Binance saw its largest weekly Bitcoin withdrawal in over three years during the last week of September. At the same time, major holders boosted their stablecoin balances on the platform by roughly 40% compared with mid-August.

Outflow details

Onchain analytics from CryptoQuant showed that Binance’s net Bitcoin outflow totaled 23,137 BTC for the seven days through Sept 27. This figure marks the biggest weekly drop since June 2023, when the exchange lost 44,942 BTC in a single week. Since Sept 20, Binance’s Bitcoin reserves have fallen by nearly 40,000 BTC. CryptoQuant noted that such outflows often signal longer-term accumulation, as moving Bitcoin off an exchange tends to reflect investment rather than trading intent. The firm also pointed out that a similar pattern in June 2023 preceded a rise in BTC/USD from $26,300 to $30,500, delivering new 12-month highs during the recovery from the 2022 bear market.

Bitcoin has been trading between $82,500 and $87,400 since Sept 21, with the 2026 yearly open at $87,570 acting as overhead resistance. Analysts suggest that if selling pressure continues to ease, the current accumulation could be enough to push the asset out of this consolidation band.

Stablecoin inflows

Separate data from CryptoQuant revealed that whale-controlled entities increased their rolling 30-day stablecoin inflows to Binance by about 40% between Aug 15 and the end of September. The amount rose from $21.7 billion to $30.5 billion. This growth follows a period of reduced inflows after the October 2025 peak, when whale stablecoin deposits on the exchange exceeded $61 billion. Because stablecoins on exchanges are viewed as dry powder awaiting deployment into crypto assets, the rise indicates mounting interest in increasing capital exposure.

Why it matters

The combination of rising Bitcoin withdrawals and growing stablecoin holdings on Binance points to a shift in investor behaviour. Traders appear to be moving Bitcoin off the exchange for long-term holding while positioning liquid assets for future purchases. If the outflow trend persists and seller interest remains weak, analysts believe the market may have the momentum needed to break Bitcoin out of its present range and resume upward movement.
