Is Mercari profitable in 2026?

Yes. Mercari's core operating profit was 14.6 billion yen in Q3 FY2026 (reported 2026-05-11), up 66% year over year, on revenue of 61.0 billion yen, up 22% YoY. FY2025 core operating profit was 27.5 billion yen, up 46% YoY, on record revenue of 192.6 billion yen.

Did Mercari's US business ever make money?

Yes, for the first time. Mercari US posted its first-ever full-year operating profit of 900 million yen in FY2025 (ended 2025-06-30), reversing a decade of losses since its 2014 launch, following a fee-policy reversal and 2024 layoffs.

Could AI replace Mercari?

Unlikely to replace it outright. Mercari's AI Listing Support already cuts listing time from minutes to about 15 seconds for over 20 million monthly users, but the company's moat is its proprietary dataset of 4 billion cumulative listings and logistics integrations, which it is using to train its own search AI via Japan's GENIAC program (2026-06).

Who is Mercari's biggest competitor?

In North America, eBay dominates resale traffic with 532 million-plus monthly visits as of 2026-03-14, while Mercari US GMV was just $211 million in Q3 FY2026. In Japan, Yahoo Japan and Rakuten are domestic rivals but have not dislodged Mercari's lead with 23 million monthly active users.

Mercari is publicly traded on the Tokyo Stock Exchange under ticker 4385, having IPO'd on 2018-06-19 and raised about 130.5 billion yen (~$1.2 billion). Founder Shintaro Yamada remains CEO. Market capitalization was approximately 754.6 billion yen as of 2026-07-22.

Did Mercari lay off employees?

Yes. Mercari US underwent a mass layoff in mid-2024 reportedly affecting about 45% of its full-time US staff, tied to a botched fee-structure change that triggered seller and buyer backlash before being partially reversed in January 2025.

The call

Japan's business is large, profitable, and growing; the US business just turned its first full-year profit and still has to prove that wasn't a one-time fee-reversal fluke.

Mercari runs an online marketplace where people buy and sell used items, similar to eBay or Facebook Marketplace. In Japan, the company has built something hard to replace: 23 million monthly users, billions of listings, and deals with delivery companies and payment processors that new competitors would struggle to copy quickly. The US business is the problem. Mercari has cycled through three leaders in two years, reversed a fee increase that hurt trust, and only just turned profitable last year after a decade of losses, which raises questions about whether that profit was real or a one-time event. The biggest threat to Mercari's whole model is artificial intelligence. If Google or OpenAI build AI shopping agents that help people find and buy items directly without visiting Mercari's app, customers might never visit the marketplace again. The next test is whether the new US leader can keep profits growing or if the company slides back into losses.

Why

AI pressure: OpenAI/Google agentic shopping layers. If shopping agents pick where to buy used goods, Mercari's app could get skipped for discovery even as it still handles the transaction. Could AI do the core job? Unlikely.

Bigger players: Rakuten and LINE Yahoo in Japan, eBay in the US. Rakuten and LINE Yahoo fight for the same Japanese shoppers, while eBay still owns most US resale traffic Mercari wants. Could a giant copy it? No, they are blocked.

What protects it. 23 million monthly Japan users, four billion listings of behavioral data, and built-in logistics and fintech that's hard to copy fast.

What would change this call

Q4 FY2026 earnings (due August 5, 2026) show US GMV growth alongside profit, not just cost cuts. Would show US turnaround is durable, not a one-time fee-reversal gain.
Jeff LeBeau's US CEO tenure (from July 1, 2026) lasts multiple quarters without another leadership change. Would show US management instability has ended.
Outcome of Illinois BIPA mass-arbitration claims over facial-geometry data. Would show scale of legal/financial liability facing Mercari's US operations.

Key numbers

Core operating profit up 46% YoY to ¥27.5B (2025-06-30)
23 million monthly active users in Japan (2025-Q4)
US GMV $211M, up 18% YoY (2026-05-11)

Named risks

US segment fragility: three leadership changes in two years plus a 2024 fee-policy backlash. Severity: high
Illinois BIPA mass arbitration over biometric facial-geometry data collection during verification. Severity: medium
Agentic AI shopping assistants could route purchases around Mercari's discovery layer. Severity: medium
Discontinuation of Mercari Hallo shows execution risk in new venture bets. Severity: low
Conflicting GMV figures across sources point to inconsistent external reporting clarity. Severity: low
