A $10.6 Billion Industry Built on a Free Entry Requirement
Available in US
When I started tracking sweepstakes compliance in this space, the industry was a footnote in gaming industry reports — a niche category that analysts lumped in with social casino apps and free-to-play mobile games. That’s no longer true. The scale of what’s happened in the past four years is genuinely remarkable, and understanding it changes how you think about AMOE as a mechanism. The free entry requirement isn’t a compliance quirk on a small platform. It’s a structural feature of an industry that moved more money in 2024 than many people realize. The sweepstakes gaming sector surpassed regulated iGaming in both reach and revenue in 2024 — a milestone that would have seemed implausible as recently as 2021.
Gross Purchases, Net Revenue, and What the Numbers Mean
The headline number is $10.6 billion in gross purchases for 2024. That’s the total value of Gold Coin packages sold across the sweepstakes casino industry — the primary revenue mechanism for operators who legally cannot sell gambling services. To put that in context: regulated iGaming in the United States — actual licensed online gambling operating exclusively in seven states — generated $8.41 billion in revenue in 2024. The sweepstakes model, technically not gambling and not requiring any state licensing, outpaced the licensed industry in gross revenue terms.
Gross purchases and net gaming revenue are different figures. After paying out prizes and operational costs, the industry’s net revenue in 2024 was approximately $3.4 billion. That’s still a substantial figure, and one that KPMG projected to exceed $4.6 billion on a conservative basis in 2025, with an upper-range projection above $14.3 billion in gross terms. The gap between gross and net reflects how much operators return to players as prize payouts — a relevant figure for anyone thinking about the real return on AMOE participation.
These aren’t speculative estimates from industry insiders with an interest in boosting the numbers. They come from the Eilers and Krejcik Gaming Social Sweepstakes Gaming Monitor and from KPMG’s formal primer on sweepstakes gaming — two of the most authoritative data sources tracking this sector. The commercial gaming industry as a whole recorded $78.61 billion in gross revenue in 2025 according to the American Gaming Association, and the sweepstakes sector was capturing a meaningful share of the same consumer attention.
60-70% CAGR: What Drove the Fastest Growth in U.S. Gaming
A 60 to 70% compound annual growth rate between 2020 and 2024 is extraordinary by any industry standard. For context: the fastest-growing technology sectors typically see 20 to 40% CAGR over sustained periods. Healthcare technology, SaaS platforms, and high-growth consumer apps rarely sustain 60% annualized growth for four consecutive years. The sweepstakes casino sector did.
What drove it? A few converging factors. First, the COVID period accelerated adoption of online entertainment broadly — players who had never used any online gaming platform discovered both regulated and unregulated options simultaneously. Second, sweepstakes casinos had no state-by-state licensing barrier to national expansion. A licensed online casino can only serve players in the handful of states where real-money gambling is legal; a sweepstakes platform could serve players in most of the country from day one. Third, the marketing model relied heavily on digital advertising — and specifically on the “free” angle of AMOE as an acquisition hook.
The Gaming Innovation Group pegged a slightly more conservative growth estimate at 31% CAGR for the sweepstakes platform sector, projecting revenue growth from $3.1 billion in 2022 to between $6.9 and $11 billion in 2025. Even the lower end of this range represents extraordinary sector expansion. The discrepancy between GiG’s 31% estimate and KPMG’s 60-70% figure reflects different methodological choices about which revenue streams to include and how to account for the dual-currency accounting structure.
From Niche to Mainstream: 186+ Platforms in 2024
In 2021, the number of active, verified sweepstakes casino platforms operating in the U.S. could be counted on two hands. By 2024, that count reached 186 and growing — a 340% increase in the number of platforms over three years. This explosion in operator count reflects both the low barrier to entry (no state licensing required) and the demonstrated profitability of the model at scale.
Not all of these 186+ platforms are equally serious compliance participants. Some are well-capitalized operators with dedicated legal teams, verified AMOE programs, functioning player support, and transparent terms. Others are smaller operations where the compliance infrastructure is thinner. The rapid growth in platform count is part of why the regulatory scrutiny that arrived in 2025 was so consequential — when enforcement actions began, they were aimed at a large and varied industry rather than a handful of established players.
For players, the sheer number of platforms creates both opportunity and risk. More platforms means more AMOE addresses to submit to, more daily login bonuses to collect, more potential SC streams. It also means more variation in compliance quality and more platforms where the AMOE program may be nominal rather than genuine. The growth in platform count correlates with the growth in compliance problems — by early 2026, over 100 class-action lawsuits had been filed against sweepstakes operators, a figure that reflects the industry’s rapid scaling outpacing its compliance maturation.
Sweepstakes vs. Regulated iGaming: Revenue Comparison
The comparison between sweepstakes casino revenue and regulated iGaming revenue is one of the most politically charged data points in the gaming policy debate. Regulated iGaming operators pay licensing fees, corporate taxes, and are subject to consumer protection mandates. Sweepstakes operators do not — at least not under the current model. The result is a significant structural cost advantage for sweepstakes platforms that allowed them to grow faster and reach more players than their licensed counterparts.
In 2024, regulated iGaming generated $8.41 billion in revenue across seven states. Sweepstakes platforms generated $10.6 billion in gross purchases across most of the country while paying no gaming taxes. One analyst estimate suggested that sweepstakes casinos captured the equivalent of roughly 13% of the total commercial gaming industry’s revenue — while operating entirely outside the regulatory framework that governs that industry. That disparity is the central argument made by legislators and licensed operators who supported the 2025 state-level restrictions.
For compliance analysts like me, the market size data is context for a simpler observation: the legal mechanism that keeps this entire industry operational is the no-purchase-necessary requirement and the AMOE that fulfills it. A $10.6 billion industry rests on the credibility of a free entry process that most players give very little thought to. That’s a remarkable dependency — and it’s why the quality and integrity of AMOE programs is more consequential than their modest per-request SC amounts suggest.

Industry Size and Stats: Questions Answered
Which sweepstakes casinos generate the most revenue in 2025?
Revenue data at the individual operator level is not publicly disclosed, and the sweepstakes sector doesn’t have the same reporting requirements as publicly traded gambling companies. Industry estimates indicate that a small number of large operators account for the majority of gross purchases — the pattern common to most consumer platform markets. The operators that tend to appear most frequently in market discussions are those that have been operating longest, have the largest player bases, and have the most established brand recognition. That said, I don’t maintain or publish operator rankings, which would require independently verified financial data I don’t have access to.
How did sweepstakes casinos surpass regulated iGaming revenue in 2024?
The revenue crossover reflects the structural advantage sweepstakes platforms had over licensed operators: national reach without state-by-state licensing. Regulated iGaming was confined to seven states with active markets in 2024. Sweepstakes platforms served players in most of the country. The math on total addressable market gave sweepstakes operators a substantial head start in player volume, and the Gold Coin purchase model proved effective at converting engaged players into paying customers even at relatively low per-transaction amounts. The 60-70% CAGR documented by KPMG between 2020 and 2024 reflects how quickly that structural advantage compounded.
