What Secondary Markets Now Tell Institutional Investors
The moment a company files its S-1 is not when price discovery begins. It has already been happening, quietly, on platforms like Forge Global, EquityZen, and Hiive. Accredited investors have been trading private shares for months. That trading activity leaves a signal: a continuous, capital-weighted price stream ahead of any public offering.
The question is whether that signal is reliable. Does secondary market pricing before an IPO actually predict where the deal lands? And if so, how far in advance, and with what precision?
This article examines that question using three recent case studies and the structural mechanics behind how information moves from private markets into final offer prices.
The Mechanics of Pre-IPO Price Discovery
Private secondary markets function as alternative trading systems. They connect sellers, typically founders, early employees, and early-stage investors, with accredited buyers seeking pre-IPO exposure.
Two structural features determine how much pricing information these platforms generate.
Order book transparency. Hiive publishes a live order book with hourly bid and ask updates. That creates an observable clearing price at any moment. Forge Global launched its Forge Price model in September 2024, calculating a daily indicative price for approximately 250 pre-IPO companies. The model synthesizes secondary market transactions, funding round data, and platform indications of interest. EquityZen uses deal-by-deal pricing with no live order book, making its price discovery less continuous than Hiive or Forge.
Bid-ask spread as a quality signal. Tighter spreads indicate more active two-sided markets. AltStreet's platform analysis noted Forge's median bid-ask spread at 6.4% in Q2 2024, down from a three-year median of 11.4%. Narrowing spreads as an IPO approaches suggest increasing consensus on valuation, which is a meaningful signal in itself.
Neither platform creates a direct analogue to an order book on a public exchange. Liquidity is thinner, trading windows are constrained by company-imposed blackout periods, and right-of-first-refusal clauses can terminate transactions after weeks of process. AltStreet's comparison of pre-IPO platforms noted an 18% ROFR exercise rate on Hiive direct transfers in 2024.
Despite these constraints, the volume and pricing data that does transact carries information. The question is how much.
Information Production Theory Applied to Secondary Markets
In standard IPO theory, investment banks run a book-building roadshow to extract demand signals from institutional investors. The bank collects indications of interest at different price points, then sets an offer price that balances issuer proceeds against enough underpricing to keep demand intact.
Secondary markets run a parallel process, earlier and continuously. They do not aggregate demand as efficiently as a managed roadshow, and they attract a different investor base. But they do reflect the same underlying question: what is this company worth, and at what price does capital move?
Underwriters and institutional bookrunners monitor secondary market activity before filing. A consistent price on Forge over several months establishes a reference point. Sharp volume increases two to four weeks before an S-1 is filed often precede formal announcements, suggesting some participants have early access to pre-marketing conversations.
The relationship between secondary market prices and final offer prices depends on three specific factors.
- Share class consistency. Secondary platforms trade common shares, often at a 20% to 40% discount to preferred shares from the same funding round. Preferred shareholders hold liquidation preferences and anti-dilution protections that common holders do not. A secondary market price for common shares is not directly comparable to a venture round price for preferred shares, or to an IPO offer price that reflects a different share class and capital structure entirely.
- Cap table restructuring. When a company recapitalizes or splits shares before going public, pre-split secondary prices become incomparable to post-split IPO prices without adjustment. SpaceX is the most prominent recent example.
- Timing of the signal. Secondary market prices tend to converge on the eventual IPO range roughly six to nine months before filing, when roadshow conversations begin informally. Prices closer to the filing date carry more information than prices from 18 months prior.
Three Case Studies: Figma, Cerebras, and SpaceX
Figma (July 2025)
Figma priced its IPO at $33.00 per share on July 30, 2025, listing on the NYSE under ticker FIG. CNBC reported the deal priced above its expected range.
Secondary market data from Forge and Hiive in the months before filing showed Figma trading in the $25 to $28 range. That placed the final offer price at an 18% to 32% premium to the last secondary trades.
The first-day close of $115.50, a 250% gain over the offer price, reflected a significant underestimation of public market demand. Six months later, the stock had pulled back to approximately $22, below the IPO price, a decline that lines up closely with Figma's lockup expiration timeline.
What the secondary signal captured: directional momentum and investor appetite. The consistent bid activity at $25 to $28 confirmed genuine demand before the roadshow. It did not capture the scale of institutional demand that emerged during book-building or predict the day-one volatility.
Cerebras (May 2026)
Cerebras priced its IPO at $185.00 per share on May 13, 2026, listing on Nasdaq under ticker CBRS. CNBC reported the deal was approximately 20 times oversubscribed, prompting the range to be raised twice before final pricing. The initial filed range was $115 to $125 per share. It moved to $150 to $160 before pricing above that at $185.
Hiive data showed Cerebras trading as high as $187.53 in early 2026 before the IPO, with earlier secondary transactions in the $102 to $107 range. Nasdaq Private Market estimated a pre-IPO price of approximately $118.11 per share as of May 13, 2026, the day before listing.
Forge confirmed Cerebras raised $5.55 billion at an implied valuation of $56.43 billion in the IPO, per its Cerebras IPO page.
Watching Forge's pricing page for Cerebras in the weeks leading up to the listing, the price climbed steadily rather than jumping suddenly, which lines up with what the eventual 20x oversubscribed book confirmed once book-building formally started.
What the secondary signal captured: the initial Hiive range of $102 to $107 aligned closely with the originally filed range of $115 to $125. But the final offer price of $185 significantly exceeded where the secondary market was trading. The 20x oversubscription during book-building produced an upward price revision that secondary market activity alone had not anticipated. The secondary signal gave an accurate floor but missed the ceiling.
SpaceX (June 2026)
SpaceX is the exception that clarifies the framework's limits.
Secondary trades on Forge and Hiive in the months before the IPO showed SpaceX changing hands at $595 to $832 per share. The final offer price was $135 per share. That appears to be a massive miss until the cap table adjustment is applied.
SpaceX restructured its share count significantly before going public. The pre-IPO secondary prices reflected a smaller, pre-restructuring share count. The post-restructuring IPO shares represent a different unit of ownership. As Wikipedia's SpaceX IPO entry documents, SpaceX sold 555.56 million Class A shares at $135, implying a $1.77 trillion valuation.
Without adjusting for share count changes, the secondary market price and the IPO offer price are not comparable figures. This is not a pricing miss. It is a measurement inconsistency.
What the secondary signal captured: the sustained, high secondary price activity confirmed intense institutional demand well before the offering. As Forge's own insights page noted, SpaceX was one of the most actively followed issuers in the secondary market before its June 12, 2026 listing.
What the Data Shows Across All Three
Company | Last Secondary Price Range | Initial IPO Range | Final Offer Price | Delta: Secondary to Offer |
Figma (July 2025) | $25–$28 | $27–$30 | $33.00 | +18% to +32% |
Cerebras (May 2026) | $102–$118 | $115–$125 | $185.00 | +57% to +81% |
SpaceX (June 2026) | $595–$832 (pre-split) | Fixed at $135 | $135.00 | Not directly comparable |
The pattern across Figma and Cerebras shows secondary market prices consistently below the final offer price, with the gap driven by the scale of institutional demand revealed only during book-building. Secondary platforms capture sentiment and directional momentum. They do not capture the full information extraction that a managed roadshow produces.
The Limits of the Secondary Market Signal
Three structural constraints define what secondary market data can and cannot tell institutional investors.
- Thin liquidity. Secondary markets facilitate far fewer transactions than public exchanges. A median bid-ask spread of 6.4% on Forge reflects a market that is active but illiquid compared to exchange-traded equities. A small number of transactions can move the displayed price significantly in either direction.
- Unverified disclosure. Investors on secondary platforms trade without access to audited financials, pending litigation details, or information produced during the formal SEC review process. The S-1 filing typically contains material information not available to secondary market participants beforehand.
- Institutional demand at scale. Secondary market buyers tend to be individual accredited investors and smaller institutional funds. The roadshow reaches the largest institutional allocators who can move hundreds of millions into a deal. That scale of demand is not visible in secondary market activity until the book-building process formally begins.
A secondary market price is best read as a demand floor. It tells you that sophisticated, capital-committed participants value the company at least at this level. It does not tell you where the roadshow will be.
How to Use This Data Practically
For institutional allocators evaluating an upcoming IPO, secondary market data serves three analytical functions.
First, it provides an early baseline for valuation. A company consistently trading at $100 on Forge is unlikely to be priced at $50 in the IPO without a material deterioration in the business. It establishes a floor the underwriter is unlikely to break.
Second, volume changes matter more than price levels. A sudden increase in transaction frequency or a sharp narrowing of the bid-ask spread on Hiive two to four weeks before a formal filing often precedes the S-1 announcement. That pattern appeared in both the Figma and Cerebras timelines.
Third, the secondary-to-IPO delta varies by deal type. VC-backed AI infrastructure companies in 2025 and 2026 showed larger deltas between secondary prices and final offer prices than their secondary trading activity suggested. That gap reflects the premium that scale institutional demand adds during book-building, which secondary markets cannot pre-empt.
Frequently Asked Questions
Does a higher secondary market price guarantee a higher IPO price?
No. Secondary prices reflect demand from a thin, accredited-investor pool. Final offer prices reflect broader institutional demand gathered during book-building. Cerebras's secondary range of $102 to $118 preceded an offer price of $185, a much larger gap than secondary activity suggested.
Why do secondary prices often sit below the eventual IPO price?
Secondary shares are typically common stock, not preferred. They carry fewer protections and thinner liquidity. That structural discount tends to compress relative to the offer price once institutional demand is formally gauged.
Is secondary market data accessible to all investors?
Forge Price data is available through Forge's platform and via Yahoo Finance integration announced in March 2025. Hiive's live order book is accessible to registered accredited investors. Full transaction-level datasets require platform subscriptions or direct access.
How does cap table restructuring affect pre-IPO price comparisons?
When a company changes its share count before listing, pre-restructuring secondary prices and post-restructuring IPO prices measure different units of ownership. Any comparison requires adjusting for the share count change before concluding pricing accuracy.
