They seem to have sprouted all over Midtown in a short span of time, and now there are like half a dozen active supertall developments or proposals in Chicago.
I would assume its because land values have gotten high enough to make construction of such towers economically feasible. Tall and thin towers are typically pretty cost prohibitive since the elevator core tends to take up more square footage of each floor plate the taller the tower is, and keeping it thin reduces the overall space on each floor to work with. Not to mention the additional engineering it takes to build a super tall tower compared to a mid size one.

Just my two cents.
