A crypto casino has the same problem as any casino: the money has to get to the table. It cannot mint its own chips. Somewhere upstream, a player has to turn dollars or Bitcoin into a balance the house will accept, and on the Ethereum blockchain that conversion almost always runs through a big exchange first.
Over the year from July 2025 through June 2026, $1.56 billion moved directly from the on-chain wallets of ten major exchanges into the deposit addresses of eight crypto casinos. We can be precise about that figure because we measured it against the casinos' full address sets, every wallet, not a sample. And it counts only the cleanest path: a single transfer from an exchange's own withdrawal wallet to a casino's front door, with nothing in between. Money that takes a longer route, through a player's personal wallet first, is on top of it.
One exchange dominates the flow to a degree that is rare in any market. Binance sent $998 million of the $1.56 billion, close to two-thirds of everything, and more than triple the next two exchanges put together.
One pipe carries most of it
Behind Binance the field falls away fast. Coinbase is a distant second at $161 million, then Bybit ($140M), OKX ($120M) and a long tail down to Gemini's $1.8 million. But the concentration is sharper still when you see where the money goes, because it barely spreads out at all.
A single channel, Binance's wallets to Stake's deposit addresses, carried $874 million over the year. That one exchange-to-casino relationship is more than half of all $1.56 billion measured. Stake, the site a Bitquery census earlier this year found holds 78 percent of on-chain gamblers, took $1.26 billion in total, roughly four of every five dollars in the entire dataset. Nearly every exchange we traced routes its gambling flow to the same address.
The offshore names carry it
Three of the ten exchanges answer to US regulators: Coinbase, Kraken and Gemini. Together their customers moved $197 million to the casinos over the year, against $1.36 billion from the seven offshore venues. The gap is Binance. Where the earlier, cruder version of this measurement made the US share look larger, the full data is blunt: the money running into these casinos is overwhelmingly offshore money, and few of the casinos on the receiving end hold a US gambling license.
We report that as a measurement and stop there. What an exchange should do about where its customers send money once it leaves the building is a question for regulators. The blockchain only shows that the money went.
The longer road adds more
The $1.56 billion is the direct hop. Most gamblers do not wire funds from an exchange straight to a casino; they pull the money to their own wallet and fund the casino from there. We estimated that path too, matching each wallet month by month against what it took in from an exchange and what it then paid to a casino, and crediting only the smaller of the two so the estimate cannot run ahead of the money. By that cautious method, another $706 million or so flowed in through player wallets. Unlike the direct figure, this one leans on address sampling and is an estimate, not a measurement, so we keep it separate and do not stack the two into one headline.
To the exchange, it barely registers
Then there is the number that keeps all of this in proportion. Weigh the casino money against everything these exchanges push out onto the chain, and it nearly disappears.
The casino-bound share of each exchange's on-chain outflow runs from about 0.01 percent to 0.22 percent. Binance moved more than $200 billion out of its Ethereum wallets in a single three-month stretch; the slice that reached a casino is under a tenth of one percent of it. To the exchange, the flow is a rounding error it would never feel. To the casino catching it, the same stream is a primary source of funding. On-chain, you can stand at both ends of the pipe and read both numbers off the same transactions.
The money travels one way
We looked for the return trip, the winnings and cashed-out balances heading back from casino payout wallets to exchange accounts. On the direct path it is faint: about $6 million over the year, against $1.56 billion going the other way. That $6 million is itself an undercount, because casinos usually pay a player's personal wallet rather than an exchange, and because we can only see a slice of each exchange's deposit addresses. Even so, the shape is clear. Between exchanges and casinos on Ethereum, the measurable money runs almost entirely one way: in.
The eight casinos we followed turn out to be essentially the whole board. Set their inflow against every labeled gambling address on Ethereum, more than 850,000 of them, and the eight capture close to 100 percent of the exchange money. The rest of the field receives almost nothing. On-chain, these eight sites are very nearly the entire gambling market.
How we did this
Every number here comes from Ethereum transfer data indexed by Bitquery, computed one calendar month at a time from July 2025 through June 2026 and priced at that month's on-chain ether rate, with stablecoins counted at a dollar and only real USDC, USDT and DAI treated as dollars. Exchange withdrawal wallets are not labeled in full anywhere, so we reconstructed them from deposit-sweep behaviour for Binance, Coinbase, Gemini, OKX, Bybit, Bitget and MEXC, each clearing a test that its wallets capture essentially all of the exchange's outbound volume; for Kraken, HTX and KuCoin the reconstruction fell short, so we used labeled wallets and treated their totals as floors.
The direct figure is a measurement: single-hop transfers from those wallets to the complete deposit-address set of all eight casinos, with no sampling and no scaling. The routed figure is an estimate, matching per wallet per month the smaller of exchange-in and casino-out, and it does rely on address samples, which is why we keep it apart. This is an Ethereum-only view. Deposits on other chains, in fiat, or off the chain do not appear, and because one person can hold many wallets, the counts are of wallets, not people. Labels are a July-2026 snapshot; the three most recent months are shaded on the charts, because exchange wallets rotate and our reconstruction thins out near the present.
One limitation frames everything above: this analysis is only as complete as the labels behind it. Exchange withdrawal wallets and casino deposit addresses are not published anywhere in full, so every figure rests on the label set Bitquery had indexed as of July 2026. An address we have not yet attributed to an exchange or a casino is invisible to the measurement, which is why the direct total is a floor rather than a ceiling — the true flow can only be equal to or larger than what the labels let us see. As Bitquery's labelling deepens, these numbers will move up, not down.
