^ Cue, UChicago has had 10,000+ early apps since Fall of 2012. That’s not news. UC is well known for having the largest number of early apps. among its peers. The question is how many would become ED1 apps once they introduced that admission option. We know that it was at minimum about 4k for Class of '21 (fall 2016). The school has only gotten more popular since then (with lots of cc and reddit posts about chances in ED). Since the admissions peeps are saying 4-5k, that’s the number to use because its presumably accurate data. But if the early application numbers are increasing, that ED1 will be closer to 5k than 4k. That’s my bet. But we are quibbling anyway if we are off from one another by only 500 applicants
FYI Yale’s apps were a bit north of 35k this year; UChicago’s a bit south. So it’s not out of the ballpark to speculate that UChicago would see as many as 6k ED1 applications. However, the binding aspect probably does taper it relative to Yale’s. I’d put Yale’s numbers as an upper limit, and Brown/Columbia at the lower end, since UChicago easily achieved that right out the gate. So somewhere between current app volume range of 4.5-6k makes total sense, with the caveat that Covid might change things for everyone this admission cycle. Edit to add: agree with Marlowe that UChicago’s distinct “flavor” gives it a bit of a bump. Then it just becomes a matter of how many were admitted. 700 ED1’s might be high, of course.
