MSCI has made a significant decision to retain crypto-treasury companies (those holding 50% or more assets in cryptocurrency) within its Global Investable Market Indexes through the February 2026 review cycle. This move effectively prevents potential passive fund outflows estimated at up to $15 billion, providing crucial stability for institutional-grade crypto firms. The news triggered immediate positive sentiment in after-hours trading, with MicroStrategy shares gaining momentum. The policy decision signals growing institutional acceptance and mainstream integration of cryptocurrencies at the index level, reshaping how traditional investment benchmarks treat digital asset holdings.
