The largest Bitcoin wallet in existence is owned by Binance. As per Arkham Intelligence, a cold wallet controlled by Binance stored approximately 248,598 BTC as of July 4, 2026.
This amount represents nearly 1.24% of the total circulating supply of Bitcoin, concentrated in a single wallet.
The wallet address is 34xp4vRoCGJym3xR7yCVPFHoCNxv4Twseo, and it started receiving Bitcoin on October 18, 2018.
Since that initial deposit, it has recorded 5,531 incoming transactions, with the latest deposit noted around July 3, 2026, according to Arkham’s analysis.
In contrast, outbound movements reveal a different trend. No transfers have been sent from this wallet since January 7, 2023.
This behavior aligns with typical cold storage practices. A cold wallet keeps its private keys offline, enhancing security and protecting against potential hacks originating from internet-connected devices.
Besides the leading wallet, Binance has another significant cold wallet at address 3M219KR5vEneNb47ewrPfWyb5jQ2DjxRP6, which is believed to hold between 172,000 and 175,000 BTC.
The overall distribution highlights uneven Bitcoin ownership; Arkham’s data shows that the twelve largest wallets collectively hold about 1.35 million BTC, accounting for roughly 6.72% of the complete supply.
According to the research, Binance’s cold wallets are designed to securely store customer assets offline. The funds in this wallet mainly represent deposits pooled from various users for enhanced security.
Cold storage is widely regarded as a reliable method in the industry for mitigating risk. By holding private keys offline, exchanges protect themselves from cyberattacks that have historically targeted online wallets.
A key observation is the inactivity regarding outbound transactions since January 7, 2023, suggesting that Binance has not needed to utilize this reserve for processing withdrawals.
The research emphasizes that such large holdings could impact Bitcoin’s market price dynamics if they were ever liquidated. Additionally, the idle assets may limit market liquidity, especially with Bitcoin’s capped supply.
The consistent influx of deposits into this primary wallet, most recently around July 3, 2026, reflects user behavior trends. Ongoing deposits into cold storage indicate that clients may prefer leaving their coins on the platform rather than withdrawing them.
