How big is the crypto casino market?
The crypto-casino industry loves big, unverifiable numbers. Here are the ones you can actually check — aggregated from every operator we map on-chain, with wash/treasury volume stripped out. As of the latest refresh: 92 tracked operators, $648.7M in verifiable reserves, and $1.09B of verified 7-day volume across 9 chains.
≥medium-confidence attributed operators only · reserves and volume read live from public blockchains · anomalous wash/treasury volume excluded · refreshed continuously.
How concentrated is the market?
On-chain gambling is top-heavy: the five largest operators by mapped reserves hold roughly 78% of all tracked reserves, and the top ten about 86%. By verified volume the top five account for around 76%. A long tail of smaller operators shares the rest. That concentration matters for players — the biggest brands aren't automatically the safest, but they are the most scrutinised and the easiest to verify on-chain.

Why these numbers are lower than headlines
Most "crypto casino market size" figures are raw throughput — inflated several times over by internal hot-wallet churn, double-counting and treasury/market-making movement. We count only external-facing flow and hold anomalous-volume operators under review, so our numbers are smaller but honest. They're also a floor: reserves and volume we haven't attributed yet aren't included. Pick any operator and verify it on a block explorer.
FAQ
Across the operators Tekel Data maps on-chain, we currently track $648.7M in verifiable reserves and $1.09B of verified (wash-excluded) player volume over the last 7 days, spread across 9 blockchains. This is a floor, not a ceiling — it covers only wallets we've attributed with at least medium confidence, and excludes anomalous wash/treasury volume. Figures update continuously.
Tekel Data currently tracks 92 crypto-casino operators with attributed on-chain activity and at least medium-confidence data. The true number of live brands is larger — many are too small, too new, or too opaque to attribute reliably, and we deliberately exclude those we can't verify rather than pad the count.
Highly concentrated. The five largest operators by mapped reserves hold roughly 78% of all tracked on-chain reserves, and the top ten about 86%. Stake is currently the single largest by mapped reserves. By verified volume the top five account for around 76%. See the live table on this page for the current breakdown.

Methodology & disclaimer. Figures are derived from on-chain transfers attributed to wallets we associate with each operator, plus third-party ratings shown with their source. Blockchain attribution carries inherent uncertainty, and reserves are an all-chain best-effort estimate from mapped wallets — coverage varies by operator.
