A generation ago, a venture-backed company went public in five to seven years, and an employee's stock options — good for ten — comfortably outlasted the wait. That arithmetic has quietly broken. Companies now stay private for a decade or more, but the options that make up most employee equity still expire on their original schedule.
This article explains how much longer "longer" really is, why a fixed option clock collides with a stretched private timeline, the specific ways longer private holds trap earned value, and how the market has responded with liquidity mechanisms that don't require an IPO. The throughline is simple: the same trend that keeps great companies private is what created the venture secondary market in the first place.
This is not tax advice. Exercising options and selling private shares can trigger significant tax — AMT on incentive stock option exercises, ordinary income on non-qualified options, and capital gains on a sale. Consult a qualified tax professional before you act on any of the mechanics described below.
Key concept
Employee equity has two clocks running against each other. One is the option's own life — a fixed term, usually ten years, that shortens abruptly to a matter of weeks when you leave. The other is the company's path to an exit, which has stretched to roughly twelve years. When the second clock runs longer than the first, earned equity can expire before it ever becomes sellable. Longer private holds don't just delay a payout; they can erase the option entirely.
How Much Longer "Longer" Really Is
The shift is not marginal. Venture-backed companies now take roughly 12 years to reach an IPO, nearly double the historical five-to-seven-year timeframe, and the median age of a US venture-backed company at exit rose from 4.9 years in 2013 to 8.2 years in 2023, per Orrick. The IPO has moved from the expected midpoint of a company's life to a distant and increasingly optional endpoint.
Ample late-stage private capital, the compliance burden of being public, and a public market that keeps shrinking have all pushed in the same direction: there is little reason for a well-funded company to go public on the old timeline, and often good reason not to. We've traced how a reopening exit market still doesn't change that base case in The Exit Market Is Reopening. The IPO Is Still Shrinking.
For the company, staying private longer is a feature. For an employee holding equity in that company, it's a lengthening of the one variable their compensation plan never priced in: how long they'd have to wait — and whether their instrument would survive the wait.
The Clock Employees Forget: Options Have an Expiration Date
A stock option is not a share. It's a time-limited right to buy a share at a fixed strike price — and that right ends on a date written into the grant. Two clocks govern it:
The ten-year term. Most option grants expire ten years after the grant date. Exercise before then or the right disappears — permanently, with no grace period. When exits happened in five to seven years, ten years was plenty of runway. Against a twelve-year private hold, the option can simply run out first.
The post-termination window. Leaving the company starts a much shorter countdown. The standard post-termination exercise period is often just 90 days, after which unexercised vested options are forfeited. (For incentive stock options, a separate 90-day IRS rule governs whether the favorable ISO tax treatment survives.) Since roughly half of startup employees leave within about three years — while the company has nine or more years left as a private entity — most employees hit this window long before any liquidity exists.
At that point the choice is stark: pay cash out of pocket to exercise — plus any tax due on the paper gain — and hold an illiquid private share for years, or walk away and let the equity lapse. The mechanics of that deadline are covered in depth in our Shareholder IQ guide on what happens when stock options expire.
Example
An engineer joins at Series B and is granted options with a $2 strike. She stays four years, fully vests, then leaves for a new role. Her company is now valued far higher on paper — but it's still six-plus years from any exit, and her 90-day post-termination window is running.
To keep the equity she earned, she has to write a check for the strike price on all her shares now, potentially owe tax on the spread between her strike and the current 409A value, and then hold an illiquid position for the better part of a decade. The alternative is to let vested, earned equity expire worthless. Neither is the outcome the grant was designed to produce.
Why Longer Private Holds Trap Equity Value
The expiration problem is the sharpest edge, but the longer private phase traps value in several overlapping ways:
1. Vesting no longer matches tenure. Four-year vesting with a one-year cliff was designed for a company that would exit shortly after an employee fully vested. Against a twelve-year hold, an employee can vest completely and still leave nine years before any exit — fully "owning" equity they may never be able to convert.
2. The instrument can expire before liquidity arrives. As above: the option's fixed life and short post-termination window can both close before there's a market to sell into. This is the mechanism that turns "delayed" equity into "lost" equity.
3. Value is locked in an illiquid position. Even for those who exercise and hold actual shares, private stock can't be easily sold or borrowed against. Earned net worth sits concentrated in a single private company for years — undiversified, unspendable, and exposed to the full risk that the eventual exit disappoints. A headline valuation is not cash, and it is often not even close to what common stock would realize; see The Last-Round Valuation Myth.
4. The downside case gets longer, too. A longer private life is also more time for the company to stall, raise a flat or down round, or wind down. For shareholders whose company never reaches an exit at all, we've written separately on what happens to your equity if your company never IPOs.
⚠️ "Vested" is not the same as "yours to keep." A vested option is earned but not permanent — it still has to be exercised before it expires, and exercising costs money and can create a tax bill on gains you haven't received in cash. The longer the private hold, the more likely that deadline arrives before any liquidity does.
How the Market Responded: Tender Offers and Secondaries
When the IPO stopped arriving on schedule, the pressure to give employees a way to realize value didn't disappear — it moved into the private market. That pressure is precisely what built the venture secondary market: a set of mechanisms for turning private equity into cash without waiting for a public listing.
The scale is now hard to dismiss as a niche. According to Carta, total US VC secondary transaction value reached an estimated $61.1 billion in the twelve months ending June 2025 — surpassing the combined value of all VC-backed IPOs over the same period. Employees are increasingly realizing value through the side door rather than the front.
Two structures do most of the work:
Company-organized tender offers. The company (often alongside investors) offers to buy back a limited slice of employee shares at a set price during a fixed window — a controlled, sanctioned liquidity event that doesn't require an IPO. Some of the largest private companies now run these on a schedule: SpaceX, for instance, has provided employee liquidity through roughly semiannual share sales, most recently at an $800 billion valuation in December 2025, per Fortune. For how these work from the shareholder's side, see Tender Offers Explained.
Direct secondaries. Outside of a company-run program, a shareholder can sell shares directly to a buyer, subject to the company's right of first refusal and any transfer restrictions. This is the broader market that has grown up around trapped private equity — and it's uneven: as we've documented, the secondary market is heavily concentrated in a small number of elite companies, so access to a buyer is far easier at a marquee name than at a mid-stage company.
The signal underneath the volume is the important part: a record amount of employee and investor equity is being converted to cash before any IPO, which tells you how much value the longer private phase had trapped in the first place. We unpack that signal at scale in What $14 Billion in Cashed-Out AI Equity Signals.

What This Means If You Hold Private-Company Equity
The point of understanding the mismatch is to see your own position clearly, not to act on a schedule someone else set. A few things the longer private phase makes worth knowing — considerations, not recommendations:
Know your own clock. Find the expiration date on your grant, and — if you've left or are thinking about it — the exact length of your post-termination exercise window. These dates, not the company's exit timeline, are what actually put your equity at risk.
Understand what you actually hold. Common stock behind a big headline valuation is worth far less than the marquee number once liquidation preferences are paid; share class and the preferred stack determine your real position, not the last-round price.
Understand what a share might realistically fetch. A secondary sale price can diverge meaningfully from the 409A value and from the last preferred round. Knowing that range is what lets you weigh holding against a liquidity option on real information rather than a paper mark. Our Shareholder IQ guide covers how private shares are priced.
None of this is a signal to sell or to hold. It's a case for knowing where your equity sits on both clocks — because in a market where companies stay private for twelve years, the shareholders who fare best are usually the ones who understood their position long before a deadline forced the question.
