What happened
Mixed outcomes. The competition awarded its prizes, and Mati subsequently received a verified credit issuance. Those are milestones in demonstration and certification. Deployment at gigatonne scale and storage lasting centuries remain substantially larger claims.
- Mati won the grand prize; three runners-up and separate XFACTOR awards recognized other approaches. XPRIZE Carbon Removal Competition
- Mati received the $50 million grand prize in April 2025, with scientific leadership connected to Yale. Yale-Related Nonprofit Wins $50 Million XPRIZE Carbon Removal
- Isometric records 209.08 certificates issued to Mati on June 17, 2026, naming Earthood as verifier and Enhanced Weathering in Agriculture v1.2 as protocol. 209.08 certificates issued to Mati
What might explain it
Plausible
A common demonstration requirement may make otherwise dissimilar removal approaches easier for funders to compare. XPRIZE Carbon Removal Competition
Alternative explanation: Selection may mostly identify teams already advantaged by capital, research partnerships, and measurement infrastructure.
Plausible
Certification can create a transaction-ready signal before society can directly observe the full claimed storage period. 209.08 certificates issued to Mati
Alternative explanation: That signal depends on protocol assumptions and verification; buyers may instead rely primarily on institutional reputation or contractual protection.
Questions to take into practice
- Keep measured removal, modeled durability, credits issued, and credits sold as separate quantities.
- Ask what follow-up evidence would change confidence after judges announce a winner.
What remains uncertain
- The 209.08-certificate registry transaction covers a particular issuance, not the competition’s total measured removal. Long-run costs and storage durability remain questions beyond that transaction and the award.
