A wallet linked to the US government moved 12,267.02 BTC, worth about $1.01 billion, on October 8. The coins eventually landed in Coinbase deposit addresses.
Following the billion-dollar breadcrumbs
Arkham Intelligence identified the source wallet as tied to the government’s seizure from the 2016 Bitfinex hack. That case remains one of the largest crypto recoveries tied to a single theft.
The coins did not travel straight to Coinbase. They first hopped through a series of unlabeled addresses before reaching deposits that Arkham tags as belonging to the exchange.
Those destination addresses connect to Coinbase Prime, the exchange’s platform used mainly for institutional custody.
The October 8 move was the biggest piece of a wider pattern. Between October 6 and 8, government-linked wallets moved somewhere between 17,795 and 21,500 BTC, valued at approximately $1.5 to $1.78 billion at current prices.
Galaxy Research separately tracked 9,261 BTC, roughly $770 million, flowing to Coinbase Prime between October 6 and 7.
Roughly half of the transferred coins connect to Bitcoin seized in the Bitfinex case. Other portions trace back to forfeiture proceedings, including those tied to the FTX and Alameda collapse.
Custody consolidation, not a fire sale
Analysts at both Galaxy Research and Arkham characterized the activity as custody consolidation. The Department of Justice and the US Marshals Service primarily manage the government’s seized Bitcoin, and they rely on Coinbase Prime infrastructure to do it.
The timing still raised eyebrows. Bitcoin fell approximately $4,000 as the transfers unfolded.
No confirmed liquidations have been tied to the movements, however.
How big is the government’s Bitcoin pile
Estimates put the US government’s seized Bitcoin holdings at around 307,000 to 325,000 BTC, valued at roughly $25 billion.
The lower estimate of around 307,000 BTC would represent a ~6.5% decline from late 2025.
The government has an explicit prohibition on sales from its Strategic Bitcoin Reserve, which shapes how traders interpret any movement from official wallets.
What this means for the market
Arkham’s labeling established that the funds reached Coinbase deposits. Galaxy Research and Arkham both read the pattern as custody consolidation. Neither confirmed a sale.
The roughly $4,000 drop shows how quickly the market can react to government wallet activity before anyone has confirmed what is happening. A headline about a billion-dollar transfer can move prices faster than analysts can trace the coins.
Coinbase’s role as custodian for the Department of Justice and the US Marshals Service puts the exchange at the center of how seized crypto gets handled, concentrating a sizable amount of government-controlled Bitcoin with one institutional provider.
Changes in the estimated size of the government’s holdings will be the real tell. If the figure keeps shrinking from the 307,000 to 325,000 BTC range, the conversation shifts from custody logistics to actual supply hitting the market.
