How long does it have to hold for it to be considered that peace has been attained? A week? A month?

Don't know. That's up to the Committee. Though I don't think that's really going to end up being much of an issue. Per media reports, they already selected this year's winner on Monday, and they won't meet again before the Prize is announced. Since it probably wasn't Trump, he'd first be considered for the 2026 Prize - which means that the Committee will have had a full year to assess what happens as a result of the ceasefire.
