Yes, insider betting is illegal. There is no single federal statute that uses the phrase, but prosecutors charge the conduct under wire fraud, sports bribery, the Wire Act, the Illegal Gambling Business Act, and in organized cases RICO, with federal exposure reaching 20 years in prison. Every state that has legalized sports betting also bars athletes, coaches, officials, and people close to them from wagering on events they can influence, and the major leagues impose their own bans on top of anything a court does.
What Insider Betting Is
Insider betting means using non-public information to place wagers or to help someone else place them. The information has to be the kind that would move odds or change outcomes if the public knew it: an undisclosed injury, a referee assignment, a horse’s lameness before scratches are posted. That informational edge is what separates insider betting from ordinary gambling.
The conduct takes a few recognizable forms. An athlete tips a friend about a teammate’s concussion. A trainer in horse racing passes word about a horse that won’t run. A referee leaks officiating assignments. At the far end, the insider manipulates the event itself, pulling out of a game early or underperforming so co-conspirators can win prop bets.
Who Counts as an Insider
An insider is anyone with access to non-public information that could affect the outcome or odds of an event. Athletes, coaches, trainers, referees, and league officials are the obvious ones. In horse racing the category extends to jockeys, stable hands, and veterinarians. It also reaches people readers don’t always expect: team physicians, equipment managers, statisticians with access to injury data, and immediate family members who receive and act on confidential information.
The person placing the bet does not have to be the insider. Someone who receives a tip and wagers on it has the same legal exposure, and prosecutors routinely charge both the source and the bettor.
The Federal Charges Prosecutors Use
Because no single federal statute defines insider betting, charges are built from several overlapping laws. Which ones apply depends on the conduct, the dollar amounts, and whether the scheme crossed state lines.
Wire Fraud
Wire fraud is the workhorse. It covers anyone who uses electronic communications (phone, internet, text) to carry out a scheme to defraud when the communication crosses state lines. The penalty is a fine, up to 20 years in prison, or both.1Office of the Law Revision Counsel. 18 U.S.C. 1343 – Fraud by Wire, Radio, or Television Because almost every modern sports bet is placed online or by phone, this statute reaches the vast majority of insider betting schemes.
Sports Bribery
When insider betting crosses into game manipulation, the federal sports bribery statute applies. It targets anyone who uses bribery to influence the outcome of a sporting contest, professional or amateur, when the scheme involves interstate or foreign communications. Maximum penalty: five years, a fine, or both.2GovInfo. 18 U.S.C. 224 – Bribery in Sporting Contests A bettor who simply wagers on a tip may face wire fraud; an insider who takes money to alter a game picks up bribery on top. Prosecutors often stack both.
The Wire Act
The Wire Act reaches people in the business of betting who use wire communications to transmit bets, wagers, or information assisting the placement of bets on sporting events across state lines. The maximum is two years, a fine, or both.3Office of the Law Revision Counsel. 18 U.S.C. 1084 – Transmission of Wagering Information The lower ceiling makes it less dramatic, but it is tailored to gambling and reaches intermediaries who transmit wagering information even when they are not placing the bets themselves.
Illegal Gambling Business Act
When insider betting operates as part of a larger ring, the Illegal Gambling Business Act applies. It covers gambling operations that violate state law, involve five or more people, and have been running for more than 30 days or gross at least $2,000 in a single day. Conviction carries up to five years.4Office of the Law Revision Counsel. 18 U.S.C. 1955 – Prohibition of Illegal Gambling Businesses
RICO
An insider betting operation involving an organized group committing repeated offenses can be charged under the Racketeer Influenced and Corrupt Organizations Act. RICO requires proof that the defendants operated as an enterprise and committed at least two qualifying crimes within ten years. Gambling, wire fraud, and money laundering all qualify.
The penalties are heavy. A conviction carries up to 20 years, or life if one of the underlying offenses carries a life sentence. Fines can reach twice the gross profits of the activity, and criminal forfeiture of property acquired through or used to support the enterprise is mandatory.5Office of the Law Revision Counsel. 18 U.S.C. 1963 – Criminal Penalties RICO is relatively rare in insider betting cases because the enterprise and pattern elements are hard to prove, but when the evidence supports it, it gives prosecutors enormous leverage.
State Laws and League Discipline
Roughly 40 states plus the District of Columbia have legalized some form of sports betting, and nearly all of them have built insider betting prohibitions into their regulatory frameworks. The specifics vary, but the common rule is that athletes, coaches, officials, team employees, and their immediate family members cannot bet on events they participate in or have inside knowledge about. Violations carry criminal penalties under state gambling statutes, and regulators can revoke licenses and permanently exclude offenders from casinos and sportsbooks.
Professional leagues operate on a separate track, and they tend to move faster than prosecutors. The NBA banned Jontay Porter for life in 2024 after an internal investigation found he had disclosed confidential information to bettors and wagered on his own team’s games. More than two dozen NBA players have received lifetime bans in league history, with gambling among the most common reasons. The NFL, MLB, and NHL all maintain policies allowing indefinite suspension or permanent banishment, and none of it requires a criminal conviction. Leagues act on their own investigations under their own conduct rules.
Fines, Forfeiture, and Money Laundering Exposure
Prison is only part of the picture. Money laundering charges, which often ride along with larger insider betting schemes, carry fines of up to $500,000 or twice the value of the property involved, whichever is greater.6Office of the Law Revision Counsel. 18 U.S.C. 1956 – Laundering of Monetary Instruments
Federal law also allows the government to seize property connected to insider betting. Civil forfeiture reaches any property involved in or traceable to money laundering transactions linked to the underlying crime.7Office of the Law Revision Counsel. 18 U.S.C. 981 – Civil Forfeiture That means not just the winnings themselves but bank accounts, vehicles, or real estate bought with them. In RICO cases, criminal forfeiture is mandatory, and if the original property has been hidden or spent, the court can seize substitute assets of equivalent value.5Office of the Law Revision Counsel. 18 U.S.C. 1963 – Criminal Penalties
Using a Proxy Does Not Help
Some insiders try to avoid detection by having a third party, known in gambling circles as a beard, place bets on their behalf. The insider supplies the tip or the money, and the proxy walks into the sportsbook or logs into the app. Both participants are liable. The insider remains on the hook for the underlying fraud, and the proxy picks up charges for aiding the scheme. If the bets cross state lines, the Wire Act adds federal exposure for everyone involved.3Office of the Law Revision Counsel. 18 U.S.C. 1084 – Transmission of Wagering Information Sportsbook operators that fail to catch proxy activity face their own fines and license actions.
How It Gets Caught
Two systems do most of the detection work. Third-party integrity monitors analyze betting data in real time against a baseline of normal activity and flag anomalies that line up with events like unannounced injuries or roster changes.8IC360. What Is Integrity Monitoring? A sudden line move on an obscure prop bet right before a lineup change is exactly the signal that opens an investigation.
The second system is financial. Under the Bank Secrecy Act, casinos and sportsbooks must file a Suspicious Activity Report with FinCEN for any transaction of $5,000 or more that appears tied to illegal activity, is structured to evade reporting, or lacks any obvious lawful purpose.9eCFR. 31 CFR Part 1021 – Rules for Casinos and Card Clubs The reports are confidential; the operator cannot tell the bettor one was filed.10Financial Crimes Enforcement Network. Interpretation of Suspicious Activity Reporting Requirements Together, the two systems make sustained insider betting hard to hide.
How the Tracks Converge: The Jontay Porter Case
Porter, then with the Toronto Raptors, disclosed confidential team information to sports bettors and agreed to withdraw early from games so his associates could win bets on his statistical performance. He also placed bets himself, including wagers against his own team. He later said he did it to escape large gambling debts.
The NBA moved first and banned him for life. Federal prosecutors in Brooklyn then charged him with conspiracy to commit wire fraud, a felony carrying up to 20 years.1Office of the Law Revision Counsel. 18 U.S.C. 1343 – Fraud by Wire, Radio, or Television He pleaded guilty in July 2024. The case shows how league discipline, federal fraud charges, and the financial surveillance that feeds investigations can land on a single person at once.
