Could prediction markets hurt game integrity in poker?
Is it a risky proposition to host prediction markets for poker games where the players involved can bet against themselves?
One of my big predictions for the next 18 months is that poker, somehow, is going to embrace the world of prediction markets.
It might be just as a way to enhance the viewing experience (you heard it here first, the WSOP are surely going to partner with Kalshi or Polymarket this year, maybe as a broadcast partner of sorts). My bigger hunch is that we will see Kalshi or Polymarket actually offer online poker in some form.
Right now, there is a potential red flag, brought up by Blaise Bourgeois when discussing the Hustler stream markets on PolyMarket:
Prediction markets and cash game streams should probably stay separate.
If I'm one of these players, what's stopping me from betting $500K on myself to lose + then having "an off night" on stream?
The reality, at the moment, is nothing. It's not like poker has a governing body. pic.twitter.com/NfqXpr6o84

It could indeed happen, especially in a cash game, that somebody might have a conflict of interest if they bet on themselves on a prediction market, while also playing in a poker game on which the market is based. We have seen versions of this in other areas, where people have simply uttered words on broadcasts that are part of a "what will they say" prediction market.
To give you an idea of how insane and raw the markets still are, there was actually a live market for the winner of the NBC Heads-Up Championship, even though the event was finished, but the broadcast had not aired yet. There is little to no concern that people involved in markets may manipulate them.
Prediction markets are small in poker
Right now, there is not much concern for poker integrity because of liquidity. Poker prediction markets are small loss leader markets, designed to be a bit of fun for a small audience. The money on offer would not cause somebody to throw a game of poker.
Right now, there is a market for how many runners the WSOP Main Event will get, and only $11,000 has been traded on it. Most of the Hustler markets on Polymarket get similar trading volume.
This has always been the case. In Europe, there have always been betting markets on poker events like the WSOP. The odds tend to be terrible, the markets trade low volume and often the maximum bet size is restricted.
I can't foresee an issue for poker, unless prediction markets become so ubiquitous that so many more markets open up within poker, including for smaller events where it doesn't take much liquidity to make breaching game integrity a profitable option.
