Bitcoin ETF IBIT Rakes in $2.48B Weekly Inflows as U.S. Fund Rotation Accelerates

Wall Street’s latest crypto darling—the iShares Bitcoin Trust (IBIT)—just vacuumed up $2.48 billion in fresh capital this week as institutional money continues its desperate scramble for digital gold exposure. Meanwhile, legacy funds hemorrhage assets faster than a DeFi hack drains liquidity pools.

The rotation into crypto ETFs hits warp speed as TradFi finally admits what crypto natives knew in 2018—you either stack sats or get left behind. IBIT’s monster inflows now account for nearly 30% of all Bitcoin ETF flows since January, proving even Wall Street sharks need blockchain training wheels.

Analysts whisper this could be the start of the great wealth transfer—from boomer bonds to digital assets. But let’s be real: these are the same geniuses who missed Bitcoin at $200. Place your bets accordingly.

• IBIT leads Bitcoin ETF inflows with $2.48B, now eighth in YTD ETF flow rankings.
• Grayscale’s GBTC sees continued outflows as investors shift to low-cost alternatives.
• VOO tops all ETFs with $3.93B in weekly inflows despite negative YTD performance.

Investor flows into U.S.-listed exchange-traded funds (ETFs) totaled $12.98 billion over the past week, signaling sustained participation across equities, fixed income, and digital asset segments. BlackRock’s iShares Bitcoin Trust (IBIT) drew particular attention, recording $2.48 billion in inflows, the second-highest among all ETFs.

IBIT’s performance stood out with $2.48 billion in inflows over the past week, contributing to $3.83 billion for the month. The fund’s year-to-date return of 4.03% and increasing demand have propelled it to eighth place in 2025’s ETF Flow rankings, a steep climb from being outside the top 50.

One interesting note also is $IBIT taking in SO much more then the rest of them (altho 10 of them have seen inflows). Usually there’s much more parity tho. Why is this? My theory, return of the HF basis trade and some big fish biting after the decoupling and subsequent rally. pic.twitter.com/S4X1hsGL7B

Its assets under management now total $59.64 billion, indicating its dominance among U.S.-based Bitcoin ETFs. According to analysts, large inflows could be attributed to a resurgence in hedge fund basis trading strategies and interest from institutional investors following the decoupling between Bitcoin and broader market indices.

Despite the influx being concentrated in a single fund, at least ten spot Bitcoin ETFs reported net inflows for the week, suggesting sector-wide interest. However, the disproportionate allocation toward IBIT marks a shift in market preference toward low-cost, high-liquidity options.

Grayscale and Fidelity Show Contrasting Flows

While IBIT gained traction, Grayscale’s GBTC saw continued net outflows. Over the past month, GBTC recorded a loss of $210.82 million, including a $58.61 million weekly outflow. The trend reinforces ongoing investor migration away from legacy products with higher fees.

Fidelity’s FBTC experienced a $201.09 million outflow for the week, despite a net monthly inflow of $151.71 million. This variance indicates short-term fluctuations in sentiment, possibly tied to volatility or rebalancing strategies within institutional portfolios.

Smaller funds such as HODL and BTCW posted modest activity. HODL saw a net monthly gain of $30.18 million, while BTCW lost $17.12 million. Franklin Templeton’s BRRR ETF followed a downward pattern with $26.52 million in monthly outflows.

Cumulatively, spot Bitcoin ETFs attracted nearly $4 billion in net inflows for the month, with IBIT accounting for most of that capital.

Traditional ETFs Hold Ground Amid Digital Surge

VOO from Vanguard collected the most overall ETF inflows of the week with $3.93 billion. Even though the fund has a –3.02% YTD return, it still enjoyed continued investor support seeking long-term exposure to U.S. large-cap equities.

International-focused funds also gained momentum. Newfound interest in non-U.S. markets was evident in gains of $1.37 billion for the iShares CORE MSCI Total International Stock ETF (IXUS) and $1.06 billion for the iShares International Quality ETF (IQLT). In fixed income, the SPDR Bloomberg 1–3 Month T-Bill ETF (SGOV) amassed $1.21 billion in inflows, reflecting continued appetite for Treasuries with minimal exposure to longer duration, as those in power continue to ponder rate policy.

Despite a total return market-wide decline of –211.22% YTD on specific metrics, investors are not pulling money out of the markets but reallocating their capital with an eye toward liquidity, diversification and asset efficiency.
