SpaceX’s Lockup Expiration Just Started. Here’s What to Do With Your Shares.
On August 6, 2026, roughly 911.5 million shares of SpaceX (Nasdaq: SPCX), worth an estimated $116 to $123 billion, became eligible to trade for the first time. If you're a SpaceX employee, this is the first of five scheduled unlock dates between now and mid-December, and each one is a separate decision point for your equity, your taxes, and your financial plan.
Here's what happened, what's still ahead, and what to actually think about before the next window opens.
What Happened on August 6
SpaceX didn't use the standard single 180-day lockup most IPOs use. Instead, it staggered the release into tranches. The first one hit two trading days after SpaceX's first earnings report as a public company, freeing up about 20% of previously restricted shares and expanding the freely tradable float from roughly 4.9% to 11.8% of shares outstanding.
The stock had already been sliding into the release, opening near an all-time low around $105 before recovering to close up somewhere between 2.6% and 6.1%, depending on the source. That's a useful early signal: the "flood of selling crashes the stock" narrative didn't play out, at least not on day one.
If you're weighing whether to sell any of your own SpaceX shares this quarter, that's a conversation worth having before your next vesting or unlock date, not after. [Book a free intro call →]
The Remaining Unlock Schedule
| Timing | What's Expected |
|---|---|
| ~Aug 12, 2026 | Next tranche, roughly 319M additional shares |
| Sept–Oct 2026 | Further tranches (exact dates not yet confirmed publicly) |
| Late Oct/Nov 2026 | Largest remaining release, tied to Q3 earnings |
| Dec 8, 2026 | Full 180-day lockup expiration (all remaining employee/insider shares free) |
By year-end, more than 4 billion shares are expected to be tradable in total, well beyond the initial 911.5 million. (Elon Musk's ~6.4 billion shares are a separate block and stay locked until June 2027.)
Each of these is its own liquidity decision, not one all-or-nothing moment. That matters, because it means you get multiple chances to sell in a tax-efficient, diversified way rather than being forced into a single cliff. Exact dates for the September/October tranches aren't locked in yet, so this is worth revisiting as they're confirmed.
What History Says About Lockup Expirations
Lockup-day stock moves are genuinely mixed. Facebook's biggest 2012 release closed up 12.5%; Twitter's 2014 unlock dropped 17.7% in a day; Uber and Snap both slid for weeks around their releases. The one consistent pattern researchers point to isn't the day itself. It's a 3 to 7% drift down in the two weeks before an unlock, as the market prices in expected supply.
Translation: don't try to time the exact day. Have a plan going into the window, not a reaction after it.
What This Means For Your Financial Plan
If a big share of your net worth just became a highly concentrated, newly liquid stock position, a few things are worth putting on your radar now:
Diversification is usually the priority, not all-or-nothing. For most employees who now hold a large, concentrated position in a single stock, selling a meaningful portion into diversified holdings (spread across one or more of the scheduled unlock windows) is the standard move to manage concentration risk. How much and when depends on your tax situation, other holdings, and goals, which is exactly what a plan should map out before the next window.
Your tax treatment depends on what you actually hold. RSUs, NSOs, ISOs, and directly purchased shares are all taxed differently, and with unlock dates spanning two tax years (2026 and 2027), the order you sell in matters.
Estimated taxes follow the sale, not the vest. Capital gains aren't withheld the way payroll income is. A Q3 sale generally has an estimated tax deadline of September 15; a Q4 sale, January 15.
State residency changes the math. California taxes capital gains as ordinary income; no-income-tax states don't. Two employees selling identical shares can land on very different after-tax outcomes.
Company policy still applies. Legal eligibility to trade doesn't override internal blackout periods, insider trading policies, or 10b5-1 plan requirements.
This is exactly the kind of concentrated-equity decision our clients bring to us: mapping out which windows to sell in, how much to diversify, and what it does to your tax bill across two years.
The Bottom Line
The first tranche came and went without a dramatic selloff, but four more scheduled releases are still ahead of a stock that's been volatile since its June debut. Whatever happens with this week's "extra" shares has limited bearing on October or December. Those are separate decisions, on separate dates, that separately affect your liquidity and your tax bill.
If you're holding SpaceX equity and haven't mapped out a selling and diversification strategy across the remaining windows, now, before the next tranche around mid-August, is the time to build one.
