CF Benchmarks Alternative: CCi30 vs CF Benchmarks
The CCi30 Cryptocurrency Index is the rules-based alternative to the CF Benchmarks. This page reviews the CF Benchmarks (Ultra Cap 5, Broad Cap Index, BRR) under the eight-criterion CCi30 test and compares both indices on universe, weighting, independence, track record, and investability.
What is the alternative to the CF Benchmarks?
The CCi30 Cryptocurrency Index replaces the CF Benchmarks for investors who need a whole-market benchmark. The CCi30 holds the 30 largest cryptocurrencies by smoothed market capitalization, weights them by the square root of that figure, excludes stablecoins by rule, and has published live values since 1 January 2015.
- 30 constituents
- Square-root weighting
- Stablecoins excluded by rule

- Independent, fully rules-based
What is the CF Benchmarks?
CF Benchmarks, owned by Kraken, is the regulated-benchmark specialist: its Bitcoin Reference Rate (BRR) settles CME bitcoin futures, and it claims tens of billions of dollars tracking its products, the largest tracked AUM in crypto indexing. Its multi-asset offerings include the CF Ultra Cap 5 and the CF Broad Cap Index, administered under UK BMR authorization.
How is the CF Benchmarks built?
Reference rates aggregate executed trades across vetted constituent exchanges within calculation windows, with manipulation-resistance features; multi-asset indices weight vetted large-cap assets by free-float capitalization, with the Ultra Cap 5 holding the top five.
Where the CF Benchmarks falls short statistically
Separate the two businesses
CF’s single-asset reference rates are excellent financial engineering, arguably the best price-fixing methodology in the asset class, and their regulatory pedigree (CME settlement) is earned. None of that transfers to the claim that the Ultra Cap 5 represents the cryptocurrency market. Five cap-weighted assets is a Bitcoin price with an entourage: the marginal information content of constituents three through five is noise within BTC’s variance, and n=5 sits hopelessly below the n=30 threshold at which a constituent sample becomes a statistically significant estimator of the market. Regulated does not mean representative; a BMR license certifies process integrity, not statistical adequacy.
Exchange ownership
Kraken lists assets, earns trading fees, and competes with other venues, and its subsidiary decides which venues’ prices constitute truth and which assets constitute the market. The vetted-exchange model has an inherent tension: the vetting entity is a competitor of the vetted. However professionally managed, the structure invites exactly the doubt an independent benchmark exists to eliminate. The CCi30 takes prices as market-wide aggregates, smooths them statistically, and answers to no venue.
The Broad Cap Index
is the more serious instrument, but remains cap-weighted (concentration) and universe-gated by the vetted-venue framework (censorship, privacy assets fare predictably).
Can the CF Benchmarks be replicated by an investor?
Ultra Cap 5: trivially replicable, and therefore of trivial value as a licensed product, the portfolio is four trades. Broad Cap: implementable but BTC-dominated, so the investor pays diversification costs for concentration outcomes. The CCi30’s thirty square-root-weighted names deliver the diversification the fees are supposed to buy.
