I saw that Kalshi controls 89% of the prediction market in the US. So almost the entire market is managed by this one platform. Imagine, could a highly regulated area like the American stock market be this concentrated? It's an interesting situation, especially as it shows how quickly prediction platforms can establish market dominance. Strict regulation creates trust on one hand, but on the other hand, it seems to limit competition. I wonder how difficult it is for other players to enter.
