The chances have increased, according to British bookies, that President Donald Trump will leave the White House before his four-year term is over.

The bookmakers have seen a stream of bets that Trump will depart early after a report Tuesday that he asked the since-fired FBI director James Comey to shut down a probe into links between his inner circle and Russia.

“Overnight we’ve seen more than [£5,000] bet on Trump to leave before the end of his first term, and we expect to see a lot more bet today, with his odds now shortening from evens into 5/6,” Katie Baylis, spokeswoman at Betfair UK:PPB , said in a note Wednesday morning. That implies a 55% probability that the president will exit before his term ends.

“And many punters think it won’t be too long before he departs, with the odds of him leaving this year now into 12/5 from 11/2 — a 27% chance [up] from 16% before the latest allegations,” Baylis added.

Later on Wednesday, Betfair said punters had bet another £13,000 that Trump will leave before the end of his first term.

Tuesday’s Comey reports came a day after other reports that Trump had shared classified intelligence with top Russian officials at a meeting last week. Also last week, Trump fired Comey in a move he told NBC’s Lester Holt in a TV interview was at least in part tied to the former FBI director’s investigation into Russian connections in the president’s circle.

Taking all those developments together, bettors are now seeing a greater chance that the commander-in-chief will be impeached. At Irish bookie Paddy Power, the odds of an impeachment stand at 2/1, or a 33% chance, while an outright Trump resignation is priced at 15/8, implying a 35% chance.

“Impeachment has been a hugely popular topic ever since Election Day — when it was 16/1, immediately after news of Trump’s victory emerged. By the time of his inauguration, the price was at 10/1,” said Lee Price, spokesperson at Paddy Power, in emailed comments.

“We’ve been betting on impeachment for all recent U.S. presidents but, even at the height of the Lewinsky scandal, Bill Clinton was only ever 6/1 [14%] to be impeached,” he added.

Should an impeachment effort clear the House by majority vote, it would then require the backing of two-thirds of the Republican-controlled Senate.
