Hang Seng Indexes to add Anthropic to Hang Seng Hong Kong-US Tech Index

Index inclusion is a quiet but consequential signal: it pulls an AI developer into a benchmark that spans Hong Kong and US tech listings, widening the exposure of index-tracking products to the AI theme without any single-stock decision. The practical effect hinges on details Hang Seng Indexes has not disclosed — the effective date and the weighting — since those determine how much passive money actually moves. Whether the compiler follows with further specifics, and how the inclusion is timed relative to other index changes, is the open question worth watching.
