US online gaming deposits surge 18.8% in March 2026, retention slips

US player deposits are climbing while retention signals point in the other direction.

ByCasinoRankr Editorial Team|Updated May 19, 2026

US online gaming average monthly deposits rose 18.8% to $726 in March 2026, according to Optimove's March 2026 US Gaming Pulse Report published April 14, 2026, but active player retention fell to 64% over the same period.

The March data shows a sharp spending rebound after a soft stretch through late 2025 and early 2026. The retention decline signals that operators may need to adjust loyalty programs to keep players engaged. The gap between US and global retention rates widened to 10 percentage points.

Source and methodology

Optimove's report tracks deposit, betting, and retention data across US and global online gaming operators. The Nevada Gaming Control Board separately reported March 2026 win of $1.427 billion from the state's 452 major casinos, up 11.8% year over year.

March rebound driven by sports betting

US average monthly deposits climbed from $611 in February to $726 in March 2026, a month-over-month increase of 18.8%. Average sports betting amounts jumped 27.3% to $937, while average casino betting rose 12.9% to $6,663. Optimove attributes the lift primarily to March Madness, particularly on the sports betting side.

Retention gap widens vs global markets

US active customer retention dropped from 67% in February to 64% in March 2026. Over the same period, the global retention rate rose from 72% to 74%. US players averaged 7.9 activity days in March, compared to 9.4 days for global players. The global average deposit in March was $236, nearly flat from $233 in February.

Nevada land-based win hits $1.427 billion

The Nevada Gaming Control Board reported that the state's 452 major casinos won $1.427 billion in March 2026, up 11.8% year over year. This figure is not directly comparable to online data, as it reflects slot machine and table game win rather than player deposits or retention metrics.

What remains unclear

The Optimove report does not provide operator-level breakdowns of which platforms drove the deposit increases. State-level data for the US-versus-global comparison is also absent. The report does not separately isolate the impact of March Madness on deposits versus sports betting, and sweepstakes casino data is not included.

What happens next

Operators may adjust promotional strategies to address the retention decline, which could produce more competitive loyalty programs for US players. Optimove's next monthly report will indicate whether the March deposit rebound continues or reverses.
