The greatest wealth creation in American capitalism now occurs before a company's stock is available to the public. Companies that once went public at $500 million valuations now remain private until they are worth $50 billion or more — a structural shift that has transferred the most explosive phase of corporate growth from public markets, where retail investors can participate, to private markets, where they cannot. When these companies finally conduct an initial public offering, the event that was once an invitation for public investors to share in future growth has become an exit event for the venture capitalists, employees, and institutional investors who captured that growth years earlier.
The Privatization of Growth
In 1999, the median technology company went public at a market capitalization of $152 million. By 2024, the median had risen to $2.3 billion. The shift is a direct consequence of the JOBS Act of 2012, which raised the shareholder threshold that triggers mandatory SEC registration from 500 holders of record to 2,000 holders (excluding employees). Before the JOBS Act, a company whose stock was held by more than 500 shareholders was required to file public financial statements — a regulatory trigger that effectively forced successful private companies to go public. The JOBS Act eliminated this trigger, allowing companies to remain private indefinitely while raising virtually unlimited capital from accredited investors and institutional funds.
The consequences are measurable. Amazon went public in 1997 at a $438 million valuation. An investor who bought shares at the IPO and held them through 2026 earned a return exceeding 200,000 percent. Facebook went public in 2012 at a $104 billion valuation. The same percentage of its total lifetime value creation had already occurred in private markets. Stripe, valued at over $90 billion in its most recent private funding round, has not gone public at all — and may not for years. The retail investor's access to Stripe's growth is zero.
The pattern is consistent across the technology sector. The companies that defined the last decade of wealth creation — Uber, Airbnb, Palantir, Snowflake, DoorDash — all reached multi-billion-dollar valuations before their IPOs. The IPO itself was not the beginning of the growth story. It was the climax.
How Secondary Markets Work
Secondary markets for private company shares have emerged to provide liquidity for employees and early investors who wish to sell their holdings before an IPO. Platforms such as Forge Global, EquityZen, and Nasdaq Private Market facilitate these transactions — matching sellers (typically former employees or early-stage investors) with buyers (typically institutional investors and accredited individuals with minimum net worth of $1 million or annual income of $200,000).
The mechanics differ fundamentally from public market trading. There is no continuous market with real-time pricing. Transactions are negotiated bilaterally, with the platform providing price discovery based on recent comparable sales, tender offer prices, and the company's most recent 409A valuation. Shares often carry transfer restrictions — the company's right of first refusal, board approval requirements, and contractual limitations on who may purchase — that limit liquidity and create illiquidity discounts of 10 to 30 percent relative to the implied valuation from the company's most recent primary fundraising round.
For the small number of retail investors who qualify as accredited, secondary market platforms offer pre-IPO access at valuations below the eventual IPO price. But the minimum investment is typically $50,000 to $100,000 per position, the holding period is indefinite (there is no guarantee the company will ever go public), and the information available for due diligence is a fraction of what SEC-registered companies are required to disclose.
What a Modern IPO Actually Represents
The traditional narrative of the IPO — a young company raising capital from the public to fund its growth — has been superseded by a reality in which the IPO serves four purposes, none of which is primarily about funding growth.
First, the IPO provides liquidity for early investors. Venture capital funds operate on ten-year life cycles. A fund that invested in a company's Series A round in 2016 needs to return capital to its limited partners by 2026. The IPO creates a public market in which those early shares can be sold.
Second, the IPO provides liquidity for employees. Engineers, executives, and early hires who received stock options or restricted stock units as compensation need a liquid market in which to convert their paper wealth into cash. The IPO — specifically, the lock-up expiration 180 days after the IPO — is the event that unlocks employee liquidity.
Third, the IPO establishes a publicly quoted currency that the company can use for acquisitions. A private company that acquires another company must pay in cash. A public company can pay in stock — issuing new shares to the target's shareholders — at a valuation set by the public market.
Fourth, the IPO satisfies the SEC reporting requirements that come with broad share ownership — requirements that the company may have been approaching anyway as its shareholder base expanded through secondary market transactions.
Capital raising — the ostensible purpose of the IPO — is often a secondary consideration. Many recent IPOs have raised modest amounts relative to the company's total valuation, and some have been structured as direct listings that raise no new capital at all.
The Structural Inequality and the Path Forward
The privatization of growth has created a two-tier capital market in which institutional and accredited investors access the highest-returning phase of corporate development, while retail investors are offered the residual. This is not a conspiracy. It is the structural consequence of regulatory design — specifically, the accredited investor standard that restricts private market participation to individuals meeting income and net worth thresholds established in 1982 and never adjusted for inflation.
The SEC has explored expanding the accredited investor definition to include individuals with professional certifications or demonstrated financial literacy, but no comprehensive reform has been enacted. Until it is, the retail investor's access to pre-IPO growth remains limited to the secondary market platforms that serve accredited investors and to the handful of registered funds — typically closed-end funds or interval funds — that hold private company shares within a public market wrapper.
The investor who understands what a modern IPO represents — an exit, not an entrance — approaches new public offerings with a fundamentally different set of expectations than the investor who still believes the IPO is an invitation to participate in a company's growth story. The growth already happened. The question for the public market investor is whether sufficient growth remains to justify the valuation at which the insiders are selling.
