Binance Holds $130B in Reserves, Coinbase Next at $88B

Binance holds $130.1 billion in digital assets across its public wallets, the largest on-chain reserve of any exchange. Coinbase follows with $87.96 billion. OKX holds $23.21 billion, Upbit $19.12 billion, Robinhood $18.6 billion, Bitfinex $18.59 billion, Kraken $16.11 billion, and Bybit $13.99 billion. The figures come from Arkham Intelligence, which tracks blockchain wallet data.

The snapshot covers customer-held assets visible on public wallets. It excludes fiat balances, exchange-native tokens in separate addresses, and assets held off-chain with custodians. Liabilities – what each exchange owes its users – are absent, so the data cannot confirm solvency. What it does provide is a ranking of which platforms hold the deepest on-chain liquidity.

On-chain reserve data became a standard transparency metric after FTX collapsed in 2022, wiping out an estimated $8 billion in customer funds. Many exchanges now publish wallet addresses and commission third-party audits. Arkham's report offers a cross-platform view at a single point in time, letting users compare sizes directly.

The combined reserves of the eight exchanges sit at roughly $327.7 billion. Binance alone accounts for nearly 40% of that sum. Coinbase adds another 27%. The concentration matters for anyone choosing where to trade. A platform with $130 billion in reserves can absorb large withdrawals more easily than one with $14 billion. Reserves alone do not measure default risk. Legal and regulatory exposure can trigger runs that drain any wallet.

Binance's reserve lead comes with a history of enforcement actions. The DOJ's ongoing supervision of the exchange, detailed in a recent report, adds counterparty risk that numbers do not capture. Coinbase, as a publicly listed U.S. company, faces different regulatory constraints and reporting obligations. Upbit's $19 billion reserve is tied largely to South Korean retail flows, which carry their own liquidity dynamics.

Reserve figures shift constantly with deposits and withdrawals. A single large outflow can rearrange the rankings within hours. The real test of reserve transparency comes during market stress – when prices slide and withdrawal queues form, on-chain data lags. FTX's reported reserves looked healthy ahead of its collapse. The lesson, repeated by industry analysts since, is that reserves are a starting point, not a guarantee.

Arkham's ranking offers a current snapshot of where the industry's assets sit. Binance leads by a wide margin. The gap could narrow quickly if legal uncertainty drives users to diversify. For now, the eight exchanges listed hold more than $327 billion across public wallets. That figure will change with the next deposit wave or the next crash.
