What the Odds Say
Andre Petroski and Azamat Bekoev meet on Saturday, October 31 at 5:00 PM PDT, and the betting market is sending a clear message: Bekoev is a substantial favorite across every book carrying this fight.
Bekoev's moneyline ranges from -345 at 1xBet to -435 at NordicBet. That spread is worth paying attention to before placing any money. Petroski's underdog price runs from +276 at 1xBet up to +300 at BetOnline.ag. The books agree on the direction but not the size of the gap, and that disagreement creates real opportunities for bettors shopping lines.

Line Shopping Matters Here
The spread between books is wide enough to make line shopping a genuine priority on either side.
For Bekoev backers, the best available price is -345 at 1xBet. At -435 on NordicBet, you risk $90 more for the same $100 return. Both bets require Bekoev to win, but that difference compounds over multiple wagers.
For Petroski, BetOnline.ag offers the best number at +300. That's 24 cents better than 1xBet's +276 on an otherwise identical bet. On a $100 wager, that's the difference between collecting $300 and $276.
The draw price at 1xBet (+6900) is listed for reference. MMA draws are rare enough that this line is largely academic.
What to Watch Heading Into Fight Week
Line Movement and Sharp Action
With eight days until the fight, lines can shift meaningfully as sharper money enters and public wagering builds. The current spread between books suggests pricing hasn't fully converged yet. If Bekoev's number tightens across the board, that typically signals sharp consensus. Movement toward a shorter favorite price, or a lengthening underdog number for Petroski, is worth noting as a potential signal.
The Line History tool tracks movement across more than 100 sportsbooks over 30 days, useful for following how this number evolves before fight day.
Fighter-Specific Factors
Key variables to monitor include fight camp updates, card positioning changes, and official weigh-in results. MMA lines are particularly sensitive to weight cut news and late scratches, so staying current through fight week matters regardless of which side you're on.
Bekoev's heavy favorite status implies the books see a meaningful skill or style edge. The question for bettors evaluating Petroski at plus-money is whether a viable upset path exists, and at what price that path represents value.
Arbitrage Potential
The gap between 1xBet's Petroski price (+276) and tighter Bekoev prices elsewhere is narrow but worth checking. If you hold accounts at multiple books, the Arbitrage Calculator can tell you whether a two-sided position locks in a guaranteed return at current lines.
The Bottom Line
The market is aligned on Bekoev as a strong favorite, with implied probabilities clustered around 80% across all listed books. Petroski's best available price of +300 at BetOnline.ag reflects his underdog status but also represents the kind of number where a bettor who sees a realistic upset path might find value. Neither side should be approached without checking multiple books first, given the meaningful spread between the best and worst available prices.
