The Market for Time: A Field Guide to Secondaries

The Structure, Purpose, and Durability of the Private Secondary Market

Private secondaries have become essential infrastructure for modern venture capital – an evolution we celebrate. As companies stay private longer and create more value along the way, their timelines increasingly outlast the holding periods of employees, early investors, and venture funds. The secondary market reconciles those clocks, offering a disciplined way to create liquidity without forcing a premature exit. More capital and more company-led liquidity make the private market healthier, and there is plenty of room for both.

The market’s success has made it more visible, but no more intuitive; attention has outpaced understanding. Private shares trade within a complex architecture of securities law, company consent, confidential information, and institutional practice. Those conditions shape who can transact, how prices form, and where risk sits. Drawing on fifteen years inside the market, this field guide brings those elements together into a single account of how the market actually works, what it is built to do, and why its defining conditions endure.

The information regime

The most important thing to understand about private markets is perhaps the easiest thing to miss – gaining access to an asset does not grant access to the information required to evaluate it.

Public markets have trained investors to expect access and information to come hand-in-hand, and for good reason. Nearly a century of securities law binds broad public market participation to mandatory disclosure: audited financials, prompt reporting of material events, Regulation FD, and insider-trading rules that constrain what a knowledgeable party can do with information others do not have. The rules serve a purpose – to put every participant, institutional or retail, in front of the same information at roughly the same time. The access is downstream of the disclosure. It was never the other way around.

Private markets are defined by the deliberate absence of those obligations. A buyer can gain economic exposure while financials, cap table context, prior-round pricing, transfer restrictions, and material company information remain available only to the issuer and a limited group of approved investors. The company chooses not to assume the disclosure obligations of a public company, and the investor is presumed¹ capable of proceeding without the protections that disclosure provides.

You cannot democratize the information in private markets without making them public markets. The information regime is not a feature of the market – it is the market.

An institutional buyer in a direct secondary may have spent years close to the company. It reviews financials under NDA, models the unit economics with a dedicated team, sees the cap table, knows what prior rounds priced at and why, and understands the restrictions governing the shares. A buyer purchasing exposure without explicit information access may have none of that, and may not know what is missing. Transactions that look identical on the surface can carry substantially different information, rights, and risks. So “democratize access without democratizing information” is not democratization. It is the orderly migration of risk toward whoever knows the least.

Broader participation in private markets can continue to be constructive, but the bargain must be described honestly. Private-market access does not carry the disclosure, price formation, or investor protections that make public markets broadly investable. Those differences are structural; they cannot be engineered away.

Opacity by design

Efficiency and transparency have become defining expectations of modern life, so a market that still runs on phone calls and confidential financials can appear, from the outside, like something to fix. But opacity in secondaries is not friction waiting to be removed – it is a generational operating condition. Transactions are bilateral, financials are confidential, and companies retain control over who can own their shares because discretion is central to the market’s design. Better data and technology can certainly improve execution within that framework. Even so, the market’s most basic facts – volume, price, and comparability – remain only partially visible.

Start with the simplest question you can ask about a market: how big is it? Jefferies estimated the broader global secondary market at a record ~$240 billion in 2025.² The direct secondary market is harder to size; bilateral trades generally leave no public trace. Measuring that market is a raise-your-hand-if-you’re-not-here problem: an entire universe of discreet institutional trades is structurally resistant to measurement. PitchBook estimates U.S. venture direct secondary volume at $40-155 billion based on reported tender and platform volume alongside a model of the stakes most likely to trade.

A range of more than $100 billion is about as precise as this market permits. The seller, buyer, and company that consented to a trade generally have neither an obligation nor an incentive to disclose it. While a platform can improve execution within the transactions it sees, its price discovery remains limited to only those transactions.

This market can display prices without producing price discovery.

In pursuing coveted access, new buyers may not fully appreciate that the private market does not offer the protections they know from public investing. The mistake is to treat access as the hard part. In public markets, getting in is the start of a set of protections; here, it is the end of them.

When a private price meets a public market

The limits of price discovery matter when a private price begins to travel. Facebook put private secondary market price formation to a public test, while the regulatory pressures surrounding its IPO helped rewrite the rules for the market that followed. As Facebook stayed private longer, employees and early investors needed a way to access their wealth; secondary trading platforms SecondMarket and SharesPost provided a venue. By any public market standard, trading was thin. Facebook was the marquee name on these platforms, representing 39% of SecondMarket’s ~$180 million of volume in Q4 2010. Thin as it was, it set an anchor. By early 2012, shares changed hands around $44; Mary Meeker later described that secondary valuation as the backdrop the IPO had to meet. Facebook went public in May 2012 at $38, the largest technology IPO to that point at $104 billion. The share price then slid to less than half its offering price and did not return to $38 for over a year. The company was sound, as was proven many times over; the private price simply did not survive broader public scrutiny. Thin secondary trading can anchor a price; only a broader market can test its durability.

There was reason for the public market to hesitate. Facebook’s amended prospectus showed slowing revenue growth, declining average revenue per user, and daily active users growing faster than ads delivered. Mobile use was accelerating with smartphone adoption, but meaningful mobile revenue had yet to follow, leaving investors unsure whether Facebook could transfer its advertising model from desktop to mobile.

So why would Facebook IPO into a paradigm shift for user interaction at a dicey price? Because it had a regulatory problem: the 500-shareholder cliff. A provision added to the Exchange Act in 1964 figured that if you’re big enough to have more than 500 shareholders, then you’re big enough to file public-company financials. Facebook was approaching that regulatory Rubicon: crossing it would mean carrying the costs of being public without the benefits of an offering, so it accelerated the IPO rather than be forced into disclosure. That trigger was pulled in part by the holders accumulating through secondary trading; a thin private market had helped set both the price the company was measured against and the clock it was running out.

The same cliff caused a different problem a year earlier. Goldman Sachs had structured an SPV through which private wealth clients could invest in Facebook as a single shareholder. The SEC opened an inquiry within weeks, and the U.S. offering was withdrawn. The episode put a spotlight on the 500-shareholder cap, which Congress addressed through the JOBS Act. The change came too late for Facebook but helped establish the modern order: private companies could remain private at scale, with secondaries providing liquidity along the way.

A market four decades in the making

Long before there was a platform or a product, there was a transaction.

In 1979, Thomas Watson Jr. – former president of IBM, son of the founder – was named U.S. Ambassador to the Soviet Union by President Carter. The post required him to liquidate his venture portfolio, which his college classmate and sailing buddy Dayton Carr had managed for years. So Carr bought him out. The first known private secondary transaction in venture history was a favor. Carr founded VCFA three years later; the firm raised the first dedicated secondary fund in 1984.

As private capital became institutional in the late 1980s, secondary infrastructure followed. Pension funds and endowments started building real private capital allocations, and once you have institutional LPs holding long-dated illiquid investments, you eventually need a robust market to trade them. Pantheon entered the secondary business in 1988. Coller Capital was founded in 1990, and Lexington Partners in 1994. By around 2000, the first billion-dollar institutional transactions were clearing.

What those institutions built preserved the character of the first transaction – bilateral, relationship-driven, discreet – while adding diligence conventions, negotiation norms, legal structures, and a dedicated buyer base. This market has operated in recognizable form since the days of dial-up internet.

The platforms most visible to the public arrived later and represent only the part of the market that can readily be seen. The direct market is almost certainly larger than published estimates suggest because the transactions most resistant to measurement are often the most private. What public commentary treats as an emerging market is a long-established corner of private capital, supported by information, judgment, and institutional infrastructure largely outside public view.

What the rules built, and why they hold

The market’s infrastructure was legislated in sequence, producing a complex and heavily regulated system with clear boundaries. That history explains many features that recent commentary mistakes for temporary inefficiencies.

The Securities Act of 1933 established the basic bargain: public offerings register and disclose; private offerings may proceed within defined exemptions without doing so.³ The door is not closed for its own sake. From outside, what lies behind it appears to have no ceiling: the possibility of owning a company before its value is visible to public markets. What is harder to see is that there is no floor either – no mandatory disclosure, no continuous market, and none of the protections available when a public investment goes wrong.

For decades, the door saw little traffic because companies went public early. Then, in the early 2000s, the timetable changed. The Nasdaq fell 78%, Enron and WorldCom collapsed, and investor appetite for young growth companies evaporated. Congress responded with Sarbanes-Oxley in 2002, strengthening public-company reporting and governance while materially raising the cost of being public. In one stroke, the rule written to protect public investors widened the gap between what a public shareholder is owed and what a private one is not.

The Facebook episode had already exposed the shareholder-count problem. The JOBS Act (2012) then raised the registration threshold to 2,000 and, more consequentially, excluded many employee shares. Sarbanes-Oxley had made public status more demanding; the JOBS Act made it possible to defer that status at much greater scale. Companies could remain private longer, support far larger shareholder bases, and rely on a secondary market that expanded in kind.

Together, they reset the clock.

The private-company lifecycle, once four to six years, stretched to fifteen years and beyond. High-value private companies now routinely outlast venture fund lives, deepening the duration mismatch from which much of the modern secondary market follows.

The public market shows the scale of the shift: 370 technology IPOs in 1999 became 34 in 2025; median age at listing rose from four to twelve; valuations fell from 43x sales to 14x.⁴ Companies now reach maturity while still private, creating a sustained need for disciplined liquidity well before an IPO or other final exit.

The same statutory machinery shapes who can operate at scale. Title IV of Dodd-Frank (2010) required many private-fund advisers to register with the SEC but preserved a lighter regime for traditional venture firms under the Venture Capital Exemption. The definition is specific: at least 80% of a venture fund’s capital must be deployed in qualifying investments, principally primary equity in private operating companies. Secondary purchases do not qualify. A firm meaningfully built around secondaries therefore sits outside the carve-out.

This rarely surfaces, and it is quietly decisive. A secondaries strategy faces a fork traditional primary firms ordinarily do not: remain below a 20% ceiling on nonqualifying investments, or register fully and assume full Form ADV disclosure, books and records, custody, and SEC examination obligations among others. The specialist’s toolkit – direct secondaries, structured primaries with embedded protections, company-led tenders, GP-led continuation vehicles – sits on the far side of that fork. Executing across private secondaries demands regulatory fluency, specialized processes, and relationships and judgment built across transactions and market cycles.

Liquidity infrastructure for a longer private lifecycle

Secondaries and public markets serve different moments in the same company lifecycle.

The market tested that proposition in 2025. CoreWeave, Circle, Figma, and others went public into receptive markets. At the same time, tender offers proliferated. Companies conducted 396 tender offers on Carta in 2025, up 62% from the prior year.⁵ PitchBook explicitly compared the two liquidity channels, finding that an estimated $61.1 billion in U.S. direct venture secondary transactions over the twelve months ending June 2025 exceeded the $58.8 billion in venture-backed IPO exit value over the same period.⁶

That coexistence matters. If secondaries merely filled the gap left by a closed IPO market, their use would recede as the window reopened. Instead, public offerings and structured liquidity expanded together. Secondaries provide liquidity throughout the years a company remains private; an IPO provides it when the company is ready to become public.

Strategic liquidity has become a core capability. The tender has moved from exceptional remedy to recurring corporate function: a structured program that gives employees and early investors an opportunity to sell, helps companies manage their shareholder base, and relieves pressure to go public before the company is ready.

Secondaries do not depend on companies remaining private forever. They exist because private ownership now lasts long enough, and encompasses enough value and enough stakeholders, to require an institutional system of liquidity before the final exit arrives.

What holds

Fifteen years inside this market produce a particular kind of conviction – not about predicting which companies will succeed, a task that requires rigorous analysis and still carries venture’s irreducible uncertainty, but clarity about how the market itself functions and why its defining conditions endure.

The private secondary market is opaque because the underlying companies are private and its participants choose discretion. It is bilateral because issuers, buyers, and sellers prefer negotiated transactions. It is institutional because operating well requires regulatory fluency, diligence capacity, patient capital, and relationships built across cycles. It is large, growing, and structurally necessary wherever company timelines exceed shareholder holding periods.

Unlike its foundational first transaction, the established participants are not doing anyone a favor. Companies gain a disciplined way to provide liquidity for employees and early investors. Long-tenured shareholders gain an exit when a fund’s clock runs down or personal circumstances change. Institutional buyers gain access to growth that increasingly occurs before public markets see it. Selling may reflect a fund reaching the end of its life, an employee buying a house, or an early investor realizing a decade’s return. Each party enters for reasons it can articulate, under terms it has negotiated.

It is worth being clear about what privacy is for. Private markets give companies room to experiment, invest, fail, and change direction without narrating every setback to a quarterly audience. Venture capital is one of the principal mechanisms through which a market economy finances that uncertainty years before an outcome is knowable, often for companies with little revenue, no collateral, and a substantial probability of failure.

The system funds many uncertain attempts in search of the few that matter and places the risk with investors expected to understand the odds, conduct the work, and withstand the losses. Confidentiality, transfer restrictions, and limits on participation are not incidental barriers. They are part of the machinery by which uncertain innovation is financed before it is ready for public ownership.

From outside, those boundaries can make the market look like a preserve for insiders. In practice, buyers of large private positions are among the most demanding participants in finance. They work from confidential company information, employ dedicated investment and legal teams, negotiate aggressively on behalf of institutional capital, and may spend months pursuing a transaction that never closes. A nine-figure block does not move casually. The difficulty of moving it is one reason liquidity remains constrained even in a massive market.

All of which raises a fair question: is this market worth the hassle? For investors equipped to do the work, the hassle is what creates the opportunity. A seller may value certainty, speed, discretion, the capacity to move a large position, or a clean solution to a complicated ownership problem. In a negotiated market, price reflects more than the last visible trade; it can also reflect the buyer’s ability to meet those real-world needs. The payoff for all of this work is a parallel route into companies creating substantial value before public markets see them – without waiting for the company to raise new capital or competing for an allocation in a primary round, and on terms that can reward a buyer willing to provide liquidity when it is genuinely needed.

Informed participation depends on keeping the market’s essential distinctions clear: economic exposure vs. verifiable ownership; displayed prices vs. genuine price discovery; access to an asset vs. access to the information required to value it.

Those distinctions are not academic. They reflect a market built deliberately over nearly five decades by issuers, institutional buyers, specialist firms, and regulators in response to real and lasting constraints.

Private secondaries are not an immature version of public markets waiting to become more transparent, liquid, or democratic. Their defining conditions are structural, intentional, and durable.

A clear view of the asset class begins with those conditions. From there, the real work can begin.
