Spot Bitcoin ETFs maintained daily net inflows throughout the week. The highest daily figure for Bitcoin products came on June 9, with $386.27 million entering the sector.

The recent momentum underscores increasing demand from institutional and retail investors alike, particularly after the Securities and Exchange Commission (SEC) signaled openness to spot crypto funds beyond Bitcoin and Ethereum. Earlier, the SEC formally requested updated S-1 filings from prospective Solana ETF issuers—a sign that the regulated crypto ETF universe could soon expand further.
