The call

LINE's messaging graph across Japan, Thailand, and Taiwan stays intact, but its ad and search revenue is flattening as AI assistants take over research and shopping tasks.

LINE is a messaging app that 80 percent of Japanese people use for texts, payments, and shopping. Rivals like WhatsApp and WeChat tried to take over Japan for ten years and failed because LINE is too deeply built into how people already communicate and pay each other. The real threat is that AI assistants like ChatGPT and Google Gemini are answering customer questions directly instead of showing ads on LINE, which is why LINE's advertising business barely grew last year. LINE is trying to fight back by using AI to help its one million business accounts talk to customers better using their own customer data, but it is a race against time: only 16 percent of Japanese people use AI daily right now, and if that number jumps quickly, LINE has to prove it can make money from AI faster than the ads disappear.

Why
01
AI pressure: ChatGPT and Gemini. AI assistants pull shopping and search queries away from LINE's ad and search surfaces, pressuring the Media Business segment. Could AI do the core job? Only partly.
02
Bigger players: Meta/WhatsApp, WeChat, KakaoTalk. These messaging rivals have tried for a decade to break into Japan, Thailand, and Taiwan and have not displaced LINE's user base. Could a giant copy it? No, they are blocked.
03
What protects it. LINE's near-total penetration in Japan, Thailand, and Taiwan, plus deep ties to PayPay payments and 1M+ business accounts, keep users and merchants locked into its graph.
What would change this call
LY's Media Business revenue growth over next two quarterly reports (Aug 2026, Nov 2026). Continued flat or declining trend would show AI assistants displacing ad/search revenue.
Adoption metrics for Agent i Biz and LINE OA AI Mode after their 2026 launches. Weak uptake would show LY failing to monetize merchant data against AI-native rivals.
Outcome of Kakaku.com acquisition bidding between LY/Bain and EQT. Losing the deal would show LY struggling to secure commerce data assets against private equity rivals.

Questions people ask
Is LINE (LY Corporation) profitable in 2026?
Yes. LY Corporation, LINE's parent, reported record FY2025 consolidated revenue of ¥2,036.3 billion (up 6.2% YoY) and record adjusted EBITDA of ¥496.6 billion (up 5.5% YoY) as of May 8, 2026, though its Media Business segment was nearly flat at ¥734.5 billion.
Who owns LINE?
LINE's operator, LY Corporation (TSE: 4689), is majority-controlled by A Holdings Corporation, which held about 62.4-62.5% of LY voting rights as of June 30, 2026. A Holdings is a 50/50 joint venture between SoftBank Corp and Naver Corporation of South Korea.
Could AI replace LINE's business accounts or customer service?
LY is actively automating this itself: it launched LINE OA AI Mode and 'Agent i Biz' (planned August 2026) to let its 1 million+ LINE Official Business Accounts run AI-driven customer support and marketing, rather than waiting for outside AI to displace human-staffed chat.
Is LINE's biggest threat WhatsApp or WeChat?
Neither has displaced LINE despite over a decade of trying in Japan, Taiwan, and Thailand. LY's structural analysis frames the bigger risk as frontier AI assistants like ChatGPT and Gemini disintermediating ad and search revenue, not rival messaging apps taking users.
Is LINE losing ad revenue to ChatGPT or Gemini?
LY's Media Business (LINE plus Yahoo Japan) grew only 0.4% YoY to ¥734.5 billion in FY2025 versus 6.2% group-wide growth, a flatness the company's own analysts flag as an early signal of AI-assistant substitution pressure on ad and search revenue.
What is Agent i and why did LY Corporation launch it?
Agent i is LY Corporation's unified AI agent brand, launched April 19-20, 2026, merging the former 'LINE AI' and 'Yahoo! JAPAN AI Assistant' into one tool across both apps, intended to keep AI-driven shopping and search queries inside LY's own ecosystem rather than ceding them to outside chatbots.
