New Underground Fighting Organizations to Watch in 2026
The underground fighting landscape never stops evolving. While established organizations like KOTS and Streetbeefs dominate, a new wave of promotions is emerging with fresh formats, untapped markets, and innovative approaches. These are the organizations most likely to make an impact in 2026.
For the established hierarchy, see our top 10 underground fighting organizations.
1. Blood4Blood Festival
Base: Europe (various) | Format: Multi-organization festival | Launched: 2025
Blood4Blood is not a single promotion but a festival concept that brings multiple underground fighting organizations together for a single mega-event. Think of it as Coachella for combat sports. Their 2026 festival promises fighters from KOTS, Top Dog FC, and several smaller European promotions competing on one card.
Why watch: Cross-promotional matchups that fans have dreamed about. The festival format is unique in the space.
Potential: Very high. If executed well, Blood4Blood could become the biggest annual event in underground fighting.
2. Nordic BK (Nordic Bare Knuckle)
Base: Stockholm, Sweden | Format: Bare knuckle boxing | Launched: 2024
Scandinavia's bare knuckle boxing scene is underserved despite strong martial arts culture. Nordic BK fills that gap with events that blend professional bare knuckle boxing with the Nordic aesthetic. Their debut events in 2024-25 showed promising production quality and matchmaking.
Why watch: Clean production, tough Scandinavian fighters, and a growing Nordic combat sports fanbase.
Potential: Moderate to high. Could become the BKFC of Northern Europe.
3. Knuckle Kings
Base: Manchester, UK | Format: Bare knuckle boxing | Launched: 2023
Manchester's combat sports scene is among the richest in Europe, and Knuckle Kings taps into that tradition. Their events feature local talent from the Manchester boxing scene competing in bare knuckle formats. The promotion has grown quickly by focusing on authentic Northern English fight culture.
Why watch: Raw Manchester fight culture, competitive matchups, strong local following.
Potential: Moderate. Must compete with established UK promotions.
4. BK Brazil
Base: Sao Paulo, Brazil | Format: Bare knuckle boxing | Launched: 2024
Brazil's combat sports heritage is unmatched, and BK Brazil brings bare knuckle boxing to a country that already loves fighting. The promotion draws from Brazil's deep pool of boxing and MMA talent. Events in Sao Paulo and Rio have attracted growing audiences.
Why watch: Brazilian fighters bring unique style and toughness. The energy at events is electric.
Potential: Very high. Brazil's market size and fight culture make this a potential major player.
5. African BK Championship
Base: Johannesburg, South Africa | Format: Bare knuckle boxing | Launched: 2024
South Africa has a rich boxing tradition, and the African BK Championship aims to bring bare knuckle boxing to the continent beyond traditional Dambe and Musangwe. Their events feature fighters from across Southern Africa competing under modified bare knuckle rules.
Why watch: Untapped talent pool, unique cultural context, potential to grow across the African continent.
Potential: Moderate. Infrastructure and sponsorship challenges exist, but the talent is there.
6. Polish BK Federation
Base: Warsaw, Poland | Format: Bare knuckle boxing/MMA hybrid | Launched: 2023
Poland has embraced combat sports more enthusiastically than almost any European country, with KSW (MMA) leading the way. The Polish BK Federation capitalizes on this appetite with bare knuckle events that draw from Poland's deep combat sports talent pool.
Why watch: Polish fighters are tough and technical. The fanbase is dedicated and growing.
Potential: High within Poland, moderate internationally.
7. Bare Knuckle Italia
Base: Milan, Italy | Format: Bare knuckle boxing | Launched: 2024
Italy's connection to combat sports runs deep through boxing tradition, and Bare Knuckle Italia brings that heritage into the modern bare knuckle era. Events have been held in historic venues that add an atmospheric element unique in the sport.
Why watch: Italian boxing technique adapted for bare knuckle, beautiful venues, growing media interest.
Potential: Moderate. Italy's regulatory environment could be an obstacle.
8. Lethwei FC International
Base: Global (from Myanmar) | Format: Lethwei | Launched: 2023
Lethwei FC is expanding beyond Myanmar to bring the Art of Nine Limbs to international audiences. Their 2026 plans include events in Thailand, Singapore, and possibly the United States. The headbutt-legal format creates uniquely violent spectacle.
Why watch: Lethwei is the most brutal striking art in the world. International expansion opens it to new audiences.
Potential: Moderate. Cultural barriers and safety concerns may limit growth in some markets.
9. Northern BK (Canada)
Base: Alberta, Canada | Format: Bare knuckle boxing | Launched: 2024
Canada's bare knuckle scene was virtually nonexistent until Northern BK launched in Alberta. Drawing from Western Canada's tough, blue-collar fight culture, the promotion has staged several successful events in Calgary and Edmonton.
Why watch: Canadian fighters bring hockey-tough mentality to bare knuckle. Untapped market potential.
Potential: Moderate. Canada's regulatory landscape is relatively favorable for combat sports.
10. Vale Tudo Revival
Base: Rio de Janeiro, Brazil | Format: Vale Tudo (minimal rules MMA) | Launched: 2023
A deliberate callback to Brazil's legendary no-holds-barred fighting tradition, Vale Tudo Revival operates in the gray area between sanctioned MMA and underground fighting. Events feature minimal rules, small gloves, and a format that honors vale tudo's history.
Why watch: Historical significance, Brazilian jiu-jitsu legends involved in promotion, raw fighting action.
Potential: Moderate. Legal challenges and safety concerns are ongoing.
