First-order effects

• Asset managers and institutional investors gain an S&P-branded benchmark they can license for passive crypto products, replacing the ad-hoc index constructions from CoinMarketCap and Bitwise that defined the category until now.
• Lukka converts its data operation into the official feed for one of finance's most recognizable index families, giving it a marquee reference client against other crypto data vendors.

Second-order effects

• Rival index publishers face pressure to field their own crypto benchmark families or cede licensing revenue on the products — ETFs, futures, structured notes — that track them, a contest CoinMarketCap's earlier terminal listings only previewed.
• The existence of a mainstream benchmark lowers the barrier for fund sponsors to package crypto exposure, the same product pathway later visible in Trump Media's agreement with Crypto.com to launch Truth.Fi digital-asset ETFs.

Third-order effects

• If incumbents keep absorbing crypto into standard market infrastructure — benchmarks, then exchange platforms like the London Stock Exchange's new blockchain-based system, then even official statistics as floated by the US Commerce Department — the 'crypto legitimacy gap' closes from the infrastructure side rather than through regulation alone.
• Index provision becomes a gatekeeping layer for digital assets: whoever defines the benchmark shapes which of the hundreds of tradable coins institutional capital can reach, concentrating pricing power in data vendors and index licensors.
