U.S. spot Bitcoin ETFs are seeing fresh demand again, with funds recording about $467.38 million in net inflows on May 5, 2026. The move marked the fourth straight day of positive ETF flows, showing that institutional and traditional market interest in Bitcoin remains active.
The biggest buyer was BlackRock’s iShares Bitcoin Trust, known as IBIT. The fund brought in around $251.45 million in one day, making it the strongest performer among U.S. spot Bitcoin ETFs for the session.
BlackRock was not alone. Fidelity’s FBTC also posted strong inflows of about $133.20 million, while Ark Invest’s ARKB added roughly $92.28 million. Bitwise’s BITB also saw positive movement with about $14.62 million in inflows.
However, not every fund saw gains. Grayscale’s GBTC recorded an outflow of about $18.40 million, while VanEck’s HODL also saw money leave the fund. Still, the overall market result remained strongly positive.
The latest Bitcoin ETFs inflows suggest that large investors may be returning to Bitcoin exposure through regulated products. Spot ETFs make it easier for institutions, advisors, and traditional investors to gain Bitcoin exposure without directly holding BTC.
For Bitcoin’s market, steady ETF buying can be important because it shows demand beyond crypto-native traders. While daily flows can change quickly, several days of positive inflows often improve market sentiment.
The return of strong buying from BlackRock and other major issuers may also support the view that Bitcoin remains a key asset for investors looking at long-term digital asset exposure.
