Best MLB Prediction Markets for Sunday’s Games on August 9th

August 9, 2026
by Emma Harrison

It will be a busy Sunday at the MLB prediction markets as a full 15-game schedule sees teams looking to strengthen playoff ambitions, extend division leads, and show off the trade deadline’s biggest acquisitions.

The action gets underway at noon, ET. with Cincinnati visiting Washington and continues through to Houston’s prime time meeting with San Diego. Other highlights include the Dodgers, burnished with the arrival of Tarik Skubal, visiting Arizona, Atlanta going to the Yankees, and Toronto at Philadelphia. Almost every game has something riding on it.

The biggest MLB games this Sunday

Although Skubal is not in the rotation to pitch this Sunday, his arrival at the Dodgers makes their trip to Arizona even more interesting, as his arm is considered to be the key piece in a jigsaw that should end up looking like a realistic World Series shot. With LA aiming to become one of just three franchises in the Divisional Era to win a third consecutive World Series, the top prediction market platforms will be taking a close look at all their remaining games.

Additional areas of focus include Boston’s home showdown with the Oakland As. The Sox added Adley Rutschmann to an improving side with a real shot at the AL East. MLB prediction markets will also be zoning in on the Phillies, who host Toronto with Luis Arraez in their lineup. A three-time batting champion, Arraez will be hoping to add some scoring potential to the home lineup.
