The Everything App

The “everything app” that Western technologists talk about building already exists, and it is Chinese. WeChat, Weixin at home, is a messaging service, a payments network, an app platform and a services portal fused into one, and by the end of September 2025 it had more than 1.4 billion monthly users.^[1]

Its most important layer is the least visible to outsiders: mini-programs, small apps that run inside WeChat without a separate download. There are around 4.3 million of them, and in 2024 they moved on the order of 8 trillion yuan in transactions; the mini-games alone have more than 500 million monthly users.^[1][3] This is an entire app economy running inside a chat app, bypassing the traditional app store altogether.

An app store, a bank, a messenger and a government-services desk, in one app on 1.4 billion phones. The West keeps trying to build this; China runs it.

The payment rails underneath

Beneath the superapps sit the payment rails they made ubiquitous. WeChat Pay handles more than a billion commercial transactions a day, and together with Ant Group’s Alipay, itself past a billion users, the two control roughly 96% of China’s mobile-payment market.^[1][4] Payments are the connective tissue that makes the everything-app model work, and China’s are a near-total duopoly.

One honest caveat: exact payment-share splits vary by methodology, and the reasons the model has not been replicated in the West, app-store gatekeeping, antitrust scrutiny, separate payment rails, no single dominant messenger, are analysis rather than a single statistic.

The investment case

The superapp is China’s most distinctive platform innovation, and its significance is structural: by owning messaging, payments and the mini-program layer at once, WeChat and Alipay sit at the centre of Chinese digital life in a way no Western platform matches. For investors that platform position is the ultimate moat; every transaction, service and mini-app compounds the others’ value and raises the cost of leaving, and it is why the Chinese consumer internet is organised around two gatekeepers rather than a dozen apps. It is also why regulators watch them so closely. The everything app is not a feature; it is the operating system of Chinese consumer life, and that is exactly what makes it both powerful and politically exposed.
