Thursday saw spot Bitcoin exchange-traded funds in the United States witnessing a combination of inflows and outflows, resulting in the 13th consecutive day of total net inflows reaching $48.71 million. Fidelity and Ark Invest stood out with notable movements in their respective ETFs.

Fidelity's FBTC led in net inflows with $119 million, with Ark Invest's ARKB experiencing a historic net outflow of $100 million, marking its largest single-day outflow since January based on SoSoValue data.

Leading spot Bitcoin ETF by net assets, BlackRock's IBIT, reported modest net inflows of $2 million. Grayscale's GBTC, currently the second-largest fund, witnessed stability in net flows. Bitwise's BITB recorded an increase of $26 million, while Invesco and Galaxy Digital's bitcoin ETF saw net inflows of $2 million.

The irregular activity in spot Bitcoin ETFs seems to be influenced by investor uncertainty concerning the Federal Reserve's interest rate trajectory, especially in the lead-up to key economic reports expected on May 31, according to Rachael Lucas, Crypto Analyst at BTC Markets.

Lucas remarked, "If U.S. inflation figures surpass predictions and there is a rise in personal income and spending trends, it may dampen investor confidence regarding a potential Fed rate cut in September."

"A more hawkish stance by the Federal Reserve could impact the demand for riskier assets, such as Bitcoin and related ETFs," he emphasized.

Over the past 13 days, US spot Bitcoin ETFs have attracted total net inflows exceeding $2 billion, marking the second-longest positive streak since their introduction.
