The European Commission opens an in-depth investigation into Microsoft's proposed $69B Activision Blizzard acquisition and sets a March 23 decision deadline
Context & Ripple Effects
The EU escalation follows a provisional November review deadline and reports that Microsoft had not filed remedies before the Commission moved toward a deeper probe. It also puts the transaction alongside the UK's in-depth CMA review, rather than on a fast regulatory-clearance track.
First-order effects
- Microsoft and Activision Blizzard now face a full European Commission investigation, with the Commission targeting a March 23 decision.
- The deal's EU timetable moves beyond the initial review phase, extending regulatory uncertainty for both companies.
Second-order effects
- Microsoft must manage parallel in-depth scrutiny in the EU and UK, increasing the importance of any remedies it offers to address regulators' concerns.
- The Commission's process gives European regulators more time to test the transaction's effects before deciding whether to clear, condition, or block it.
Third-order effects
- If this pattern persists, large cross-border technology acquisitions will increasingly be shaped by lengthy, overlapping national and regional antitrust reviews rather than a single quick clearance process.
The trend: Major technology acquisitions are facing more intensive multijurisdictional antitrust scrutiny, with remedies and review timelines becoming central deal variables.
