The legal landscape for competitive slap fighting in the United States is a patchwork of prohibitions, refusals to sanction, active regulation, and regulatory silence. Alabama prohibits it by athletic commission rule. Nevada and California have both sanctioned it. Colorado, Connecticut, and Kentucky have been reported as declining to sanction events. And the majority of states have not taken a clear public position, leaving the format in regulatory gray areas. Here is the 2026 breakdown, with the confirmed positions separated from the reported ones.
States That Have Banned or Refuse to Sanction
Prohibition
| State | Action | Date | Details |
|---|---|---|---|
| Alabama | Athletic commission rule | October 2022 | The Alabama Athletic Commission has treated slap fighting as prohibited since October 2022. A bill to write the ban into statute — SB7 of the 2026 Regular Session, sponsored by Sen. Gerald Allen — was introduced 13 January 2026 and indefinitely postponed on 7 April 2026. There is no statutory ban. |
The Alabama correction matters because a great deal of early-2026 coverage announced that the state had moved to permanently ban slap fighting. The bill died. The commission-level prohibition is what remains in force.
Commissions Reported as Refusing to Sanction
These states have not passed legislation banning slap fighting; their athletic commissions have been reported as declining to sanction or regulate events. We have not verified each of these against a commission record, and they should be treated as reported rather than confirmed:
| State | Commission Position |
|---|---|
| Colorado | Reported as declining to sanction |
| Connecticut | Reported as declining to sanction |
| Kentucky | Reported as declining to sanction |
| Michigan | Reported as unable to sanction absent promulgated rules of engagement under the Unarmed Combat Regulatory Act |
The distinction between a legislative ban and a commission refusal matters: a legislative ban makes the activity illegal, while a commission refusal means the format is simply unregulated, potentially leaving room for unsanctioned events in some legal interpretations. That gap is not theoretical — the only clinical case report in the medical literature describes a jaw fracture sustained in an unofficial, unsanctioned amateur slap bout, covered in our page on the medical evidence on slap fighting.
States That Have Sanctioned Slap Fighting
Actively Regulated
| State | Status | Key Events |
|---|---|---|
| Nevada | NSAC voted unanimously on 18 October 2022 that slap fighting qualifies as unarmed combat under NRS 467.0107 and falls under its jurisdiction | Multiple Power Slap cards in Las Vegas |
| California | CSAC approved sanctioning on a 6-0 vote at its meeting of 9 December 2023, reported as a conditional licence with rules still to be written | Approved alongside bare knuckle in the same session |
Nevada's decision to sanction Power Slap was controversial. The Nevada State Athletic Commission (NSAC), one of the most prominent in the country, argued that regulation was preferable to prohibition because it imposed safety standards, medical requirements, and oversight.
California's approval in December 2023 was more contested still. The vote was taken on a Saturday morning, the meeting was not made available to the public in audio or video form, and critics accused the commission of chasing event revenue. It is nonetheless a sanction, and any page still describing California as a state that refuses to regulate slap fighting is out of date.
Other States with Events
Several states have hosted slap fighting events through various regulatory pathways:
- Some states approved events under existing combat sports frameworks
- Tribal lands have hosted events under sovereign regulatory authority
- Some events operated in regulatory gaps before commissions addressed the format
The Regulatory Arguments
Why States Ban or Refuse
State regulators and legislators cite several reasons for opposing slap fighting:
- Neuroscience evidence: Dr. Omalu and other neuroscientists argue the format is inherently brain-damaging, and the published medical evidence — a JAMA Surgery research letter and a 2025 case report — is now citable at commission hearings
- No defensive component: Unlike boxing or MMA, competitors cannot defend themselves
- Public safety concern: Potential for imitation, particularly by young people
- Medical liability: Commissions may be liable for sanctioning events that produce preventable brain injuries
- Death of Artur Walczak: Cited as evidence of fatal risk
- Political pressure: Constituent and advocacy group opposition
Why States Sanction
Regulators who sanction slap fighting argue:
- Regulation is better than prohibition: If people will do it anyway, oversight improves safety
- Consenting adults: Participants choose to compete with informed consent
- Economic benefit: Events generate revenue, jobs, and tax income
- Consistency: If boxing and MMA are legal, slap fighting should be too
- First Amendment: Some argue competitive slap fighting is protected expression
State-by-State Breakdown
Categories
Banned: Slap fighting is explicitly prohibited by law
Will not sanction: Athletic commission has declined to regulate or approve events
Sanctioned/Regulated: Commission has approved and regulated slap fighting events
No clear position: State has not publicly addressed slap fighting regulation
| Category | States |
|---|---|
| Prohibited (commission rule) | Alabama |
| Will not or cannot sanction (reported) | Colorado, Connecticut, Kentucky, Michigan |
| Sanctioned | Nevada, California |
| No clear position | Remaining states |
The "no clear position" category is by far the largest, reflecting how new slap fighting is as a regulated competitive format. Anyone publishing a complete fifty-state table on this topic is inferring, not reporting: only a handful of jurisdictions have taken a documented, dateable position.
Comparison to Bare Knuckle Regulation
The slap fighting regulatory map mirrors the earlier experience of bare knuckle boxing:
| Phase | Bare Knuckle (Historical) | Slap Fighting (Current) |
|---|---|---|
| Initial response | Almost universally banned or unregulated | Mix of bans and lack of regulation |
| First sanction | Wyoming (2018) | Nevada (October 2022) |
| Current status | Sanctioned in many states | Confirmed sanctioned in two |
| Trajectory | Growing acceptance | Uncertain; growing opposition |
The key difference: bare knuckle fighting gained acceptance partly because data showed lower concussion rates than boxing. Slap fighting faces the opposite challenge: neuroscience data argues against it.
What Comes Next
Potential Federal Action
If state-by-state regulation is deemed insufficient, federal action could include:
- Federal legislation banning competitive slap fighting nationwide
- FCC regulation restricting broadcast of slap fighting events
- Federal commission oversight similar to professional boxing's Muhammad Ali Boxing Reform Act
- Congressional hearings with neuroscientist testimony
Industry Adaptation
The slap fighting industry is responding to regulatory pressure by:
- Improved medical protocols at sanctioned events
- Lobbying efforts in states considering regulation
- Research funding to counter neuroscience criticism
- Self-regulation through internal safety standards
- International events in jurisdictions with less opposition
