A prediction market is a site where people bet on future events. Polymarket, along with the larger company Kalshi, offers bets on many topics, from politics to movies and games.
Polymarket has offered some unusual markets. One asked if the US would confirm that aliens exist. Another focused on a possible nuclear war. That market now seems to have been removed after many people online said it was wrong to bet on an event that could kill millions of people.
These sites have grabbed attention because they let people bet on current events, even when it may seem wrong. They have also grown because they make betting feel simple. Users often see a yes or no choice and a percentage instead of betting odds such as 5-1 or 11-2. Some bets are less serious, such as guessing the release date of Grand Theft Auto VI or the Oscar winner.
However, the sites also face questions about cheating. Reports say some users with inside knowledge made money by betting on major events. These included the US plan to capture the Venezuelan president and the attack on Iran.
Until recently, US officials and the companies seemed less worried about this problem. Last month, Kalshi said it stopped two users from betting and fined them for cheating. It also said it was looking into 200 possible cases of breaking the rules. As anger over war betting grows, authorities are looking more closely at these companies.
