Report Summary
JPMorgan upgrades Mercari from Neutral to Overweight, raising its December 2026 price target from ¥3,200 to ¥5,000 based on a 23x P/E multiple applied to FY6/27 EPS estimates. The upgrade reflects accelerating GMV growth across the marketplace business since FY6/26, with growth drivers diversifying beyond trading cards and entertainment/hobbies into apparel, supported by trust-and-safety improvements (Safe Appraisal service, anti-resale measures) and AI-driven product recommendations. In fintech, AI-based credit screening is enabling transaction volume expansion while maintaining contained credit risk, and management is increasingly focused on strengthening the capital base.
