyers who purchased SPCX on the open market after it began trading are not covered by either.
Why does a lockup expiration matter for the stock?
Each unlock increases the number of shares that can be sold. For a stock whose price reflects extreme scarcity, added supply is a genuine headwind, which is why lockup expirations have historically pressured hot IPOs. The offsetting effect is that a deeper float makes it easier for index funds and other forced buyers to source shares, which should reduce volatility over time.
Is Elon Musk able to sell SPCX shares?
Not under the standard schedule. Musk and select major holders are reported to be under a longer lockup of about 366 days, which runs until roughly Sun, June 13, 2027. The control block is not part of the staged releases through 2026.
The 60-second version
SPCX's defining feature is a ~4.3% float - and it won't last. The lockup releases shares in stages rather than on a single cliff date.
The standard lockup runs 180 days and expires Wed, December 9, 2026. The two biggest tranches are tied to Q2 and Q3 earnings.
Each unlock is a supply event: more sellable shares is a headwind for a scarcity-driven stock, but a deeper float also helps the forced index buyers fill orders.
Musk and major holders are locked ~366 days, to about Sun, June 13, 2027, so the control block stays put. And if you bought on the open, you're free to sell anytime.
