Key Highlights

  • Okta (NASDAQ:OKTA) will join the S&P 500 before the open on Wednesday, November 4, 2026, replacing Kenvue, according to an S&P Dow Jones Indices announcement made on October 30.
  • Kenvue (NYSE:KVUE) is being removed because Kimberly-Clark, itself an S&P 500 member, is acquiring it, and the deal is expected to complete soon, pending final closing conditions.
  • Okta (NASDAQ:OKTA) leaves the S&P MidCap 400 after about 18 months there, having joined that index effective May 1, 2025, and it is classified in the Information Technology sector.
  • Glaukos (NYSE:GKOS) moves into the MidCap 400 to replace Okta, and McGrath RentCorp and Loar Holdings enter the SmallCap 600 as part of the same announcement.

The Announced Changes

S&P Dow Jones Indices said on October 30, 2026 that Okta (NASDAQ:OKTA) will replace Kenvue in the S&P 500 effective before the open on November 4. The release describes a chain of moves. Glaukos (NYSE:GKOS) takes Okta's place in the MidCap 400, which is the usual step for a company that moves up. McGrath RentCorp (NASDAQ:MGRC) takes Glaukos's place in the SmallCap 600. A second SmallCap 600 change replaces LiveRamp, which Publicis Groupe is acquiring, with Loar Holdings (NYSE:LOAR). The release gives no separate reason for Okta, Glaukos and McGrath, and says the Kenvue and LiveRamp deals are expected to close soon, pending final conditions.

How Index Inclusion Works

The S&P 500 is a market-cap weighted index, and funds that track it must hold each member in proportion. When a company joins, those funds buy its shares and sell others to fund the purchase, usually at the close on the last trading day before the change. That Demand can lift a stock before the effective date, though the effect varies and often fades. No estimate of the resulting flows was published for Okta (NASDAQ:OKTA), so none is given here. Funds such as SPDR S&P 500 ETF Trust (NYSEARCA:SPY) must adjust holdings to match the new weights. A stock moving up from the MidCap 400 also leaves behind funds that track that smaller index.

Risks and What to Watch

Inclusion does not change a company's Earnings or cash flow, so any price gain tied to the event may be temporary. Okta (NASDAQ:OKTA) remains exposed to demand for identity and security software, competition from larger platforms and the technology sell-off that hit the Nasdaq Composite on October 30. Okta last reported its fiscal third quarter in early December 2025, so its next report is likely a month away, though no date was confirmed here. Watch the S&P Dow Jones Indices notice for any change in timing, since index announcements can be amended if a deal closes earlier or later than expected, the Kimberly-Clark and Kenvue closing, and the November 3 midterm elections and November 6 jobs report for market tone.

Where Things Stand

Okta (NASDAQ:OKTA) is the identity security company set to join the S&P 500 before the open on November 4, 2026, and Kenvue is the member being removed after its Acquisition by Kimberly-Clark. The balance of evidence shows an index change driven by a corporate deal and a promotion, not by new financial results. Index Funds will need to buy Okta (NASDAQ:OKTA) and sell other holdings, but the effect on its shares is uncertain. The next catalysts are the effective date itself and the Kenvue closing.
