Sell every share immediately; invest the after-tax cash at the market return for 1 yr, then liquidate. Diversified — no single-stock concentration risk.
Exercise + hold 1 yr
| Sale proceeds (year 1) | |
| LTCG tax (federal + state + NIIT) | $0 |
| Net at year 1 | $178,297 |
Sold 2,678 shares at exercise to cover strike + tax; 2,322 shares held 1 yr for LTCG.
Social Security + Medicare are payroll taxes (collectively called FICA) — they apply because you're exercising as a current employee.
Both columns are stated in year-1 dollars: sell-now proceeds compound at the market return and pay LTCG on the gain at year 1; any cash paid out of pocket on the hold side carries the same opportunity cost.
Net at year N — by hold period

Space Exploration Technologies Corp., doing business as SpaceX, is an American spaceflight, telecommunications, and artificial intelligence company headquartered at the Starbase development site in Starbase, Texas.

Elon Musk founded Space Exploration Technologies Corp. in March 2002 with the stated goal of reducing launch costs enough to make Mars colonization economically viable. SpaceX develops the Falcon 9 reusable rocket, the Starship heavy-lift vehicle, and Starlink, a low-Earth-orbit broadband network that reached 10.3 million subscribers across 164 countries by March 2026. The company reported $18.7 billion in 2025 revenue, with Starlink accounting for 61% of that total. SpaceX went public on Nasdaq in June 2026 under ticker SPCX, pricing at $135 per share and raising roughly $75 billion in the largest IPO in history.
Equity comp at SpaceX
- Twice a year (typically May and November), SpaceX organizes a window where employees can sell some of their vested shares to approved outside buyers. The industry name for this is a 'tender offer'. Because SpaceX is unlikely to IPO soon, these twice-yearly events are the main way employees can convert SpaceX equity into cash. Most planning questions for SpaceX employees ('when can I sell?', 'how much will I get?') really come down to the next tender's pricing and how many shares the company lets each employee sell.
- RSUs use double-trigger vesting. Two things must both happen before the shares are yours: (1) the normal time-based vesting completes, and (2) the company has a liquidity event (an IPO or an acquisition). Until both happen, you do not yet own the shares and you do not owe tax on them.

Use this calculator to estimate your SpaceX (SPCX) NSO exercise tax (federal, state, FICA), then compare selling now versus holding through the long-term capital gains threshold. Inputs are yours: grant terms, current price, your income, your state.
Example: at SpaceX (SPCX)'s last close of $108.37, exercising 5,000 NSOs with a $32.51 strike creates a $379,300 bargain element, taxed as ordinary income on the day you exercise. Combined federal + state + FICA on that bargain typically lands between $102,411 and $170,685 depending on your bracket and state. The calculator above computes the exact figure for your situation and compares selling now vs. holding through the long-term capital-gains threshold.

SpaceX equity questions
- How is a SpaceX NSO exercise taxed?
- Exercising a non-qualified stock option (NSO) creates ordinary income on the bargain element (the price on the day you exercise minus your strike), subject to federal income tax, state income tax, and FICA. The calculator above computes that tax for your SpaceX grant and compares selling the shares now against holding past the one-year mark for long-term capital-gains treatment.
- Does SpaceX grant ISOs, NSOs, or RSUs?
- Equity compensation at SpaceX typically takes the form of incentive stock options (ISOs), non-qualified stock options (NSOs), and restricted stock units (RSUs). Incentive stock options can trigger the alternative minimum tax (AMT) when you exercise. Restricted stock units are taxed as ordinary income when they vest.
- When did the SpaceX IPO lockup expire?
- SpaceX (SPCX) went public on June 12, 2026. The standard post-IPO lockup runs 180 days, so employee and insider shares generally became sellable around December 9, 2026. Confirm against your own grant paperwork, since some lockups release early or in stages.
- Do SpaceX RSUs use double-trigger vesting?
- Yes. SpaceX restricted stock units (RSUs) vest only when two things both happen: the time-based schedule completes, and the company has a liquidity event such as an initial public offering (IPO) or an acquisition. Until both occur you do not own the shares and owe no tax on them.
