Federal prosecutors in Manhattan charged the founder of Linqto this week with orchestrating a $450 million fraud against more than 13,000 investors who came to the platform for access to pre-IPO shares of private companies. William Sarris, 75, who founded the company and ran it as chief executive for 14 years, faces six counts including securities fraud, wire fraud, broker-dealer fraud, and conspiracy. His one-time president and successor, Joseph Endoso, 66, has already pleaded guilty and is cooperating. Sarris maintains his innocence, and the case will be decided in court. But the allegations describe something worth studying regardless of the verdict, because they point at a structural weakness in the private-share market that does not depend on any one executive's honesty.
The charge at the center of the case is not that Linqto sold fake shares. It is that Linqto sold shares at prices it invented, while telling customers those prices came from a market. Prosecutors describe an internal joke in which the pricing pitch was "fake it till you make it, baby," with the actual prices set by what the founder allegedly called a "little Wizard of Oz" behind the screen. Allegedly. But the joke would not have been possible without a real problem: a share of a private company has no exchange, no ticker, and no closing price. Someone has to name a number. The investor on the other side of the screen has no way to know whether that number is a market or a markup.
Private shares have no price until someone sets one
That absence of price discovery is the uncomfortable foundation of the entire pre-IPO investing boom. A public stock is continuously repriced by millions of trades. A private share is repriced when a funding round closes, and even then the price reflects what one set of investors paid for a specific class of shares at a specific moment, often with terms attached that are invisible to the retail buyer of a sliver of the same company. Platforms like Linqto exist precisely to bridge that gap, aggregating demand from smaller investors and parceling out shares of companies like Anthropic, Ripple, and SpaceX. The platform's whole value proposition is access. The indictment describes what access looked like on the inside.
According to prosecutors, from 2020 through 2025 Sarris allegedly exploited investors' difficulty valuing pre-IPO companies by manufacturing false scarcity, showing investments as sold out when shares remained available, and charging markups with a median around 60 percent and some transactions exceeding 200 percent. Customers were assured they were buying at algorithm-based "market" prices. In early 2025, when revenue pressure mounted, the company allegedly sold some securities allocated to clients. Two months later Linqto suspended operations, and by July 2025 it was in Chapter 11. These are allegations, and Sarris's lawyer says his client is innocent and intends to fight. But the sequence the prosecutors describe has a logic that the industry should sit with: when the platform is the only source of the price, the temptation to let the price serve the platform is permanent, not exceptional.
The markup was the business model
The most uncomfortable detail in the charging papers is the median. A 60 percent markup is not a rounding error or a convenience fee. It is a second business model hidden inside the first. If a customer believes they are buying a share of SpaceX worth $100 and the platform paid $62, the platform has just earned 38 points before the customer has earned anything, and the customer cannot detect it, because there is no public quote against which to check. High double-digit markups can only persist in a market where the buyer cannot shop the price. That is what private shares are: a market where the buyer cannot shop the price. The allegation is that Linqto monetized that opacity. The deeper lesson is that opacity can be monetized by design, and that investors should treat any platform that is both the seller and the pricing authority with the same suspicion they would bring to a casino that also keeps score.
The aftermath shows what the investors were left holding. A Texas bankruptcy judge approved a reorganization plan in February offering customers a choice between a liquidating fund and a closed-end fund holding the private shares. A liquidating fund sells at whatever the market will bear; a closed-end fund asks investors to wait years for private positions to resolve. Neither outcome resembles the access that was sold. The draw was Anthropic, Ripple, SpaceX, the companies of the moment. The delivery was a choice between a liquidation and a long wait, with the original markup already spent.
The retailization of private markets set the stage
The 13,000 number matters. Private shares were once reserved for venture funds and accredited insiders who could price them because they sat on boards or syndicated rounds. The past decade democratized the entry ticket well ahead of the information. Platforms lowered minimums, promoted fractional stakes, and marketed the private technology giants as something a working professional could finally own before the IPO. That pitch was not fraudulent. It was also incomplete, because the average customer gained access without gaining any of the instruments that make private investing work for institutions: valuation data, board seats, liquidation preferences, and lawyers who read the purchase agreement. What institutions buy with diligence, retail customers were asked to buy with trust. The Linqto allegations describe where that trust could be spent.
The timing compounded it. Between 2020 and 2025 the private markets experienced their longest sustained boom in history, with companies like the ones Linqto featured staying private far longer than any prior generation. The longer a company stays private, the more secondary-market trading it attracts, and the more a platform can tell a plausible story about algorithmic pricing, because by then the company has raised many rounds and there are many data points to fit a curve to. The indictment's central claim is that the algorithm was theater. Even where a platform's pricing is honest, though, the customer is still buying a secondary-market price that no regulator has blessed and no exchange has touched. The structural lesson survives every verdict: the private markets got bigger and more retail-facing faster than their pricing infrastructure did.
The only honest number is the one somebody negotiated
There is a genuine price in every pre-IPO story, and it is the price of the last primary funding round. That number was negotiated between the company and an investor who performed diligence, received contractual rights, and bought at the company's own valuation. Everything after that is someone else's number. A secondary share can legitimately trade above the round price if demand has grown, or below it if the last round was rich. But the moment a platform quotes its own secondary price, the customer is not buying the company's valuation at all. The customer is buying the platform's spread over whatever it paid, adjusted for its own inventory pressure. The January 2025 allegation, that the company sold securities allocated to clients to hit revenue targets, is what inventory pressure looks like from the inside. When the platform needs revenue, the inventory moves, and the customer discovers that "their" shares were never quite theirs until the platform's books said so.
None of this means retail investors should be locked out of private companies. It means the entry ticket has to include the same information the institutions get: what was paid, when, and through what structure. Some platforms already disclose this. The ones that do not are pricing the product with the customer's ignorance as an input.
What changes after Linqto
The response from regulators is already visible. The SEC's examination program has reportedly begun asking registered investment advisers to verify that claimed pre-IPO holdings exist, a direct answer to the question of what customers were shown. Criminal cooperation from a former CEO, which is part of this case, is the kind of fact that tends to reach other executives at other platforms. And the economics of the platforms themselves will shift, because verification costs money and disclosure invites comparison. A platform that must prove it owns the shares it sold, at the price it says, is a platform with a thinner margin. That is not a bug in the reform. It is the point.
For investors, the practical takeaways are narrow and durable. Ask whose name is on the security, and whether the position sits in a special purpose vehicle whose documents you can read. Ask what the platform paid, not just what it is asking. Treat "sold out" and "limited allocation" as marketing language unless the platform will disclose the source of the shares and the date of the purchase. And remember that in a market without a public quote, the only person who can tell you the price is the person selling to you. The Linqto case is about what prosecutors say one man did with that power. The structural question is why any investor should have to take that person's word.
