Odds for Donald Trump winning the presidential election have changed significantly after his first debates. Where he stands since last week's debate.

Vice President Kamala Harris expanded her lead over former President Donald Trump as the bookmakers' favorite to win the November election on Wednesday night, as post-debate polls showed a bump in Harris' favor in key swing states.

Overall, Harris has a 51.6% chance of becoming the next president. Trump, who enjoyed a nice lead over President Joe Biden when he was the Democratic nominee and Harris when she first replaced Biden, now has a 46.7% chance of winning.

The presidential debate between Vice President Kamala Harris and Ex-President Donald Trump shifted the betting odds for the winner on Election Day. Here’s a look at who has the edge and how the markets have shifted in recent months.

BetOnline saw their odds, previously favoring Trump, flip to Harris after the debate. As of 11 p.m. on Tuesday, BetOnline gave Harris a slight lead of -120, with Trump just behind her at +110. This marks a reversal since 9 a.m. on Tuesday when the bookmaker had Trump a slight lead of -120, while Harris had odds of +100.

Harris beating Trump 50% to 46%. It comes after Harris enjoyed a week of positive news coverage following the Sept. 10 debate, which even some Republicans deemed " disastrous " for the Trump campaign.
