Short answerTwo alliances fought the April 2026 election: the DMK-led alliance (Congress, DMDK, VCK, CPI, CPI(M), MDMK, IUML and others) and the AIADMK-led NDA (AIADMK, BJP, PMK, AMMK). TVK and NTK fought alone. After the result, Congress, VCK, CPI, CPI(M) and IUML backed the TVK government.
Checked 2 October 2026. Alliance members against the March 2026 reports named below; seats against ECI's results; positions after the result against the 13 May 2026 vote and the 21-22 May cabinet lists.
The DMK-led alliance
Before the vote it brought together the DMK, Congress, DMDK, VCK, CPI, CPI(M), MDMK, IUML and smaller parties. MDMK, KMDK and MMK were also allotted seats; ECI counts candidates who stood on the DMK's symbol under the DMK.

| PMK | 18 | 4 | Its four MLAs were reported neutral in the 13 May vote |
| AMMK | 11 | 1 | Its one MLA, expelled by the party on 12 May, voted for the government on 13 May |
Parties that fought alone
TVK contested 233 seats and won 108; NTK contested all 234 and won none. Neither was in an alliance. See who backs the TVK government and NTK.
“Seats contested” and “won” are ECI's figures (4 May 2026); they count an ally that stood on a bigger party's symbol under that party. The “after the result” column follows the confidence vote of 13 May 2026 and the cabinet lists of 21 and 22 May; the alliances themselves were not formally dissolved in anything we found, so read it as where each party stood on those dates.
