Nike is leaving the S&P 100 on Sept. 21 after 18 years, the latest marker of a decline that has erased roughly $200 billion in market value since its November 2021 peak. The sportswear giant will remain in the S&P 500, but its demotion from the large-cap benchmark underscores a collapse that has taken the company from a $264 billion valuation, shares at $179.10, to roughly $57 billion at $38 apiece, a 78 percent drop over five years. A 36 percent slide in 2026 alone sealed the exit.

The numbers behind the exit

The reshuffle follows S&P Dow Jones Indices rules that adjust quarterly to keep the index representative of its market-capitalization range. Nike’s removal coincides with the addition of four information-technology names: Dell Technologies, Palo Alto Networks, Arista Networks and Sandisk. Honeywell Aerospace, Simon Property Group and Colgate-Palmolive also depart on the same date. The turnover marks a continued shift toward server and data-infrastructure companies in the blue-chip gauge.

What drove the decline

Fiscal 2026 revenue fell 2 percent on a currency-neutral basis to $46.4 billion, and the company warned the decline would extend into the first half of fiscal 2027. Greater China remained a drag, with sales down 17 percent on a constant-currency basis in the quarter ended May 31, the eighth consecutive quarterly drop in the region. Direct-to-consumer revenue fell 6 percent to $17.7 billion, while wholesale revenue rose 6 percent to $27.5 billion, a mix shift the company has framed as intentional.

The turnaround narrative

Chief Executive Elliott Hill pointed to “meaningful structural improvements” under a strategy dubbed Sport Offense, citing progress in performance product and a focus on profitability over top-line growth. The company is also pulling online sales rights from major Chinese retail partners to take greater control of distribution, while facing domestic rivals Anta and Li Ning alongside international competitors Hoka and On. Reuters noted in June that shares were already down about 35 percent for the year at that point, reflecting skepticism that the turnaround would produce a meaningful recovery.

What to watch next

The S&P 100 exit is a symptom, not a cause. The next test is whether wholesale momentum and inventory discipline can stabilize revenue before the fiscal 2027 guidance window closes. If China’s eight-quarter slide extends, the index demotion may be the least of the valuation concerns.
