Nike exits S&P 100 in 2026 rebalance, four tech firms take over slots

Nike is set to drop out of the S&P 100 before U.S. markets open on September 21, 2026, marking one of the more notable index shakeups of the year for a company that has long been a fixture among America’s largest publicly traded names. This Nike S&P 100 exit comes from S&P Dow Jones Indices as part of its regular quarterly rebalance, and it puts the sportswear giant in the same boat as three other well-known corporations losing their spot in the benchmark.

Key takeaways

• Nike will leave the S&P 100 before U.S. trading begins on September 21, 2026, following an announcement made September 4.
• Honeywell Aerospace, Simon Property Group, and Colgate-Palmolive are also exiting the index alongside Nike.
• Dell Technologies, Palo Alto Networks, Arista Networks, and SanDisk will take their place in the S&P 100.
• Nike remains part of the broader S&P 500 and continues trading normally on the stock market.
• The change reflects S&P Dow Jones Indices’ effort to keep the index representative of current market capitalization ranges.

Nike’s Departure from the S&P 100

Nike will officially leave the S&P 100 before the opening bell on September 21, 2026, according to S&P Dow Jones Indices. The index provider confirmed the change on September 4, framing it as a routine part of its quarterly rebalance rather than a reaction to any single event tied to the company.

Nike isn’t leaving alone. The sportswear brand joins Honeywell Aerospace, Simon Property Group, and Colgate-Palmolive among the companies dropping out of the S&P 100 in this cycle. Losing a spot in the index doesn’t happen in isolation — it typically signals that a company’s relative market capitalization has shifted compared to peers still climbing the ranks.

Why this matters for index composition

Being removed from a major benchmark like the S&P 100 doesn’t reflect a company’s operational health directly, but it does say something about how Wall Street currently sizes up its market value relative to other large-cap names. When four companies exit at once, it usually means the index provider is recalibrating to keep pace with which firms actually belong among the top 100 by size and sector representation.

New Additions and Index Rebalance Purpose

Filling the four vacated slots are Dell Technologies, Palo Alto Networks, Arista Networks, and SanDisk — all companies with strong ties to the technology and cybersecurity sectors that have been expanding their market footprint. Their inclusion tilts the S&P 100’s composition further toward tech-driven names, a pattern that has become increasingly common in recent rebalances across major U.S. indices.

The S&P 100 tracks 100 large U.S. companies spanning multiple sectors and functions as a subset of the broader S&P 500. According to S&P Dow Jones Indices, the goal of this quarterly rebalance is to keep the index accurately representative across different market-capitalization ranges — in other words, to make sure the companies inside it still reflect where real market value sits today.

This is a mechanical, scheduled process rather than a punitive one. Every quarter, S&P Dow Jones Indices reviews its indices and swaps out companies whose market cap or sector weighting no longer fits the benchmark’s criteria, replacing them with firms that better match current market conditions.

Impact on Nike and Market Trading

Here’s the detail that matters most for investors: Nike’s removal from the S&P 100 has no bearing on its shares trading on the open market. The company remains listed in the broader S&P 500 index, and nothing about this announcement suggests a halt or disruption to how Nike stock is bought and sold.

The S&P Dow Jones Indices announcement makes no mention of Nike being dropped from the S&P 500 — only from the narrower 100-company benchmark. That distinction is worth underlining because index exits can sometimes get misread as a sign of trouble. In this case, it’s strictly a change to index composition, not a statement about Nike’s standing as a publicly traded company or its day-to-day market activity.

For everyday investors, the practical takeaway is straightforward: funds and portfolios tracking the S&P 100 will adjust their holdings to reflect the swap, dropping Nike, Honeywell Aerospace, Simon Property Group, and Colgate-Palmolive while adding Dell Technologies, Palo Alto Networks, Arista Networks, and SanDisk. Anyone holding Nike shares directly, or through funds tied to the S&P 500 rather than the S&P 100, sees no direct change from this particular rebalance.
