Binance’s May 2026 Proof-of-Reserves Report Shows 100.22% Bitcoin Backing

What the report says about major assets

The strongest May-specific data point in the cited reporting is Bitcoin. Binance’s official proof-of-reserves pages state the broader objective: users should be able to verify that account balances are fully backed 1:1 by assets Binance holds in custody.^[1][6] However, the available May-specific coverage does not give precise May 2026 reserve ratios or balances for ETH, USDT, BNB, SOL, FDUSD or other major assets.

The nearest detailed context in the cited sources is the April 2026 proof-of-reserves reporting, which listed BTC, USDT, ETH, BNB, SOL, FDUSD and many other tokens, and reported the following ratios for several major assets: BTC 100.03%, USDT 105.62%, ETH 100.00%, and BNB 100.96%.^[17][18] Those figures help show how Binance has recently presented major-asset coverage, but they should not be substituted for the missing May 2026 table.

How to read Binance’s proof-of-reserves claim

Binance defines proof of reserves as evidence that the assets it holds in custody for users cover those user assets 1:1, plus reserves.^[1][6] That is narrower than a full corporate audit. A PoR update can help users assess whether a named asset appears backed in the report, but it does not necessarily answer broader questions about all liabilities or the exchange’s full financial condition.^[2]

Bottom line

For Bitcoin, Binance’s May 2026 proof-of-reserves report is positive but modest: the reported BTC reserve ratio was 100.22%, just above full backing.^[2] For other major assets, the safest reading is more cautious: Binance’s PoR framework says user assets should be backed 1:1, and recent April reporting showed several major assets at or above 100%, but the available May-specific evidence does not verify exact ETH, USDT, BNB, SOL or FDUSD reserve ratios.^{[1][6][17][18]}
