Who won the 2026 Tamil Nadu assembly election?

No party won a majority. Actor Vijay's Tamilaga Vettri Kazhagam (TVK) finished as the single largest party with 108 of 234 seats and a 34.92% vote share. The DMK fell to 59 seats and the AIADMK to 47. TVK then formed a coalition government and Vijay was sworn in as Chief Minister on 10 May 2026.

Did M.K. Stalin lose the election?

Yes. The DMK was reduced to 59 seats, and Chief Minister M.K. Stalin lost his own Kolathur constituency, which he had won three times before. He resigned as Chief Minister on 5 May 2026.

Who is Vijay and what is TVK?

C. Joseph Vijay is one of Tamil cinema's biggest stars. He founded the Tamilaga Vettri Kazhagam (TVK) and entered electoral politics, and in its first full assembly contest the party became the largest in the house, winning both Perambur and Tiruchirappalli East for Vijay himself.

How did TVK form a government without a majority?

It was a hung assembly, with 118 seats needed for a majority. TVK, on 108 seats, formed a coalition that included a Congress defection from the rival Secular Progressive Alliance, with four other parties offering external support. The government passed a floor test on 13 May 2026.

Vijay's Earthquake: How TVK Broke the Dravidian Duopoly in Tamil Nadu, Explained

For nearly six decades, Tamil Nadu offered voters a simple choice between two Dravidian parties: the DMK or the AIADMK. On 4 May 2026, the state tore up that script. A party that did not exist three years ago, led by one of the biggest movie stars in the country, finished first. The sitting chief minister lost his own seat. And Tamil Nadu woke up to something it had not seen since the 1960s: a non-Dravidian party at the top of the table.

This is how Vijay and the Tamilaga Vettri Kazhagam rewrote Tamil politics.

The 60-second version

What: TVK, the party founded by actor Vijay, won 108 of 234 seats, finishing as the single largest party with a 34.92% vote share.
The collapse: The DMK fell to 59 seats and the AIADMK to 47.
The shock: Chief Minister M.K. Stalin lost his own seat, Kolathur, and resigned.
The outcome: A hung assembly. TVK stitched together a coalition, and Vijay was sworn in as chief minister on 10 May 2026.
Why it is historic: It is the first time since the 1960s that a non-Dravidian party has been the largest in the Tamil Nadu assembly.

Who's who

C. Joseph Vijay is a top-tier Tamil film star who turned his enormous fan network into a political machine, founding the Tamilaga Vettri Kazhagam (TVK). In the party's first full assembly contest, he won both Perambur and Tiruchirappalli East and became chief minister.

M.K. Stalin, son of the late DMK patriarch M. Karunanidhi, led the DMK to power in 2021. In 2026 he lost both his government and his Kolathur seat, a constituency he had won three times running.

Edappadi K. Palaniswami (EPS) led the AIADMK, which finished third with 47 seats. He retained his Edappadi seat with one of the widest margins in the state, keeping the AIADMK alive as a force even in defeat.

The numbers behind the upset

The vote shares show a genuine three-way fracture, not a simple two-party swing.

TVK: 108 seats, 34.92% (about 1.72 crore votes).
DMK: 59 seats, 24.19% (about 1.19 crore votes).
AIADMK: 47 seats, 21.21% (about 1.05 crore votes).
Congress: 5 seats.
BJP: 1 seat.
Majority mark: 118, which no single party reached.

Turnout hit 85.1%, the highest in the state's history. A new entrant taking nearly 35% of the vote in its first real outing is the kind of number that does not just win an election; it resets a party system.

How it happened: the timeline

2021: The DMK wins power under M.K. Stalin, ending a decade of AIADMK rule.
2024 to 2025: Vijay formally launches TVK and builds it on his fan associations, touring the state and drawing huge crowds.
23 April 2026: Tamil Nadu votes in a single phase. Turnout reaches a record 85.1%.
4 May 2026: Results. TVK finishes first with 108 seats. The DMK is reduced to 59, the AIADMK to 47. The assembly is hung.
5 May 2026: M.K. Stalin resigns as chief minister after losing Kolathur.
10 May 2026: Vijay is sworn in as chief minister at the head of a coalition.
13 May 2026: The new government passes its floor test, with a Congress defection from the rival alliance and external support from four other parties.

Why the DMK lost

A 35% debut for a newcomer means votes came from everywhere, but a few currents stand out.

A new vehicle for anti-incumbency. Discontent with the DMK that might once have flowed to the AIADMK instead found a fresh, untainted home in TVK. Vijay was neither Dravidian incumbent nor old-guard rival.

Star power as organisation. Tamil Nadu has a long history of cinema shaping politics, from MGR to Jayalalithaa. Vijay converted a fan network that already blanketed every district into polling-booth muscle almost overnight.

A fractured opposition to the DMK. With the AIADMK weakened and the anti-DMK vote looking for a champion, TVK consolidated a large slice of it while the established parties split the rest.

What each side says

TVK and Vijay present the result as a generational verdict: a young electorate rejecting both old Dravidian formations in favour of a clean start, and a mandate to govern differently.

The DMK frames its defeat as the fragmentation of the anti-AIADMK vote by a celebrity insurgent, and argues that its welfare record remains popular even if its government fell. It now leads the opposition.

The AIADMK, having finished third, claims it remains the durable alternative and that TVK's coalition is inherently unstable, betting that a hung house will not last a full term.

The consequences: what's at stake

For Tamil Nadu. A first-time chief minister leads a coalition government in a state used to single-party Dravidian majorities. Governing a hung assembly, with allies who can withdraw support, is a far harder task than winning the election was.

For Dravidian politics. The DMK-AIADMK duopoly that defined Tamil Nadu since 1967 has been broken for the first time. Whether this is a one-off or a lasting realignment is the central question of the next five years.

For the celebrity-politics model. Vijay's success will be studied by every film star and influencer with political ambitions in India. If TVK governs well, the template spreads; if it stumbles, it becomes a cautionary tale.

For national politics. Tamil Nadu's 39 Lok Sabha seats were a reliable bloc for the DMK-led front. A new, untested ruling party in Chennai scrambles the calculations of every national alliance.

What to watch next

Coalition stability. With 108 of 118 needed, TVK depends on allies and defectors. Every floor test and budget vote becomes a stress test.
Governance versus stardom. Can a movie star run a complex state administration? The first hundred days will set expectations.
The DMK's response. Does it rebuild around a younger leader, or wait for the coalition to crack?
The AIADMK's relevance. Squeezed into third, it must decide whether to fight TVK for the anti-DMK space or rethink its strategy entirely.

Tamil Nadu has done something it has not done in 59 years. Whether Vijay's victory becomes a footnote or the start of a new era depends now on the far less glamorous work of governing, and Tamil Nadu will be watching every step.
