Uncle Sam is always watching, even if you’re a major brand like Pepsi or Walmart. The Federal Trade Commission, or what we will call FTC from here on, has filed a major lawsuit against Pepsi for colluding with Walmart to keep prices lower at Walmart stores than any other stores.

The U.S. Federal Trade Commission sued PepsiCo on Friday for offering preferential pricing to a large retailer, whom a source familiar with the matter confirmed was Walmart .

Outgoing agency Chair Lina Khan has filed a raft of measures during her last week in office.

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