CMA opens phase one merger inquiry into eBay's $1.2 billion acquisition of Depop with an August deadline
The Competition and Markets Authority (CMA) has formally launched a phase one investigation into eBay's proposed acquisition of fashion resale platform Depop, with the review period beginning on 9 June 2026 and a statutory deadline of 6 August 2026 to decide whether to extend to a more detailed phase two investigation. The CMA confirmed that the merger notice submitted by eBay and Depop meets the requirements of the Enterprise Act 2002, triggering the formal review process. The regulator had previously invited comments on the transaction between 23 April and 8 May before entering the pre-notification stage. The deal — a $1.2 billion (£890 million) all-cash acquisition by eBay of Depop from Etsy — was first announced in February 2026. eBay CEO Jamie Iannone described the acquisition at the time as an opportunity to deepen the company's relationship with younger shoppers, citing Depop's strength in the pre-loved fashion category and its social-forward marketplace model. The CMA's scrutiny focuses on whether the combination of eBay's general marketplace with Depop's specialist second-hand fashion platform could raise competition concerns in the UK market, particularly in the online resale and recommerce sector — a fast-growing segment that also includes platform competitors such as Vinted. The phase one investigation is a standard first step under UK merger control, and the CMA has stated it will seek to complete its review as quickly as possible, though statutory deadlines can be extended in certain circumstances.
Why this matters
The CMA's phase one opening under the Enterprise Act 2002 is a standard but commercially significant step — it creates a live regulatory timetable that the parties and their advisers must manage carefully. The key question is whether the CMA finds a realistic prospect of a substantial lessening of competition (SLC) in online resale marketplaces, which would trigger a phase two investigation with considerably greater disruption and cost for both parties. The online recommerce sector is growing rapidly, and the CMA has shown willingness to scrutinise digital marketplace consolidation closely following its reviews in other platform sectors. If referred to phase two, remedies discussions — potentially including behavioural undertakings or structural divestitures — would add significant complexity and timeline to the deal. Competition lawyers on both sides will be focused on preparing merger control submissions that frame the relevant market definition narrowly enough to reduce SLC risk.
On the Ground
On a CMA phase one review, a trainee would be helping draft the regulatory notification submission — compiling evidence on market shares, competitor analysis, and customer survey data for submission to the regulator. Maintaining a CP checklist tracking the CMA's statutory deadlines, and co-ordinating document production requests from the regulator, would be core daily tasks.
