Recently, a video by the overseas financial channel Casual Finance, The Stock Market Is Being Used as a Dumping Ground, has circulated widely online. It begins with a chart: putting the first-day market caps of US tech companies side by side reveals two vastly contrasting bars. The bar on the left represents the past half-century. Over the forty-five years from the dawn of the personal computer in 1980 to today, the cumulative first-day IPO market cap of all US tech companies totaled only about $4.1 trillion. That includes thousands of companies across different eras, as well as the entire dot-com bubble around the turn of the millennium.
The bar on the right stands right beside it, completely overshadowing the left. It doesn’t span forty-five years, nor does it take thousands of companies—just three names everyone talks about daily: SpaceX, Anthropic, and OpenAI. Based on the public valuations and rumored target prices compiled in the video, these three alone add up to around $5.2 trillion.
This scale is larger than the combined first-day market capitalization of every newly listed company in the US tech sector over the past forty-five years. Putting these two numbers side by side has prompted many to rethink the public markets: where capital flows and who gets to participate operate under rules that are no longer what they used to be. But the more practical questions are: how did this shift happen step by step, and what is actually left for ordinary investors?
In many people’s memory, tech companies ringing the bell on the public market usually did so when they were still young, or even just getting started. A classic example is Amazon in 1997. Jeff Bezos had been running his online bookstore for just three years; losses were steep, and cash in the bank was dwindling. To keep the company alive, he needed to issue stock to the general public to raise working capital. Amazon was remarkably candid in its prospectus back then, stating that the proceeds had no specific intended use and were primarily meant to cover ongoing losses from day-to-day operations. That year, Amazon went public at a valuation of $430 million. Had someone bought $1,000 worth of Amazon shares back then and held them until today, that investment would now be worth over $3 million.
Back then, ordinary retail investors in the secondary market had the chance to ride along with a great company’s growth primarily because three factors forced young companies onto the stock exchanges. The first reason was a lack of money. A young company often required massive capital injections to expand quickly, but in those days, beyond issuing public equity to everyday retail investors, there was no other way to absorb such immense sums of capital all at once.
The second constraint came from regulatory rules. In 1964, an amendment to the US Securities Exchange Act added a provision: once a private company reached 500 shareholders of record, it was legally required to publish quarterly reports, annual reports, and key operational disclosures to the world, just like a public company. Because all trade secrets would inevitably have to be disclosed anyway, many founders simply went public, picking up public market liquidity along the way. Microsoft, Google, and Facebook all chose the public markets after their shareholder counts approached 500. Mark Zuckerberg publicly stated at the time that he did not want to go public so early, believing that staying private was better for the company’s long-term health. Unfortunately, this cap left Zuckerberg with no way to delay any further.
The third constraint came from liquidity needs among early employees and angel investors. Early startup employees and angel investors held large amounts of stock options and common shares, but prior to an IPO, there was no public trading market for these equities, making them difficult to cash out. To reward employees’ hard work and deliver cash returns to early-stage investment firms, going public was virtually the only option.
A shortage of cash, mandatory public reporting, and internal pressure for liquidity—these three factors combined to push young startups into going public early. The objective result of these early IPOs was that a company’s fastest-growing golden years were left for everyone in the secondary market to share.
Over the past thirty years, the three forces that once drove companies to go public early have broken down one after another through a gradual evolution of regulations and market tools. What changed first was the source of capital. In the early days, private companies could only raise funds from a very limited number of backers, but the National Securities Markets Improvement Act of 1996 broke through that limitation. The legislation eliminated the rigid cap that previously restricted private funds to no more than 100 investors, provided that the contributors qualified as professional institutions or qualified purchasers. From then on, large pension funds, university endowments, hedge funds, and mutual funds—which historically traded only in public secondary markets—began investing heavily in private company equity at scale. Startups no longer had to embark on public roadshows to raise expansion capital from the general public; institutional capital knocking at their door was already abundant, and the public market ceased to be the only route to securing massive sums.
What changed next was the shareholder threshold triggering mandatory public disclosure. In 2012, the US passed the JOBS Act, which introduced two pivotal changes: first, it raised the shareholder threshold for mandatory financial reporting from 500 to 2,000; second, it explicitly exempted employees who received shares through employee compensation programs from this threshold. This change eliminated the regulatory pressure that had most frequently forced unicorns to go public. Even if a company hired thousands of engineers receiving equity incentives, as long as its shareholder structure complied with the rules, it could remain private indefinitely—without having to reveal its actual operational metrics, profitability, or strategic intentions to the outside world.
Finally, it addressed the issue of internal employees wanting liquidity. Once the shareholder cap was relaxed, tender offers became increasingly seamless. Companies didn’t even need to list on an exchange; they could simply organize periodic internal secondary share sales, allowing designated external mega-funds to purchase shares directly from employees and early investors seeking liquidity at agreed-upon prices. The video likens this to a company hosting a yard sale for employee shares in its own backyard. Employees get cold, hard cash, yet the equity never lands in the public markets, and core control remains firmly in management’s hands.
Stripe, the financial infrastructure company founded in 2010, is a prime example of this new path. Throughout its more than a decade of existence, it has consistently avoided going public, using internal tender offers to provide liquidity to its workforce. According to the video, over the past two years alone, its internal valuation surged by roughly $100 billion, yet ordinary retail investors in the secondary market could not buy a single share. When asked when the company might formally go public, the co-founder calmly replied that they might consider it at some point in the future.
This means that all three pillars that once propelled a tech company to ring the opening bell have collapsed. It is now entirely possible for a tech enterprise to spend its entire lifecycle without ever going public, growing into a titan worth hundreds of billions—or even trillions—of dollars.
Institutional research cited in the video notes that for typical tech companies that went public over a decade ago, roughly 80% of their value growth occurred after listing on the exchange; for typical companies in recent years, however, more than half of their valuation growth had already been realized during their private phase before ever reaching an IPO.
When the public market shifts from a starting line to a finish line, the game rules in the secondary market undergo a fundamental transformation. Why so many people love early-stage investing is because of its inherent asymmetry: if you fail, downside is capped—at most, you lose your initial principal; but if the bet is right, returns can be tens or hundreds of times your original investment. When Amazon went public at $430 million, it offered ordinary investors exactly that kind of asymmetric payoff. Buyers certainly had to bear the risk that this fledgling company might go bust and drop to zero, but so long as it rode the rising tide of e-commerce, it could deliver outsized, asymmetric returns on a modest stake.
Yet if you imagine a behemoth like SpaceX approaching a $1.8 trillion valuation entering the public market, the scenario looks completely different. The video runs through a thought experiment: if secondary market investors today hoped to achieve the kind of return multiple Amazon delivered back then, the company’s market cap would have to balloon to an absurd figure—not only exceeding ten times the total personal wealth in the entire world, but even if one merely wished for a 100x return, its scale would still exceed the combined market cap of every publicly listed company on Earth today.
Once a company reaches this scale, multiplying its valuation many times over becomes mathematically unrealistic. Its core conclusion is that buying into these mature giants today still leaves investors in an asymmetric gamble—only this time, the asymmetry is flipped in reverse. Paying a steep admission price and bearing substantial downside risk from sky-high valuations, all in exchange for relatively capped upside. This is no longer risking small capital for massive payoffs; it is more like standing at the edge of a cliff, putting up big money just to chase a modest fraction in return.
The video coins a label for this phenomenon, arguing that the stock market is becoming a dumping ground for private equity: insiders pocket the most lucrative phase for themselves, leaving only the leftovers for the secondary market. It is a punchy narrative that easily resonates with retail investors. Yet, it seems to me that this only settles half the ledger.
The core argument of the video rests almost entirely on highlighting the multiples of upside that ordinary investors have missed out on. For instance, it repeatedly contrasts Amazon’s thousand-fold return back then with the ceiling on multiples for today’s giants, leveraging that dramatic disparity to evoke a keen sense of deprivation. But investing is a two-way street; looking only at returns without examining risk is incomplete. The video points out the upside ordinary investors have lost, but fails to examine whether the downside risk faced by those investors has undergone a corresponding shift.
Following business intuition one step further naturally prompts the question: as tech companies have shifted from going public after three years to waiting more than a decade, what does the real probability distribution look like for retail investors? Are the extreme outcomes on both ends—windfall gains and catastrophic wipeouts—both narrowing? Or has the chance of a 1,000x gain vanished while the risk of falling off a cliff remains entirely intact? Without working through this arithmetic, concluding that the secondary market has become an unequivocal victim simply because upside multiples have shrunk remains logically incomplete.
To understand this shift, one must disentangle the two primary drivers of stock performance: purchase price and business maturity. First, consider the impact of the purchase price. Assuming the same company with identical business prospects, buying in at a $1 billion valuation versus a $100 billion valuation yields vastly different outcomes: the higher the entry price, the lower the future multiple potential; moreover, if the valuation is stretched too far, any tightening in macroeconomic liquidity or shortfall in expectations will trigger a sharp drawdown in valuation. Looking solely at purchase price, entering later at higher prices undeniably reduces returns and magnifies risk.
In reality, however, an opposing force is also at work: the company’s business maturity. A three-year-old startup operating out of a garage might find that no one buys its product, its cash runway could dry up within six months, and its management team might fall apart overnight—the probability of total operational failure and liquidation is exceptionally high. Of the dot-com companies that emerged alongside Amazon back then, a large number of them simply did not survive. By contrast, mature enterprises that have spent over a decade grinding through private markets, generating billions or tens of billions in annual revenue, and establishing deep global moats face a substantially lower probability of complete operational collapse or liquidation.
Looking at these two forces together reveals that reality is rarely as simple as a black-and-white verdict. When a company goes public after more than a decade with significant maturity, its business model is already proven, and the existential risk of a total wipeout is indeed vastly reduced; at the same time, because the initial pricing is already stretched to the limit, the room for outsized future returns is heavily compressed. Under these circumstances, the extreme possibilities on both ends—windfall gains and catastrophic wipeouts—are actually narrowing simultaneously.
The most dangerous scenario arises when a company has spent more than a decade in private markets yet still lacks healthy organic cash flow—relying instead on massive external rounds to subsidize its burn—only to be pushed onto the public market amid universal fanfare at a trillion-dollar valuation that borrows heavily against the future. In that case, the game completely breaks down. Investors buying into such a company end up paying a premium reserved for mature giants while holding a fragile asset as prone to bleeding cash as an early-stage startup.
When calculating risk and return, another calibration of scale is critical. In the mathematical logic of investing, a 1,000x gain and a 1/1,000th decline are not symmetrical in terms of dollar profits and losses. No matter how high the purchase price is pushed, an investor’s dollar loss is always strictly capped by their initial principal, whereas upside returns are theoretically uncapped. When evaluating this market shift, one cannot conflate raw percentage or multiple changes with actual dollar gains and losses in an account.
With the fastest-growing chapter no longer shared with the public, the secondary market faces a trade-off that requires careful calculation: whether the massive upside surrendered is truly worth the price tag on the table in exchange for business certainty and survival probability.
