Most articles about selling pre-IPO shares assume you hold shares directly — either as a company employee, a former employee who exercised options, or an early investor who received shares in a primary round. But a large and growing portion of secondary market sellers hold their position through a special purpose vehicle: an LLC or limited partnership that was formed specifically to hold shares in one company. Selling out of an SPV is a materially different transaction, and sellers who do not understand the distinction often walk away with less than they expected.
What it means to hold through an SPV
When you invest in a pre-IPO company through an SPV, you become a limited member or limited partner of that vehicle. The SPV itself is the legal shareholder on the company's cap table. You own an interest in the SPV — not shares in the company directly. This layered structure has implications for every stage of a secondary sale.
First, the SPV's operating agreement governs what you can do with your interest. Most SPV operating agreements restrict transfers: you cannot simply sell your membership interest to anyone without either the general partner's (GP) written consent, or a specific transfer rights provision allowing secondary sales. Before you approach a marketplace or a buyer, read your operating agreement's transfer section carefully. If the GP's consent is required and the GP is unresponsive or adversarial, your ability to sell in the secondary market is limited regardless of what any buyer is willing to pay.
Second, a right of first refusal (ROFR) may apply at two levels. The underlying company may have a ROFR over transfers of its own shares — but because the SPV, not you, is the named shareholder, the company's ROFR may not be triggered at all when you sell your SPV interest. This is one reason SPV interests sometimes transfer faster than direct shares. However, the SPV's own operating agreement may include a separate ROFR or right of first offer (ROFO) in favor of the GP or other existing LP investors. Check both levels before assuming your sale can proceed immediately.
Fees and carry reduce your net proceeds
A direct shareholder who sells in a secondary market receives sale proceeds minus the marketplace's transaction fee and any applicable taxes. An SPV interest seller faces those same costs — plus any economics the SPV's operating agreement reserves for the GP.
Carry — sometimes called carried interest — is the GP's share of profits above a preferred return or hurdle. If your SPV operating agreement specifies 20 percent carry above a 1x preferred return, and you sell your interest at a gain, the GP takes 20 percent of the net gain before you receive the balance. On a position that has grown 3x, that carry can represent a meaningful reduction to your realized proceeds. Run the math before you list.
Before calculating whether a secondary sale makes sense at a given price, model the full net-proceed stack: gross sale price, minus marketplace transaction fee, minus any SPV transfer fee, minus carry on the gain, minus applicable taxes. The number you are left with is what you actually receive. It can differ substantially from the headline bid.
Tax treatment: partnership interest sale vs. share sale
When you sell a direct shareholding, the gain is taxed as a capital gain — long-term if you have held for more than twelve months, short-term otherwise. The mechanics are straightforward: proceeds minus cost basis equals gain.
When you sell an SPV interest, you are selling a partnership interest (assuming the SPV is taxed as a partnership). The tax treatment is generally still capital gain, but the cost basis calculation is more complex. Your basis in the SPV interest has been adjusted over time by your allocable share of the SPV's income, losses, and distributions — tracked on the K-1 schedules you received each year. If you did not track your adjusted basis carefully, work with a tax professional to reconstruct it before calculating the gain on a secondary sale. An incorrect basis can mean overpaying or underpaying tax, both of which create problems.
Qualified Small Business Stock (QSBS) treatment under Section 1202 is another distinction worth examining. QSBS exclusion generally requires that you hold qualified stock of a C corporation directly. Holding via an SPV structured as a pass-through partnership may or may not preserve QSBS treatment depending on how the SPV was structured and whether the look-through rules apply. This is a question for a qualified tax attorney, not a secondary marketplace — but it is worth raising before you sell, because the potential exclusion can be substantial.
At a liquidity event: how SPV mechanics change your outcome
If you hold through an IPO rather than selling in a secondary transaction, the SPV itself will receive shares (now publicly traded) or cash proceeds at the exit event. The SPV then distributes to LPs according to the waterfall in the operating agreement. This distribution takes time — GPs typically need to coordinate tax filings, arrange share distributions or cash conversions, and comply with any post-IPO lock-up that applied to the SPV's shares.
That post-IPO lock-up is a point sellers frequently miss. An IPO lock-up typically applies to the company's major shareholders and insiders. Whether the SPV is subject to lock-up depends on how large its position is and whether the GP signed a lock-up agreement with the underwriters. If locked up, SPV investors cannot receive their shares or proceeds for the lock-up period — commonly 90 to 180 days after IPO — regardless of what the public price does in the interim.
- Confirm whether your SPV's operating agreement specifies a distribution timeline post-exit, and whether the GP has discretion to delay.
- Ask the GP whether the SPV has signed any lock-up agreement with the company or underwriters, and what the expiry date is.
- Model the post-IPO distribution delay into your liquidity timeline — if you need cash within a specific window, a secondary sale before IPO may be more reliable than waiting for the SPV to distribute.
When a secondary sale of an SPV interest makes practical sense
Despite the added complexity, there are real advantages to selling an SPV interest rather than a direct position in some situations. Because the company's ROFR often does not apply to SPV interest transfers, the transaction can close faster. The documentation is standardized — an assignment of membership interest rather than a full share transfer agreement — which reduces legal friction. And in cases where the company has been unresponsive to direct transfer requests, the SPV layer can provide a path to liquidity that direct shareholders do not have.
The question to answer before listing is whether the carry, fees, and GP consent requirements leave you with net proceeds that justify the sale at the available bid. That requires a full model, not a back-of-envelope comparison to the last round price.
