Do the Ivy League schools share prospective applicant info when making decisions about whom to admit?
That's a great question! I don't believe applicant information is shared before decisions are made, but we have ample evidence that lists of early decision accepted students are shared. Remember that Early Decision is a binding commitment to attend the college if they let you in. You also promise to withdraw all your other submitted applications when you are accepted at your ED school. If you don't follow these rules, your acceptance can be rescinded. This does happen, and the only way they would know you didn't withdraw your other applications is if the colleges shared the names of admitted students. However, trying to share the details of the tens of thousands of Ivy applicants before decisions are made would increase the Admissions Committees workload 8-fold.

That looks like a timely question and answer that even the Justice Department would like to learn more about! Justice Department Investigates Early-Decision Admissions: Focus appears to be how some colleges share information about those admitted early. Common App asks applicants to consent to the practice. https://www.insidehighered.com/admissions/article/2018/04/09/justice-department-starts-investigation-early-decision-admissions
