The Federal Trade Commission on Friday sued PepsiCo in a last-minute blitz of lawsuits before the end of the Biden administration, alleging that the beverage giant forced many consumers to pay higher prices by giving Walmart unfair pricing advantages.

The FTC is suing PepsiCo for allegedly rigging the market by offering “unfair pricing advantages” that can contribute to inflation.

A lawsuit filed by the Federal Trade Commission alleges that food and beverage maker PepsiCo engaged in illegal price discrimination by giving unfair price advantages to one big-box retailer.
