Illegal iGaming operators in the U.S. reached $97.4 billion in GGR in 2025, according to Gaming Compliance International

Gaming Compliance International says illegal iGaming operators in the United States generated $97.4 billion in GGR in 2025. For PSPs, acquirers, and banks that touch gambling traffic, that number is the part that matters: it is the size of the addressable volume moving outside licensed rails.

1. The figure comes from Gaming Compliance International’s research and is framed as GGR (gross gaming revenue), the standard measure of operator revenue in gambling.
2. The source identifies the activity as illegal iGaming operators in the U.S., which makes the payment angle straightforward: the volume exists, but it sits in a segment that licensed processors and partner banks usually treat as higher-risk or restricted.
3. For PSPs and acquirers, the practical takeaway is that U.S. iGaming traffic remains large enough to be a meaningful business line, even when it is not eligible for mainstream underwriting or card-network comfort.
