Grayscale Solana ETF (NYSE: GSOL) index shifts key trading venues

Rhea-AI Filing Summary

Grayscale Solana Staking ETF reported that CoinDesk Indices, Inc., the Index Provider for the fund, has updated the trading platforms used to calculate its underlying CoinDesk Solana Benchmark Rate.

Effective January 20, 2026, the Index Provider added Binance and Gate for SOL-USDC trading pairs and HashKey for the SOL-USD trading pair, after those venues met its inclusion conditions. At the same time, it removed Bitfinex’s SOL-USD trading pair because that platform no longer met those conditions in a scheduled monthly review.

Following these changes, the Index now uses several exchanges for SOL-USD pairs, including Bitstamp by Robinhood, Bullish, Crypto.com, Gemini, HashKey, Kraken, LMAX Digital, and OKX, and for SOL-USDC pairs, including Binance, Bitstamp, Bullish, Bybit, Gate, Kraken, and OKX. The Index Provider states it may further adjust venues or methodology over time.
