BlackRock added about $612.1 million in Bitcoin over five days, according to Arkham Intelligence data. The purchases were made through iShares Bitcoin Trust (IBIT), which led U.S. spot ETF inflows during the period.
The accumulation continued despite geopolitical tension after talks between the United States and Iran ended without agreement. The meeting lasted 21 hours and took place in Pakistan. The outcome did not slow ETF-related demand.

According to on-chain data, the valuation of BlackRock’s cryptocurrency portfolio is about $62.75 billion as of April 13, 2026. Bitcoin represents the highest proportion. The number of assets held is close to 788,927 BTC, which is valued at $56 billion.
Ethereum is the second largest asset in the portfolio. There are over 3 million ETH held by BlackRock, valued at around $6.7 billion. Other tokens and stablecoins account for a smaller portion of total holdings.
The transaction data indicates that a majority of transactions go via Coinbase Prime. The custodian and execution services of this exchange are used for executing the transactions. It processes nearly all deposits and withdrawals linked to these operations.
The value of the portfolio has been decreasing since its peak of over $110 billion reached in late 2025. This is attributed to the general market decline. There is no indication of large-scale selling from available data.
According to CoinMarketCap, Bitcoin is trading at $70,740 at the time of writing. The price is still lower than the average purchase price of $89,000 for IBIT holders, causing an unrealized loss of approximately $12 billion.
However, ETFs continue to see net inflows. Daily data shows mixed flows involving both inflows and outflows. Over time, the trend is still positive.
According to SoSoValue data, the total net inflow for US Spot Bitcoin ETFs amounted to $240.42 million on April 10. The total cumulative inflows are now approximately $56.74 billion. The combined net asset value is at $94.92 billion.
IBIT continues to be the largest fund in the category, with about $63.73 billion in total inflows and a portfolio of approximately $57.81 billion. Other competing funds from Fidelity Investments and Grayscale Investments lag behind in total inflows.
