About

Combat Odds is an independent MMA betting data and analysis project covering UFC and RIZIN. We track fight-level results, closing odds and market performance to show which betting trends have actually produced profits and losses over time.

What We Do

Combat Odds builds historical betting databases and turns them into public-facing analysis. Our coverage focuses on the markets MMA bettors actually use: moneylines, totals, distance markets where reliable pricing is available, method props, divisional splits and event-level results.

The goal is simple: separate real historical performance from assumptions. A favorite can win most of its fights and still be a losing bet. An underdog trend can have a losing record and still produce a positive return. We publish the record, units and ROI so readers can see the full picture.

Current Coverage

• UFC — historical betting trends, annual summaries and division-level analysis built from a database extending back to 2015.
• RIZIN — event results, predictions and betting trends using a separately maintained RIZIN database covering the available modern tracking period.

Other promotions will only be added to the public site when there is enough verified data and active content to support them. We do not create empty sections simply to make the site look larger.

How Combat Odds Is Different

• Fight-level tracking — trends are built from individual fights rather than broad narratives.
• Real market prices — returns are calculated against tracked closing odds rather than assuming every bet is priced the same.
• Open methodology — our calculation rules, exclusions and limitations are documented publicly.
• Sample-size context — small samples are identified rather than presented as permanent laws.
• No invented data — unavailable markets are not silently treated as losses, and reconstructed or estimated values are identified when they are used.

What the Numbers Mean

Combat Odds is a historical analysis project, not a guarantee of future outcomes. Betting markets change, divisions evolve and a profitable past trend can disappear. The value of the database is that readers can see what actually happened, at what price, across a clearly defined sample.
