Polymarket users already know who is going to win the National Heads-Up Poker Championship, yet many of them are betting against him. The market on the show’s outcome has been a farce since the week it opened, as someone assumed to have insider knowledge pushed the price on one particular player up to 99 cents (a 99% chance) within the first few days. In recent weeks, it has somehow managed to become even more absurd, as the price for the known winner has dropped to around 60 cents.
To make this article readable by those who haven’t already been spoiled, we won’t discuss the player by name. However, if you want spoilers you can read our coverage of the original incident.
So, why are Polymarket users betting against someone they all know has already won? Because there’s suddenly uncertainty over the terms of the market contract. The show was originally expected to air in “Fall 2025,” but hasn’t started yet. That means the contracts are looking like they’ll run up against their deadline.
The rules for “2025 National Heads-Up Poker Championship Winner” state:
If the 2025 National Heads-Up Poker Championship is canceled or not completed by December 31, 2025, 11:59 pm ET, this market will resolve to “Other”.
If that were to happen, No shares on each particular player would pay out. For these sorts of multiway markets, Polymarket also allows users to convert No shares on one proposition into Yes shares on the alternatives. Since every other player beside the presumed winner is trading below 1 cent, that effectively means converting to Yes shares on Other.
What Does it Mean to ‘Complete’ a Pre-Recorded Event?
Based on user comments on the market, there seems to be strong consensus on two points:
- There has definitely already been a winner, and it’s an open secret who that is.
- The final episode of the show won’t air until after January 1, 2026.
And yet, there are still people taking both sides of the market. What that means, effectively, is that users are betting on how the dispute resolution will go.
One of Polymarket’s fundamental differences from a regulated peer like Kalshi is that it doesn’t make that determination in-house. Rather, its “oracle” system is tied to a cryptocurrency token, UMA, whose owners effectively get to vote on what constitutes truth. It’s not uncommon that those votes end up deciding who gets paid and who is left holding the bag.
In other words, the market on “2025 National Heads-Up Poker Championship Winner” no longer has anything to do with the winner. Instead, it has become a bet on how UMA whales understand the word “complete.”
Is the tournament complete because the matches have been played, albeit in secret? Or is it complete when the outcome officially becomes part of the public record, because the final episode has aired?
This interaction between two users sums up the situation and the attitude many users have taken to it(edited for clarity and to avoid spoilers):
Nanjh: I don’t understand this. [Player] won already, but if you bet on him and it doesn’t air by the end of 2025, you lose all the money you wagered? Why is this on Polymarket?
CrewKings: Man, no one knows anything. Make your assumptions and bet. This is why Poly is fun.
A Clash of Cultures Brewing
Although the rules uncertainty might be “fun” in the eyes of some users, it highlights one of the challenges Polymarket is going to face as it enters the regulated U.S. market through a subsidiary.
Its current international userbase is, essentially, the crypto community. They’re used to making bets on what other people are going to think and do, often in ways that are almost completely untethered from the real world.
But for prediction markets to be legal in the U.S. requires clinging to the notion that event contracts are financial products. They must be seen as suitable for regulation by the same body concerned with futures on the price of oil and gold.
One could argue that conventional speculation is also nothing but a bet on what other people are going to think and do. Nonetheless, Wall Street strives for market stability. Achieving that requires public faith in the idea that prices have some real-world basis. Extreme volatility and market bubbles are considered a bug, not a feature.
Current Polymarket users may be content to view it as a big joke, where the goal is to make sure you’re not the punchline. However, Wall Street sees itself as serious business.
There is a clash of cultures brewing here, on top of all the legal jurisdictional issues that prediction markets have already created.
The owner of the New York Stock Exchange has a $2 billion position in Polymarket. There’s no turning back now. Old-school financiers and memecoin “HODLers” are in bed together, and they’re all about to find out what that means.
