U.S. spot Solana ETFs recorded $86.6 million in net inflows on Friday, September 25, their largest daily intake since launch, lifting weekly inflows to $188.2 million. Bitwise's BSOL attracted about $128 million during the five trading sessions and accounted for roughly three quarters of the group's cumulative $1.6 billion in net inflows. The inflows coincided with SOL trading above $119, a 14% monthly gain, the launch of Solana's Alpenglow consensus upgrade on devnet, and further SOL purchases or acquisition plans by DeFi Development Corp. and Forward Industries. U.S. spot Bitcoin ETFs also took in about $2.4 billion during the week, reflecting stronger demand for regulated crypto investment products.
