Solana's spot ETFs have reached a significant milestone, surpassing $1 billion in assets under management (AUM), driven by $35.17 million in inflows last week. This marks five consecutive positive sessions for the ETFs, highlighting growing institutional interest in Solana. Notably, Goldman Sachs holds a substantial $108 million position in Solana ETFs, signaling strong traditional finance support for the cryptocurrency. Data from Alphractal indicates a rising delta between whale and retail activity, suggesting that larger investors are increasingly active while retail participation remains subdued. Since February, Solana futures have been dominated by large whale orders, even as the price stabilized. This trend underscores the current institutional-first environment for Solana, with retail traders yet to significantly re-engage.
