According to Cointelegraph: Spot Bitcoin exchange-traded funds (ETFs) based in the United States have experienced their largest inflows since mid-July, with over $1.1 billion recorded in the week starting September 23. Leading the charge were Bitcoin products from BlackRock, ARK 21Shares, and Fidelity, which saw inflows of $499 million, $289.5 million, and $206.1 million, respectively, according to Farside Investors.

The week's peak was reached on September 27, when spot Bitcoin ETFs recorded $494.4 million in inflows, the best-performing day since June 4. In addition, spot Bitcoin ETFs registered $366 million in inflows on September 26.

While BlackRock, ARK 21Shares, and Fidelity led the way, other Bitcoin ETFs from Invesco, Galaxy, Franklin Templeton, Valkyrie, and VanEck also saw inflows ranging between $5.7 million and $33.3 million. However, WisdomTree's Bitcoin Fund did not report any inflows during the period. Since their launch in January, the cumulative inflows for all 11 spot Bitcoin ETFs have now reached $18.8 billion.

In addition to Bitcoin ETFs, US spot Ether ETFs also had a strong week, with $85 million in inflows—marking their largest inflows since August 5-9. Since their launch on July 23, Ethereum ETFs have accumulated a little over $1.1 billion, which factors in $2.9 billion in outflows from the Grayscale Ethereum Trust.

The increase in Bitcoin ETF inflows came after the US Federal Reserve's interest rate cut on September 18, which has positively impacted the cryptocurrency market. Since then, Bitcoin has rallied 13.8%, reaching $65,800, according to CoinGecko data. The cryptocurrency now stands just 10.8% below its all-time high of $73,738, which was set on March 14.

As the fourth quarter approaches, historical data from CoinGlass indicates that Bitcoin has seen gains of 50% or more in the fourth quarter of five out of the last nine years, highlighting a potential bullish trend.
