Nagaon Lok Sabha bypoll result prediction 2026: Assam’s Nagaon parliamentary constituency votes on October 6, with counting scheduled for October 9. BJP, Congress and AIUDF are the main forces in the contest. This is a pre-poll editorial forecast based on the 2024 Lok Sabha baseline and the latest 2026 campaign dynamics, not an exit poll.
Why the Nagaon bypoll is important
The seat fell vacant after Pradyut Bordoloi left the Lok Sabha seat following his move into state politics. The 2026 bypoll brings a fresh three-way contest between BJP’s former IAS officer Debashish Sharma, Congress’s former Batadroba MLA Sibamoni Bora and AIUDF chief Badruddin Ajmal.
Key candidates
| Candidate | Party | Profile |
|---|---|---|
| Debashish Sharma | BJP | Former IAS officer and former Nagaon Deputy Commissioner |
| Sibamoni Bora | Congress | Former Batadroba MLA |
| Badruddin Ajmal | AIUDF | AIUDF chief and established regional leader |
2024 Lok Sabha baseline
In 2024, Congress’s Pradyut Bordoloi won Nagaon with 788,850 votes, around 50.9%. BJP’s Suresh Borah polled 576,619 votes, about 37.2%, while AIUDF’s Aminul Islam received 137,340 votes, about 8.9%.
Our result prediction
Predicted winner: Debashish Sharma — BJP.
Confidence: Low to moderate. The forecast is not based on a claim that the BJP will automatically inherit the entire 2024 opposition vote. Instead, the BJP enters the bypoll with the advantage of being the state ruling party, a candidate who previously served as Nagaon’s Deputy Commissioner and a stronger statewide organisation after the 2026 Assembly election.
Why BJP has an edge
- Statewide political shift: BJP’s position in Assam remains strong after the 2026 Assembly election.
- Local administrative profile: Sharma’s previous role as Nagaon Deputy Commissioner gives him constituency-level familiarity.
- Three-way arithmetic: Congress faces competition from AIUDF, reducing the possibility of a simple one-on-one transfer of anti-BJP votes.
- 2024 starting point: BJP was already the clear second-place party in Nagaon, so the organisation begins from a substantial base.
Why Congress remains a serious challenger
Congress won Nagaon decisively in 2024, and the party retains an established local network. Sibamoni Bora also brings Assembly-level experience. If the Congress vote remains close to its 2024 level and AIUDF does not expand significantly, the contest could become much tighter than this forecast suggests.
The AIUDF factor
Badruddin Ajmal’s candidature makes this a genuine three-way contest. AIUDF’s 2024 vote base was large enough to influence the winning margin even though it finished third. Any significant increase or decrease in AIUDF’s support can change the BJP-Congress arithmetic.
Polling and counting schedule

Final forecast
CareerSphere gives Debashish Sharma and the BJP a narrow edge, with low-to-moderate confidence. The large 2024 Congress lead means this is not a safe prediction. Turnout, AIUDF’s performance and the effectiveness of Congress’s local mobilisation could all overturn the forecast.
Editorial note: This is a pre-poll analytical forecast, not an exit poll. The official winner will be known after counting on October 9.
