The New Hampshire Senate saw the election of the first-ever female majority. This is the first time this has occurred in any chamber of any state legislature in United States history.[2] In New York, the Democrats obtained a trifecta for the first time since 1935, and in Delaware for the first time since 1977.[3]
The Democrats took control of six legislative bodies to the Republicans' four. Democrats took control of the Delaware House of Representatives, for the first time since 1985, the Montana House of Representatives, the Nevada Senate, and the New York State Senate, for the first time since 1966, the Ohio House of Representatives, and the Wisconsin State Assembly. Republicans took control of the Montana Senate; both houses of the Tennessee General Assembly,[4] for the first time since 1870; and the Oklahoma Senate, for the first time in state history. With the Montana Senate and the Montana House of Representatives flipping, this election cycle marked the last time in U.S. history as of 2024 where the upper house and lower house held by different political parties in a state legislature both flipped in the same cycle.
Summary table
Regularly-scheduled elections were held in 85 of the 99 state legislative chambers in the United States. Nationwide, regularly-scheduled elections were held for 5,948 of the 7,383 legislative seats. Many legislative chambers held elections for all seats, but some legislative chambers that use staggered elections held elections for only a portion of the total seats in the chamber.[5] The chambers not up for election either hold regularly-scheduled elections in odd-numbered years, or have four-year terms and hold all regularly-scheduled elections in presidential midterm election years.
Note that this table only covers regularly-scheduled elections; additional special elections took place concurrently with these regularly-scheduled elections.

Notes
^ abFollowing the defection of Senator Micheal R. Williams from the Republican party, no party controlled the Tennessee Senate. Thus the chamber is not included in the total here.
^ abThe Alaska Senate was controlled by a coalition of Democrats and Republicans. The minority caucus consists of Republicans who were not part of the majority coalition.
^ abcdefghThe upper houses of Arkansas, Delaware, Florida, Hawaii, Illinois, Minnesota, New Jersey, and Texas use a 2-4-4 term length system.
^ abcThese figures represent the seats of Nebraska's unicameral legislature.
^The Oklahoma Senate were evenly split between Democrats and Republicans, but the Democratic Party controlled the chamber by virtue of holding the governor's office.
^The Montana House of Representatives were evenly split between Democrats and Republicans, but the Democratic Party controlled the chamber by virtue of holding the governor's office.
