International Data Group Stock Forecast
IDG shows no indication of pursuing an IPO under Blackstone ownership. Private equity firms typically hold portfolio companies for four to seven years before exit, meaning a sale or public listing could emerge in the mid-2020s. The March 2025 sale of the Foundry publishing division to Regent LP suggests Blackstone is restructuring IDG around its core IDC research business ahead of a potential future exit.
