A wallet linked to Andreessen Horowitz's crypto arm withdrew 25,560 Ethereum, worth about $43 million, from Binance. The transaction, flagged by on-chain analytics platform Onchain Lens, is the largest ETH withdrawal in a series of moves by the venture firm this month. It adds to a growing pattern of institutional self-custody actions seen throughout 2026.
Withdrawal pattern
Just days earlier, on June 23, an a16z-associated wallet pulled 12,780 ETH, valued at roughly $21.22 million, from the same exchange. The firm has also moved other assets off exchanges: earlier in June, related entities withdrew over 224,000 HYPE tokens, worth approximately $15 million, within a single 24-hour period. A16z has not commented publicly on these transactions.
The simplest explanation is risk management. Since the collapse of FTX in late 2022, institutional players have grown wary of keeping large balances on centralized exchanges. Self-custody eliminates counterparty risk—the chance that the exchange fails, gets hacked, or freezes withdrawals. A16z has been investing in blockchain companies since 2013, making it one of the longest-tenured institutional players in crypto.
Market implications
ETH has recently traded in a range between $1,660 and $1,806. Every chunk of Ethereum that moves off exchanges reduces the immediately available supply for trading, meaning fewer tokens on order books. That can make it easier for buying pressure to push prices up, but the liquidity implications cut both ways: if a sudden wave of selling hits a thinner order book, the downside could be sharper than it would be with deeper liquidity. The trend of institutional self-custody is likely to continue as firms prioritize control over their assets.
