We’re about halfway through the year, and through the end of May the UFC has staged nearly 300 fights. That’s a lot of betting action for five months, and as usual, there’s been a good number of upsets. The UFC odds at BookMaker.eu has covered every single one, which means there have been plenty of opportunities for you to come out a winner.
The overall numbers show that through May, there have been 121 favorite wins and 70 underdog wins. One card, UFC 234, was the only event where every favorite emerged victorious. And so far, only UFC Fight Night: Assuncao vs. Moraes 2 has produced more underdog winners than favorites.
For context, in 2018 there 419 total fights, and 277 favorites won against 142 underdogs. That’s nearly 2-1 in favor of the chalk plays, but there were a lot of ‘dogs that pulled through.
We’ll compile the totals at the end of 2019 of course, but today we’re looking at the numbers from each of the cards to give you a closer look into how things have played out.

The biggest upset of the mid-year is Allen Crowder beating Greg Hardy at +375. We know hindsight is 20/20, but this was one that was more predictable than others. For starters, Hardy as making his UFC debut with just three pro fights on his resume. Prior to that, he notched sub-minute KOs against really questionable competition. Allen Crowder was a nine-fight veteran who turned pro in 2014. We had know clue how Hardy would perform past the first round, but with zero combat sports experience nobody should have assumed it would have been good.
We’ve also got a few notable main event upsets here. Hermansson beat Jacare Souza at +170, Poirier took the W against Holloway at +175, Masvidal handled Till at +190 and Pettis prevailed at +300 against Wonderboy. Each of those ‘dogs had a solid argument, but the Showtime winner was a shocker - he was getting soundly outstruck by Thompson before a flying superman punch ended the fight in a blink. Just another reminder that anything can happen in this sport.
