The Putnam, per its website (https://maa.org/putnam/), is the preeminent mathematics competition for undergraduate college students in the United States, Canada, and Mexico. 

This market resolves N/A if, to the best of my understanding, no community college has signed up for the Putnam. Else it resolves YES iff a community college places top 5 according to the announcements. Barring an unexpected change of policy, team rankings are determined only by the sum of a school's top three scores.

As far as I know no community college has placed in the top 5 at any past Putnam. Perhaps history will be made soon.

Warning for the uninitiated: the world of contest math is very small and a school's rankings are not necessarily indicative of the strength of its math department. For instance, MIT dominates the contest while Princeton, at least in recent years, does not do very well. It would be hard to argue that MIT's math department is vastly superior to Princeton's. School rankings often switch wildly as a few strong contest math students move here and there.
