If the 1 million dollar prize pledged by the Clay Institute of Mathematics for the resolution of the Navier Stokes problem is taken, then this resolves YES. (Typically : someone solves the problem and accepts the money)

If it’s clear consensual that it won’t be taken, then this resolves NO. (For example the Clay Institute of Mathematics ceases to exist and no money related to this problem is saved to be awarded later, or someone solves the problem, is awarded the money and refuses it.)

If the money is awarded and redirected (like idk someone gets the prize and asks for it to be given to MIRI), this resolves YES.

In case the resolution is conflictual, I’ll use my judgement, so I won’t bet on this market.
