618's old battleground becomes an AI proving ground

Platforms and tactics

China’s mid‑year shopping festival 618 has shifted from a price war into an AI arms race. Major platforms — JD (京东), Tmall (天猫) and Taobao (淘宝) from Alibaba (阿里巴巴), Douyin (抖音) and its Doubao (豆包) assistant from ByteDance (字节跳动), Pinduoduo (拼多多), Kuaishou (快手) and Xiaohongshu (小红书) — are all rolling AI into pricing, discovery and fulfilment as the headline feature of their promotions. JD is positioning “AI across scenarios + deep discounts” as its theme for the campaign, Tmall has upgraded coupons and tied in Alibaba’s Qianwen (千问) assistant to Taobao, and Douyin has reportedly integrated Doubao for one‑click AI shopping and price comparison across its short‑video inventory.

Different AI paths

Each platform’s AI play reflects its core strength. JD is doubling down on supply‑chain and logistics intelligence to reduce costs and improve fulfilment; Alibaba stresses demand–supply matching and AI agents for merchant tools and conversational shopping; short‑video platforms like Douyin and Kuaishou lean on content‑to‑commerce flows, using AI to automate recommendation, content production and instant conversion. It has been reported that Doubao has monthly active users in the hundreds of millions, giving ByteDance a large traffic pool to test closed‑loop “ask–compare–buy” experiences — but conversion dynamics remain to be proven.

Risks and geopolitical backdrop

AI’s rapid embedding into commerce brings new frictions. Smart recommender agents risk deepening information cocoons and narrowing consumer choice; algorithmic preference for high‑conversion blockbusters could squeeze niche brands and dampen market diversity; and faster, AI‑driven checkout may shrink browsing time and undermine ad‑based monetisation models that many platforms rely on. Against a backdrop of U.S. export controls on advanced semiconductors and broader trade tensions, Chinese platforms are also emphasizing software‑side AI optimization as a way to extract more value from existing hardware and domestic supply chains.

What to watch

This 618 is a large, public stress test: will AI measurably boost conversion, merchant efficiency and logistics, or will it concentrate winners and create new regulatory and commercial headaches? Platforms will report results after the holiday — and those numbers will tell whether AI is merely an added layer of convenience or the structural pivot that redefines e‑commerce economics in China.
