If you’re the biggest name in the world, and you want to bet your hard-earned money on, say, who dies on the White Lotus, then the absurdity of going up to an actual human bookmaker and saying those words is over. A prediction market will be more than happy to take your bets, and the whole world can get in on the action. Of course, the rules of prediction market platforms say that many people know the outcome you are betting money on. you should not place your betsBut, come on…
But even if we determine that TV bets are harmless, they come with a nasty externality: spoiler leaks.
For example, if you are planning to watch the finale of Top Chef: Carolinas On June 8, I cannot recommend clicking on this link to the Reality TV section of Polymarket. The community has reported a 97% probability for a certain contestant winning, and this level of consensus strongly suggests that anyone know anything.
According to Variety, a 97% probability was assigned to the winner by Kalshi users. Survivor 50: In the hands of the fans To be Aubrey Bracco, which he was.
Survivor host Jeff Probst criticized probability markets for Variety yesterday, saying, “They’ve found a way to cash in on Survivor”, adding, “It’s not a good fit for me as a human being. I get it – they’ve built a great business. They don’t care.”
Variety reports that Kalshi sent a push notification on the day of the final about Bracco’s apparently high probability of winning. “Aubrey at 97% – is the island already fixed?”. Notification was issued.
As if an unwanted push notification wasn’t bad enough for fans who were planning to tune in, spoilers like this have actually escaped control entirely, providing valuable allies for gossip-based social media accounts like PopCrave, which posted on X last year about Savannah Louie’s 86% chance of winning Survivor 49. that does it.

According to Variety’s reporting, Kalshi’s bet on Survivor falls into a very suspicious pattern. For example, one user gambled $45,500 on Bracco to make a relatively pitiful $4,500 profit. Total trading volume for survivor 50 The result was reportedly $32.7 million.
Variety points to Reality TV Reddit and a blog called RealitySteve as previous sources of reality TV spoilers for those who look for them before the finale. But that magazine notes that things are changing around spoilers. The Survivor 50 contestants – for many years considered the source of all reality TV spoilers – were this time denied advanced knowledge about the winner, and betting markets spoiled the show anyway, “A source says CBS was forced to consider the fact that any leaks would have to come from production,” as Variety said.
Probst placed the blame squarely on prediction markets in a self-contradictory statement to Variety, saying prediction markets “are the problem, not us. We went and created our show in a vacuum, and we keep it very tightly controlled, but if you’re so stupid and naive that you don’t think someone could leak it, that’s your problem.”
Meanwhile, a representative for Kalshi essentially said that the betting market included is a value-add for fans of the show, but added that the company is, “considering adding product features to prevent spoilers.”
