Hang Seng Indexes Company confirmed that Space Exploration Technologies Corp. will join the Hang Seng HK-US Tech Index following its public listing on June 12, 2026. This strategic addition expands the index’s US-listed roster from seven to eight companies, evolving the grouping informally known as the Magnificent 7 into the M7+1.
SpaceX begins trading under the ticker SPCX.US on June 12. Adjusted weightings among US constituents will be calculated after the company completes its seventh trading day, projected for June 20. These new equal weights officially take effect on June 29, ensuring all eight US names carry identical representation within the benchmark.
This equal-weighting approach distinguishes the index from traditional market-cap benchmarks where giants dominate performance. By assigning equal seats at the table, SpaceX receives the same structural influence as established leaders like Amazon, Apple, and Nvidia immediately upon inclusion.
For passive funds tracking this widely watched cross-border benchmark, the addition creates mandatory buying demand that may support SpaceX during its early public trading days. However, existing investors face a dilution of exposure as allocations shift from a seven-way to an eight-way split when rebalancing takes effect later in June.
