December has become one of the richest months for sports betting. Across basketball, NFL football, MMA, tennis, and soccer, major tournaments and high-stakes matchups all land within weeks, delivering knockout rounds, playoff-push games, international tournaments, and congested club schedules. Whether you prefer long sessions of props and live bets or quick, high-impact plays, December offers something for most bettors.
Here are the top leagues and events worth your attention this month, and what we think matters most when placing bets.

Basketball
NBA Cup Quarterfinals, Semifinals & Final
The second edition of the Emirates NBA Cup reaches its knockout stage this December. Quarterfinals are early in the month, with semifinals set for December 14 and the Final scheduled in Las Vegas on December 17.
These Cup games feel different from regular season nights. Coaches shorten rotations, stars play heavier minutes, and teams treat it almost like postseason dress rehearsal. That typically creates tighter spreads and clearer usage patterns. Good betting angles include:
- Star player points or combo props (points + rebounds or assists), since top players log heavy minutes.
- Moneyline or spread bets on teams with deep benches and strong two-deep, because fatigue and shorter rotations favor depth.
- Unders on bench/role-players’ props — “garbage time” is much more limited when games are meaningful.
NBA Cup Semifinals & Final
As the tournament narrows, you often see slowed pace, more half-court sets, and less blowout potential. That can create value in:
- Total points unders when two defensively disciplined teams meet.
- Veteran guards controlling tempo — their tendencies are more predictable, which reduces variance.
- Live betting once adjustments become obvious (for instance, if a team switches to physical defense or slows pace after the first quarter).
NBA Christmas Day Games
Just a week after the Cup Final, the NBA drops its traditional Christmas Day slate with several marquee matchups built around rivalries and star power. These games typically draw lots of attention, and the betting market gets crowded — which sometimes opens up value for sharp bettors. We like watching for:
- Underdog value on well-coached road teams, especially those with physical defense.
- Role players stepping up — in tight rotations, some lesser-known players shock if they get extended minutes.
- Second-half totals when the first quarter opens slow or low scoring (often due to nerves and pressure).
All told, December basketball gives you high-stakes intensity and marquee games in a single month — perfect for player props, live moves, and spread/total plays.
American Football
NFL Weeks 13–17 (Playoff Push / Final Stretch)
By December, the NFL’s biggest stories begin to unfold. As the regular season nears its end, playoff races tighten, with seeding, wild-cards, and tiebreakers all coming into play. Motivation becomes clearer than early season games, which helps sharpen lines.
Among the angles worth tracking:
- Conference games with direct playoff implications — winners stay alive, losers risk elimination.
- Weather-affected totals and pass/run mix bets, especially for games in cold, rainy, or windy cities late in the season.
- Injuries and rotations — teams with nothing left to play for may rest starters, while desperate teams might overextend. That can lead to value picks on underdogs or totals unders.
Bills vs Eagles — December 28
One of the most anticipated late-season games is the Buffalo Bills vs Philadelphia Eagles at Highmark Stadium on December 28. With playoff implications, cold weather, and both teams likely in contention, this matchup offers interesting betting dynamics:
- Totals could be heavily influenced by wind and snow — pass-heavy offenses may shift to rush-heavy game plans, which can depress point totals.
- Quarterback rushing props become more relevant when throwing conditions deteriorate.
- Spread movement can be sharp if injury news or weather reports change in the days leading up to the game.
In December, NFL betting becomes less about guessing talent and more about reading urgency, health, and conditions.
MMA & Combats
UFC 323 — December 6
The UFC 323 card lands at T-Mobile Arena early in December, headlined by a rematch between Merab Dvalishvili and Petr Yan for the bantamweight title, with another top-level fight between Alexandre Pantoja and Steve Erceg as co-main.
This card is particularly attractive for bettors because:
- It features full five-round fights where cardio and pace often decide the outcome far more than sheer power.
- The fighters involved are well known, which draws a broad betting audience and sometimes leads to mispriced lines.
- There are strong live-betting opportunities — once you see who’s dictating pace or imposing their game plan, the value can shift notably.
PFL MENA 4 — December 5
The PFL MENA 4 event in Khobar, Saudi Arabia crowns champions across four weight classes. Tournament finals tend to reward consistency and discipline over chaotic styles. Betting opportunities we like:
- Fighters with reliable wrestling or grappling advantage — control and ground game often win in finals.
- Decision props when both fighters already have tiring schedules or previous fights in the season, which increases the chance of rounds going the distance.
- Value on underdogs who bring high-volume striking or cardio — if favorites misjudge pace, upsets can happen.
PFL Europe 4 Finals — December 13
The 2025 European season finale of the PFL lands in Lyon with a card headlined by Vadim Nemkov vs Renan Ferreira — and also featuring veteran star Cris Cyborg. Because styles are well documented and fighters are experienced, this card is ideal for bettors who do deep tape work.
It often pays to bet on:
- Style clashes where wrestler vs striker matchups have known tendencies.
- Round props when pace is slow, or when fight history suggests grappling will dominate.
- Live betting once early rounds reveal control — many fights shift after the first round in tournaments like this.
Abu Dhabi Grand Prix & Combat Weekend — December 7
While not strictly MMA, the Formula 1 Abu Dhabi Grand Prix at Yas Marina Circuit adds crossover appeal for bettors who follow multiple sports. Even though Lando Norris’ title is already sealed, you’ve predictable night-race settings and with stable track conditions, you’ve got one final big motorsport betting opportunity of the year. For those who mix UFC/PFL bets with motorsport, it’s a nice way to diversify risk.
Tennis
Next Gen ATP Finals in Jeddah — December 17–21
The 2025 Next Gen ATP Finals showcase runs on indoor hard courts in Jeddah with eight of the top under-20 players on the ATP Tour. The field includes rising talents such as Jakub Mensik and Learner Tien.
What makes this event a unique betting opportunity:
- Format uses short sets (first to four games), which increases unpredictability — upsets are more common, and underdogs have real value.
- Indoor conditions remove weather-related variables, so matchups and playing style dominate outcomes — a good advantage if you follow Challenger-level results.
- Live betting can pay off fast — short sets, break or service swings, and momentum shifts give room for turnaround between points or games.
For bettors who follow up-and-coming players, Next Gen Finals offers value before public attention peaks.
Soccer
2025 Africa Cup of Nations (AFCON) in Morocco — December 21 onward
The 2025 Africa Cup of Nations kicks off in Morocco on December 21, running through January 18, 2026. It includes 24 national teams fighting across nine stadiums for continental glory.
This year’s timing hits right during a busy club season. Many top players from African nations will leave European leagues mid-season to represent their countries. With players from major league across Europe involved, there are some interesting betting propositions:
- Directly, for bets on AFCON matches themselves — early group games tend to be cautious and low scoring, but group stage dynamics often open up in later rounds if teams need goals.
- Indirectly, for domestic leagues (especially EPL and EFL). Clubs losing key African internationals often suffer dips in form, defense, or attacking output — which can create value on underdog or overs/unders markets.
UEFA Champions League — Final League Phase Matchdays
The 2025–26 Champions League reaches its final group phase matchdays in early December. Clubs fighting for qualification or better seeding often approach these games with urgency, which tends to produce open, attacking football and higher-scoring matches.
For bettors, that suggests value in:
- Both-Teams-Score (BTTS) markets when two sides need goals for qualification.
- Live totals once game state becomes clear (for example, if a side needs two or three goals late in the game).
- Booking or card markets — pressure, stakes, and rivalries often lead to fouls and tension.
UEFA Europa League
Europa League bouts face similar dynamics. Many clubs juggle heavy domestic schedules plus European commitments. The key to smart betting is understanding which competition matters more to each club. Teams prioritizing domestic league survival or promotion may underperform in Europe — and vice versa.
Premier League December Schedule & EFL Congestion
The English top flight enters a congested schedule in December, with multiple midweek and weekend games. That creates several betting considerations:
- Rotation risk — clubs often rest players or rotate heavily, which makes form volatile and lineups unpredictable.
- Fatigue, especially for high-pressing, attack-heavy teams, which may struggle to maintain intensity late in the month.
- Value opportunities for deeper squads — clubs with larger rosters may overperform when rotation hits.
Meanwhile, in the lower leagues (EFL), Boxing Day and late-December fixtures often see sharper market movements because injury news and squad depth are less transparent. That lack of clarity can create value for bettors who track reports closely.
