Binance Users Add Nearly 26000 Bitcoin In One Month

Binance users accumulated nearly 26,000 $BTC in a single month, according to the exchange's latest Proof of Reserves report. User Bitcoin balances rose by 25,838 BTC between May 1 and June 1, climbing to roughly 630,000 BTC in total.

The data points to continued accumulation on the world's largest crypto exchange by trading volume, even as broader market conditions turned choppy. Binance operates under a $4.3 billion settlement with the US Department of Justice and now publishes quarterly Proof of Reserves attestations.

What Proof of Reserves Shows

Binance's May 2026 Proof of Reserves update reported a BTC reserve ratio of 100.22%, indicating the exchange holds slightly more Bitcoin than the total amount owed to its users. The report covers assets held in custody for users, providing evidence that Binance holds funds to cover all user assets on a 1:1 basis, with some additional reserves.

Binance publishes its Proof of Reserves report using a Merkle tree construction, allowing users to verify that their individual balance was included in the reserve snapshot by tracing the path to the published Merkle root. While the report shows a small surplus, it is not a full financial audit and does not cover all liabilities.

Accumulation Against a Difficult Backdrop

The uptick in user holdings came during a turbulent period for Bitcoin. During the week of May 23 to May 29 alone, global cryptocurrency-based exchange-traded products lost $1.67 billion, the second-largest weekly outflow of 2026. Spot Bitcoin ETFs had attracted $3.29 billion in net inflows over two consecutive months before suddenly reversing course.

That context makes the on-exchange accumulation figure more notable. While institutional investors pulled back from ETF products, Binance users were quietly adding to their Bitcoin positions, suggesting retail and exchange-based demand remained resilient through the period.

The limitations of Proof of Reserves are well documented. The proof shows assets on a specific date and does not address liabilities the exchange may owe outside the snapshot, such as loans, off-balance-sheet obligations, or derivatives margin shortfalls. Even so, the month-on-month increase in user BTC balances offers a concrete on-chain signal of where retail sentiment stood heading into June.
