Somebody just fleeced Wall Street for $100 million

Somebody just fleeced Wall Street for $100 million dollars. Nobody knows who they are and now Wall Street is trying to hunt them down. So here's what happened. The story starts with two Chinese companies you've probably never heard of. The first is called Futu Holdings and the second is called Tiger Brokers. Both are basically Chinese versions of Robin Hood. They let regular Chinese investors trade US stocks from their phones. These apps are wildly popular, but the Chinese government wasn't happy with them. You see China has strict capital controls that limits the amount of money that can leave the country. And Futu and Tiger were making it very, very easy for money to leave and buy American stocks. For a long time, the government looked the other way. But as the apps kept growing and getting more popular, regulators started seeing them as a real problem. Keep that in mind because it's important context for what comes next. So starting around May 2026, someone or a group of people began buying massive amounts of put options on Tiger and Futu. Put options, if you don't know what a put option is, it's essentially a bet that a stock will go down. If the stock crashes, you make a lot of money. But these weren't just any puts that the traders were buying. They were short-dated out-of-the-money puts, which are essentially lottery tickets. They would only pay off if the stocks crashed dramatically over the course of just a few days. Otherwise, they'd expire worthless. So over about two weeks, these mystery traders bought about 200,000 of these puts. They spent $12 million total. A huge bet that these two Chinese brokerages have a very bad day. Now, Wall Street comes in. While the mystery traders were buying put options, someone had to sell those options to them. After all, for every buyer, there has to be a seller. As it turns out, the seller for a lot of these put options was Susquehanna Investment Group, a Pennsylvania-based company founded by Jeff Yass, who's worth around $92 billion. So they were on the other side of a lot of these trades, selling the put options to the mystery traders. But unlike the traders, Susquehanna wasn't betting on the direction of the stocks. They're called a market maker. The middleman in markets. If someone wants to buy an option, Susquehanna sells it to them. If someone wants to sell an option, Susquehanna buys it from them. They stand in the middle of all these trades and collect a small profit from each one. It's a great business model when it works because usually some people wanna buy, some people wanna sell, and it all evens out. But the model runs into problems when the other side knows something that the market maker doesn't. Which brings us back to Futu and Tiger. On May 22nd, 2026, the Chinese government, out of nowhere, dropped a bombshell. Eight different agencies released a joint statement announcing a crackdown on cross-border brokerages. They specifically named Futu and Tiger and said these companies had been operating illegally in China. The market reaction was brutal. Futu got hit with a fine of about $273 million and its stock crashed. The founder, a guy named Leaf Lee, lost $1.7 billion of his personal fortune in just a single day. Tiger stock crashed too. On the other hand, all of those mystery traders bought a few days earlier went through the roof. That $12 million bet turned into more than a hundred million dollars in profits, over 900%. Meanwhile, Susquehanna, sitting on the other side, ate a loss of $70 million. The company was furious and immediately claimed that the traders had done something nefarious. So last Monday, the company filed a lawsuit in federal court against the traders. The problem is, they don't exactly know who they're suing. So they asked the court to force the brokers that the traders used to hand over the names of everyone who bought a put. A judge granted the order this week. He froze the accounts that made the trades and gave Susquehanna the green light to subpoena the brokers and unmask the traders. The SEC has also opened its own investigation. Now, at this point, you might be wondering what the problem even is. Wasn't this just a good trade? What gives Susquehanna the right to sue these traders? Well, it's true that Susquehanna doesn't actually know for a fact that anything nefarious actually happened. They don't have hard evidence like emails or a whistleblower. What they do have, though, is a pattern. Their argument goes like this: Market makers deal with unpredictable news all the time. Companies announce good earnings results, bad earnings results, mergers and acquisitions, all kinds of stuff that move stock prices significantly. And market makers mostly come out that fine because it all evens out. But what killed Susquehanna here is the trades were massively one-sided. And their argument is this couldn't have happened by accident. If the Chinese crackdown had been a total surprise, there's no reason anyone would have built that type of position. Nobody randomly bets $12 million on short-dated put options that only pay off if something really bad happens in just a few days. Susquehanna is trying to make the case that the pattern is so specific and so well-timed that insider information is the only explanation that fits. Now, as for who the leaker is, the company's own theory that it laid out in the lawsuit is that it had to be one of two groups. Either Chinese regulators who were involved in planning the crackdown, or employees at Futu and Tiger that somehow got wind of it. Perhaps not coincidentally, the mystery traders used Futu and Tiger to place their trades. So what do you guys think? Did somebody in China tip these traders off, or did they just read the political winds better than everyone else? Let me know in the comments for more insights on the economy and investing.
