Gamblers are predicting that Republican Glenn Youngkin will win Virginia’s tight gubernatorial race Tuesday.

According to Oddschecker, which displays odds that come directly from overseas bookmakers, Youngkin’s odds have shortened to 4-6 — meaning a $6 wager would result in a $4 win, should the Republican prevail. Democrat Terry McAuliffe is now an 11/10 underdog — meaning someone who bets $10 would win $11, if the Democrat comes out on today. McAullife was a heavy 1-4 favorite in the same markets as recently as a month ago.

The odds come during a tight race, with recent polls showing Youngkin in the lead by merely one point. A PollSmart MR poll released on Monday — a day prior to election day — even showed McAuliffe leading Youngkin by four percentage points among likely voters.
