Four hundred and fifty-seven billion, on chain

On-chain potentially taxable crypto activity reached more than 457 billion dollars worldwide in 2025, according to a Chainalysis report published this week. The United States alone accounts for roughly 112.6 billion of that.

The measure combines realised gains attributed to both centralised and decentralised exchanges, income from mining, staking, lending and gambling, and payments denominated in crypto. By region, North America leads at 134.6 billion dollars, followed by the European Union at 125.1 billion and East Asia at 54.7 billion.

The methodology is stated rather than implied, which is the reason to take the number seriously. Activity is measured across six chains — Bitcoin, Ethereum, Solana, Tron, BNB Smart Chain and Base — and attributed to countries using a combination of direct location signals and proportional allocation based on service-level activity.

The firm is also explicit about what the figure misses, and the admission is the most useful part of the report. Trading, staking and lending conducted inside centralised exchanges do not appear on chain at all, so the estimate understates total economic income rather than overstating it.

The policy argument follows from the gap. The OECD's Crypto-Asset Reporting Framework, the European Union's DAC 8 and domestic information reporting reforms are described as meaningful steps, but material portions of decentralised finance, peer-to-peer transfers, private wallet holdings and historic activity fall outside their scope entirely.

For a tax authority the practical consequence is uncomfortable. A reporting regime that captures the exchange-intermediated part of a market and none of the rest does not produce a smaller picture of the same shape — it produces a picture biased towards the participants who were already easiest to see.
