Dear @BraTS2026Participants, In response to numerous requests from participating teams, we have _extended the deadline_ for Docker and short paper submissions with one week. You now have **until July 30th** to continue developing your model, uploading your validation results, and submitting your manuscript (the previous deadline was July 23rd). Please note that this is a **strict, hard deadline**, and there will be no further extensions. We would like to remind you that a valid submission includes the following components: - A submitted containerized version of your algorithm as a Docker image - A paper describing the methods and results submitted on the [OpenReview platform](https://openreview.net/group?id=MICCAI.org/2026/Challenge) - A signed Copyright form, which will be provided to you by the challenge organizers All other dates in the BraTS timeline will remain the same. Cordially, BraTS Organization Team

Hi, Thank you for the extension to July 30th. Given the volume of last-hours questions still coming in, would it be possible to get a short additional extension until the end of day Sunday, August 2nd? This would give teams a small buffer over the weekend to finalize Docker submissions, papers, and signed copyright forms without any rush-related errors. We understand if this isn't possible given the "strict, hard deadline" note, but wanted to ask given the circumstances. Thank you for your continued support and for organizing this challenge.
Hi, Can I confirm the exact time which the challenge closes on the 30th? - the time by which we must have uploaded out paper, our docker submission and our copyright forms? On operreview.net the subtext states that the submission deadline (which I assume is for papers) is 31st July at 2:59pm. I'm away from my desk and have been delayed so looking to utilize every additional hour. Thank you very much! Best,
Hi, could you please confirm when and where the Copyright Form will be provided? Will it be sent after the OpenReview paper submission? Thank you!
