Binance Bitcoin Outflows Hit Three-Year High as Whale Stablecoin Deposits Rise
Key Takeaways
- •Binance recorded net Bitcoin outflows of 23,137 BTC in the seven days through September 27, 2026, the largest weekly outflow since June 2023, when reserves dropped by 44,942 BTC.
- •Binance's Bitcoin reserves have declined by nearly 40,000 BTC since September 20, 2026, a closely watched indicator of sell-side supply on centralized exchanges.
- •CryptoQuant said the withdrawals could indicate accumulation, noting that Bitcoin held off exchanges is generally less available for immediate sale, though a single prior episode does not establish a repeating pattern.
- •Large holders increased rolling 30-day stablecoin inflows to Binance by 40%, from $21.7 billion to $30.5 billion, between August 15 and the end of September 2026.
- •The on-chain data does not confirm that deposited stablecoins will be used to buy Bitcoin, nor does it reveal where withdrawn Bitcoin moved or the intentions of the holders, while Bitcoin has traded between approximately $82,500 and $87,500 since September 21.
Bitcoin withdrawals from Binance, the world's largest cryptocurrency exchange, climbed to their highest weekly level in more than three years in late September 2026, while large holders simultaneously increased their stablecoin deposits on the platform, according to data from on-chain analytics firm CryptoQuant.
The exchange recorded net Bitcoin outflows of 23,137 BTC in the seven days through September 27, 2026 — the largest weekly outflow since June 2023, when the exchange's Bitcoin balance fell by 44,942 BTC. CryptoQuant's data further showed that Binance's Bitcoin reserves have declined by nearly 40,000 BTC since September 20, 2026. Because Binance is the largest crypto exchange by trading volume, shifts in its Bitcoin reserve are closely watched as a gauge of sell-side supply across centralized exchanges.
CryptoQuant said the withdrawals could indicate accumulation, as Bitcoin held away from exchanges is generally less readily available for immediate sale. The firm pointed to a comparable episode in June 2023, when a similar decline in Binance's reserves was followed by a rise in Bitcoin's price from about $26,300 to $30,500 over the following week. A single prior episode does not, by itself, establish a repeating pattern.
At the same time, whale entities have been moving more stablecoins onto the exchange. CryptoQuant reported that large holders increased their rolling 30-day stablecoin inflows to Binance by 40% between August 15, 2026, and the end of September 2026, from $21.7 billion to $30.5 billion. Rolling 30-day inflows measure the total amount deposited over the trailing month.
Stablecoins held on exchanges can provide liquidity for purchases of crypto assets. However, the on-chain data does not establish that the deposited funds will be used to buy Bitcoin, nor does it identify where the withdrawn Bitcoin has been moved or the intentions of the holders behind either flow.
According to CryptoQuant's figures, Bitcoin has traded in a range between approximately $82,500 and $87,500 since September 21, 2026. Subsequent updates to CryptoQuant's reserve and inflow metrics will show whether either trend continues.
