The US presidential election betting market began to have a drastic change in the direction of betting more on the possibility of Mr. Trump winning.

The US presidential election betting market has begun to change strongly in the direction of betting more on the possibility of Republican candidate Donald Trump winning a second term, Reuters news agency said.

The UK betting platform Smartket is betting 55% on Trump’s chance of winning, compared with just 39% at the time of the opening. Sometimes, the bet on Mr. Trump is up to 80%.

By contrast, the bet on Mr. Biden on Smartket dropped to 45% from the original 61%.

This correlation change “was mainly due to Trump’s victory in Florida, an important battlefield state,” said Patrick Flynn, analyst at Smartkets. According to the analyst, the end result is likely to depend heavily on unregistered votes in key states like Pennsylvania, Michigan and Arizona.

Betfair bookmakers in the UK are betting on a 75% chance of Trump winning Biden, from 39% in the morning of November 3. In particular, the bet on Mr. Biden reduced to 25% from 61%.

“Mr. Trump has made a major step forward in terms of votes, it shows tonight could be a troubling night for Mr. Biden,” Betfair spokesman Sam Rosbottom said.

PredictIt forecasting site in New Zealand said that Trump’s chance of winning is 63%, compared with 37% of Mr. Biden, from a 61% -44% correlation in favor of Mr. Biden on 2/11.

According to Ms. Deeley, elections officials are waiting for the live ballot data reported by each district to be entered into the system, and then reporting the number of ballots by mail. Reporting delays in the number of direct votes in some areas, especially in the west of the city, has slowed overall results, Deeley said.
