Heading into the election, the incumbent is Cynthia Lummis (Republican), who was first elected in 2020.

A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. Wyoming utilizes a closed primary process.[1][2]

For information about which offices are nominated via primary election, see this article.

Thirty-three of the 100 U.S. Senate seats are up for election, and another two seats are up for special election. Democrats hold 13 of the seats up for election, and Republicans hold 22. As of January 2026, 11 members of the U.S. Senate announced they are not running for re-election. To read more about the U.S. Senate elections taking place this year, click here.

This is one of 10 open U.S. Senate races this year in which an incumbent is not running for re-election. Across the country, four Democrats and six Republicans are not running for re-election — more than any year since 2012. In 2024, eight incumbents — four Democrats, two Republicans, and two independents — did not seek re-election.
