CME Group began publishing two multi-asset cryptocurrency benchmarks on August 31, 2026: the CME CF Crypto Market Index and the CME CF Emerging Crypto Index. CF Benchmarks administers both indices, while CME distributes real-time readings roughly once per second and supplies daily London, New York and APAC reference values, including on weekends and bank holidays.
The Emerging Crypto Index excludes Bitcoin and Ether, but a CF Benchmarks research portfolio published on August 13 showed that removing the two largest tokens did not create broad diversification. The indicative weights were BNB 32.0%, XRP 27.6%, Solana 18.5% and HYPE 14.6%, leaving only 7.3% for all remaining assets. BNB and XRP alone accounted for 59.6% of the indicative allocation, while the four largest positions made up 92.7%.
CME stressed that neither benchmark currently settles a contract. No futures contract, ETF or fund accompanied the launch, and CME did not buy the underlying tokens. Publishing index prices therefore does not create automatic demand. A tradable product could use either benchmark later, but it would require a separate announcement. Formal reviews are scheduled for June and December, making December the first live test of how the benchmark responds to altcoin ranking changes.
The index launch also arrives as broader crypto commentary focuses on structural shifts beyond Bitcoin and Ether. VALR CMO Ben Caselin pointed to the Robinhood Chain, CeDeFi integrations such as VALR's link to Hyperliquid, and retail-driven tokenized ownership trends. Still, for CME's emerging benchmark, the immediate question is how much influence remains outside its four largest positions.
