Venture capital's fund structures were not built for the trillion-dollar era

THE VENTURE CAPITAL industry has a compounding problem — and it is not the kind taught in business school. Nvidia needed three decades to reach a $1 trillion market capitalization, then barely two years to quintuple it. The trajectory is a case study in exponential growth, the sort of outcome every investor fantasizes about. It is also precisely the sort of outcome that venture capital, as currently constructed, is structurally incapable of capturing.

A reductionist framework for venture investing reduces each opportunity to four variables: the size of the prize, the probability of success, the cost of the investment, and the time to exit. Most practitioners are competent at estimating costs and reasonably calibrated on near-term results. They tend to overestimate their probability of success — an occupational hazard of selection bias, since the more successful one's career, the rosier the outlook. But the truly catastrophic miscalibration concerns long-duration bets, where investors are, in the words of one Sequoia partner, "wonderfully off about the size of the prize." Fifteen years ago, a few hundred billion dollars in market capitalization was considered the ceiling for a technology company. Today, multiple firms sit comfortably above $2 trillion. The error was not a failure of imagination so much as innumeracy about compounding: a company worth a few hundred billion that grows at 10% annually will, by unremarkable arithmetic, be worth a few trillion within fifteen years.

Exit, pursued by returns

Yet knowing this and profiting from it are very different things. The institutional rhythms of venture capital — ten-year fund lives, quarterly reporting to limited partners, the relentless pressure to mark and distribute — conspire against the kind of multi-decade holding that trillion-dollar trajectories demand. A seed investment that blossoms into a $1 billion company in a decade might, in two decades, be worth $10–100 billion; in three, $100 billion to $1 trillion. The math is seductive. The governance is brutal. GPs must return capital to LPs; LPs must report to their own beneficiaries; and everyone, at every link in the chain, has a fiduciary incentive to take money off the table rather than let it ride.
