Despite recent public friction over power-sharing demands and seat allocations, the long-standing alliance between the Dravida Munnetra Kazhagam (DMK) and the Congress is expected to remain intact ahead of the 2026 Tamil Nadu Assembly elections. The Secular Progressive Alliance (SPA), led by the ruling DMK, continues to hold a strong position in pre-poll assessments, bolstered by its sweeping victory in the 2024 Lok Sabha polls where it secured all 39 seats in the state. Political observers note that ideological alignment and mutual electoral benefits make a breakup unlikely, even as tensions surface in negotiations.

The strain has primarily stemmed from Congress leaders, including MP Manickam Tagore and functionary Praveen Chakravarty, pushing for a greater role in governance—such as cabinet berths—and a larger share of Assembly seats beyond the 25 contested (and 18 won) in 2021. Chief Minister and DMK president M.K. Stalin has firmly rejected power-sharing, insisting the DMK will aim for a clear majority on its own and maintain allies as supportive partners rather than coalition co-rulers. AICC General Secretary KC Venugopal has signaled that coalition matters, including power-sharing, will feature in formal discussions, but both sides have worked to contain visible discord.

DMK MP Kanimozhi recently addressed media queries, affirming that the alliance has weathered ups and downs over decades with no prospect of change. She emphasized its enduring nature, dismissing speculation as opposition attempts to sow confusion. Political analyst Professor Ramu Manivannan observed that for ideological and strategic reasons, the Congress is likely to stay committed to the DMK, avoiding a move that could benefit rivals like the BJP-AIADMK combine. The alliance's cohesion is further reinforced by recent expansions, such as the Desiya Murpokku Dravida Kazhagam (DMDK) formally joining on February 19, which strengthens the bloc while complicating seat math for partners like Congress.

Seat-sharing talks among SPA constituents are set to begin on February 22, following the conclusion of the Tamil Nadu Assembly session. The DMK has formed a constituency committee for these negotiations, prompted partly by Congress nudges over perceived delays. While the Congress seeks enhanced representation to address cadre pressures and build its footprint in the state, the DMK's dominance—targeting over 170-200 seats—provides leverage to resist major concessions. Periodic criticisms from Congress quarters, including references to past issues like the 2G spectrum case, have irked DMK leaders, who have sought disciplinary action against vocal detractors before advancing talks.

As elections approach, the alliance's stability appears resilient, rooted in shared anti-BJP positioning and historical cooperation since the 1970s. Experts view the current frictions as typical pre-poll bargaining rather than existential threats, with both parties prioritizing a united front to counter opposition challenges. The outcome of upcoming negotiations will clarify specifics on seats and roles, but indications point to the DMK-Congress partnership holding firm to maintain its electoral edge in Tamil Nadu.
