BlackRock’s IBIT Moves $203 Million in Bitcoin to Coinbase Prime

U.S. spot bitcoin ETFs have become a major channel for institutional participation in the crypto market since their January 2024 launch. BlackRock’s IBIT ranks among the largest, and its flows are often viewed as a gauge of bitcoin demand and Wall Street risk appetite.

The latest trading data as of July 20, 2026, showed that U.S. spot bitcoin ETFs recorded $231 million in single-day net outflows, while BlackRock’s IBIT saw outflows of about $300 million. Investors were sitting on average unrealized losses of 40%. Analysts also warned that bitcoin could fall to $55,000 in August as capital shifts toward AI infrastructure and chip stocks.

BlackRock’s iShares Bitcoin Trust, or IBIT, is a U.S. spot Bitcoin ETF launched in January 2024 that gives institutions exposure to Bitcoin prices through brokerage accounts. Dark pools allow large investors to privately match sizable trades. More than $1.2 billion changed hands in this transaction, showing how ETFs have become a key channel for institutions to rapidly move money into and out of Bitcoin, affecting market sentiment and liquidity.

At 10:30 a.m. ET on May 26, 2026, an anonymous seller sold 29.2 million IBIT shares in a dark pool at $43.16 each, for a total of $1.26 billion. The price was a $1.01 discount to the market, meaning the seller accepted $29.5 million less to exit immediately. NYDIG said on May 29 that the trade appeared to be the exit of a large directional position. Bitcoin fell 2.8% the following day, while U.S. spot ETFs recorded net outflows of $333.6 million that day, though no causal link has been established.

BlackRock's iShares Bitcoin Trust (IBIT) quickly became the largest U.S. spot Bitcoin ETF after its January 11, 2024, launch. Its fund flows are regarded as an important gauge of institutional risk appetite, with large withdrawals typically adding pressure to Bitcoin's price and market liquidity.

IBIT recorded net outflows of about $528 million on July 15, its second-largest single-day outflow since launch. U.S. spot Bitcoin ETFs collectively lost more than $733 million that day. Escalating tensions in the Middle East and macroeconomic uncertainty boosted demand for safe-haven assets, while Bitcoin briefly fell below $75,000, indicating that institutional investors were reducing their crypto exposure.

BlackRock’s spot Bitcoin and Ethereum ETFs use Coinbase Prime as their primary custody and trading platform. Transfers to the exchange typically involve portfolio rebalancing or investor redemptions. Because flows from large institutions can affect market supply and demand, such on-chain movements draw close scrutiny, although a transfer alone does not mean a sale has been executed.

On-chain data on July 20 showed that addresses linked to BlackRock ETFs transferred 2,200 BTC and 2,417 ETH to Coinbase Prime, worth about $150 million in total. The market is concerned that the assets could create spot selling pressure. Attention will now turn to flows from Coinbase wallets and the ETFs’ daily net subscription and redemption data.
