On April 17, 2024, the National Basketball Association permanently banned Toronto Raptors center Jontay Porter for life. The press release was three paragraphs long. The investigation behind it had taken approximately six weeks. The conclusions were the most serious gambling violations in modern American professional sports.
Porter had bet on NBA games. He had shared confidential health and lineup information with professional bettors. He had pulled himself out of two games early to ensure that prop bets on his own statistical performance would cash. He was the first NBA player banned for gambling since the league suspended Jack Molinas in 1954.
The scheme began to unravel publicly on March 20, 2024. Porter started a Toronto Raptors home game against the Sacramento Kings. He played three minutes. He recorded zero points, three rebounds, and one assist. He left the game claiming an eye injury and did not return. Several sportsbooks flagged a suspicious betting pattern within minutes of his exit.

The pattern was the under bets on his statistical totals. Porter prop lines were unusually small that night because he was a low-minutes reserve. The under bets on his points, rebounds, and assists had been hammered just before tip-off. The DraftKings sportsbook in particular saw approximately eighty thousand dollars wagered on Porter under his line of 7.5 points combined with rebounds and assists. The bets cashed when he left after three minutes.
DraftKings reported the pattern to the integrity monitoring firm U.S. Integrity within an hour of the game ending. U.S. Integrity reported it to the NBA league office that same evening. The NBA opened a formal investigation on March 22, 2024. The investigation interviewed Porter, his agent, his immediate family, and approximately fifteen other people connected to the bets. The investigation found evidence that the March 20 game was the second time Porter had executed the scheme.
The first instance had occurred on January 26, 2024. Porter started a game against the Los Angeles Clippers. He played four minutes. He recorded zero points, two rebounds, and one assist. He left claiming illness and did not return. Approximately sixty thousand dollars in coordinated under bets on his statistical line cashed when he left. The pattern matched the March 20 game with near identical structure.
The investigation also found that Porter had personally placed at least thirteen bets on NBA games using an associate identifier between January and March 2024. The bets totaled approximately fifty-four thousand dollars in stakes. The bets included three parlays that contained the Raptors as one of the legs. NBA rules prohibit any player from betting on any NBA game under any circumstance. The personal betting alone was sufficient grounds for the lifetime ban.
The financial motive for the scheme was simple. Porter was on a two-way contract with the Raptors that paid approximately five hundred thousand dollars per year. He had reported to the investigation that he owed approximately one million dollars in personal gambling debts to several illegal offshore sportsbooks. The under-bet scheme was designed to generate cash quickly to repay the debts. The scheme generated approximately eight hundred thousand dollars in coordinated winnings before it was detected.
Federal prosecutors in the Eastern District of New York opened a criminal case in late April 2024. Porter was charged with one count of conspiracy to commit wire fraud. He pleaded guilty in July 2024. He was sentenced in February 2025 to six months of federal prison followed by three years of supervised release. Four co-conspirators who had placed the coordinated bets were also charged. Three pleaded guilty. The fourth was tried and convicted in late 2024.
The Porter case fundamentally changed how American professional sports leagues approach prop bet integrity. The NBA, NFL, NHL, and MLB collectively imposed new restrictions on prop bets involving low-minutes reserves and players on two-way contracts. Several state regulators, including the New Jersey and Pennsylvania gaming commissions, banned single-player prop bets on bench reserves entirely. The case is now taught in every major sports law program in the United States as the defining example of how legalized sports betting creates new categories of integrity risk that did not previously exist.
