Nike Exits S&P 100 After 18 Years Amid Market Cap Decline

Nike, the prominent sportswear company, is set to be removed from the S&P 100 index on September 21, marking its departure from the benchmark after approximately 18 years. This exit follows a substantial decline in the company's market capitalization, which has fallen by nearly 80% from its all-time high in November 2021. At its peak in November 2021, Nike's market value reached $264 billion, with shares trading at $179.10. Currently, the company's valuation stands at approximately $57 billion, representing a 78% decrease, and its shares are trading around $38 each. The company experienced a 36% drop in market cap in 2026 alone, contributing to its eventual removal from the S&P 100. The reshuffling of the S&P 100 index is governed by rules set by S&P Dow Jones Indices, which aim to ensure the indexes remain representative of their respective market capitalization ranges through quarterly adjustments. Despite its removal from the S&P 100, Nike will continue to be listed in the broader S&P 500 index. This multiyear decline for Nike has led to its exit from the top 100 U.S. companies by market cap. The trend indicated by this change shows a shift in the composition of the blue-chip index, with information technology sector companies like Dell Technologies, Palo Alto Networks, Arista Networks, and Sandisk poised to take the places of departing companies. This influx of tech companies suggests a growing emphasis on servers and data infrastructure within the index. The reasons behind Nike's decline are attributed to a deterioration in its underlying business, as indicated in Nike's investor reports. While specific details of the business deterioration were not fully elaborated in the provided text, the sustained drop in market value points to significant challenges faced by the athletic apparel giant. Other companies also exiting the S&P 100 on the same date include Honeywell Aerospace, Simon Property Group, and Colgate-Palmolive, further underscoring the dynamic nature of index composition and the factors influencing corporate valuations. The S&P 100, also known as the "Top 100" index, comprises the 100 largest U.S. companies by market capitalization that are listed on the S&P 500. Its inclusion signifies a company's status as a major player in the U.S. equity market. Nike's nearly two-decade tenure in this index highlights its historical significance and market dominance.
