Sidus Space Inc is trading at $4.66 (+6.15%) in after-hours trading, extending a rally driven by its upcoming addition to several major benchmarks.
- The company is set to join the Russell 3000, Russell 2000, and Russell Microcap indexes, with inclusion becoming effective after the market close on June 26, 2026.
- This index-inclusion catalyst has served as the primary driver for the stock, while broader strength in U.S. equities on June 11 provided additional support for investor sentiment.
