The call

Ruten holds onto a long-tail collector niche while its parent's finances wobble and Shopee keeps pulling ahead in Taiwan.

Ruten is a 20-year-old online bazaar where Taiwanese people buy and sell used items and collectibles. It is owned half by PChome (a local tech company losing money) and half by eBay, and ranks fourth behind the much faster-growing Shopee. The main reasons it is hard to compete are that Shopee keeps getting bigger and faster, while AI shopping tools on other platforms steer buyers away from Ruten to places with better recommendations, and rival sites like Carousell are attracting the secondhand and collector buyers Ruten depends on. The one thing that could change this is if PChome sells or stops funding Ruten as a side business, or if eBay's ownership stake shifts due to takeover drama, forcing a major restructuring or sale.

Why
01
AI pressure: None apparent. No AI shopping agent or seller tool is named as pulling Ruten buyers away yet, but rivals are building such tools. Could AI do the core job? Only partly.
02
Bigger players: Shopee. Shopee's marketplace already dominates Taiwan e-commerce and keeps growing GMV fast, squeezing smaller players like Ruten. Could a giant copy it? Yes, easily.
03
What protects it. Two decades of collector and secondhand listings plus an entrenched seller base give Ruten a niche Shopee hasn't replicated.
What would change this call
PChome announces divestment, spin-off, or defunding of Ruten as non-core. Would show parent has given up on Ruten as a growth asset.
PChome reports 2025 annual results showing continued net loss or another rescue investment. Would show parent distress continuing to starve Ruten of resources.
Independent buyer/seller or GMV data for Ruten published outside aggregator estimates. Would show whether Ruten's user base is stabilizing or eroding to Shopee/Carousell.

Questions people ask
Is Ruten profitable in 2026?
Ruten's majority parent PChome Online posted a net loss in 2024 and needed a NT$2 billion rescue investment from Uni-President Group in January 2025 for roughly a 30% stake, suggesting the group remains financially strained rather than clearly profitable.
Who owns Ruten?
Ruten is a joint venture founded in September 2006 between PChome Online and eBay Inc, with an approximate 65% PChome / 35% eBay split. Parent PChome took a NT$2 billion investment from Uni-President Group in January 2025 for about 30% of PChome itself.
Could AI replace Ruten?
Unlikely to fully replace it, since Ruten's 20-year embedded Taiwan secondhand and collector seller base provides trust and localized liquidity AI can't easily replicate, but AI shopping assistants risk routing buyers to bigger rivals; Ruten added its own AI chatbot to the app by December 2025.
Who is Ruten's biggest competitor?
Shopee is Ruten's dominant competitor in Taiwan, with regional GMV growing 28.4% year over year to $32.2 billion in Q3 2025, while Ruten sits ranked around 4th in the market behind Shopee, Momo, and Taobao.
How does the eBay-GameStop dispute affect Ruten?
eBay, which holds roughly 35% of the Ruten joint venture, rejected an unsolicited $55-57 billion takeover approach from GameStop; GameStop raised its eBay stake to about 9.8-10% by July 21, 2026, creating uncertainty around eBay's future involvement in the Ruten JV.
When was Ruten founded and by whom?
Ruten launched in September 2006 as a joint venture between PChome Online and eBay Inc, merging their separate Taiwan auction operations into a single marketplace, per an InfoWorld report dated September 6, 2006.
