What happened
Nike will exit the S&P 100 on Sept. 21 after losing ~$200B in market cap since its Nov. 2021 peak of $264B, now worth roughly $57B with shares trading around $38. IT sector companies Dell Technologies, Palo Alto Networks, and Arista Networks are replacing Nike and other departing companies in the benchmark.
Why it matters
Minimal practical impact for builders. The only notable signal is the index reshuffling replacing traditional retail with IT sector companies, but this is a passive index mechanics story, not something that changes what developers or founders should build, buy, or decide.
Discussion angle
The quiet signal here is S&P index composition shifting from legacy retail/industrial toward IT security and networking—worth a 30-second mention as a macro backdrop, but not worth deep discussion.
