The FTC will face hurdles to block Microsoft's Activision deal, as courts are skeptical of vertical merger challenges where two companies don't compete directly
Ms. Khan, the chair of the Federal Trade Commission, has staked an ambitious trustbusting agenda on a case that may be difficult to win.
Context & Ripple Effects
The FTC's case follows the agency's formal attempt to block the $69B transaction after earlier reports that staff doubted Microsoft and Activision's defenses. The dispute tests whether the agency can turn concerns about Microsoft’s position in gaming into a viable challenge to a deal between companies that do not directly compete.
The deal had already been framed as a major test for Khan’s antitrust-focused FTC after Microsoft’s earlier studio acquisitions drew regulatory attention. A later court rejection of the FTC’s preliminary-injunction request underscores why the legal theory matters beyond this transaction.
First-order effects
- The FTC must meet a demanding legal burden to halt Microsoft’s acquisition of Activision, while the companies face continued deal uncertainty rather than an immediate prohibition.
- Microsoft’s alleged ability to disadvantage gaming competitors becomes the core of the case, shifting the fight from direct market overlap to prospective control over a major game publisher.
Second-order effects
- Gaming competitors gain a formal venue for raising concerns about Microsoft’s post-deal conduct, but the FTC must translate those concerns into evidence that satisfies courts skeptical of vertical-merger theories.
- A weak showing would narrow the FTC’s leverage in negotiating constraints on the transaction and strengthen Microsoft’s position in defending the acquisition.
Third-order effects
- If courts continue to reject vertical theories without direct competition, U.S. merger enforcement will need more concrete evidence of foreclosure to constrain platform owners’ acquisitions of suppliers and content producers.
- The case is an early test of whether a more aggressive FTC can reshape vertical-merger doctrine through litigation, rather than relying on existing judicial standards.
The trend: Platform-gatekeeper enforcement is increasingly turning on whether regulators can prove that control of content or suppliers harms downstream rivals even without a direct horizontal merger.
