Top 10 Weekly ETF Inflows in the U.S. Are Surging! BlackRock’s Bitcoin ETF pulls in nearly $1 billion in a single week, and options are also performing strongly

BlackRock’s IBIT Bitcoin Spot ETF attracted nearly $1 billion in weekly inflows, entering the top ten in U.S. ETF inflow rankings for the first time. IBIT’s performance is now comparable to traditional index funds like the S&P 500.

The digital gold craze heats up, with IBIT rapidly attracting close to $1 billion in weekly funds into the top ten

BlackRock’s IBIT Bitcoin Spot ETF demonstrated remarkable capital attraction in late April 2026. According to the latest market data from Bloomberg analyst James Seyffart, the fund has officially entered the top ten in weekly U.S. ETF inflows. In the week ending April 24, IBIT recorded approximately $994 million in net inflows, successfully ranking ninth in the U.S.

This record reflects investor enthusiasm for cryptocurrency assets, showing that IBIT has the strength to compete alongside top-tier index funds. Currently, Vanguard’s S&P 500 ETF (VOO) and SPDR’s S&P 500 ETF Trust (SPY) remain at the top of the list, maintaining market leadership. However, IBIT, as a new asset class, is rapidly rising, catching Wall Street’s attention.

Looking back at IBIT’s performance since its launch, its growth trajectory is a milestone. To date, the fund’s total cumulative inflows have exceeded $65.3 billion, indicating sustained long-term demand for Bitcoin products. Over the past three months, IBIT has accumulated $2.43 billion in inflows, showing that investor interest has not waned with market volatility but instead continues to grow steadily.

Examining specific daily data, on April 23, IBIT received $167 million in capital, accounting for most of the $223 million total inflow into U.S. Bitcoin spot ETFs that day. For investors seeking to access the crypto market through traditional securities channels, IBIT offers a simple, regulated tool, allowing the public to participate in Bitcoin price movements via the stock market.

Risk-on wave drives tech and crypto assets to soar together

The current market environment is described by Bloomberg ETF analyst James Seyffart as a strong risk-on rebound. This week, investors demonstrated high risk appetite, pouring funds into growth assets. The total U.S. ETF inflows in just seven days surpassed $35.39 billion, with capital flows highly concentrated. Bitcoin-related products performed well, and technology and innovation sectors also attracted significant investment. ARK Innovation ETF (ARKK) saw over $1.23 billion in weekly inflows, ranking fourth, while the Technology Select Sector SPDR Fund (XLK) followed closely with $1.12 billion, ranking fifth.

This capital flow pattern reflects investors’ collective optimism about high-growth sectors. While ETFs tracking the S&P 500 continue to attract safe-haven and benchmark allocations, more speculative or growth-oriented products like ARKK, XLK, and IBIT are also gaining strength, painting a picture of market confidence in future economic growth. This trend indicates that Bitcoin’s role in portfolios is shifting; it is increasingly viewed by traditional investors as an alternative to growth stocks or tech stocks.

IBIT open interest surpasses foreign platform Deribit

The institutionalization of the Bitcoin market has recently reached a key turning point. According to data from decentralized volatility protocol Volmex, the regulated options market linked to BlackRock’s IBIT has officially overtaken Deribit, a long-dominant overseas exchange.

As of Friday, April 24, the open interest (OI) of IBIT options traded on Nasdaq reached $8B, slightly higher than Deribit’s $8B. Considering Deribit has been deeply involved in Bitcoin options since 2016, and IBIT-related options products have only been launched for about two years, this scale-up signifies that U.S.-regulated derivatives infrastructure now has the capacity to dominate the global market.

Deribit global retail sales and business director Sidrah Fariq stated that the rise of IBIT is a positive development for the entire crypto derivatives ecosystem.

Since U.S. retail investors cannot directly access platforms like Deribit, IBIT options provide them with a regulated pathway to leverage and gain exposure to options risks. In the current uncertain macroeconomic environment—characterized by supply chain disruptions, energy shocks, and geopolitical risks—investors’ demand for hedging strategies is growing. The maturation and deepening of IBIT options markets will attract more Wall Street institutions to explore digital assets, fostering a more mature price discovery mechanism and reducing the impact of market anomalies.

Bullish outlook behind high implied volatility and hedging demand

Although IBIT and Deribit are now comparable in market size, their investor structures and strategic tendencies differ significantly. Data shows that IBIT options markets exhibit a more bullish sentiment. In IBIT call options holdings, most contracts bet that Bitcoin will rise to approximately $109,709 in the short term, about 41% higher than the current spot price of around $77,400. In contrast, Deribit’s options positioning, while also optimistic, targets more conservative levels around $106,000. This difference reflects how retail and institutional investors in the U.S. are using options to speculate on upward potential.

Additionally, IBIT investors tend to hold positions for longer periods. Volmex’s analysis indicates that IBIT’s average open contract expiration date is concentrated in October 2026, whereas Deribit’s contracts mainly expire in August. This suggests IBIT holders are more likely to be long-term ETF investors rather than traders seeking short-term arbitrage.

IBIT’s implied volatility (IV) is currently higher than Deribit’s. Analysts attribute this to ETF holders lacking easy access to direct Bitcoin shorting avenues, leading them to buy put options as hedges. This structural hedging demand pushes up option premiums, and the involvement of diverse strategies helps sustain a positive feedback loop in Bitcoin markets. As traditional giants like Morgan Stanley join the competition, the future rivalry in crypto ETFs and derivatives markets will intensify.
