Venture capital is in a strange place. On the way in, it looks like a boom: AI companies raising mega rounds at record valuations, capital pouring into the asset class. On the way out, it looks like a downturn: distributions near decade lows, LPs waiting years for DPI, an exit market that never seems to reopen. Most of the industry treats the second half as a cycle to be waited out. I think that's a misdiagnosis.
In 1986, Microsoft went public at a valuation of roughly half a billion dollars. Everything that followed — the climb to a market capitalization now measured in the trillions — happened in the public markets, where any investor could participate. Amazon listed in 1997 at a $438 million market cap, three years after it was founded.
Now consider SpaceX, which stayed private until it was worth roughly $2 trillion. Or Stripe, OpenAI, Anduril, and dozens of others operating at a scale that would have made them large-cap public companies in any previous era. The appreciation that used to happen on the NYSE and Nasdaq now happens on private cap tables.
This is not a temporary condition waiting for the IPO window to "reopen." It is a structural change in how companies grow, and most of the venture industry is still organized as if it never happened.
The chart below makes the point visually: valuation at IPO for landmark venture-backed companies, from Microsoft in 1986 to SpaceX today. Note that the vertical axis is logarithmic — each gridline represents a tenfold increase. On a linear scale, Microsoft, Amazon, and even Google would be invisible dots on the floor of the chart next to SpaceX. Even with the scale compressed this aggressively, the line still climbs relentlessly. Companies are arriving at the public markets three to four orders of magnitude larger than they did a generation ago.
In the 1980s and 1990s, the median venture-backed technology company went public four to six years after founding. Today the median age at IPO is eleven to thirteen years, and the median time from first venture financing to exit has roughly doubled.
Meanwhile, the number of listed companies in the US has fallen by nearly half since 1996, from about 8,000 to a little over 4,000.
The reasons are well understood. The regulatory and reporting burden of being public grew substantially after Sarbanes-Oxley. Small-cap research coverage collapsed. The effective revenue threshold for a credible technology IPO went from around $30 million in the 1990s to several hundred million today. A CEO of one of our portfolio companies, a business doing half a billion dollars in revenue, put it plainly: it is simply easier to be a private company now. The standards for public listing went up, and they have stayed up.
At the same time, private capital expanded to fill the gap. A decade ago there were a few dozen unicorns; today there are well over a thousand. Companies can raise IPO-scale rounds from crossover funds, sovereign wealth, and mega-funds without ever filing an S-1.
Most of the conversation about this shift is framed as a problem. LPs point to distributions sitting near decade lows as a share of NAV. GPs apologize for fund lives stretching past fifteen years. And to be fair, the frustration is grounded in something real: the standard venture fund is a ten-year vehicle, designed in an era when the median company exited in six.
But it's worth remembering that funds routinely ran fifteen or sixteen years even before this trend fully took hold. The ten-year fund was always more of a legal convention than an accurate description of how venture actually works. What's changed is that the gap between the structure and the reality is now too large to paper over with extensions.
Here is what the complaints miss. If companies now compound from $1 billion to $50 billion or $500 billion while private, then the years everyone is lamenting are precisely the years when the most value is created. The appreciation didn't disappear. It moved. Public market investors captured Microsoft's climb from $500 million to $4 trillion. Private investors are capturing the equivalent climb today — but only the ones positioned to stay in, buy more, and hold through it.
The largest firms figured this out first. That is a big part of why venture fundraising has concentrated so dramatically, with a small number of firms raising mega funds and evolving into asset gatherers: they are building permanent exposure to companies that will stay private at enormous scale. Whatever you think of that model, it is a rational response to the shift.
For firms like ours, the shift widens the opportunity rather than narrowing it. PROOF's strategy is built around co-investing alongside early-stage funds that hold pro rata rights in breakout companies but lack the capital to exercise them. When companies stayed private for six years, those rights came up two or three times. When companies stay private for fifteen, the same rights come up round after round, at larger check sizes, in companies whose trajectories are far better understood. Longer private lives mean more pro rata opportunity, not less.
The industry is already improvising. The secondaries market set a record above $150 billion in annual volume, and continuation vehicles, once a private equity tool, are now being used by established venture firms to hold their best companies past the life of the original fund. Structured tenders, strip sales, and NAV-based solutions are giving GPs ways to return capital without forcing premature exits.
These are useful tools, but they are patches on a structure built for a different era. The more interesting question is what fund formation looks like when it's designed for the world as it is. That likely means longer stated fund lives with honest expectations set at the outset. It means vehicles purpose-built to hold late-stage positions, including SPVs and dedicated late-stage pools that sit outside the traditional fund mandate. It may mean evergreen and hybrid structures for strategies where a fixed term never made sense. And it means treating secondary sales as a deliberate portfolio management discipline rather than an admission of failure.
Every structural shift in an industry creates two groups: those who redesign around it and those who keep operating the old model while conditions move against them. Firms that cling to structures built for six-year exits will spend the next decade selling their best positions early — often to the firms that adapted, at prices that reflect the seller's constraints rather than the asset's value.
Companies staying private longer is not a liquidity crisis. It is the largest migration of value creation in the history of the asset class, from public markets to private ones. The investors who treat it that way will own the next twenty years.
