Who Decides What Counts as a Market

You​‌​​​​‌‌​‌​​​​​‌​‌​​​​‌‌​‌​​‌​​​​‌​​​‌​‌​​‌‌​​‌​​​‌‌​‌​‌​​‌‌​‌‌​ think a prediction market is a market. A crowd prices an outcome, the best information wins, no house sets the line. That is the story. The structure is that whether the thing you are trading counts as a market at all is a decision someone makes about you, and four different parties are fighting right now over who gets to make it.

Here is what that means for you before we get to how it works. The outcome you are allowed to price is not set by the crowd. It is set upstream, by whoever wins the right to define the venue you are pricing it on. The crowd operates inside a permission it did not grant itself. When the permission moves, the market moves with it, and you find out after the fact.

So the interesting question was never who is the biggest prediction market. Kalshi is reportedly in talks near a 40 billion dollar valuation, Polymarket closed a round earlier this year around 15 billion and is reported to be raising toward more. Those numbers are real and they do not tell you anything about power. The number that tells you about power is the one you cannot see: the count of parties who can decide, unilaterally, that a given contract is no longer allowed to exist. That number is four, and they do not agree.

// The four decisions stacked on top of each other

Start with the mechanism, because the fight only makes sense once you see the machine. A market for an event does not become legal by being popular. It becomes legal through a filing.

A federally licensed exchange, a Designated Contract Market, lists an event contract by self-certifying it under the Commodity Exchange Act. The exchange files the terms and an analysis of why the contract complies, and it can list the next business day. No regulator signs off in advance. Read that again, because it is the first decision and almost nobody names it: the party who decides, first, that your bet is a legitimate financial instrument is the company selling it to you. The presumption of legality runs in their favor by default.

The second decision is a veto, and it belongs to the CFTC. Buried in the statute is a special rule for event contracts: the Commission may determine that a contract involving certain enumerated activities is contrary to the public interest, and then it cannot be listed. The enumerated list is specific. Activity unlawful under any federal or state law. Terrorism. Assassination. War. Gaming. And a catch-all: other similar activity the Commission decides, by rule, is contrary to the public interest. That rule is numbered 40.11. When you hear people argue about whether a sports contract is "gaming," this is what they are arguing about. They are arguing about which words in that list your bet falls under.

The third decision belongs to the states. Every state has a gambling regulator, and a sports outcome traded for money looks, to that regulator, exactly like the thing it exists to license. So the states send cease-and-desist letters and file suits. Their claim is simple: this is betting, betting is ours, a federal derivatives label does not change what it is.

The fourth decision belongs to the courts, and it comes down to a single word. Are these contracts "swaps"? If they are swaps, the CFTC has exclusive jurisdiction and the states are preempted, meaning the federal definition wins and the state gambling law is switched off. If they are not swaps, they are bets, and the states keep their authority. The entire structure hangs on that one classification.

The word "swap" is the control point. Whoever wins the definition wins the market. Not the volume, not the liquidity. The definition.

// The courts just split, in public, six weeks apart

For a while this was theoretical. It stopped being theoretical this spring.

On April 6, 2026, a divided Third Circuit ruled in KalshiEX v. Flaherty that these contracts are likely swaps, that the Commodity Exchange Act preempts state gambling law, and it blocked New Jersey from enforcing against Kalshi. Two judges to one. The federal definition wins. The states are switched off.

On July 29, 2026, a federal judge in Wisconsin ruled the other way. He refused to give the CFTC the injunction it wanted, questioned whether these sports contracts are swaps at all, and held that Wisconsin's gambling statutes are not preempted. Wisconsin may go on enforcing against Kalshi, Coinbase, Robinhood, Polymarket, and Crypto.com. The federal definition does not win. The states are back on.

Two federal courts, six weeks apart, looked at the same word and gave opposite answers. That is not a loose end. That is the governance mechanism operating in the open. The Supreme Court has not taken it up. There is a docketed extension of time on the New Jersey side, granted into September, and no certiorari petition filed yet. Until it resolves, the answer to "is this a market or a bet" depends on which courthouse you are standing in. The definition is genuinely unsettled, and an unsettled definition is a live governance fight, not a legal footnote.

// Now the part my side of the room does not want to hear

Prediction markets came wrapped in the usual promise. Permissionless. A neutral venue where the crowd routes around the gatekeepers and prices reality directly. You have heard this promise about a hundred things. It is the promise that made a lot of us show up.

Look at what Polymarket actually did. It did not route around the state. It bought the state's permission. It acquired a licensed federal exchange, QCEX, for 112 million dollars, and it became a CFTC-regulated venue so it could operate in the United States at all. The most crypto-native prediction market on earth concluded that the way to have a market was to go buy the license to be allowed one. That is not a criticism of Polymarket. It is a description of where the power sits. The permission was never optional. It was the product.

And the CFTC that grants the permission just made the permission more discretionary, not less. In February it withdrew a 2024 proposal that would have banned whole categories of event contract outright. Then in June it proposed a new framework: no categorical bans, a contract-by-contract review where the Commission "may determine" whether each one is contrary to the public interest. The comment window closed on July 27. Read that as a shift and you will read it wrong. A categorical ban is a rule. A "may determine, case by case" standard is a discretion. The 2024 version told you in advance what was not allowed. The 2026 version tells you that the regulator will decide, one contract at a time, and you will find out what counts as a market when they tell you. The definitional power did not loosen. It concentrated, into a judgment call.

This is the same shape as every other control fight we have mapped this year, and it is worth saying plainly once. A permissioned pool, a jurisdiction-aware sequencer, a freeze function, a chartered issuer, a contract the CFTC may or may not let you list. In each one the technology got more open and the point of control moved to whoever writes the condition under which the open thing is allowed to operate. The market is not the venue. The market is the permission to run the venue, and the permission is a governance object held by whoever won the last ruling.

// Who actually holds the pen

Notice what is not in that table. You. The person pricing the outcome, supplying the information the whole thing claims to aggregate, is not a party to the decision about whether the venue is allowed to exist. That is not an oversight. It is the structure. The market was described to you as the place your judgment gets to matter, and the one judgment that determines whether the market exists is made entirely somewhere else.

// What you do with this

You do not get to decide whether a prediction market is a market. But you can decide whether you are willing to treat "permitted to exist" as the same thing as "free," because a lot of people are about to conflate them, loudly, in whichever direction the next ruling goes. When the Third Circuit side wins a news cycle, you will hear that the free market prevailed. When the Wisconsin side wins one, you will hear that consumers were protected. Both framings hide the same fact: the crowd never held the pen. The only thing being decided is which institution does.

The definition is still open. It closes the day the Supreme Court, or a new CFTC rule, picks one word and makes it stick. Watch that, not the valuations. The valuation tells you who is winning the market. The definition tells you who is allowed to hold one, and that decision is being made this quarter, in a comment file that closed on a Monday in July and a courtroom in Green Bay, by people who will never ask you what you think a market is.
