The statement came from UFC chief business officer Hunter Campbell. The message was sent to all athletes and their managers.

Sports betting is now legal in more than 30 states.

Below is the complete statement from the UFC’s Campbell:

“We are writing to advise you of a change to the UFC Athlete Conduct Policy to which each UFC athlete subscribes under our Promotion Agreement and/or Ancillary Rights Agreement. As you know, the UFC Athlete Conduct Policy requires UFC’s contracted athletes to act in a legal, ethical, and responsible manner and avoid conduct detrimental to the integrity of the UFC organization. In light of clear direction that we have received from regulators responsible for the regulated sports betting industry in the United States, we are compelled at this time to recognize in the UFC Athlete Conduct Policy certain restrictions relating to wagering by our athletes, members of their teams and certain others.

As you may already be aware, most states in which regulated sports betting is conducted prohibit athletes from wagering on promotions or events with which they are affiliated. Many states also extend this prohibition to the athletes’ training teams, family members and others that have access to “inside information” relating to the athletes and their events. In some instances, violations of these prohibitions could result in criminal charges. The UFC’s contracted athletes are not exempt from these prohibitions, which state legislators and regulators have implemented for the purpose of maintaining the integrity of our sport.

In order to assist our athletes in understanding their obligations under the laws of the majority of states in which sports betting is permitted, and in further support of these integrity measures, UFC has incorporated a wagering prohibition into the UFC Athlete Conduct Policy expressly prohibiting athletes from wagering on any UFC match. We have also provided some additional information to assist athletes determining the potential scope of state-imposed wagering restrictions on others.”

Note: This policy does not prohibit UFC athletes from entering into sponsorship agreements with sports betting companies. UFC athletes may continue to pursue such sponsorships in accordance with applicable law.

The new rule also mentions that betting through a third party is prohibited.

The UFC is encouraging athletes to snitch on each other. The new rule states: “An athlete that becomes aware or has knowledge of any wagering in violation of these restrictions must immediately notify UFC of such incident in accordance with this UFC Athlete Conduct Policy.”
