Hackathon Open

Enveda CASMI 2026 molecule identification competition on Kaggle

Enveda pays $50,000 to the top five teams that predict molecule structures from mass spectra. Online on Kaggle, final submissions close December 14, 2026.

The competition revives the CASMI name, which academic teams ran from 2012 to 2022, with the permission of its founders.

Quick answers

How are entries scored?

By mean reciprocal rank at 25. Each entry ranks up to 25 candidate structures per molecule, and only the first correct guess counts.

Can pretrained models be used?

Yes. Freely and publicly available external data is allowed, including pretrained models.
