IPO Timeline Reality: Lockups, Blackouts, and What the First Year Really Looks Like

Here's the question I hear from almost every employee once an IPO becomes real: "When can I actually sell?"

It sounds simple. It isn't. Between the IPO date, potential early sell windows, a lockup period that may or may not follow the standard playbook, quarterly blackout restrictions that kick in once the lockup ends, and nuances by grant type and employee designation — the answer is layered. And getting it wrong is expensive, both financially and psychologically.

The goal of this article is to give you a precise, honest picture of your actual liquidity timeline — not the idealized one people assume, and not the overly cautious one that leaves you paralyzed. Just the real mechanics, with a month-by-month framework for year one.

I'm going to assume a June 2026 IPO throughout for illustration purposes (SpaceX timing "rumors" tend to be pretty spot on after all). Adjust the calendar forward or back based on whatever the actual date turns out to be — the framework is the same.

Layer 1: Can You Sell at the IPO Itself?

Most employees assume the answer is no. The reality is: maybe, and possibly more than you'd expect.

There are two distinct ways employees sometimes get liquidity at or immediately around an IPO:

Selling in the IPO offering at the IPO price. When a company goes public, it typically sells a mix of newly issued shares (to raise capital for the company's operations) and, in some cases, existing shareholder shares. If SpaceX allows employees to sell in the offering itself, you would sell at the IPO price — the price set by the underwriters the night before trading begins. This is clean, certain, and at a known price. The tradeoff: it happens once, it's usually capped (often 10–20% of your holdings), and once that window closes, it's gone.

Selling in a short window around the first days of trading. Some IPOs include a brief early sell window — essentially a limited carve-out from the lockup — where employees can sell a small portion of shares in the open market at prevailing prices in the first day or week of trading. This is different from the IPO price itself: you're selling into a live market where the price is moving. Depending on how the stock trades out of the gate, this could be meaningfully higher (or lower) than the IPO price.

What's rumored for SpaceX: The number circulating among employees is approximately 10%-15% of holdings at the IPO. That has not been confirmed — and only time will tell. But it's realistic enough to plan around. If you could sell 10%-15% at the IPO, what's your plan? This isn't a rhetorical question. Having a pre-considered answer means you can act quickly and deliberately when the terms are confirmed. And you may need to; you'll likely have 2 days to 2 weeks to decide for an IPO (much less than the tender offers).

One important clarification on timing: selling in the IPO offering happens at a price set the night before the stock starts trading. Selling in the early-window carve-out happens at open-market prices in the first days of trading. These are different mechanics, different prices, and potentially different eligibility.

Layer 2: The Lockup Period — and Why SpaceX's May Not Be Standard

Once the IPO occurs and after any initial selling (Layer 1 above), a lockup period will (very likely) commence: a contractual restriction that prevents insiders and employees from selling shares for a specified period of time.

What's standard: 180 days. If SpaceX IPOs in June 2026, a standard lockup would expire around December 2026.

Why SpaceX's may be different: Lockup structures have been evolving the last few years. Also, generally speaking the more demand that exist for company shares, the more flexibility the company has to relax lockup restrictions. SpaceX's equity program has consistently been more employee beneficial than most (bi-annual tenders, ESPP programs, choice of equity grants). If demand for shares remains strong — they may have the power to make the lockup more friendly. A few scenarios to watch for:

• Shorter lockup period or tiered release. Some recent high-profile tech IPOs have negotiated shorter lockup periods (e.g. 90-days) or tiered structures (e.g. 50% release after 90 days, full release after 180 days). If SpaceX follows this route, your first major sell window could much earlier than December 2026. Of the 3 non-standard scenarios here, this is the one with highest odds IMO.

• Price-triggered early release. Some lockup agreements include a provision that allows partial early selling if the stock trades above a set price threshold for a sustained period (e.g. 50% release if the stock has 20 consecutive trading days above 130–150% of the IPO price). Given price-related, this scenarios requires careful monitoring.

• Tiered by employee type. Lockups can be tiered; for example that executives, officers, and directors face a longer lockup than general employees. This is least common, but they do occur.

The honest answer right now: we don't know the exact terms. But knowing the range of what's possible — and understanding your scenario in each case — is exactly what planning before the S-1 is for. Don't anchor on 180 days as a certainty when the actual structure could be meaningfully different.

Layer 3: When Does Each Grant Type Actually Become Liquid?

"Lockup expiration" doesn't necessarily mean the same thing for every share you own. Here's how liquidity works by grant type.

Shares you already own (RSU-vested stock, previously exercised ISOs or NSOs)

These are the shares most likely to be subject to the standard lockup and potentially eligible for the IPO/early sell window. Once the lockup expires, you can generally sell these during open trading windows.

Vested but unexercised options (ISOs and NSOs)

You own the right to buy these shares, but you don't own the shares yet. To sell, you first have to exercise. Most publicly traded companies allow cashless exercise (just as you've had in tender offers) — meaning you can exercise and sell simultaneously without needing to front the cash. But an always-available cashless exercise program typically takes time to get in place and may not be available for selling at the IPO (if allowed) or for an early lockup release (if that applies). You can generally still exercise at any time, but you'd need to have the cash to do so and wait a few days for the shares to be issued in order to sell them.

This creates a planning window. Some employees use the lockup period to exercise ISOs (as they now have certainty that the IPO has occurred, and some indication of market of pricing) — starting the qualifying disposition clock. The tradeoff: you're taking on price risk on those shares. If the stock declines materially between exercise and when you can sell, you'll have paid AMT on a value that no longer exists. That's the scenario that destroyed wealth for many early tech IPO employees in 2021–2022. It's worth modeling carefully before committing.

Unvested options and unvested RSUs

These continue to vest on their normal schedule regardless of IPO or lockup. Each vesting date creates a new batch of shares — but those newly vested shares are also subject to lockup until the lockup expires. Once you're post-lockup, newly vesting shares become sellable on their vest date during open trading windows (and not during blackout periods).

Layer 4: Blackout Periods — How They Actually Work

Blackout periods become relevant after the lockup expires, at which point you're a public-company employee subject to insider trading policies. Here's how they typically work:

The quarterly blackout cycle. Public companies close trading windows for employees around each quarterly earnings release — typically starting 2 weeks before the quarter ends and reopening 2-3 trading days after earnings are announced. SpaceX would report results quarterly, and in each quarterly likely have 5-8 where the blackout period applies.

What this means for your actual sell window. Once your lockup expires in (hypothetically) December 2026, a mock blackout calendar could look something this:

• December 2026: Blackout period starts on December 15th (2 weeks prior to quarter end)

• January 2027: Blackout period in effect all month

• February 2027: 4Q26 earnings reported Feb 18th. Open trading would begin 3 business days later on February 23rd.

• March2027: Open window the first couple weeks; Next blackout period begins on March 15th

In practice, you get roughly 6–8 sell weeks per quarter once post-lockup — not the other way around. Your effective annual sell window is closer to 24–30 weeks, not 52.

Why this matters for planning: You can't just decide to sell "sometime next year." Each open window is a discrete opportunity that closes. If you don't have a sell plan ready when the first window opens, you may spend the first window deciding and need to wait another 6–8 weeks for the next one. Or worse, panic sell (due to rushed timing). And the blackout periods will apply every quarter; a multi-year diversification plan absolutely needs to take that into account.

Layer 5: Pre-Clearance Individuals — The Extra Layer

For some employees, the picture gets one more layer of complexity.

Officers, directors, and employees with regular access to material non-public information (MNPI) — think: people who see quarterly financials before they're public, people who work on major contracts, senior engineering leaders with forward visibility into launch schedules or revenue-generating programs — may be designated as "pre-clearance individuals."

Pre-clearance means you need explicit approval from SpaceX's internal compliance team before placing a trade, even during open trading windows. In practice, this is manageable — the approval process usually takes a few days — but it means you need to be much more intentional with your selling (vs spontaneous in any way).

The standard solution for pre-clearance individuals is a 10b5-1 plan — a pre-scheduled, rule-based trading plan that you set up in advance and execute automatically during open windows, regardless of what you know at the time of execution. If you think you'll be a pre-clearance individual, setting up a 10b5-1 plan early (ideally during the lockup period, if allowed) gives you the most flexibility and the clearest legal protection.

The Month-by-Month Action Map: Year One

Here's the practical framework — assuming a June 2026 IPO and 180-day standard lockup. Adjust the calendar for whatever the actual IPO date turns out to be.

Pre-IPO (Now through June 2026)

• Finalize your equity inventory map: all grants, types, dates, vested/unvested counts

• Model your ISO exercise scenarios and AMT exposure

• Determine what you would sell at/around IPO if allowed

• Understand your likely insider/pre-clearance designation

• Draft your initial selling plan — even a rough one — so you're not making decisions for the first time under market pressure

IPO Month (June 2026)

• Final S-1 confirms: actual lockup terms, IPO selling eligibility, percentage limits

• If you're able to sell at IPO: execute according to your pre-made plan

• Note the exact lockup expiration date (put it in your calendar now; assuming it not dynamic)

• If exercising ISOs during lockup: model the AMT cost vs. benefit of starting the qualifying disposition clock now vs. waiting

Lockup Period (June – ~December 2026)

• You cannot sell — but this is not downtime

• This is when you finalize your post-lockup sell schedule: how much to sell, in which windows, from which lots (a future decision system publication will cover this in more depth)

• If you haven't yet: build your 3-bucket framework — sell now (first window), sell over time, keep long-term (again, a future decision system publication will cover this in more depth)

• Coordinate with your CPA on estimated tax payments for Q3 and Q4 — RSU vesting and any exercises during lockup may have created taxable income that was not withheld at adequate rates

• If eligible: set up your 10b5-1 plan so it's active for the first open window

• Consider tax-loss harvesting opportunities in your existing investment accounts to create offsets against future capital gains

Lockup Expiration (~December 2026)

• First major sell window opens — your plan should already be written (how much to sell and which tax-lots are optimal to sell from)

• Execute first tranche according to plan: don't improvise

• Note Q4 earnings blackout timing — first window may be shorter than expected

• For ISO shares: confirm qualifying disposition status before selling anything (unless intentionally conducting a disqualifying disposition)

Q1 2027 (January – March)

• Navigate blackout window

• Execute second tranche if on a systematic plan

• Tax year 2026 was a complex year: RSU vesting, possible exercises, IPO sales, first lockup sales all in one. Work closely with your CPA well before April 15

Q2 –Q4 2027

• Continue systematic sell plan during open windows

• Track lot selection and tax optimization on each sale

• Potentially utilize tax-optimized methods of divesting (a future decision system publication will cover this in more depth)

• (In less common situations) update your plan if things have materially changed

The Tax Year Timing Opportunity Nobody Talks About

One thing worth flagging that's easy to miss: if SpaceX IPOs in June 2026 and the lockup is 180 days, your first major sell window falls in December 2026 — still within the same tax year as the IPO.

That's actually a meaningful planning opportunity. If you can both exercise ISOs and sell (other) ISO-based shares in the same tax year (2026), there are scenarios where the standard tax liability and AMT liability partially offset each other in a single filing year rather than being split across two years. Your CPA and financial advisor need to model this scenario specifically. It doesn't work perfectly for everyone, but for some SpaceX employees with significant ISO positions, the alignment of IPO, lockup expiration, and tax year in 2026 creates some opportunities.

What You Actually Control

Reading all of this, it might feel like the timeline is entirely out of your hands. Some of it is — you don't control the IPO date, the lockup terms, or when earnings are reported.

But here's what you absolutely do control:

• Whether you have a (ideally written) plan ready before each window opens

• Which shares you sell and in what order (this is where taxes are won or lost)

• Whether you're making decisions from a place of preparation or reaction

• How much concentration risk you carry into and through the lockup

The employees who navigate IPOs well aren't the ones who got lucky with timing. They're the ones who understood the mechanics far enough in advance that when the window opened, execution was the only thing left to do.
