Casey O’Neill vs Eduarda Moura Betting Prediction: UFC 331 Overview
Casey O’Neill and Eduarda Moura meet in a women’s flyweight bout at UFC 331 on Saturday, September 19, 2026.
The fight is scheduled for Crypto.com Arena in Los Angeles as part of the early preliminary portion of the card. UFC 331 is headlined by the flyweight title rematch between Joshua Van and Alexandre Pantoja.
O’Neill enters with a professional record of 11-2 and has rebuilt momentum after the first losing streak of her UFC career.
She suffered consecutive defeats against Jennifer Maia and Ariane Lipski before returning to the win column against Luana Santos. O’Neill then followed that decision victory with a first-round knockout of Fernandes in March.
Moura brings a different profile.
She is 3-2 across her UFC appearances and has already faced several experienced opponents. Her victories over Murphy and Hardy demonstrated that she can compete effectively in extended fights, but her losses to Denise Gomes and Wang Cong exposed some of the challenges she can face against opponents who maintain a high striking pace.
That makes this an intriguing flyweight matchup.

The current betting market makes O’Neill the clear favorite, but the matchup is more competitive than the moneyline alone suggests.
O’Neill’s recent form is encouraging, while Moura has enough experience to make this a difficult fight if she can slow the pace and force longer grappling exchanges.
Casey O’Neill’s Recent UFC Resurgence
O’Neill’s current run is important when evaluating this Casey O’Neill vs Eduarda Moura Betting Prediction.
She entered the UFC with significant momentum and won her first several fights inside the promotion. However, consecutive losses to Jennifer Maia and Ariane Lipski temporarily halted that rise.
Instead of allowing those losses to define her career, O’Neill responded with two victories.
First came a unanimous decision against Luana Santos.
Then came the most impressive result of her recent run.
O’Neill stopped Gabriella Fernandes by first-round TKO in March, giving her a finish after previously relying heavily on decision victories.
That finish is particularly relevant because O’Neill has historically produced a high volume of significant strikes.
One current statistical breakdown lists O’Neill at approximately 7.89 significant strikes landed per minute, placing her among the highest-volume strikers in the UFC.
That volume can become a major advantage over three rounds.
O’Neill’s Striking Volume Could Be the Difference
O’Neill’s striking numbers are one of the most important elements of this matchup.
She does not necessarily need to land one enormous shot to control a fight.
Instead, she can build an advantage through activity.
That approach creates several problems for Moura.
First, Moura must constantly defend.
Second, O’Neill can accumulate points even when individual strikes do not produce significant damage.
Third, the pressure can make it harder for Moura to establish her own offensive rhythm.
O’Neill’s recent first-round TKO also adds another layer to the matchup.
Opponents cannot simply assume that her high-volume approach lacks finishing potential.
At the same time, bettors should not automatically expect another knockout.
Her previous UFC career contained many decision victories, and Moura has demonstrated durability against experienced opposition.
That makes a decision victory an interesting secondary angle.
Eduarda Moura’s UFC Experience
Moura enters UFC 331 with a 3-2 record inside the promotion.
She has already faced experienced competition and has demonstrated that she can win fights through sustained pressure and decision-making.
Her victories over Lauren Murphy and Veronica Hardy are particularly relevant because both fights required Moura to maintain her performance over multiple rounds.
Moura’s UFC experience also means she should not be overwhelmed simply because O’Neill enters as the favorite.
The underdog has already dealt with the pace and physicality of UFC competition.
However, Moura’s most recent performance was a loss to Wang Cong.
That fight ended in a decision, and it followed a period in which Moura had dealt with weight-management issues. MMA Fighting noted that Moura has missed weight multiple times during her UFC tenure, including for the Wang Cong fight.
Those details add uncertainty to her current form.
Moura’s Best Path to Victory
Moura’s clearest path is to prevent O’Neill from dictating the pace.
If O’Neill is allowed to stand at range and accumulate significant strikes, the fight could become increasingly difficult for Moura.
Instead, Moura should look to close distance, force clinch exchanges and create grappling sequences.
Longer grappling exchanges could reduce O’Neill’s striking volume.
They could also make the fight more physically demanding and prevent O’Neill from settling into a consistent rhythm.
Moura also needs to be careful about giving O’Neill easy opportunities to reverse positions.
A failed takedown or prolonged clinch exchange could allow O’Neill to transition into a dominant position.
The underdog therefore needs controlled aggression rather than simply pushing forward.
Grappling Could Change the Fight
The striking matchup is important, but grappling could ultimately determine the result.
O’Neill has a well-rounded MMA game and has historically been comfortable mixing wrestling with striking.
If she can force Moura to defend takedowns, O’Neill can create additional opportunities on the feet.
The opposite is also true.
If Moura can consistently initiate grappling exchanges and keep O’Neill occupied against the fence, she can reduce the favorite’s striking output.
That is why the first round will be especially important.
If O’Neill establishes her preferred range immediately, Moura could spend much of the fight reacting.
If Moura successfully closes distance, the bout could become significantly more competitive.
Casey O’Neill vs Eduarda Moura Betting Prediction: Striking Matchup
The striking numbers provide one of the strongest reasons to side with O’Neill.
O’Neill has developed a reputation for exceptional activity. Her reported 7.89 significant strikes landed per minute demonstrates just how frequently she works offensively.
That activity can be valuable under the judging criteria because it allows her to generate consistent offense throughout each round.
Moura has the toughness to withstand pressure, but surviving an aggressive opponent is not the same as winning rounds.
Moura needs to answer O’Neill’s activity with effective offense of her own.
Simply backing up and absorbing combinations would make it difficult to win a decision.
The key question is whether Moura can create enough offensive moments to offset O’Neill’s volume.
Casey O’Neill vs Eduarda Moura Betting Prediction: Fight Pace
Fight pace should favor O’Neill.
She has shown a willingness to maintain a high work rate, and her significant-strike output supports that assessment.
Moura’s ideal fight would likely involve fewer extended striking exchanges and more clinch or grappling sequences.
That creates a tactical battle.
O’Neill wants space.
Moura wants to reduce it.
O’Neill wants repeated exchanges.
Moura wants to disrupt them.
The fighter who dictates where those exchanges take place should have a significant advantage.
If the fight stays at kicking and boxing range for long stretches, O’Neill’s activity should stand out.
If Moura repeatedly gets O’Neill against the fence, the underdog has a better chance of making the fight close.
Casey O’Neill vs Eduarda Moura Betting Prediction: Experience
Experience is relatively balanced in a different sense.
O’Neill has been through the UFC’s highest-pressure stages and has already experienced both winning streaks and adversity.
Moura has also faced established UFC opponents and has five UFC fights under her belt.
Neither fighter should be overwhelmed by the environment.
However, O’Neill’s recent momentum is notable.
She has won two straight after suffering consecutive defeats.
Moura, meanwhile, enters after a decision loss to Wang Cong.
That recent form gives O’Neill a statistical and momentum-based edge heading into UFC 331.
O’Neill’s Recent Finish Adds Another Dimension
The first-round TKO over Fernandes is important because it shows that O’Neill’s high-volume approach can produce a finish.
Before that victory, her most recent UFC win was a decision over Santos.
That combination makes her difficult to handicap.
She can win through sustained activity over three rounds, but she also has the ability to finish if her opponent begins taking too much damage.
For betting purposes, that makes the moneyline more attractive than trying to predict an exact method.
A decision prop may offer additional value if the price remains reasonable, but the safest projection is still O’Neill to win the fight.
Moura’s Losses Provide Useful Matchup Information
Moura has two UFC losses.
She lost a split decision to Denise Gomes and most recently lost a decision to Wang Cong.
Both results are useful when examining the matchup.
The losses demonstrate that Moura can struggle when facing opponents capable of consistently applying striking pressure.
That does not mean O’Neill will replicate either performance.
Every MMA matchup is different.
Still, O’Neill’s volume-based style creates a similar tactical question.
Can Moura generate enough offense to prevent O’Neill from controlling the scoring exchanges?
That may be the central question of the fight.
Casey O’Neill vs Eduarda Moura Betting Prediction: Moneyline Analysis
The current moneyline is approximately O’Neill -205 and Moura +170.
That pricing reflects O’Neill’s recent resurgence, her high-volume striking and her overall UFC experience.
The favorite’s price is not extremely short, which means there is still a meaningful underdog argument.
Moura is experienced and has already defeated established UFC competition.
However, the stylistic matchup favors O’Neill.
The favorite has more ways to win.
She can strike at range, pressure forward, mix in takedowns and potentially win a decision through sustained activity.
Moura’s path is narrower.
She needs to disrupt O’Neill’s rhythm and prevent the fight from becoming a high-volume striking contest.
For that reason, the preferred position is O’Neill on the moneyline.
Best Bet: Casey O’Neill Moneyline
Casey O’Neill vs Eduarda Moura Betting Prediction: Method of Victory
The most likely method of victory is a decision.
O’Neill’s striking volume gives her a strong path to winning rounds without needing a finish.
She also has recent evidence of finishing ability after stopping Fernandes in the first round.
Still, Moura has shown that she can survive against experienced opponents.
A three-round fight gives O’Neill enough time to accumulate significant strikes and potentially secure takedowns without needing to force a finish.
That makes a decision the preferred projected outcome.
Secondary Bet: O’Neill by Decision
The knockout remains a realistic alternative if Moura struggles to deal with O’Neill’s pace.
Casey O’Neill vs Eduarda Moura Betting Prediction: Round-by-Round Projection
Round 1
Expect O’Neill to establish her range early.
She should use movement and combinations to test Moura’s reactions.
Moura’s priority should be closing distance and preventing O’Neill from settling into a rhythm.
The first round could be competitive, but O’Neill’s activity gives her the early edge.
Projected Round 1: O’Neill
Round 2
The pace could become more important here.
If Moura has spent significant energy defending combinations and takedowns, O’Neill’s volume could begin to create separation.
Moura needs to make the fight physical and force clinch exchanges.
Projected Round 2: O’Neill
Round 3
If O’Neill is ahead entering the final round, she should continue mixing striking with grappling rather than searching aggressively for a finish.
Moura will likely need a strong final round to change the fight.
That could lead to increased exchanges late.
Projected Round 3: O’Neill
Projected Result: Casey O’Neill by Unanimous Decision
Why O’Neill Can Win
Several factors support O’Neill in this matchup.
1. Elite striking volume
O’Neill is reported to land approximately 7.89 significant strikes per minute.
2. Recent momentum
She has won two consecutive fights after suffering back-to-back defeats.
3. Recent finishing ability
O’Neill stopped Gabriella Fernandes by first-round TKO in March.
4. Multiple paths to victory
O’Neill can use striking, pressure and grappling rather than relying on one specific weapon.
5. Favorable recent matchup profile
Moura enters after losing decisions to Wang Cong and Denise Gomes, two opponents who were able to challenge her through striking.
Why Moura Can Pull the Upset
Moura should not be dismissed simply because she is the underdog.
She has already defeated Lauren Murphy and Veronica Hardy in UFC competition.
Her experience gives her a realistic path to making the fight difficult.
The biggest opportunity is grappling.
If Moura can repeatedly close distance and force O’Neill into clinches, she can limit the favorite’s striking volume.
She also needs to make O’Neill work for every exchange.
A slower, physical fight would benefit Moura more than an open striking contest.
If she can avoid taking sustained damage and win enough grappling exchanges, the +170 price becomes more relevant.
What Could Make the Fight Go Over Three Rounds?
A three-round decision is a realistic outcome because both fighters have demonstrated the ability to compete in extended UFC fights.
O’Neill has multiple decision victories on her UFC record.
Moura has also won and lost decisions against experienced opponents.
Neither fighter needs to force an early finish.
O’Neill can win by accumulating strikes.
Moura can try to disrupt that activity through clinches and grappling.
That creates a fight where three full rounds are more likely than an immediate finish.
The recent O’Neill knockout is the primary reason not to completely rule out a stoppage.
What Could Produce an Early Finish?
O’Neill’s striking volume could create a finishing opportunity if Moura absorbs too many clean shots.
The favorite has already demonstrated that possibility against Fernandes.
Moura could also create finishing opportunities of her own if she catches O’Neill during an aggressive exchange.
However, neither fighter should need to take unnecessary risks early.
The fight is scheduled for three rounds, giving both competitors time to make adjustments.
That makes a decision the more reasonable projected outcome.
Casey O’Neill vs Eduarda Moura Betting Prediction: Best Bet
The best bet is Casey O’Neill moneyline.
The current price around -205 reflects a matchup in which O’Neill has several advantages.
Her striking volume stands out.
Her recent form is strong.
She has won two consecutive fights and most recently produced a first-round TKO.
Moura has enough experience to make this competitive, but she needs to change the fight’s rhythm.
If O’Neill controls the distance and maintains her usual activity, she should have enough opportunities to win rounds.
The preferred result is O’Neill by decision.
Best Bet: Casey O’Neill Moneyline
Secondary Bet: Casey O’Neill by Decision
Projected Result: Casey O’Neill by Unanimous Decision
Casey O’Neill vs Eduarda Moura Betting Prediction: Final Fight Script
The opening minutes should feature O’Neill attempting to establish range while Moura looks for opportunities to close distance.
O’Neill’s activity should gradually become the defining feature.
Moura may have moments in the clinch and during grappling exchanges, but O’Neill should have more sustained offense.
By the second round, O’Neill’s ability to mix combinations with takedown attempts should make it increasingly difficult for Moura to dictate the fight.
The third round should be competitive if Moura remains durable.
However, O’Neill’s volume should allow her to finish strongly.
The final scorecards could favor O’Neill across all three rounds.
Projected Result: Casey O’Neill by Unanimous Decision
Key Factors to Watch
O’Neill’s Significant-Strike Volume

Takedown Success

O’Neill’s Pace

Moura’s Durability
If Moura can absorb O’Neill’s early pressure, the fight becomes more dependent on adjustments and late-round execution.
