Corteva to Exit the S&P 500 After Vylor Spin-Off, Moving to the S&P MidCap 400 on Oct. 6

Index reshuffle makes CTVA a mid-cap benchmark name starting Oct. 6

S&P Dow Jones Indices announced that Vylor Inc. (VYLR) was added to the S&P 500 on Oct. 1, 2026 after it was spun off from Corteva Inc. (CTVA) in a transaction completed that date. With Vylor replacing Corteva in the S&P 500, Corteva is set to leave the large-cap index and join the S&P MidCap 400 effective prior to the open on Tuesday, Oct. 6, 2026.

During market hours as of 11:01 AM, CTVA traded at $12.94, up $0.37.

The press release ties CTVA’s index move directly to the Vylor spin-off

According to S&P Dow Jones Indices, the catalyst for Corteva’s removal from the S&P 500 is structural rather than performance-driven: Vylor was added to the S&P 500 on Oct. 1 when Corteva spun off Vylor. In the same set of changes, S&P noted that “post spin-off, Corteva will be more representative of the mid-cap market space,” aligning with its move into the S&P MidCap 400.

CTVA’s shift from S&P 500 to S&P MidCap 400 is scheduled for the Oct. 6 open

S&P Dow Jones Indices summarized the upcoming effective changes prior to the opening bell on Oct. 6, 2026. For Corteva specifically, the change is a deletion from the S&P 500 and an addition to the S&P MidCap 400, with the company remaining classified in the Materials sector in both index listings.

Other index replacements provide context: CTVA’s move is part of a broader reconstitution

The same announcement included multiple index changes across the S&P 500, S&P MidCap 400, and S&P SmallCap 600, including Twilio’s planned move into the S&P 500 and a sequence of replacements involving Warner Bros. Discovery, Formfactor, Workiva, Olin, and Qorvo. S&P also cited pending deals as drivers for other changes, including Skyworks Solutions acquiring Qorvo and Paramount Skydance acquiring Warner Bros. Discovery.
