What US Open events you can trade on August 31st

The following day, Monday, August 31st, will be a continuation of the first-round events that kicked off the day prior. Day sessions will kick off at 11:00 AM ET on most courts and 12:00 PM ET at the Arthur Ashe Stadium. Night sessions at Arthur Ashe usually begin at 7:00 PM.

There are 128 players each for the men’s and women’s draws, which means 64 matches per singles draw. At Polymarket, markets are usually available on the matchups that viewers care the most about.

Where will the first-round matches be held?
