Ken Griffin’s $2 billion gift is intended to create a Carnegie Mellon University campus in Miami’s Wynwood neighborhood. The donation has been described as the largest ever to a higher education institution.

His choice has raised a question in a city that already has universities: why fund a new campus instead? Florida International University is a large public university known for helping students from low- and middle-income families advance. The University of Miami is a selective private university with a substantial medical research program.

Local and national observers cite Carnegie Mellon’s standing in technology education and Griffin’s vision for Miami as possible factors, rather than a confirmed explanation from Griffin. In U.S. News & World Report’s overall rankings, Carnegie Mellon is 14th, the University of Miami is 55th and FIU is tied for 100th. Carnegie Mellon also ranks at the top for computer science and artificial intelligence.

The choice comes as Miami’s existing universities have yet to produce the workforce sought by finance and technology companies moving to the city.
