Cathie Wood's Ark Invest has gained its first exposure to Solana by purchasing nearly 500,000 shares of the 3iQ Solana Staking ETF (SOLQ) through two of its funds, ARK Next Generation Internet ETF (ARKW) and ARK Fintech Innovation ETF (ARKF). This move highlights Solana's growing importance in the crypto market and marks Ark Invest as the first U.S.-based ETF to invest in Solana. The 3iQ $SOL ETF was recently approved by Canadian regulators and launched on April 16, aligning with mainstream adoption of crypto ETFs. Beyond Ark Invest, other traditional financial firms like Charles Schwab are planning to enter the crypto space, signaling broader acceptance. Regulatory improvements under the current U.S. administration have facilitated this trend, with spot Bitcoin and Ethereum ETFs already approved in 2024. Despite some skepticism and challenges like custody, the SEC is expected to approve more crypto ETFs, including those for Solana and other altcoins, by the end of the year.
