bought Ṁ50 NO

Base rate: According to o3-DeepResearch, the average change is -3.8, and 4/14 (28.6%) presidents declined by 10 or more. I cannot confirm whether these calculations are correct, but they passed casual visual inspection of graphs

@Siebe you can't just pull up stats from the 60s, 70s and 80s when we live in a more polarized hyperpartisan era

@dlin007 yes I can. You can just weaken the strength of the base rate based on your theory ;) If anything, wouldn't polarization make approval less sensitive to policy outcomes?

@Siebe not exactly - it just means that Trump's floor is like 38% of Republicans who will approve of him no matter what and his ceiling is like 45% because Democrats will never approve of him (like they would a Republican president in the 70s). if he slides with independents, he will definitely crater, which is extraordinarily likely.

bought Ṁ1,000 YES

(this is the easiest YES bet in all of manifold)

@traders i have a class to run to and don't think this is gonna change, so for the purposes of this market, Trump's starting position is +2.5 net approval. Market will resolve YES if Trump is -7.5 net approval or worse on Feb 20 2026, NO if he's doing better than that, and N/A as discussed at market creation. 538 is now using some sort of blended average so there's no option to toggle just adults, so we'll use this page for resolution: https://projects.fivethirtyeight.com/polls/approval/donald-trump/

@traders since Trump's approval is still frozen from the end of his first term, i'll wait until exactly one month after he's in office and use his 538 net approval as the starting point. The resolution date will also move by a month. That captures the spirit of the market i think. I welcome any objections.

@dlin007 just realized there's multiple polling aggregates in that page, so to clarify, i'll use the "polls of adults" option

opened a Ṁ1,000 YES at 50% order

Placed limit at 50%

i already feel bad about this line, which is kind of a lock. A more uncertain line would be ~15 points
