State attorneys general intensify merger oversight amid federal enforcement pullback

A federal-state coordination framework or Supreme Court clarification of state antitrust authority would reduce legal fragmentation, though this would require either legislative action or a major judicial ruling that typically takes years to materialize.

Continued state-by-state enforcement without federal harmonization would likely sustain elevated compliance costs and deal uncertainty for large acquirers, particularly in tech, creating a persistent drag on M&A velocity in concentrated sectors.

If state coalitions coordinate enforcement or win high-profile blocking decisions against major mergers, this could meaningfully constrain deal-making and capital allocation in technology and healthcare, putting downward pressure on valuations of acquisition-dependent business models.
