Trump odds dip as Kamala Harris sees huge surge... who are the other runners and riders from Gavin Newsom to Michelle Obama

Donald Trump's odds to win the Oval Office are now at -156 following Joe Biden's decision to drop out - meaning oddsmakers view him as being 61 percent likely to surface as the next president come November.

It stood as a slight dip from a day ago when the president's odds were pegged at 64 percent, suggesting some uncertainty as Democrats mull a new candidate. 

In contrast, Biden's odds plummeted to essentially zero, according to PredictIt - as his Vice President, Kamala Harris, saw her odds slashed to +163. That's down from the +900 seen just days ago on July 16, and way down from back in June, before Biden's disastrous debate performance, when her chances were +2400. 

This means oddsmakers have pegged her as being 12 times more likely at pulling off a win as she was a month ago, when handicappers saw Biden's odds as around 50-50.

That statistic has since halved more than six times over, as the election rapidly approaches. As it does, other figures have some surprising odds as well, from California's Gavin Newsom to former First Lady Michelle Obama.

Donald Trump: -156

The poll, which is widely seen as an effective and reliable measure of predicting elections, shows Trump comfortably leading despite a small slip-up seemingly triggered by Biden's decision to bow out.

He started the day with a line of -178, now down to -156.

While not the most reliable of information aggregators due to journalists and political staffers being disallowed from casting, the site and its odds marker is widely considered an effective and reliable measure of predicting elections

 Kamala Harris: +163

Harris, meanwhile, started last week as a long-shot with 10-1 odds, even as many pegged her as the apparent replacement as many called on Biden to drop out.

This prospect took a step closer to becoming a reality almost immediately Sunday, after her old running mate took to X to make the highly anticipated announcement.

Within seconds, her chances spiked by nine percent, after already improving by 17 percent over the course of last week.

This means oddsmakers have pegged her as being 12 times more likely at pulling off a win as she was a month ago, when handicappers saw Biden's odds as around 50-50. That statistic has since halved six times over. As the election looms, others had some surprising odds as well

 Joe Biden: +9900

The next-most dramatic shift was sported by Biden, whose stock slipped from +567 to nearly 100-1 again in seconds, after sloping down from 48 percent since his debate last month. 

Despite confirming in his statement he would be 'stand[ing] down,' PredictIt still pegged him as having a small, 1 percent chance of somehow still snagging the presidency.

The next-most dramatic shift was sported by Biden, whose stock slipped from +567 to nearly 100-1 again in seconds, after sloping down from 48 percent since his debate last month 

This comes ahead of the highly anticipated Democratic Convention, where, for the first time in decades, a candidate will likely be chosen by delegate votes just ahead of the event.

This concept, however, failed to garner any other candidates a surge in odds as well, as Biden put to bed any doubt following his announcement by offering Harris his own endorsement.

Hillary Clinton: +10000

Also offering her seal of approval was former Democratic candidate Hillary Clinton, who, while not ranked on PredictIt, sported a similar +10000  line on competing market Oddschecker.com of winning the presidency.

That means the site views her as being just shy of a 100-1 shot, similar to Biden. Both have now endorsed Harris as the next president.

Most of Harris's prospective competition, meanwhile, saw their odds stay relatively the same.

Gavin Newsom: +2400

Newsom boasted a line of +2400 - or 24 to 1 - unchanged from the day before.

Other Democrats, like United States Secretary of Transportation Pete Buttigieg, saw their chances stay at around a measly one percent.

Michelle Obama: +43000

Michelle, meanwhile, was not even ranked by PredictIt, but on Oddschecker, she was awarded a line of +4300.

This means oddsmakers there see her as being more than twice as likely to assume the presidency than Clinton, but still view her as a massive underdog.

That said, Oddschecker also granted Harris a line of +275, meaning oddsmakers running the site see the chance of a Harris win as less likely than those at PredictIt.

Michelle, meanwhile, was not even ranked by PredictIt, but on Oddchecker, she sported a line of +4300 - or 43 to 1. This means oddsmakers there see her as being more than twice as likely to assume the presidency than Clinton, but is still a massive underdog

Gretchen Whitmer: +6400

Michigan's Gretchen Whitmer was another potential replacement not ranked by Predictit, but Oddschecker pegged her as having less of a chance than Michelle, with a line of +6400.

The site pegged Trump as having a line of -156 - almost identical to the line produced by PredictIt.

Republicans like Vivek Ramaswamy and Glenn Younkin remain the longest shots of all candidates, as a Trump nod from the GOP is all but secured.

The same certainty cannot be said from the Democratic Party, which will have its work cut out for it as it seeks to put forth a sole candidate in time for the DNC.

The DNC will be held in less than a month, from Monday, August 19, through Thursday, August 22. 

On Sunday, Vice President Harris said she intends to 'earn and win' the Democratic presidential nomination by that point.
