With deadline day just around the corner, the rumor mill is heating up so are MLB trade deadline prediction markets. That’s why if you haven’t done so, then now might be a good time to make your picks.
However, if you don’t know how or where to make your picks, then you’re in luck because there are several prediction market sites that are rolling out special promos just in time for the MLB trade deadline.

The best MLB trade deadline prediction market sites
Looking at how the past few weeks have unfolded, it honestly feels like every team is either making calls behind the scenes or being linked to the next big trade. Left-handed pitcher Connelly Early was moved from the Red Sox to the Nationals last week while the Rangers shored up their lineup after trading Angel Arredondo to the Angels for Chase Silseth and Logan O’Hoppe. With the next few days expected to go much crazier than that, here are some of the top prediction market platforms that let you join in on the action.
