The quiet takeover: Ubuntu on WSL is about to surpass native desktop Linux

Canonical, the company behind Ubuntu, expects a surprising milestone in 2026: more people will be running Ubuntu inside Windows Subsystem for Linux (WSL) than on native desktop Linux. Jon Seager, Canonical's VP of Engineering, told The Pragmatic Engineer in April 2026 that Ubuntu's WSL user base is growing significantly faster than its native desktop counterpart, and he predicts it will overtake native desktop installations within months, before the end of 2026 .

This is not a published market measurement — Canonical has not disclosed the underlying WSL user count, its definition of an active user, or a comparable native-desktop total . But if Seager’s forecast holds, it signals a fundamental shift in how developers interact with Linux.

Why Ubuntu inside Windows is growing so fast

Seager identified several factors driving the rapid adoption of Ubuntu on WSL, all centered on the reality of enterprise development.

Enterprise developer hardware. Most developers at large companies are issued Windows laptops, not native Linux machines. WSL lets them run a full Ubuntu environment — including Linux-compatible AI and machine learning toolchains — without changing the corporate desktop OS or fighting IT policies .

AI and ML workflow demand. The surge in AI and machine learning development has made GPU-accelerated Linux environments essential. WSL now provides near-native GPU passthrough for NVIDIA CUDA, AMD ROCm, and Intel AI accelerators, making it the default choice for developers on managed Windows fleets who need to train or run models locally .

Ubuntu’s default distribution status. Ubuntu is the default Linux distribution in WSL. Every time a Windows 10/11 user enables WSL, they get Ubuntu by default. This gives Canonical a massive installation base without users needing to actively choose a distribution .

Microsoft’s continued investment in WSL. Microsoft has steadily shipped improvements — including better GPU support, systemd integration, and deeper Windows interop — which further lowers the friction for developers to stay inside WSL rather than dual-booting or running native Linux .

The caveats you need to know

This is a forecast from a Canonical executive, not a verified industry metric . Canonical has not released the raw user numbers, its methodology for counting active users, or a comparable count of native desktop installations. The predicted crossover date — “within months” or “before the end of 2026” — has been reported by multiple outlets, but the exact timing depends on telemetry definitions that have not been published .

It is also important to note that Seager compared Ubuntu under WSL with “native” Ubuntu desktop installations specifically, not server or IoT deployments . The actual crossover point may look different depending on how Canonical defines “user” across these categories.

What this means for the Linux ecosystem

If the forecast holds, the line between Windows and Linux continues to blur. Developers no longer need to choose one OS for their desktop and another for their toolchain. WSL has become a bridge that lets enterprise developers use Linux tools without leaving Windows, and Ubuntu is the distribution that benefits most from that bridge.

The real story is not that Ubuntu is failing on the desktop, but that the definition of “running Ubuntu” has expanded. For Canonical, WSL users are still Ubuntu users. And if Seager is right, there will soon be more of them running Ubuntu on Windows than on Linux itself.
