Sports as a % of total trading volume on Kalshi has been consistently falling since the start of the 2025 NFL season. Sports is now roughly 58% of the total volume. A large part of this is the rise of crypto-related markets. Over time, as new categories emerge, I would argue this drops to teens and then maybe even single digits.
EXCLUSIVE: Jeff Probst slams prediction market platforms like Kalshi and Polymarket for allowing users to make trades about who won “Survivor” 50, saying that the companies are “incentivizing people to lie, cheat and steal to get ahead.” “They have figured out a way to capitalize on [the show],” he tells Variety. “It doesn’t sit well with me as a human. I get it — they built a great business. They don’t care. I’m not happy about it.” “Clearly, if 90% of the people are voting for somebody, there’s a leak. But to look at us, the producers, as though we have a problem, is the mirror pointing in the wrong direction,” he says. “[Prediction market platforms] are the ones with the problem, not us. We went and made our show in a vacuum, and we keep it very tightly contained, but if you are foolish and naive enough to not think that somebody might leak it, that’s your problem.” variety.com/2026/tv/news/s…
Prediction market vs. state-regulated sportsbook. What happens if you bet $10 on the favorite in first-round games, and win them all? Don't invest in the prediction market hype. When you place you bets against Wall Street, you're not going to come out ahead.

wtf…people who bet 49ers win total correctly were only reimbursed cost and not winnings when it was graded wrong? And they won’t just eat it?
