Will CMI declare a Millennium Prize Problem solved by December 31, 2026?

What this question means

The distinction between this question and its neighbours is the whole point. Two questions on this board ask whether an AI lab *announces* a Millennium Prize solution, both at 12%. This asks whether the Clay Mathematics Institute *declares one solved*, and sits at 7%.

An announcement is a claim. A declaration is an adjudication — it requires review, publication, and a formal process that is designed to take time precisely because the stakes are high.

That gap between 12% and 7% is the crowd pricing the distance between those two acts. Roughly speaking, it says that if a claim is made, confirmation within the same window is meaningfully less than certain.

Questions that look like duplicates often are not. Reading the verb carefully — announces, declares, confirms, completes — is usually where the actual forecasting problem lives.
