Key Points

  • The post creates a discussion thread for IJCAI-ECAI 2026 final decision notifications, expected to go out starting April 29, 2026 (AoE) with timing that may vary by local rollout of the ChairingTool.
  • The author notes they couldn’t find official 2026 desk/Phase 1 reject statistics or counts moved to Phase 2, so they estimate the final acceptance rate using recent IJCAI main-track acceptance rates (about 14% in 2023–2024 and roughly 17–19% in 2025).
  • Based on these assumptions, the author guesses IJCAI-ECAI 2026 may end with an acceptance rate around 15–18%.
  • For papers that reached Phase 2, the post suggests a higher acceptance likelihood (estimated around 22–28%), while emphasizing this is speculative because Phase 2 paper counts have not been published.
  • Participants are asked to keep discussion restricted to non-confidential information, focusing on ChairingTool status changes, decision timing, visible review/meta-review changes, and final updates without sharing reviewer identities or confidential review text.

Creating a discussion thread for IJCAI-ECAI 2026 final decision notifications.

The official paper notification date is April 29, 2026 AoE, so decisions may appear at different local times depending on the ChairingTool rollout.

I could not find official 2026 statistics on the number of desk rejects, Phase 1 summary rejects, or papers moved to Phase 2. For estimating the final acceptance rate, I think the latest IJCAI years are more relevant than older IJCAI-ECAI data. Recent IJCAI main-track acceptance rates were around 14% in 2023, 14% in 2024, and somewhere around 17-19% in 2025 depending on the reported count.

Based on that, my rough guess is that IJCAI-ECAI 2026 may land around a 15-18% final acceptance rate. For papers that reached Phase 2, the acceptance probability should be higher, perhaps around 22-28%, but this is only an estimate since the number of Phase 2 papers has not been released.

This thread is for general discussion of ChairingTool status changes, decision timing, visible review/meta-review changes, and final decision updates. Please keep the discussion limited to non-confidential information and do not post reviewer identities or full confidential review text.

Good luck to everyone waiting.
