(CNN)Jeb Bush projected a greater sense of confidence at the Fox Business Network Republican debate, but the former Florida governor's performance was not enough to bolster his support, according to CNN's Political Prediction Market, a game that invites users to test their political foresight.
Political Prediction Market: Bush slumps, Rubio leads
Before the Republican debate, Bush's odds to capture the Republican nomination were at 9% but fell to 7% by the end of the night. And, the odds of him suspending his campaign by January 1 are up by 13 points from 38% before the debate to 51%.
Bush, who jumped into the race at the top of the pack, had previously held the top spot with 25% odds of securing the nomination following CNN's Republican debate in September.
CNN's Political Prediction Market, however, is not a poll asking who a likely voter supports. It is a live online prediction game administered by a company called Pivit. It considers polls and other factors, including input from online players about who they think will actually win.
Rubio has seen a steady increase since his surge to 33% odds of winning the nomination following the CNBC debate last month.
Rubio's odds of winning the nomination jumped 32 points since the CNN Republican debate on September 16, even though his support in polls has not shown nearly that level of increase.
He is currently leading the GOP pack with his odds of capturing the Republican nomination rising from 40% before the debate to 45% by the end of the night. He is followed by billionaire businessman Donald Trump, whose odds of winning the nomination are up 2 points from 18% pre-debate, to 20%.
They are followed by Texas Sen. Ted Cruz at 11% odds of winning the nomination and retired neurosurgeon Ben Carson at 6%.
Meanwhile, New Jersey Gov Chris Christie's demotion from the main stage to the undercard debate seems to have worked in his favor, according to CNN's Political Prediction Market.
While Christie's odds of securing the GOP nomination are a mere 1%, the odds of him suspending his campaign by January 1, 2016, are down from 78% before the debate to 57% by 11 p.m. Tuesday night.
Meanwhile, Ohio Gov. John Kasich's odds of dropping out the race by January are up 8% to 95% and former Arkansas Gov. Mike Huckabee's odds of suspending his campaign are up 4 points to 89%.
