This chart shows how drastically Donald Trump's odds of winning the election are improving

More and more people are putting their money on Donald Trump to win the 2016 presidential race.

Paddy Power, Ireland’s largest bookmaker, is taking bets on the election and they provided Business Insider with data on Trump’s odds since late 2013.

Since announcing his campaign on June 16, Trump has vaulted to the top of many polls of the Republican field and his odds have dramatically improved. This chart shows just how rapid his rise has been.

Though bettors are clearly becoming more confident in Trump’s chances, Paddy Power still gives Florida Gov. Jeb Bush (R) the best odds of winning the Republican nomination. The bookmakers also have Sen. Marco Rubio (R-Florida) and Wisconsin Gov. Scott Walker (R) ahead of Trump in the GOP contest.

Trump isn’t the only one who’s seen his odds improve of late. Vice President Joe Biden has seen his chances more than double amid reports he’s seriously considering entering the race. On June 18, Paddy Power gave him 20/1 odds, but on Sunday he was at 9/1.

Overall, Democrat Hillary Clinton remains Paddy Power’s favourite to win the election with odds of 10/11. Bush is in second place at 10/3.
