Hang Seng indexes add SpaceX after June 12, 2026 listing

Hang Seng Indexes will add newly listed SpaceX to the Hang Seng Hong Kong and US Technology Index’s designated U.S. constituent list and rebalance the eight U.S.-listed members to equal weight.

Fact Check
The official Hang Seng Indexes Company notice (hsi.com.hk PDF) directly confirms every element of the claim: SpaceX's June 12, 2026 listing, its addition to the designated U.S.-listed constituent list (previously the seven 'Magnificent 7' stocks, now 8), and the recalculation of the 8 U.S. constituents to equal weight (after June 23 close, effective June 29). This is corroborated by The Standard, AAStocks, Odaily, and BlockBeats.
