Passed the House, received in Senate
The fighters take the hits. This sets their floor.
Why it matters
$200 per round. $50,000 in medical coverage. Brain exams after every knockout. H.R. 4624 would set a national floor for how professional boxers are paid and protected when they sign with a new kind of league called a unified boxing organization. It also caps those contracts at 6 years and limits each weight class to a single championship belt.
H.R. 4624, the Muhammad Ali American Boxing Revival Act of 2026, creates a new lane in professional boxing called a unified boxing organization, or UBO. A UBO is a private league that signs boxers to contracts and runs its own matches, rankings, and title belts instead of leaning on outside sanctioning bodies. In exchange for that control, a UBO has to meet a long list of safety, pay, and conduct standards.
On safety, the bill stacks new protections on top of existing federal boxing law. A fighter who gets knocked out has to pass extra brain-health exams before the next match. Boxers age 40 and older need an annual physical with bloodwork, plus a chest X-ray at least every 6 years. Every covered match needs a second ambulance on site and a second physician at ringside, and within two years those ringside doctors have to be certified through a national program.
On money, the bill guarantees at least $200 per round. A boxer also has to be given either one match every 6 months or a payout worth at least 10 times that round rate, which works out to a $2,000 floor at the minimum. Contracts can't run longer than 6 years, and in the final 30 days a fighter is free to talk to other promoters and leagues. Promoters or UBOs have to carry at least $50,000 in medical coverage and $15,000 in accidental-death coverage, and they can't bill the fighter for the premiums.
The bill also goes after the sport's biggest source of confusion: too many belts. Inside the UBO system, each weight class gets one champion, with interim titles allowed only for narrow reasons like injury or an inability to defend. Drug testing expands too. Every title fight is tested, other fights face random testing, and at least half the boxers at any event get tested by an independent lab.
Congress frames all of this as a safety problem. The bill's findings argue that uneven standards across state boxing commissions have allowed dangerous matches that left fighters seriously injured or killed, and that a national model code would close those gaps.
H.R. 4624 Bill Summary
What H.R. 4624 actually does.
Knockouts trigger brain exams before a return
A boxer who is knocked out during a covered match would have to complete additional brain-health examinations before being cleared for the next one.
Older fighters get extra annual screening
Boxers age 40 and older would need a yearly supplemental physical that includes a comprehensive metabolic panel and urinalysis, plus a chest X-ray at least once every 6 years.
Every event gets more emergency medical coverage
A UBO would have to provide at least one extra ambulance on site and one extra licensed physician at ringside for each covered match, and within two years those physicians must be certified through a national program.
Boxers get a national pay floor
Contracts would have to guarantee at least $200 per round, plus either one match every 6 months or a payout worth at least 10 times the minimum round rate.
Boxing contracts get a time limit
A UBO contract could not run longer than 6 years, and during the final 30 days the boxer is free to talk with other promoters or leagues.
Promoters have to carry real insurance
A promoter or UBO would have to provide at least $50,000 in medical coverage and $15,000 in accidental-death coverage, and the boxer could not be charged for the premiums.
One championship belt per weight class
Inside the covered system, only one championship title is allowed in each weight class, with interim titles limited to cases like an injured or unavailable titleholder.
Drug testing expands beyond title fights
Title matches would require testing, other matches would face random testing, and at least half the boxers at each event would be tested in competition by an independent third party.
Who benefits from H.R. 4624?
Professional boxers who sign with a UBO
They would get a guaranteed pay floor, a 6-year cap on contracts, freedom to shop themselves near the end of a deal, and insurance that includes at least $50,000 in medical coverage they don't pay for.
Fighters coming back from a knockout
They would have to clear mandatory brain-health exams before stepping back into a covered match, rather than relying on whatever standard a promoter or commission happens to apply.
Boxers still competing at 40 and up
They would get extra annual screening, including bloodwork and periodic chest X-rays, meant to catch health problems before the next fight.
Fans trying to follow who the real champion is
Inside the covered system they would see one belt per weight class instead of competing titles, because the bill allows a single championship per division and sharply limits interim belts.
Boxers competing clean
They would fight under broader anti-doping rules, including mandatory testing for title fights and independent testing of at least half the boxers at every event.
Who is affected by H.R. 4624?
Unified boxing organizations
They would carry the heaviest compliance load: more medical staff and ambulances, an anti-doping program, training-injury insurance, support services, FTC filings, and the new title rules.
Promoters
They would have to provide the required insurance, operate under the contract and pay standards, and follow expanded testing and officiating rules for covered matches.
Existing sanctioning bodies
The one-belt-per-weight-class rule and the UBO model would reshape how titles are awarded inside the covered system, cutting into a business built on multiple competing championships.
UBO officers and employees
A willful and knowing violation could bring up to 1 year in prison, a fine of up to $20,000, or both.
Fighters, coaches, trainers, and household members
The bill's conduct policy would bar them from betting on covered matches or leaking non-public information to help someone else place a bet.
