alt Hacker NewsI'm not debating any of that. This discussion is about the S&P500 as a benchmark, which has an expressly stated purpose of tracking large-cap US equities.
This discussion is about if S&P500 actually achieves this benchmark, when it has (antiquated) rules that exclude large-cap US companies of the likes of SpaceX, Anthropic, and OpenAI.
Benchmarks are governed (to some extent) by natural selection. If the S&P criteria prove obsolete, then it will be replaced by other indices that use your proposed criteria. Everything's going to be just fine.
