How to Sell Pre-IPO Shares on the Secondary Market
You have significant value in your startup equity, but no IPO in sight. You can wait — or you can explore selling through a secondary marketplace. This guide explains who can actually do this, how the process works, what it costs in taxes, and what you'd be giving up by selling early.
What shares can you actually sell?
Not all equity is transferable. Before contacting any platform, understand what you hold:
| Equity type | Eligible for secondary sale? | Notes |
|---|---|---|
| Early-exercised shares (83(b) election filed) | Yes — you own the shares | Most common scenario on secondary market. Watch ISO qualifying-disposition clock. |
| Exercised vested options (ISOs/NSOs) | Yes — you hold the actual shares | Check whether you're within a 90-day post-termination window for ISOs. |
| Pre-IPO RSUs (double-trigger, undelivered) | No — no shares yet | Double-trigger RSUs aren't delivered until IPO + service condition. You hold a contractual right, not shares. |
| Unvested options (vesting not complete) | No — not yet yours | Unvested options cannot be transferred. Some platforms facilitate same-day exercise + sale after vesting. |
| Vested unexercised options | Generally no — you can't transfer an unexercised option | You'd need to exercise first, then sell the resulting shares. That requires cash to exercise and triggers its own tax event. |
The bottom line: secondary markets primarily serve employees who (1) early-exercised options at a low 409A price, or (2) exercised vested options and are now holding common stock. If your equity is entirely undelivered RSUs, you generally cannot access secondary liquidity until the company runs a tender offer or goes public.
The major platforms
As of 2026, three primary marketplaces handle most secondary volume in venture-backed private companies:
- Forge Global (now Schwab Private Markets). Forge was acquired by Charles Schwab in late 2025. It's the largest by volume and offers institutional-grade compliance infrastructure. Minimum position sizes typically $100K+. Works primarily with accredited investors on the buyer side.
- EquityZen. Focuses on structured funds that pool multiple investors to buy a single seller's stake — useful when no single buyer meets your full position size. Minimum seller positions vary by company, often $50K–$200K.
- Hiive. A newer entrant growing rapidly (>$100M/month in transactions as of 2025). Known for faster matching times and a leaner process. Operating primarily in high-profile companies (SpaceX, OpenAI, Anthropic, major unicorns).
All three platforms primarily operate in late-stage companies with established valuations (typically Series D or later). They are not useful for seed-stage or early-Series A equity where there is no liquid buyer market.
How a secondary sale actually happens
The process is longer than most employees expect. Plan for 60–120 days from first contact to cash in hand.
- Contact a platform and qualify. You submit your equity details (grant type, grant date, share count, 409A, company name). The platform assesses whether there's buyer demand for your company and whether your position size meets their threshold.
- Price negotiation. You'll receive an indicative bid from a buyer. In 2026, private company shares typically trade at a 25–45% discount to the last preferred round valuation — sometimes more for companies without recent funding or with uncertain IPO timelines.1
- Legal and company notification. Once you accept a price, the platform initiates paperwork. Most equity plans require company consent or at least company notification before a transfer can proceed. This is where ROFR is triggered.
- Right of first refusal (ROFR) window. Your company typically has 30–60 days to exercise its ROFR and purchase the shares itself at the price you negotiated with the third-party buyer. If the company passes (or the window expires), the sale proceeds to the original buyer. The outcome — cash to you — is the same either way. The identity of the buyer changes.
- Closing and settlement. Transfer agent paperwork is completed, shares are transferred, and proceeds are wired. This closing step can add 2–4 weeks to the total timeline.
Tax treatment on a secondary sale
The tax depends on what type of equity you're selling and how long you've held it.
Common stock / restricted stock (early exercise shares)
If you early-exercised and filed a timely Section 83(b) election, you own the shares from exercise date and your holding period starts at exercise. A sale held more than 12 months from exercise qualifies for long-term capital gains rates:
| MAGI (single) | Federal LTCG rate | + NIIT | Effective rate |
|---|---|---|---|
| Up to $49,450 | 0% | 0% | 0% |
| $49,451–$552,850 | 15% | 3.8% (above $200K) | 15% or 18.8% |
| Above $552,850 | 20% | 3.8% | 23.8% |
Source: Rev. Proc. 2025-40 (2026 LTCG thresholds).2 NIIT applies when MAGI exceeds $200,000 single / $250,000 MFJ.3 California taxes capital gains as ordinary income (up to 13.3%); no preferential LTCG rate.
ISOs: the qualifying-disposition trap
If the shares you're selling came from exercising Incentive Stock Options, the qualifying-disposition rules apply:4
- Qualifying disposition (preferred): You held the shares more than 2 years from grant date AND more than 1 year from exercise date. Result: the full gain (from strike price to sale price) is long-term capital gain. No ordinary income at all.
- Disqualifying disposition (costly): You sell before meeting both holding periods. The spread at exercise (FMV at exercise minus strike price) becomes ordinary income — taxed at rates up to 37% federal — and only the gain above that FMV is capital gain.
Selling early to access secondary-market liquidity can trigger a disqualifying disposition on ISOs you've held for years, converting what would have been capital gain into ordinary income. Model this explicitly before accepting any buyer's price.
NSOs and already-vested-then-exercised shares
If you exercised NSOs, you already recognized ordinary income at exercise (the spread was W-2 income). The shares now have a stepped-up basis equal to that FMV. Any sale proceeds above that basis are capital gain, short or long term based on the 12-month holding period from exercise date. Selling on the secondary market doesn't change this analysis — it's the same as selling after an IPO.
QSBS: the most important consideration before you sell
If your startup qualifies as a C-corporation with gross assets under $50M at issuance, your shares may qualify as Qualified Small Business Stock (QSBS) under IRC § 1202. Post-OBBBA (enacted July 2025), the exclusion is:5
- 50% exclusion on gains after 3 years of holding
- 75% exclusion after 4 years
- 100% exclusion (up to $15M) after 5 years
Selling before 5 years means leaving a potentially massive exclusion on the table. If your position is worth $2M with a $100K basis, the 5-year 100% exclusion saves roughly $475,000 in federal capital gains tax compared to selling at the 3-year 50% exclusion mark. On a $5M gain, the difference between selling at year 4 (75% exclusion) vs. year 5 (100% exclusion) is ~$285,000 in additional federal tax.
California does not conform to the federal QSBS exclusion — gains are taxable at ordinary income rates regardless of holding period.
The economics: what does it actually cost to sell early?
Consider a senior engineer at a late-stage startup with 500,000 shares of common stock. Early-exercised at $0.50/share 3.5 years ago. Current 409A: $8.00/share. Secondary market bid: $5.00/share (37.5% discount to 409A). QSBS-eligible (C-corp, assets under $50M at issuance).
| Sell on secondary now (year 3.5) | Wait for IPO at $12/share (year 5.5) | |
|---|---|---|
| Gross proceeds (500K shares) | $2,500,000 | $6,000,000 |
| QSBS exclusion | 75% (year 3.5 = 4-year rate) → $562,500 excluded | 100% → $5,962,500 excluded (limited to $15M) |
| Taxable gain (federal, 23.8%) | $562,500 × 23.8% = ~$134K | ~$0 (full exclusion) |
| California tax (13.3%, no QSBS) | $2,225K gain × 13.3% = ~$296K | $5,962K gain × 13.3% = ~$793K |
| Platform fee (~3–5%) | ~$100,000 | — |
| Net proceeds (CA resident, federal 20% + NIIT + CA) | ~$1,970,000 | ~$5,207,000 |
In this example, waiting 2 more years — if the IPO happens and the stock performs — is worth roughly $3.2M more after tax. The decision is not just about the secondary market discount. It's about whether the IPO upside is real, the QSBS exclusion math, your personal liquidity need, and how confident you are in the company's trajectory.
When secondary sale makes sense anyway
Despite the economics above, there are legitimate situations where selling on the secondary market is the right call:
- Concentrated risk you cannot stomach. If your startup equity represents more than 40–50% of your net worth and the company's IPO is more than 2 years away, taking some chips off the table is rational diversification — not failure of nerve.
- IPO runway is genuinely uncertain. If your company has been in "IPO next year" mode for 3 years running, or if recent growth has stalled, the IPO premium you're waiting for may not materialize. A bird in hand matters.
- Specific liquidity need with high opportunity cost. Down payment on a house. Medical event. Career transition that requires capital. The after-tax cost of selling early may be lower than the opportunity cost of not having the liquidity.
- ISO expiration pressure. If you left the company and face a 90-day ISO window, you either exercise (and hold, taking AMT risk) or lose the options. Sometimes secondary sale of previously-exercised shares finances the exercise. See the post-termination ISO guide.
When to wait
- You're 18 months away from the 5-year QSBS threshold — the exclusion math is too compelling.
- IPO filing has been submitted or is credibly imminent. Lockup expiration may be 6–9 months away.
- Your holding period for ISO qualifying disposition is nearly complete — selling now triggers ordinary income treatment.
- The secondary bid is more than 40% below the last preferred valuation and the company is growing.
