Were Tamil Nadu 2026 exit polls accurate?

Which exit poll was most accurate for TN 2026?

Accuracy varies by methodology — sample size, geographic spread, and weighting model all affect outcomes. The exit poll accuracy page on Greatidude tracks each agency's projected range vs. actual seat count for DMK, TVK, ADMK, and others.

Why do exit polls differ from official results?

Late-breaking voter movement, last-day turnout composition, model weighting of castes/regions, and sampling bias in booth selection all contribute to divergence. In TN 2026, the three-way contest between DMK, TVK, and ADMK added complexity to pollster models.

What should I trust more: exit poll or official result?

Always prioritize official constituency-level counted results published by the Election Commission of India. Exit polls are pre-result directional indicators — useful for anticipating trends but not a substitute for counted votes.

Why exit poll accuracy matters in 2026

TN 2026 was the first election featuring TVK as a major third party — most exit poll models were calibrated on two-party DMK vs ADMK contests
Urban constituencies (especially Chennai) showed high TVK turnout that many pollsters underweighted
Alliance arithmetic (smaller parties joining DMK or TVK fronts) created seat-level complexity beyond raw vote share
