Kraken reports 102.9% Bitcoin reserves, with a reference date of June 30

Kraken published proof-of-reserves figures as of June 30, 2026, showing a Bitcoin (BTC) reserve ratio of 102.9%, alongside Ethereum (ETH) at 100.5%, Solana (SOL) at 100.6%, XRP at 102.3%, Cardano (ADA) at 100.3%, and stablecoins USDC and USDT each above 105%. The ratios compare assets included in the review against customer balances at that snapshot date, verified through a third-party accountant. Kraken cautioned that each figure is asset-specific and the 102.9% BTC ratio should not be read as an exchange-wide reserve level or as coverage of all liabilities. The disclosure matters because proof-of-reserves data is a key transparency benchmark for centralized exchanges following past industry collapses. Watch for whether Kraken publishes follow-up attestations covering the full liability side and whether other major exchanges match this per-asset granularity.
