The call

11st's revival depends on Coupang staying wounded, not on anything 11st has built that Coupang cannot copy.

11st runs an online marketplace where people buy and sell products, similar to Amazon or eBay. Coupang, the market leader, can copy everything 11st does and already has most of the customers, making it extremely hard for 11st to catch up or stand out. The company has lost money for seven years and is banking on Coupang's recent data breach to win back shoppers, but if Coupang fixes that problem and customers return by the end of 2026, 11st will be stuck as the permanent second choice with no clear way to grow or sell itself.

Why
01
AI pressure: ChatGPT and Gemini shopping agents (Shopee already integrated with ChatGPT). If shopping moves inside chat agents, sellers may skip 11st's app entirely, and Coupang or Naver could win the integration race first. Could AI do the core job? Yes, likely.
02
Bigger players: Coupang. Coupang holds roughly 2.3x 11st's user base and can copy any loyalty or pricing move 11st makes within a quarter. Could a giant copy it? Yes, easily.
03
What protects it. SK Planet's fresh 60 billion won injection and Coupang's temporary breach fallout buy 11st a narrow window to gain users.
What would change this call
Coupang's MAU and brand metrics return to pre-breach trend by Q4 2026. Would show 11st's 2025 revival window closes and it reverts to permanent #2.
11st reports company-wide (not just open-market segment) quarterly net profit. Would show the turnaround extends beyond one profitable segment to the whole business.
11st announces a ChatGPT Korea or Naver HyperCLOVA shopping-agent integration. Would show 11st gained an AI-shopping channel Coupang doesn't yet have.
Key numbers
  • 440 billion won accumulated losses since 2018 (2025-12-29)
  • 13.24M MAU vs Coupang's 24.6M active customers (2025-Q4)
  • 60 billion won fresh injection from SK Planet (2025-12-29)
Named risks
  • Coupang recovery post-breach could erase 11st's temporary competitive window by late 2026. Severity: high
  • No structural moat; Coupang can replicate any 11st feature or promotion with far greater capital. Severity: high
  • 440 billion won accumulated losses since 2018 with no confirmed path to sustained company-wide profit. Severity: medium
  • Chinese C-commerce platforms AliExpress and Temu continue pressuring from below on price. Severity: medium
  • No frontier-model shopping integration while regional peers like Shopee move ahead on agentic AI. Severity: medium

Questions people ask
Is 11st profitable in 2025?
11st's open-market segment posted operating profit for 7 consecutive months through September 2024, but the company has accumulated roughly 440 billion won in losses since its 2018 spin-off, per SK Planet's own December 29, 2025 disclosure, so it remains unprofitable company-wide.
Who owns 11st now?
SK Planet owns 100% of 11st after SK Square sold its controlling stake (valued at 660.7 billion won) to SK Planet on October 29, 2025, paying 467.3 billion won to financial investors including the National Pension Service.
Could AI replace 11st's shopping discovery role?
Yes, product discovery and recommendation are exposed workflows; 11st launched its own generative-AI 'Ai Feed' curator in October 2024, but as of June 2026 it has no ChatGPT or Gemini integration while regional peer Shopee shipped a live ChatGPT shopping app on June 22, 2026.
Is Coupang 11st's biggest competitor?
Yes. Coupang dominates with 24.6 million active Product Commerce customers in Q4 2025 versus 11st's 13.24 million mobile MAU in April 2024, though Coupang was fined 624.9 billion won on June 11, 2026 over a data breach, creating a temporary opening SK Planet is funding 11st to exploit.
Will 11st IPO?
No confirmed IPO timeline exists as of December 2025. 11st missed its original September 30, 2023 IPO deadline under the 2018 shareholder agreement, and that dispute was resolved via SK Planet's full-stake buyout on October 29, 2025 instead of a public listing.
How does 11st compare to Chinese platforms AliExpress and Temu in Korea?
As of April 2024, 11st led both with 13.24 million mobile MAU versus AliExpress's 10.58 million and Temu's 9.74 million, per Nielsen Korean Click data, holding the #2 spot in Korea behind Coupang.
