Resorts World Faces Whistleblower Suit Over $13 Million Casino Credit

A former Resorts World Las Vegas compliance director is suing the casino, alleging he was fired after reporting suspicious activity tied to up to $13 million in unpaid casino credit. Preston Banks says the casino retaliated against him; Resorts World denies the allegations.

Banks worked at the Strip resort from September 2022 until his termination on September 29, 2025. Before joining, he spent about 16 years at the U.S. Treasury Department’s Financial Crimes Enforcement Network, according to the lawsuit.

His complaint describes a group that began with patrons mainly from Argentina and allegedly grew to between 60 and 150 people from several countries. Banks says casino records raised concerns including unverified sources of funds, third-party payments on casino credit and coordinated betting. These are allegations, not court findings.

Banks submitted a report to the resort’s chief compliance officer and other staff on September 2, 2025. Nine days later, the casino barred 28 patrons and sent accounts with roughly $12 million to $13 million in unpaid credit to the Clark County district attorney for collection, the complaint says.

Banks says he was fired 27 days after submitting the report. He also alleges that a version later shown to Nevada gaming regulators omitted material details, including a casino executive’s characterization of some activity as “cultural.” Resorts World has not admitted altering the report.

The resort called the lawsuit “frivolous” and said it strongly denies its allegations, according to the Las Vegas Review-Journal. The dispute follows a separate Nevada regulatory case: Resorts World agreed in March 2025 to pay a $10.5 million fine over alleged anti-money-laundering failures involving illegal bookmakers.

Banks seeks reinstatement or future lost wages, damages and legal fees. The federal case, filed September 14, 2026, also claims retaliation under the Anti-Money Laundering Act and wrongful termination under Nevada law. The court has yet to resolve the claims.
