Bitcoin ETFs Attract $767M as BlackRock Drives Majority of Inflows

• Bitcoin ETFs recorded $767 million in inflows over five days.
• The IBIT ETF from BlackRock accounted for more than $600 million of the total inflows.
• BTC trades near $73,500 as traders watch potential breakout levels.

Institutional demand for digital assets strengthened last week as spot Bitcoin exchange traded funds recorded their largest inflow streak of the year.

According to market data from SoSoValue, spot Bitcoin ETFs attracted approximately $767 million in net inflows between March 9 and March 13.

The majority of that demand came from the BlackRock managed iShares Bitcoin Trust (IBIT), which absorbed more than $600 million in new capital during the period.

BlackRock’s IBIT represented roughly 78% of all net inflows across Bitcoin ETF products during the week.

The fund now holds more than $55 billion in assets, reinforcing its position as the largest spot Bitcoin ETF in the market.

Other ETF products saw mixed flows. The Grayscale GBTC fund recorded around $25.9 million in outflows, making it the only major Bitcoin ETF product to experience meaningful selling pressure during the same period.

Ethereum investment products also attracted new capital. Spot Ethereum ETFs recorded approximately $160.9 million in inflows, with the Fidelity Ethereum Fund (FETH) contributing roughly $90 million of that total.

Despite the broader trend of institutional inflows into major cryptocurrencies, funds tracking XRP recorded $28 million in net outflows, making it the only major crypto ETF category to post weekly declines.

In the spot market, Bitcoin traded near $73,500 at the time of writing. Analysts note that the asset is approaching a key technical resistance area around $75,000, which has capped upward moves several times in recent weeks.

Some traders suggest that a breakout above this level could trigger short liquidations if bearish positions are forced to close.

The latest ETF inflows highlight continued institutional interest in Bitcoin despite recent volatility earlier in the year.

Market participants are now watching whether sustained capital inflows into spot Bitcoin ETFs can support a move above key resistance levels in the coming weeks.
