Welcome back to The Weekly Peep — Peeped's read on where the money is moving in crypto casino and iGaming markets. This edition: stablecoins now do most of the talking in on-chain deposit data, the US sweepstakes crackdown keeps adding states, and the mainstream gambling world's M&A wave is a reminder of how differently the two markets are consolidating.
The number that matters: stablecoins now dominate crypto casino deposits
The clearest structural shift in the data this year isn't a new operator or a new market — it's the asset players are actually funding with. Industry trackers now put stablecoins at roughly 60% of on-chain crypto casino deposit volume, with USDT and USDC together accounting for the large majority of that share; a market report covering Q2 2026 put Tether and USDC combined near 75% of tracked deposit volume for the quarter. That's a reversal from the early years of crypto casino, when Bitcoin's price swings were part of the appeal for some players and a deterrent for others. Stablecoins remove the swing: a $100 deposit is worth $100 at withdrawal, which is exactly the property that lets an operator's own reported GGR and an outside tracker's on-chain deposit figure start to line up. It also lowers the bar for players coming from fiat-first sweepstakes sites, which matters given where those players are being pushed next.
Sweepstakes crackdown: the state count keeps climbing
The sweepstakes-casino wind-down we've been tracking all year hasn't slowed. Eleven states have now passed explicit statutory bans on the dual-currency sweepstakes model since 2025 — California, Connecticut, Indiana, Louisiana, Maine, Montana, Nevada, New Jersey, New York, Oklahoma and Tennessee — with New York's law notable for reaching past the operators themselves to the payment processors, geolocation vendors and platform providers that support them. Iowa took the enforcement route instead, handing regulators new cease-and-desist power over unlicensed operators rather than an outright ban. The pattern from earlier editions holds: every state that closes the sweepstakes loophole is one more pool of US players with a gambling habit and nowhere fiat-licensed to put it, which is the overflow that shows up as inbound volume on offshore crypto casino books rather than in the eight states with regulated iGaming.
Market structure: concentration hasn't moved, and the mainstream side is consolidating differently
The last published deposit-volume read still has the market at roughly $44.7 billion tracked, up 84% year on year, with the top three operators — Stake, Rainbet and Shuffle by most trackers' count, Roobet close behind — holding around three-quarters of it. A refreshed Q3 figure is expected in October. Worth noting for contrast: the regulated land-based and iGaming side of the industry is consolidating through mega-deals instead — Fertitta Entertainment's roughly $17.6 billion deal to take Caesars Entertainment private, and Flutter Entertainment (FanDuel's parent) moving to buy a European B2B platform provider to shore up its tech stack ahead of new US state launches. Crypto casino concentration, by contrast, isn't consolidating through acquisitions at all — it's a handful of operators simply outgrowing the rest of the field organically, which is a different kind of story for on-chain data to keep proving out.
What we're watching next
- Whether the stablecoin share keeps climbing, or Bitcoin/altcoin deposits stabilize once the current run-up settles.
- Whether any additional states move on sweepstakes bans before year-end legislative sessions close.
- The Q3 deposit-volume update expected in October — the first real test of whether the top three's share moves.
