UFC 271 Market Report: Bettors Favoring Robert Whittaker to Upset Israel Adesanya in Main Event

Bettors getting in on the UFC 271 pay-per-view are backing the underdogs, including Robert Whittaker to top Israel Adesanya in the main event for the middleweight title.

Adesanya (-275) defeated Whittaker (+230) by knockout to win the belt back in 2019. He's successfully defended his belt three times since, with wins over Yoel Romero, Paulo Costa and Marvin Vettori. He came up short in his quest for the light heavyweight title, suffering his lone professional defeat in March to Jan Blachowicz.

Whittaker has won three in a row since that loss to Adesanya, beating Darren Till, Jared Cannonier and Kelvin Gastelum all by decision.
