CME Group and CF Benchmarks launched the CME CF Crypto Market Index and CME CF Emerging Crypto Index on August 31, 2026, shortly after 10 a.m. London time. Both use free-float market capitalization, update every second around the clock and undergo reviews in June and December. The Emerging Crypto Index excludes Bitcoin and Ether and tracks BNB, XRP, Solana, Hyperliquid, Chainlink, Stellar Lumens, Sui, Uniswap, Avalanche and Aave. The companion Crypto Market Index contains those 10 assets plus Bitcoin and Ether. Daily settlement versions are published at 4 p.m. in London, New York and Singapore/Hong Kong. The indexes are available for licensing to financial products, investment funds and derivatives, expanding CME's multi-asset crypto infrastructure. Their methodology includes custody and protocol-use requirements, excludes meme coins and sets a combined 10% initial weight limit for assets temporarily admitted under a new-eligibility provision.
