2026 RIZIN Betting Trends

2026 RIZIN betting trends: Favorites are 34-17 through 51 betting-eligible fights after going 10-1 at Landmark 15, but they remain slightly negative at -1.76 units.

2026 RIZIN Betting Trends at a Glance

Bet Type	Record	Units	ROI
Favorites	34-17	-1.76	-3.4%
Underdogs	17-34	-5.32	-10.4%
Over	28-23	-8.05	-15.8%
Under	23-28	-5.81	-11.4%

Landmark 15 changed the broad 2026 moneyline picture. Favorites entered the event down 5.37 units, then went 10-1 for +3.61 units and +32.8% ROI on the card. That cut the full-year favorite loss to 1.76 units.

Underdogs moved in the opposite direction. Dogs had been profitable through June 6, but a 1-10 Landmark 15 result dropped the full-year record to 17-34 for -5.32 units and -10.4% ROI.

Landmark 15 Flipped the 2026 Totals Picture

The Under went 7-4 at Landmark 15 for +6.51 units and +59.2% ROI, the most profitable broad market on the event. Even with that result, both totals sides remain negative across the full 2026 sample.

Overs are 28-23 for -8.05 units and -15.8% ROI in 2026. Unders are 23-28 for -5.81 units and -11.4% ROI. The event reinforced why RIZIN totals are more useful when separated by division rather than treated as one promotion-wide market.

RIZIN Betting Trends Since 2025

Market	Record	Units	ROI
Favorites	99-55	-11.98	-7.8%
Underdogs	55-99	+2.78	+1.8%
Over	97-57	+14.46	+9.4%
Under	57-97	-45.89	-29.8%

The longer post-2024 sample still shows why underdogs and Overs remain worth tracking, even after a poor Landmark 15 card for both markets. Since the beginning of 2025, underdogs are still slightly profitable at +2.78 units, while favorites have lost 11.98 units. Overs remain the strongest broad market over that same period at +14.46 units and +9.4% ROI.

Bantamweight Underdogs Still Lead the 2026 Moneyline Trends

RIZIN Bantamweight underdogs remain the strongest profitable 2026 moneyline trend among the established divisions. Dogs are 6-5 for +3.56 units and +32.4% ROI. The record is no longer as extreme as it was before Landmark 15, but the division continues to reward underdog prices more than the full historical sample suggests.

Featherweight underdogs are also profitable in 2026 at 4-6 for +2.31 units and +23.1% ROI. Since 2025, Featherweight dogs are 14-21 for +5.88 units and +16.8% ROI.

Lightweight Favorites Improve to 8-1

Johnny Case’s win at Landmark 15 pushed RIZIN Lightweight favorites to 8-1 in 2026 for +2.47 units and +27.4% ROI. The division remains highly volatile across seasons. Favorites dominated 2024, underdogs produced the strongest return in 2025, and favorites have moved back to the front in 2026.

The 2026 Lightweight Over has cooled after the Landmark 15 Under. Overs are now 6-3 for +0.70 units and +7.8% ROI, while Unders are 3-6 for -3.87 units and -43.0% ROI.

Flyweight Overs Reach 29-9 Since 2024

Men’s Flyweight remains the strongest sustained totals division in the RIZIN database. Both Landmark 15 Flyweight fights went Over, pushing the full 2024-2026 record to 29-9 for +9.70 units and +25.5% ROI.

Since the beginning of 2025, Flyweight Overs are 22-5 for +6.82 units and +25.3% ROI. In 2026 alone, the Over is 7-2 for +1.50 units and +16.7% ROI.

Catchweight Overs Remain One of RIZIN’s Best Recent Trends

Shoji Maruyama’s decision win over Genji Umeno sent their Catchweight bout Over 1.5 rounds. Men’s Catchweight Overs are now 9-5 for +6.01 units and +42.9% ROI since 2025.

Catchweight underdogs have also remained profitable. Dogs are 8-9 for +3.24 units and +19.1% ROI since 2024, while the narrower coin-flip underdog sample is 4-2 for +60.0% ROI since 2025.

Atomweight and Welterweight Trends After Landmark 15

Women’s Atomweight favorites improved to 13-2 for +1.43 units and +9.5% ROI since 2024 after Saori Oshima and Si Woo Park both won at Landmark 15. The more interesting 2026 development is the Under, which is 3-3 but has returned +1.59 units and +26.5% ROI because of the prices attached to the winning totals.

The RIZIN Men’s Welterweight sample remains extremely small, but favorites are now 2-0 for +0.83 units and +41.7% ROI since 2024 after Yota Rice Hayashi defeated Shinji Sasaki.

2026 RIZIN Betting Trends Summary

Landmark 15 pulled the broad 2026 favorite market close to break-even and erased the earlier overall underdog profit. The strongest current betting trends are now more concentrated by division than by promotion-wide market.

Bantamweight underdogs and Lightweight favorites lead the 2026 moneyline trends, while Men’s Flyweight Overs remain the strongest sustained totals trend in the database. Catchweight Overs also continue to return strong profits over the post-2024 period.
