Grayscale Bitcoin Mini Trust ETF to adopt CoinDesk Bitcoin Benchmark Rate for NAV effective April 1, 2026

Grayscale Bitcoin Mini Trust ETF

As of April 1, 2026, Trust will value Bitcoin holdings using the CoinDesk Bitcoin Benchmark Rate, replacing the CoinDesk Bitcoin Price Index (XBX).
The new index aggregates trade data from 11 licensed platforms including Binance, Kraken, Gemini, and Crypto.com.
If the benchmark is unavailable, the Sponsor uses a cascading fallback: Coin Metrics Secondary Index, then a principal market price, then a good-faith estimate.
The Sponsor believes the new methodology provides a more accurate picture of Bitcoin price movements and reduces impact of anomalous trading.
