MSCI's Evolving Role from Benchmark Provider to Market Regulator

MSCI has transitioned from a passive index provider to a de facto market regulator due to the massive scale of passive capital tracking its benchmarks. The firm's recent consultation, launched on August 3, 2026, proposes redefining eligibility for "non-operating companies," a move that could exclude major corporate Bitcoin holders like MicroStrategy from global indexes. This shift raises concerns regarding the power of private index providers to influence corporate governance and capital access.
