Dear participants, some of you have noticed issues with the validation results, as well as the leaderboard and have brought these to our attention. Thank you very much! In particular, the problem was as follows: Evaluation was not done for all of the 219 cases, but instead only for a subset of around 70 cases, the others were empty. In the past couple of days we have worked on solving these issues and **a fix to the root cause has been implemented**. From now on, **we expect all submissions to be evaluated correctly and to produce valid results for all cases! ** If you have past submissions you urgently need re-evaluated, please reply with your submission IDs (but please keep in mind we will be running these sequentially). Otherwise, **feel free to keep submitting** as usual, as **all new entries will use the updated environment**. We apologize for any inconvenience and hope that you won't have any more issues moving forward. If you run into any related or other problems, please do not hesitate to reach out to us! Best of luck to all of you! Paula for the BraTS 2026 Organization Team
