Roughly 31,782 bitcoin, worth about $2.52 billion, left centralized exchanges over the past seven days, the largest multi-day withdrawal wave since 2023, according to on-chain data from Coinglass and CryptoQuant. Binance alone shed close to 19,500 BTC as holders moved coins into self-custody while bitcoin traded in the mid-$80,000s.
The single-day record also fell to Binance. More than 13,800 BTC, about $1.16 billion at recent prices, left the platform in one session, its highest daily net outflow in three years. Coinbase Pro followed with roughly 6,700 BTC and Kraken with about 2,816 BTC. Bitfinex also posted net withdrawals.
Binance bitcoin reserves dropped to about 685,000 BTC from 705,000 BTC as of Sept. 25, and the exchange weekly average netflow stayed negative at around 2,000 BTC. The platform holds an estimated 30 percent of all exchange-accessible bitcoin, so its outflows carried unusual weight in the weekly total.
CryptoQuant analyst Amr Taha put the combined three-day net outflow across Binance, Coinbase, Kraken and Bitfinex at $2.52 billion between Sept. 22 and 24. On Sept. 22 alone, the four exchanges saw $1.574 billion leave, with Binance accounting for $1.19 billion of it.
Reserves and sell-side liquidity
Analysts read the pattern as accumulation rather than exit selling. Falling exchange reserves historically track with reduced sell-side liquidity, a relationship Glassnode and CryptoQuant data have supported through repeated cycles. The 2026 pattern has been consistent: reserves grind lower, with sharp spikes on days when large holders pull coins off platforms.
Addresses holding 1,000 BTC or more have grown during the withdrawal wave, which on-chain analysts treat as a sign of conviction among larger players. Gokhshtein Media desk noted the volume mirrors accumulation phases seen after the January 2024 spot ETF approvals.
Per-exchange breakdown of last week outflows, per Coinglass and CryptoQuant data:
| Exchange | 7-day net outflow | Notable detail |
|---|---|---|
| Binance | ~19,500 BTC | Record single-day outflow above 13,800 BTC |
| Coinbase Pro | ~6,700 BTC | Institutional-weighted venue |
| Kraken | ~2,816 BTC | Net outflows all week |
| Bitfinex | net outflow | Smaller share of total |
Two drains at once
The exchange exodus ran alongside continued institutional demand. US spot bitcoin ETFs took in $3.8 billion over three weeks earlier this month and logged their best week since October 2025 in the week just ended. Both channels remove coins from tradable exchange supply: fund custodians buy and hold, and self-custody holders withdraw.
The two flows point in the same direction for order books. ETF shares are bought with cash and backed by coins held at custodians, so ETF demand never shows up as exchange sell pressure. Self-custody withdrawals do the same for retail and smaller institutions.
Price context
Bitcoin pulled back from a recent high near $87,400 and traded in the mid-$80,000s through the withdrawal window. The outflows happened during strength, not after a crash, which is why analysts at CryptoQuant framed them as buyers securing positions rather than holders fleeing.
Reduced liquid supply cuts both ways. With fewer coins on order books, the same dollar of demand moves price further, but the same panic does too. Analysts cautioned that outflow waves in past cycles have sometimes marked local tops when sentiment peaked alongside them.
The Fed next rate decision lands Wednesday, and markets put roughly 60 to 70 percent odds on a 25 basis point move depending on the pricing source. Bitcoin reaction to that print will test how much of the recent bid survives.
Binance weekly average netflow has stayed negative since the spring, per CryptoQuant, suggesting the current wave extends a trend rather than starting one. Exchange reserves across major platforms have declined steadily through 2026.
The withdrawal data comes from Coinglass, which aggregates exchange wallet movements, and from CryptoQuant analysts who publish netflow series for the major venues. Figures differ slightly between providers because of how each counts internal transfers and custody wallets, but the direction agrees across all of them.
For exchanges, the trend has revenue implications. Trading volume, not custody, drives venue economics, and coins sitting in self-custody generate fees only when they return to trade. Binance has leaned into off-exchange products and its own custody offering to keep those balances inside its ecosystem.
Whether the coins return depends on price. In past accumulation phases, withdrawn coins stayed off exchanges for months. If bitcoin retests its late-August high near $87,400, some of that supply could come back to market into strength, easing the squeeze the outflows created.
What the custodians see
ETF custodians have become the quiet counterweight to the exchange drain. When a spot ETF creates new shares, the custodian buys bitcoin and parks it in cold storage that never touches an exchange wallet. BlackRock IBIT alone accounts for well over half of the roughly $103 billion now held across US spot bitcoin ETFs, per CoinDesk reporting earlier this month.
That structure means ETF demand and exchange reserves move independently. A fund can absorb weeks of selling without any coin appearing on an order book, which compresses the visible supply picture further. Analysts who track both series say the combination of falling reserves and steady ETF creations is the tightest setup since the launch quarter of the funds in early 2024.
Derivatives positioning tells a similar story. Open interest across crypto futures rose to about $430 billion this week, and the volatile session around the CPI print triggered roughly $897 million in liquidations, split almost evenly between longs and shorts. Traders positioning for the Fed decision have kept leverage elevated on both sides.
Historical precedent and its limits
Large outflow waves have appeared at several points in the last cycle, and not all of them marked bottoms. The 2021 accumulation phases were followed by further gains, but the outflow spikes of early 2022 came as the market rolled over. Direction of flows alone has never been a complete signal.
What differs this time is the institutional layer. In prior cycles, exchange outflows mostly reflected retail moving to hardware wallets. Now a meaningful share of removed supply sits in regulated fund structures with ongoing creation and redemption, which changes how quickly coins could re-enter the market if sentiment turns.
Korean and Japanese venues have seen similar patterns. Upbit reserves fell after the JPYC listing frenzy left 21,219 buyers underwater on the yen stablecoin, and Japanese institutional desks have been moving holdings into qualified custody ahead of the tokenized securities rollout planned for 2027.
For now, the numbers favor the bulls. Supply on exchanges is down, ETF demand is up, and price has held the mid-$80,000s through a week of mixed macro data. The test comes Wednesday, when the Fed decides and the market finds out whether the accumulation thesis survives contact with higher rates.
