Ethereum exchange holdings are reported at 6.06 million ETH, down 73% from the June 2020 peak of 22.9 million ETH. An earlier estimate put exchange-held supply at about 14.88 million ETH after roughly 6.4 million ETH left exchanges since July 2025, indicating a discrepancy between reported data sets or measurement periods. The decline has coincided with ETH moving into staking, ETFs, treasury strategies and long-term custody; the earlier estimate also showed ETH exchange supply below 12.7%, versus 16.5% for BTC, with BTC holdings relatively stable, according to Lisk business development lead Leon Waidmann.
