Plan staged share unlocks: SpaceX's $123B example
Treat each unlock as a separate liquidity decision: track shares released, trigger status, tax cost, concentration, and sale size before you sell.
When your first restricted shares unlock, the trap is treating that window as the exit. The rule is to plan each window by shares released, trigger status, tax cost, concentration, and sale size.
Space Exploration Technologies Corp. (SPCX) sold 638.9 million shares at $135 in its June 12 IPO and raised $85.7 billion.
SpaceX structured the 180-day lockup as staged releases instead of one single-date release, so holders face multiple liquidity windows.
The first window is a liquidity decision, not a liquidation
The August 6, 2026 unlock was the Q2-earnings tranche, landing the second trading day after the August 4, 2026 report.
On August 6, 2026, insiders became eligible to sell up to 20% of restricted SPCX shares, about 911.5 million shares worth close to $123 billion.
The first tranche more than doubled the shares already available to the public.
More than 900 million SPCX shares unlocked that day while the stock rose more than 6% after closing near an all-time low around $108.
That day changed the question from whether the stock could absorb supply to how much of the next release a holder should sell.
The first window is often the most emotional because it is the first real chance to convert holdings into cash. Use the checklist before the first order.
The schedule turns one lockup into several decisions
The performance-based early-release bonus tranche failed to trigger because SPCX did not finish 30% or more above the $135 IPO price, or $175.50, on five of the ten pre-earnings trading days, so about 455.8 million bonus shares were pushed into the December 8 expiry.
After the Q2-earnings tranche, SPCX's schedule lists five time-based releases of about 7% of restricted shares each at 70, 90, 105, 120, and 135 days after the June 12 IPO.
SPCX's Q3-earnings release is tied to a second major unlock of about 28% of restricted shares, and the remaining 180-day lockup ends on December 8, 2026.
The same checklist works at every release
For each tranche, write down the fields below before you decide how much to sell.
- Shares released
- Trigger status
- Tax cost
- Concentration
- Sale size
Start with shares released, the new supply you can actually sell rather than the total in your account.
Next, note trigger status: whether the window is time-based, earnings-based, or price-based, and whether a missed condition pushes shares to a later date.
Then size the tax cost as the cash you need to set aside, not just the unrealized gain.
After the sale, concentration shows how much of your investable wealth remains in one company.
Finally, set sale size as the amount you can sell without making your personal decision depend on market reaction.
A small release may be mostly a tax and concentration decision. A large release also asks how much supply you are adding to the market at once.
Do not let a good price decide the whole sale. A good price can justify a larger sale, but it should not erase the tax cost or the concentration you are trying to reduce.
Do not let a bad price stop all sales. A bad price can justify a smaller sale, but it should not leave you fully concentrated in one company.
When a trigger fails, move the shares to the next date on your calendar and re-run the checklist. The missed trigger changes the timing, not the need to plan.
When a trigger fires, mark the window as active and decide the sale size before the trading day. The checklist should be filled out before you place an order, not after the price moves.
Run the checklist on the first SPCX unlock: the released block was large, and the trigger had already fired. The missed price trigger makes the later end date the planning date for the bonus block. The smaller routine windows are chances to reduce concentration before the bigger window. The final remainder is a closing step, not a first look, because anything still restricted becomes sellable at the end of the lockup.
Elon Musk's window is later: his holding of more than 6.4 billion shares is locked for 366 calendar days without an early-release provision, making it unsellable until June 12 or 13, 2027.
