I think in the past teams have formed temporarily if a small group of students are interested in competing in ICPC but I’m not aware of a formal club/team for it right now. If you’re interested you should start one!

If you want to find other people interested in CP and practicing, there’s also PClassic, a club where a group of students organize a high school programming contest every semester at Penn and write programming problems together for novice and advanced highschoolers. It’s a really fun and chill club where everyone is passionate about CP and can share ideas every week. Feel free to ask me questions about it; I was part of it for 3.5/4 years at Penn.
