What is happening?
Unity Technologies announced on March 26, 2026, it will sunset the ironSource Ads Network's direct demand business effective April 30, 2026, marking the end of most remnants from its controversial 2022 $4.4B acquisition of the Israeli ad-tech firm.
The network, once expected to power Unity's mobile monetization, will cease new publisher onboarding and campaign creation from April 15. Publishers must migrate ad inventory before deadline to avoid revenue loss. Unity is also divesting Supersonic (hits like Bridge Race) via financial advisor, leaving primarily the IronSource Exchange for programmatic ads.
The moves “simplify operations” as Unity pivots to its high-growth Unity Vector AI ad platform, which now drives ~50% of Grow Solutions revenue. No impact on existing IronSource SDK users for programmatic fill. This follows years of integration struggles, executive exits, and Unity's 2024 layoffs.
As of March 28, 2026, publishers have ~1 month to transition. Unity exceeded Q1 2026 revenue guidance despite the cuts.
