Futarchy by definition is a system for group decision making. That means that you can’t use it for decisions that involve one person.
Why can’t an individual be the trivial group?
Like, it seems like I could set my lunch orders by having a prediction market on how I would rate lunches conditional on ordering them, ordering the item with the highest predicted rating, and then rating it afterwards. The main challenge is populating the prediction market with actors who expect the profit to be high enough to be worth the cognitive work, but that’s only indirectly related.

The decision making could be an individual but the information gathering needs multiple people.
I don’t expect there to be a good market for precictions of lunch rating especially since there’s one person who can easily make winning predictions.
