After the debate between Republican vice presidential candidates JD Vance and Democrat Tim Walz, Mr Trump's odds of winning the November election have increased.
According to some leading bookmakers, former US President Donald Trump's odds of winning the November election have increased after the October 1 debate between the two vice presidential candidates of the Republican Party, Ohio Senator JD Vance and the Democratic Party, Minnesota Governor Tim Walz.
Before the Vance-Walz debate, bookmaker Betfair, which had thought US Vice President Kamala Harris was the clear favorite to win, reversed that on the morning of October 2 and placed Mr. Trump slightly ahead of Ms. Harris.
Several other bookmakers such as Paddy Power and Spreadex have also made similar decisions.
On October 1, Mr. Vance and Mr. Walz faced each other in a relatively moderate, policy-focused debate, in which the two sides clashed on a number of issues such as immigration and gun control.
Six Newsweek journalists concluded that Mr. Vance won the debate, while two said Mr. Walz prevailed and four said the two sides were tied.
On October 1, bookmaker Betfair gave odds of 20/21 (equivalent to 51.2%) for Ms. Harris to win the US presidential election this year. By the morning of October 2, this odds were 21/20 (equivalent to 48.8%), while Trump's odds of winning were 1/1 (equivalent to 50%).
"This is a very volatile betting market, the odds have completely flipped and Donald Trump is the top candidate on the Betfair Exchange again," Betfair spokesman Sam Rosbottom told Newsweek.
"Kamala Harris had a 20/21 chance of winning the November election yesterday (October 1), but that chance has changed to 21/20 after last night's vice presidential debate," added Sam Rosbottom.
According to Mr. Sam Rosbottom, with the US presidential election just over a month away, this new development makes the race to the White House hotter than ever.
Newsweek reached out via email to representatives of the Trump and Harris campaigns for comment on the morning of October 2.
On October 1, before the debate between the two US vice presidential candidates, bookmaker Paddy Power offered odds of 1/1 (equivalent to 50%) for Trump to win, but by 2am on October 2, the odds were 9/10 (equivalent to 52.6%).
Similarly, on October 1, bookmaker Spreadex offered odds of 19/20 (equivalent to 51.3%) for Mr. Trump to win, but on the morning of October 2, the odds changed to 10/11 (equivalent to 52.4%) immediately after the debate between Mr. Walz and Mr. Vance.
Mr. Trump's winning percentage was also adjusted by Star Sports after the debate between the two US vice presidential candidates, from 21/20 (equivalent to 48.8%) to 19/20 (equivalent to 51.3%).
"The American people are just over a month away from voting, but the gap between Kamala Harris and Donald Trump is extremely tight," Star Sports political betting analyst William Kedjanyi told Newsweek.
According to expert William Kedjanyi, with Mr. Vance considered to be dominant according to polls from CNN and CBS, Mr. Trump has returned to the top candidate position with a ratio of 19/20 (equivalent to 51.3%) instead of 21/20 (equivalent to 48.8%) and now there is no gap between the two US presidential candidates.
According to a CNN snap poll of registered voters who watched the vice presidential debate, 51% said Vance won, while 49% backed Walz. The poll has a margin of error of +/- 5.3 percentage points.
