NEW YORK, May 17 (Reuters) - Private equity firm Thoma Bravo is exploring a sale of Instructure, a U.S. education software provider with a market value of $3 billion, people familiar with the matter said on Friday.

Thoma Bravo, which took Instructure public in 2021 and now holds an 83% stake in the company, has tapped JPMorgan Chase to gauge the interest of potential buyers that include other buyout firms, the sources said.

The sources cautioned no deal is certain and requested anonymity because the matter is confidential.

Thoma Bravo, Instructure and JPMorgan did not immediately respond to requests for comment. (Reporting by Milana Vinn in New York Editing by Greg Roumeliotis)
