Donchenko vs. Soriano: Breaking Down the Implied Probabilities
At the current line, here is what each side implies in terms of win probability:
Daniil Donchenko -233 Divide 233 by (233 + 100). That gives Donchenko an implied win probability of approximately 70.0%.
Punahele Soriano +192 Divide 100 by (192 + 100). That works out to an implied win probability of roughly 34.2%.
The combined implied probability adds up to approximately 104.2%, reflecting the sportsbook's built-in margin, also called the vig or juice. That overround is standard across the industry and worth factoring in when assessing true value on either side.
The Current Market
BetOnline.ag is the only book posting a number on this fight right now. That is not unusual for a non-main event UFC bout this far out. As September 5 approaches, expect more sportsbooks to post lines and the market to sharpen. Shopping across books becomes especially relevant when the underdog price sits near +200, where even a 10 to 15 cent difference shifts your payout noticeably.

What to Watch For: Key Factors That Could Move the Line
Fighter Profiles and Style Matchup
Donchenko's -233 opening price reflects the books' early read, but MMA markets at this stage are often based on limited data. As fight camps wrap up and more information surfaces, sharp money can move lines significantly. Any meaningful shift in that number is a signal worth noting.
Soriano's Underdog Value
At +192, a winning bet on Soriano returns nearly double the stake. Underdog value in MMA is real because the sport's finishing nature means any fighter can end a bout with one clean strike or submission. The market is not saying Soriano cannot win. It is saying he is expected to win roughly one in three times at this price, which gives bettors who believe he is undervalued a reasonable position to argue.
Line Movement as a Signal
How a line moves from open to close is one of the more useful indicators in MMA betting. If Donchenko drifts from -233 to -280 by fight week, it suggests sharp and public money aligning behind him. Movement in the opposite direction, toward -200 or less, could signal professional money on the underdog. Tracking Steam Moves is one way to stay ahead of significant shifts before the general betting public adjusts.
Injuries, Late Scratches, and Camp Reports
Missed weights, undisclosed injuries, and late replacements can all flip an MMA line. Staying current through fight week is essential, particularly for a matchup still 13 days out where conditions can change quickly.
Event Context
Where a bout sits on the card matters. Main events and featured fights generate more market liquidity and generally sharper lines. Undercard bouts can carry softer numbers, which creates more opportunity for bettors who do their homework.
Bottom Line
Donchenko is a clear favorite at -233 with an implied win probability near 70%. Soriano sits at +192 as a live underdog with a roughly 34% implied chance. With only one book in the market this far out, these lines have room to move. Monitoring movement and shopping across books as fight week arrives will be key to finding the best available price on either side.
