Nobody agrees on how big the crypto casino industry actually is. One widely cited estimate puts 2024 revenue at $81.4 billion. Another puts it at roughly $10 billion. That is an eightfold gap on the same market.
Blockchain data analytics firm Yield Sec produced the larger number for a 2025 Financial Times report. Crypto analytics site Tanzanite pushed back hard, arguing the real figure sits closer to $10 to $11 billion.
Gambling Insider ran its own blockchain analysis to test both claims. The findings line up much closer to Tanzanite’s number than to Yield Sec’s.

Two Numbers, One Market
The table below lines up all three figures side by side.
| Source | Headline Figure | Year | Method |
| Yield Sec | $81.4 billion | 2024 | Web traffic and spending assumptions |
| Tanzanite | $10-11 billion | 2024 | Wallet tracking across 4 networks |
| This analysis | $5.7-11.4 billion | 2025 | Wallet tracking across 3 networks |

Gross gaming revenue, or GGR, measures the difference between what a casino takes in bets and pays out in winnings. It is the standard yardstick for the size of any gambling market.
Tracking Money on the Blockchain
Every crypto payment sits on a public blockchain that anyone can inspect. The catch is that wallet addresses do not carry names, so tying a wallet to a specific casino takes real detective work.
Casinos typically give each customer a personal deposit address, then periodically sweep those balances into a small number of central hot wallets. Counting money that arrives at the hot wallets captures nearly all customer deposits.
Researchers identified 29 labeled hot wallets across 12 casinos, seven major brands, and five smaller sites, using public tags from Etherscan and Arkham Intelligence. They then pulled deposit totals from Ethereum, BNB Chain, and Tron using the free blockchain query tool Dune.
What the Data Showed
The 12 tracked casinos received $22.7 billion in deposits across 2025 on the three networks studied. One casino dominated the field.
| Casino | 2025 Deposits Tracked | Share of Total |
| Stake | $15.2 billion | About 67% |
| Roobet | $4.2 billion | About 18% |
| 5 tail casinos combined | $151 million | Under 1% |
| Remaining majors (Rollbit, BC.Game, Gamdom, Duelbits, Shuffle) | Remainder of $22.7 billion total | About 14% |

Stake alone brought in $15.2 billion, split between Ethereum and Tron. Its Tron deposits alone more than doubled over the year, climbing from $542 million in July to $1.14 billion in December.
The five smaller “tail” casinos combined for just $151 million, less than 1% of Stake’s total. That result challenges the idea that thousands of small operators add up to a massive hidden market.
Turning Deposits into Revenue
Deposits are not the same as revenue. The industry convention converts deposits to GGR using a ratio of roughly 37 cents earned per dollar deposited, based on Stake’s own reported numbers.
Applying a range of 25 to 50 cents per dollar to the $22.7 billion in tracked deposits produces a GGR estimate between $5.7 billion and $11.4 billion for 2025, in line with Tanzanite’s figure and far below Yield Sec’s.
Why the Estimate Still Has Blind Spots
The analysis cannot see Bitcoin or Litecoin deposits, since those older blockchains do not use the same reusable wallet structure. Solana coverage is also incomplete, and payments routed through outside processors never touch a labeled wallet.
Wallet labels also change over time as casinos rotate accounts, so even the tracked figures likely understate real activity. Every published crypto gambling estimate, including this one, depends on a wallet list nobody can fully verify.
Yield Sec Defends the $81.4 Billion Figure
Yield Sec founder Ismail Vali told Gambling Insider the gap comes down to definition, not bad math. Yield Sec counts any gambling-style product that markets itself using the word “crypto,” including sports betting, prediction markets, and financial products it considers disguised gambling.
Under that broader definition, Yield Sec allocates only 59% of its $81.4 billion total, about $48 billion, to crypto casinos specifically. Vali said he stands behind the original research: “We did that work for the FT… and we stand by it.”
Vali also argued that some operators report only part of their activity on-chain, which would make blockchain-only tracking undercount the true market.
What This Means for US Players
Almost every casino named in this investigation, including Stake, Roobet, and BC.Game, operates offshore under licenses from jurisdictions such as Curaçao, Anjouan, or the Isle of Man. None hold a US state gaming license.
That matters more than market size. Unlicensed offshore crypto casinos fall outside US consumer protections, meaning no state regulator to handle disputes, no guaranteed payout enforcement, and no standard responsible gambling safeguards.
Players in the US looking for real-money casino games should stick to sites licensed in their home state. A crypto casino’s size or popularity says nothing about whether it can legally serve US players or protect their funds.
FAQs
How big is the crypto casino industry?
Estimates range from about $10 billion to $81.4 billion in 2024 gross gaming revenue, depending on methodology. A 2026 blockchain analysis by Gambling Insider found deposits consistent with a GGR range of $5.7 billion to $11.4 billion, closer to the lower estimate.
Why do crypto casino revenue estimates vary so much?
The two headline figures use different definitions and methods. Yield Sec's $81.4 billion estimate covers a broad range of crypto-labeled gambling products using web traffic modeling. Tanzanite's $10 to $11 billion estimate tracks actual blockchain deposits to known casino wallets, a narrower and more verifiable scope.
Are crypto casinos like Stake legal for US players?
No major crypto casino covered in this analysis holds a license to operate in any US state. Sites like Stake, Roobet, and BC.Game run under offshore licenses, so US players using them have no state-level consumer protection or dispute resolution.
