Grayscale Solana Staking ETF Updates Index Trading Venues

What Happened

• Grayscale Solana Staking ETF (GSOL) filed an 8‑K on January 26, 2026 reporting that CoinDesk Indices, Inc. updated the trading venues used to calculate the CoinDesk Solana Benchmark Rate. Effective January 20, 2026, CoinDesk added Binance (SOL‑USDC), Gate (SOL‑USDC) and HashKey (SOL‑USD) and removed Bitfinex (SOL‑USD) after its monthly review.

Key Details

• Effective date of change: January 20, 2026; 8‑K filed January 26, 2026 and signed by Edward McGee (CFO).
• Added trading pairs: Binance (SOL‑USDC), Gate (SOL‑USDC), HashKey (SOL‑USD).
• Removed trading pair: Bitfinex (SOL‑USD).
• Constituent platforms used in the Index Price as of the filing:
  • SOL‑USD: Bitstamp by Robinhood, Bullish, Crypto.com, Gemini, HashKey, Kraken, LMAX Digital, OKX.
  • SOL‑USDC: Binance, Bitstamp, Bullish, Bybit, Gate, Kraken, OKX.
• CoinDesk may continue to add or remove venues during scheduled monthly reviews per the Trust’s S‑1 disclosure.

Why It Matters

• The ETF tracks an index price (CoinDesk Solana Benchmark Rate); changes in the venues used to calculate that index can affect the index inputs (price sources, liquidity and spreads) and therefore may influence how closely the ETF tracks Solana market prices.
• This filing is informational — it reports an index-methodology change by the index provider rather than any change to the ETF’s investment strategy or fees. Investors who track GSOL’s performance or monitor index composition should note the updated list of trading venues.
