Betting odds indicate 55 percent chance of "In" ahead of UK's EU vote - Betfair
The implied probability of a British vote to stay in the European Union fell to 55 percent on Tuesday, sliding steadily from 59 percent earlier in the day and down from about 64 percent on Monday, according to betting odds from Betfair.
The implied probability of an "In" vote on June 23 fell after three separate polling firms put the "Out" campaign in the lead.
As recently as last Thursday betting odds indicated a 78 percent probability of an In vote, according to Betfair, before the level started to fall as the "Out" campaign build momentum.
