MLB Partnered with Polymarket as the league’s official prediction exchange.

I like prediction markets better than betting markets since you can get out at any time. If you buy the Rockies to win the NL West at 0.01 on opening day, you cash out when they are leading the division by five games on June 1 and selling at 0.40.

In that regard, I hope that these markets avoid extremely short term plays. Game level is probably best (hits in a game, runs in a game, etc.). Let the casinos handle the short action.
