The UK Competition and Markets Authority (CMA) has formally opened a phase 1 investigation into eBay’s proposed purchase of Depop. Multiple reports describe the action as the regulator’s initial assessment of whether the deal could raise competition concerns in the UK. The CMA’s inquiry follows eBay’s announcement of its plan to acquire Depop, a UK-founded online fashion marketplace. In this phase, the CMA typically examines potential impacts on competition, including whether the transaction could lead to higher prices, reduced choice, or less innovation for consumers, as well as any effects on businesses operating in related markets. The reporting indicates that this is the regulator’s first-stage review, which is used to determine whether the case can be cleared at phase 1 or needs further scrutiny under a more in-depth phase 2 process. No decision has been reported yet, and the investigation remains ongoing as the CMA evaluates the proposed acquisition.
