The Prediction-Market Backlash: Wall Street, the Courts, and the New Lines Over a Wild West Bet

On 10 July 2026, two Wall Street institutions did something that would have looked absurd in 2019: they told their employees to stop placing bets on whether the Federal Reserve will cut rates in September, whether the prime minister of Japan will still be in office by Christmas, or whether a given senator will switch parties. Goldman Sachs has barred its staff from trading prediction-market contracts, with the prohibition extending to contracts tied to macroeconomic data and to geopolitics, according to the firm's internal guidance reported on 10 July.

Five years ago, the question "is this a security, a swap, a commodity, or a casino bet" would have drawn a blank from most compliance officers. By the second week of July 2026, the question has migrated from the trading desks of the world's most powerful investment bank to a state courthouse in New York, to the Federal Reserve's regulatory perimeter, and to the social feed of Michael Burry, the investor who made his name shorting the housing market in 2007. Burry believes prediction markets are currently exploiting regulatory loopholes and will eventually face oversight and taxation, he said in remarks carried on 11 July. The cracks are widening from every direction at once.

This is a story about what happens when a financial product arrives faster than the rules designed to govern it, and the regulators, the courts, and the incumbent banks each independently decide to draw a line. The product in question is the event-contract market: a class of exchange-traded instruments that pay out yes-or-no on a defined question, typically priced in cents between zero and one dollar. Kalshi and Polymarket run the headline venues in the United States; DraftKings runs a consumer-facing sports-adjacent book through its Flutter-owned rails; Coinbase and Crypto.com have built derivatives layers stacked on top. The market capitalisation is small by Wall Street standards. The cultural footprint is not.

A bank, a courtroom, a bedroom floor

Goldman Sachs's employee restriction, reported on the evening of 10 July, is more conservative than those adopted by some of its competitors, but it signals how the question is migrating up the seniority ladder. According to the report, the prohibition covers contracts tied to macroeconomic data and to geopolitics, the two categories where the bank appears to see the cleanest conflict between an employee's market knowledge and the integrity of the firm's research. The move follows similar guidance from a growing list of buy-side and sell-side firms. Compliance lawyers describe the underlying problem in plain terms: a Goldman analyst who trades a contract on whether the next CPI print will come in above consensus has effectively turned a non-public information regime into a tradable asset. The bank that prides itself on information advantages has decided that this particular advantage is one it does not want its staff to monetise.

In a separate move on the same day, New York state banned smart glasses in courthouses across more than 1,240 state, county, city, town and village courts. The official rationale is witness intimidation and the recording of sealed proceedings. The subtext, in the prediction-market era, is harder to ignore. Cameras-on-glass devices at the right moment can capture a juror's expression, a defendant's family member, or the price of a sealed settlement, and turn any of it into a fast-firing contract in under two seconds. The state is not regulating the market. It is regulating the means by which the market could be fed inputs that the rules of evidence say nobody should be looking at. The vendors of those glasses are not accused of wrongdoing; the courtroom is closed environment enough to invite pre-emptive caution.

Young adults, meanwhile, are increasingly watching all of this from inside their parents' houses. As of mid-2026, the share of Americans under 30 living with their parents had risen to roughly half of the cohort, compared with 37% in 2019, meaning the share still at home has grown by roughly a third in five years. That single cohort of now-29-year-olds was the first to grow up with smartphones in their pockets and prediction markets in their apps. The product is reaching them at a moment when they have spare bedroom ceilings, modest savings, and a feed full of influencers explaining the Kelly Criterion. It is reaching them faster than any savings vehicle that Wall Street has put in their path.

The loophole argument

The case for treating prediction markets as a regulated financial product rather than a gambling venue runs through a list of exemptions the operators say they qualify for. Event-contract venues argue that each contract is a swap, a commodity, or an exchange-traded product under some combination of Commodity Futures Trading Commission precedent, Securities and Exchange Commission no-action letters, or state-level derivatives definitions. The CFTC's 2024 green light for Kalshi to list election contracts under its own Designated Contract Market designation was the inflection point. Once political markets were a regulated product, the rest of the calendar followed: jobs reports, weather, sports outcomes (with carving-outs by state), and corporate events. The argument from the operators is straightforward. We have a federal regulator, a clearing structure, KYC procedures, and price transparency. We are not a casino, we are an exchange.

Burry's counter, delivered publicly this week, is that the structure of regulation is being captured faster than the substance of regulation is being written. Believing that prediction markets are currently exploiting regulatory loopholes and will eventually face oversight and taxation is not, on his reading, an argument that the markets will go away. It is an argument that they will be taxed, licensed, and constrained in ways the founders have not yet had to disclose to their limited partners. The "eventually" is doing the work. Burry's trade-as-told-to-the-public history is itself a case study in how an early position on a structural shift can be right in direction and punishing in timing.

Two structural counter-arguments complicate the prediction-market case. First, the academic literature on market efficiency, much of it generated inside US business schools since the 1970s, treats an efficient price as one that incorporates all available information at the moment of the bet. Prediction markets do that in narrow domains: the Iowa Electronic Markets on the 2008 presidential election produced estimates within a percentage point of the final vote share. The venues have, on isolated questions, beaten the polls. The second argument runs the other way. A market where a small number of informed participants can move a contract on a piece of non-public information about a corporate event is, structurally, an insider-trading marketplace with thinner walls than the equity exchanges, where the SEC has spent a century building walls. Whether those walls will be raised, lowered, or maintained through opacity will determine how much institutional capital the asset class eventually attracts.

An exchange or a casino, said both ways

The framing battle is not new. State attorneys general in more than a dozen US states have argued, in letters and lawsuits, that event contracts on sports outcomes constitute unlicensed gambling. The two largest consumer-facing sports books, Flutter-owned DraftKings and FanDuel, have developed their own prediction products that they argue sit cleanly inside the existing state-licensed sports-betting frameworks. The prediction-only exchanges counter that they are licensed as derivatives exchanges, not as sports books, and therefore not subject to state gambling law. The distinction is legal, but it is also a marketing war. A platform called an "exchange" attracts hedge-fund software. A platform called a "sports book" attracts casual bettors. The same eighteen-to-one odds can read as a market price or as a payout.

The newest wrinkle is the corporate floor. Goldman Sachs's employee prohibition arriving in the same week as a state-court camera ban points to a pattern: institutions do not wait for federal rule-making when their own exposure is immediate. The bank is not trying to police the world. It is trying to keep its own people from sitting on information that would make their personal bets look like professional research. The state is not trying to regulate the prediction market. It is trying to keep a recording device out of a room where the inputs to a market can be collected at speed. Each regulator is solving for a different slice, and the slices are not yet knit into a coherent whole.

This is also where the political economy gets uncomfortable. Prediction markets on election outcomes in the United States spent 2024 under close scrutiny. The platforms were licensed. The trades were settled. The integrity of the result was not, in any litigated case, found compromised. But the political energy around the question has not dissipated. A market that prices the probability of a senator switching parties, or of a prime minister surviving a confidence vote, is a market that monetises political instability. The first round of academic papers on the topic is now in working-paper circulation. The second round, treating event contracts as a leading indicator of political risk, is being written by the kind of researchers whose work eventually informs sovereign-debt pricing.

The crypto-money homecoming

A second pattern sits underneath the first. The infrastructure of the largest prediction venues is increasingly built on rails that look more like crypto markets than like CME futures. Polymarket settles contracts on a blockchain. Kalshi is fiat-settled but partners with a number of custodial wallets. The product reaches young investors, who already hold their dollars inside a Coinbase or a Robinhood account, through an interface that looks like a token swap. The flow of regulatory pressure on US retail crypto in 2023 to 2025 created the road. The flow of capital looking for low-fee, high-velocity venues populated the road. Prediction markets did not invent the rails. They rode them.

That is also where the geopolitical exemption sits. The United States loosened export restrictions for the United Arab Emirates earlier in 2026, a decision that opens semiconductor and AI-tooling flows into Gulf sovereign funds, several of which have written equity tickets into the same prediction-market venues that raised venture rounds in 2023 and 2024. The capital is now global. A no-action letter from the SEC in Washington does not reach a sovereign wealth fund that treats the contract as a digital-asset position. The venue in Abu Dhabi that lists a contract on the US election is unlikely to ask the CFTC for permission.

The shape of the next twelve months

Three dates sit on the calendar. First, the CFTC's anticipated 2026 rule-making on event-contract categories outside its existing DCM framework, expected by year-end, will test how aggressively the regulator is willing to police operators that have already built scale under 2024's permission. Second, the SEC's review of whether at least a portion of event contracts should be reclassified as securities will run in parallel. Third, the next election cycle will produce the first major stress test of whether the politically protected markets remain politically protected under a new administration.

Each of those moments is also a moment when the bank-trading bans will thicken, when state attorneys general will file new letters, and when a Bloomberg or Financial Times reporter will publish a long piece about how a 22-year-old turned twelve thousand dollars into a million by reading a Bloomberg terminal more attentively than a senior trader. The product is not going away. Burry is right about the trajectory; he is also right that the trajectory passes through regulation that the operators have so far avoided drafting themselves. The bank restriction, the courtroom restriction, the living-with-parents demographic, and the UAE capital flow are not separate stories. They are the perimeter of a new asset class being walked by four different constituencies with four different rulebooks in their heads.

What remains contested is whether the next round of rules lands as a turf expansion, where the prediction markets absorb the rules the same way they absorbed the CFTC's 2024 election-contract license, or as a turf compression, where the categories that survive are the categories that look least like gambling and most like a thin-margin financial exchange. The founders of the venues have a strong financial interest in the former outcome. The state attorneys general and incumbent exchanges have a strong interest in the latter. The customers, who are largely under 30 and increasingly living in their parents' houses, are not yet a constituency that either side is courting directly. That will change well before the rule-making does.
