Concentration on the HHI scale

Google Search alone holds 85% of this market. That makes it highly concentrated on the HHI scale — past the 2,500 line of the 2010 merger guidelines, and well past the 1,800 line the agencies' 2023 Merger Guidelines use.

Screening rule

Review posture uses published concentration thresholds, trend direction, and evidence status as separate signals. It does not estimate consumer harm or establish legal liability.

Public implication

Test whether the dominant firm controls access, switching, pricing, defaults, distribution, or other chokepoints that weaken consumer choice.
