EquityZen co-founder Phil Haslett confirmed what allocators have suspected for eighteen months: secondary transactions in private-company shares now approach the scale of primary venture rounds, marking a structural change in how pre-IPO equity moves between holders. The platform, which brokers trades in shares of companies like SpaceX and Stripe before they list publicly, reports transaction volumes that suggest the secondary market has become load-bearing infrastructure rather than edge-case liquidity.
The shift began during the 2021-2022 liquidity drought when venture-backed companies delayed IPOs and employees holding vested options needed exit paths. What started as founder-and-employee liquidity evolved into institutional repositioning as limited partners demanded redemptions from venture funds that had no natural exit events. EquityZen and competitors including Forge Global and Nasdaq Private Market now facilitate trades where the seller is as likely to be a crossover fund trimming exposure as an engineer cashing out four-year-old RSUs. The bid-ask spread on marquee names tightened from 18-22% in early 2023 to 8-12% today, signaling deeper pools and more sophisticated counterparties.
This matters because secondary pricing now front-runs public-market re-ratings before companies file S-1s. When a late-stage AI infrastructure company trades at $18 billion on secondary platforms while the last primary round priced at $12 billion eighteen months prior, allocators receive real-time signals about institutional appetite that venture markups cannot capture. The secondary market has become the derivatives layer for private equity—hedging exposure, establishing basis for tax-loss harvesting, and allowing concentration bets without waiting for a liquidity event the company controls. Family offices that bought Databricks shares at $38 billion in secondaries now hold positions priced near $55 billion without touching a primary round.
The composition of buyers changed too. Early EquityZen flow came from accredited individuals treating private shares like collectibles. Now institutional buyers—hedge funds running private-public arbitrage strategies, sovereign wealth funds building pre-IPO stakes, and single-family offices treating secondaries as standalone allocations—account for the majority of dollar volume. The platforms credential these buyers with the same KYC rigor as prime brokers, and settlement mechanics now mirror public-market standards with T+5 closes instead of the 60-90 day escrows common in 2019. When a secondary transaction closes in five business days with wire-transfer finality, the market has professionalized past the point of reversion.
Allocators should track three forward indicators. First, whether platforms begin offering margin against private-share positions, which would signal that custody and valuation have reached prime-brokerage standards. Second, the spread between secondary pricing and the next primary round—widening spreads indicate bifurcated demand where insiders see risks public buyers don't. Third, velocity: if the same company's shares trade multiple times per quarter on secondary platforms, the float has fragmented enough that price discovery happens outside the cap table the company controls. That final shift—when secondary liquidity rivals public float in names like Stripe or Plaid—will arrive in Q2 2025 for the top fifteen venture-backed companies by secondary volume.
The IPO as the definitive liquidity event has already become optional for employees and early investors. The question now is whether it remains essential for the company itself, or whether secondary markets provide enough continuous liquidity that public listings become a branding choice rather than a capital necessity.
The takeaway
Secondary private-share volume now matches primary rounds, with tighter spreads and institutional buyers reshaping pre-IPO price discovery.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
