The Fight to Legalize Bare Knuckle Boxing: State-by-State History
The legalization of bare knuckle boxing in the United States is one of the most remarkable regulatory stories in modern combat sports. What was once universally banned has become legal in over 30 states in less than a decade. This is the story of how it happened.
The Pre-History: 1889-2017
The last widely recognized legal bare knuckle prizefight in America took place on July 8, 1889, when John L. Sullivan defeated Jake Kilrain in 75 rounds in Richburg, Mississippi. After that, the adoption of the Marquess of Queensberry rules made gloved boxing the only sanctioned form of the sport.
For 129 years, bare knuckle fighting existed exclusively in the underground — in barns, backyards, and parking lots. While it never disappeared from American culture, it had no legal path forward.
Phase One: The Breakthrough (2018)
Wyoming — June 2018
The Wyoming Combat Sports Commission became the first regulatory body to sanction a bare knuckle fighting event when BKFC held its inaugural card in Cheyenne.
Key factors in Wyoming's decision:
- Small commission willing to innovate
- Strong safety proposal from BKFC
- No explicit statutory prohibition on bare knuckle fighting
- Economic interest in hosting a novel sporting event
Mississippi — August 2018
Mississippi became the second state, hosting BKFC 2 in Biloxi. The state's athletic commission had a history of embracing combat sports events.
Phase Two: Southern Expansion (2019-2020)
The early momentum built quickly across southern and western states:
| State | Year | Key Advocate | Notes |
|---|---|---|---|
| Florida | 2019 | BKFC, local promoters | Major market breakthrough |
| Alabama | 2019 | Athletic commission | Quick approval process |
| Montana | 2019 | Legislative supporters | Rural state, combat sports culture |
| South Dakota | 2019 | Commission initiative | Minimal opposition |
| New Hampshire | 2019 | Bipartisan support | First northeastern state |
| Colorado | 2020 | DORA regulatory review | Progressive approach |
| Georgia | 2020 | Athletic commission | Growing MMA market helped |
| Tennessee | 2020 | Legislative action | Nashville event demand |
| Louisiana | 2020 | State athletic commission | Boxing tradition state |
| Missouri | 2020 | Office of Athletics | St. Louis market |
Phase Three: Mainstream Acceptance (2021-2023)
As the sport's safety record proved solid and economic benefits became clear, a second wave of states moved toward legalization:
The passage of the ABC unified rules in 2024 was foreshadowed by growing ABC member interest during this period. States that had been hesitant could now point to a standardized framework.
Texas (2022)
Texas was a major win. The Texas Department of Licensing and Regulation approved bare knuckle fighting after extensive review. Access to Dallas, Houston, San Antonio, and Austin transformed the sport's commercial landscape.
Nevada (2022)
The Nevada State Athletic Commission — the most prestigious regulatory body in combat sports — sanctioning bare knuckle fighting was a watershed moment. Las Vegas events brought mainstream media coverage and celebrity involvement.
Pennsylvania, Ohio, North Carolina (2023)
Three major population states approving bare knuckle fighting in the same year demonstrated unstoppable momentum.
Phase Four: The ABC Unified Rules and Beyond (2024-2026)
The ABC's adoption of unified rules in 2024 accelerated the remaining holdout states. States no longer needed to develop their own regulatory framework from scratch — they could adopt the unified rules wholesale.
States that legalized in 2024-2026:
- Utah, Arkansas, Virginia, West Virginia (2024)
- Michigan, Illinois, Minnesota (2025)
The current state-by-state map shows the full picture as of 2026.
The Opposition
Not every state has embraced bare knuckle fighting. Opposition has come from several sources:
Medical Associations
State medical associations in New York, Massachusetts, and California have lobbied against legalization, citing concerns about:
- Hand fractures and metacarpal injuries
- Facial lacerations requiring sutures
- Traumatic brain injury
- Inadequate long-term health data
Political Opposition
Legislators in several states have introduced bills to explicitly ban bare knuckle fighting, viewing it as a step backward in combat sports safety.
Boxing Establishment
Traditional boxing interests have sometimes opposed bare knuckle legalization, viewing it as competition for fighters, fans, and commission attention.
The Arguments That Won
Advocates for legalization consistently made several compelling arguments:
- Harm reduction — Legalization allows for medical oversight, drug testing, and safety standards that underground events lack
- Economic benefits — Events generate tax revenue, tourism spending, and jobs
- Fighter safety data — Emerging evidence suggests bare knuckle fights may produce fewer concussions than gloved boxing, as fighters punch with less force to protect their hands
- Personal freedom — Consenting adults should be allowed to participate in regulated combat sports
- MMA precedent — The successful legalization and regulation of MMA provided a roadmap
What Remains
As of 2026, the major holdout states are:
- New York — Strong political opposition and a powerful state athletic commission that has resisted
- California — A bill is in committee, and legalization is expected
- Massachusetts — Medical community opposition remains strong
- Connecticut — No enabling legislation has been introduced
The IBA's embrace of bare knuckle boxing in 2025 and the sport's continued growth on streaming platforms suggest that full nationwide legalization is a matter of when, not if.
