Richie Miranda implied win probability:

Line Differences Worth Noting
All three books agree on Sousa as the favorite, but the spread across numbers is wide enough to reward line shopping.
On the Sousa side, Caesars is the steepest at -263, meaning you pay the most juice to back him there. BetOnline.ag offers the best number for Sousa backers at -250.
On the Miranda side, Kalshi stands out at +223. That is a noticeable bump above +207 at BetOnline.ag and +210 at Caesars. The 16-point gap between Kalshi and BetOnline.ag meaningfully affects both payout and implied probability, making book selection matter here.
Line shopping in MMA is genuinely valuable. A 10 to 15 point difference on a moneyline adds up over time, and the gap here is wide enough to move the needle. The Line Whale homepage lets you compare live odds across books side by side.
The Totals Market
BetOnline.ag is the only book currently posting a total for this fight, with the line set at 1.5 rounds. The Over is priced at -200 and the Under at +174.
That structure leans toward this fight ending before the midpoint of Round 2. The -200 on the Over is steep juice to pay just to get past 1.5 rounds, while the +174 on the Under offers real value if you believe either fighter has the finishing power to end things early.
What to Watch Before Fight Night
Line Movement
With six days until the fight, meaningful line movement is still possible. Any shift away from the current consensus is worth tracking. The Steam Moves tool on Line Whale monitors sharp line shifts and can surface early signals before the public catches on.
Fighter News and Weigh-In Results
Late scratches, injury reports, and weigh-in results can move MMA lines fast. A fighter missing weight or coming in heavy can shift the market sharply in either direction. Monitor official fight week updates and be ready to act if news breaks before Sunday.
Public Betting Percentages
If Miranda draws a large share of tickets, books may shade his line down from current levels to balance exposure. Getting in early on an underdog number can matter in a sport where lines move quickly once public money arrives.
Historical Finish Rates
Given the 1.5-round total, each fighter's tendency to finish or be finished early is relevant context for the totals market. Fighters with high early-stoppage rates on either side of that ledger support the current pricing structure.
