^ What's the line on Topuria? If it's anything crazy like 3.50 then you're like forced to bet on him because it's starting to go into price that's going to be +EV. Even if you lose, if the opportunity comes up again, the right move is to make the bet. :/
Do you mean odds? I just checked odds on flashscore and the history of odds look like this:
Previous odds: Volkanovski - 1.53 || Topuria - 2.63
Current odds: Volkanovski - 1.91 || Topuria 1.91
It seems, bookmakers keen towards Topuria. I look at the comments and Topuria had higher odds, I think 1.91 will be the final odd or if they increase Volk's odds and decrease Topuria's odds, that will be a huge mental shock for Volk. It probably already is when it moves from 1.53 to 1.91 and you are getting anticipated. Many people even compare this fight to Aldo - McGregor.
I don't think it's the book makers who are moving this line. From the odds history you have there, the books opened it at 1.53... Meaning they favor Volk. What moved the line could be sharp money thinking that Topuria at 2.63 could be value or maybe Volk isn't fully healthy rn. But yeah, it's weird. Best way to know is to check Volk's Insta and see what he's up to. :/
