Exit polls for the 2026 West Bengal Assembly election show divided projections between the Trinamool Congress (TMC) and the Bharatiya Janata Party (BJP).

The results are critical as they determine whether Mamata Banerjee (TMC) can maintain her party's 15-year hold on the state or if the BJP can finally break that dominance.

Data from eight different exit polls released in April 2026 present conflicting narratives. Six of those eight surveys predict that the BJP could end the TMC's long-term rule [2]. Other polls, however, forecast a fourth consecutive term for the TMC, suggesting the party retains its grip on the electorate [2].

The BJP has focused its campaign on promising an inclusive governance model for the region. Uttar Pradesh Chief Minister Yogi Adityanath (BJP) supported these efforts, and said voters should choose the BJP to establish an inclusive regime in West Bengal [1]. These efforts are part of a broader strategy to challenge the TMC's established political infrastructure.

BJP leaders said the TMC has practiced appeasement politics to maintain power [1]. This rhetoric serves as the primary counter-narrative to the TMC's platform of continued stability, and regional leadership [2].

The stakes remain high given the scale of previous victories. In the 2021 West Bengal Assembly election, the TMC won 215 out of 294 seats [1]. A significant shift in voter sentiment would be required for the BJP to overturn such a substantial previous majority.

While the exit polls provide a glimpse into potential outcomes, the official results are expected shortly. The divergence in the polling data highlights a deeply polarized political landscape in the state, one where neither side has a definitive, undisputed lead in the projections.

The discrepancy between exit polls indicates a highly competitive environment where traditional polling metrics may struggle to capture the exact shift in voter sentiment. If the BJP succeeds, it marks a historic collapse of the TMC's regional hegemony. Conversely, a TMC victory would solidify Mamata Banerjee's position as a primary obstacle to the BJP's expansion in Eastern India.
