Bitcoin ETFs Attract Over $2 billion in Weekly Inflows: What’s Driving the Gains?

Bitcoin ETFs in the U.S. recorded $2.39 billion in net inflows over the past week, according to data from Farside Investors, marking one of the strongest capital surges since their launch.

Leading the pack was BlackRock’s iShares Bitcoin Trust (IBIT), which brought in an impressive $2.57 billion—more than the sector’s total net inflow—effectively absorbing outflows from other funds.

The gains were largely driven by renewed institutional confidence as Bitcoin hovered near its all-time high of $120,000. At the same time, IBIT’s continued dominance reflects investor rotation into lower-cost and more liquid ETF structures. Capital appears to be flowing out of legacy vehicles like Grayscale’s GBTC, which saw $122.5 million in redemptions, and ARK 21Shares’ ARKB, which lost $119.6 million.

What’s driving the gains?

Several key factors are fueling this surge. Optimism around potential interest rate cuts has lifted risk appetite broadly, while continued ETF inflows signal that institutions view Bitcoin as a maturing asset class.

Further boosting investor sentiment, President Donald Trump recently signed the long-awaited GENIUS Act, aimed at providing clear regulatory guidance for stablecoins and digital asset innovation in the U.S. The law also included provisions to support broader crypto infrastructure development and affirmed that Americans have the right to self-custody digital assets—moves widely celebrated across the crypto community.

The recent approval of new ETFs may have added further legitimacy to the crypto space, drawing more inflows across the board. Additionally, with Bitcoin supply on exchanges at multi-year lows and long-term holders showing little desire to sell, the tightening supply dynamics are reinforcing upward price pressure—making ETFs an attractive vehicle for exposure.

Smaller inflows into products like HODL, BITB, and BTCW helped balance the market, but the majority of inflows are clearly consolidating around a few top-performing funds. The strong weekly numbers suggest institutional buyers are not just returning—but accelerating exposure through spot ETFs as momentum builds around Bitcoin’s next potential breakout.
