A settlement, which is not imminent, would seek to resolve concerns that Amazon's contracts with publishers prevented other e-book distributors from competing in the English- and German-language markets, an unnamed source told the Journal. Regulators allege that Amazon abuses market power and pushes illegal terms on publishers, the Journal said, citing the source.
CNBC has reached out to Amazon for comment on the report.
Amazon is one of many U.S. technology companies that has faced scrutiny for its business practices.
The European Commission is also intent on levying a fine against Google, the Journal reported earlier this week. Like Amazon, Apple's tax and e-book practices have also come under fire from the European Commission.
