The REX‑Osprey Solana Staking ETF (ticker SSK) launched on July 2, 2025, marking a milestone in crypto investing. Its debut day generated approximately $33 million in trading volume, placing it in the top 1% of ETF launches—an extraordinary performance for a new fund.

SSK also attracted $12 million in inflows on day one, a strong signal of investor enthusiasm.This mixed portfolio fund balances spot SOL exposure with staking yield, staking at least half its assets via Anchorage Digital for returns.

🚀 Outpacing Futures and Gaining Momentum

• According to Bloomberg analyst Eric Balchunas, SSK’s $33M trading volume surpassed the debut volumes of prior Solana and XRP futures ETFs, though still trailing far behind Bitcoin & ETH spot ETF launches.

• The fund recorded $8M in volume within the first 20 minutes—a “healthy start” highlighted by Bloomberg’s James Seyffart.

This robust opening indicates significant initial demand, possibly laying the groundwork for spot Solana ETF approval, which analysts estimate has a 95% chance before year-end.

📈 Impact on SOL and Institutional Activity

• On its debut, SOL price climbed around 5%, reaching approximately $155.

• Meanwhile, Solana CME futures open interest surged ~13%, hitting a record $167 million, reflecting growing institutional engagement.
