We take a look at how the odds have changed in the lead up to the most anticipated fight in years.
The "superfight" between Floyd Mayweather Jr and Conor McGregor was formally announced on 14th June.
At that point, it was generally accepted that the fight would be a complete mismatch between the unbeaten Mayweather and the unproven McGregor, in the boxing ring. Mayweather could be backed at 1/12 and McGregor at a very long 7/1.
There was an initial market reaction to those prices, which, in the first week saw the Irishman's odds fall to 5/1, with Mayweather at 1/7. Over the next month until the middle/end of July, McGregor's odds continued to fall to the point where he could be backed at 4/1 and Mayweather 1/5.
As the press tour came to an end, there was a definite feeling that McGregor could hit hard enough to cause Mayweather problems and as we've got closer to the fight his odds have continued to fall.
Over the last two weeks and leading up to the fight this week, McGregor has even dropped below 3/1 at times with some bookies quoting 13/5 and 11/4. With only one day left until the two fighters get into the ring, support has started to come for the undefeated champion though.
As of Friday afternoon, Mayweather has shortened to a best price 2/9 and McGregor back out to above 3/1. He can even be backed at 4/1 in places.
We would expect that trend to continue in the hours leading up to the fight with bettors taking advantage of the current Mayweather price. One thing that the betting has proved though is that McGregor is not to be underestimated.
