Linux has achieved a new milestone in the United States, surpassing the 5% desktop operating system market share mark for the first time. The operating system currently accounts for 5.03% of the U.S. desktop market, marking an important milestone in the evolution of open source computing.
According to StatCounter's June 2025 global statistics, Windows is still the absolute leader, accounting for 63.2% of the market, but its market share has been steadily declining, falling by nearly 13 percentage points over the past decade. Apple's market share is composed of OS X (16.57%) and macOS (7.72%), which together account for nearly 24%. The "unknown" operating system category accounts for 4.76%, while Chrome OS accounts for 2.71% of the desktop ecosystem.
Linux's growth of more than 5 percent means it has surpassed the "unknown" category for the first time, a symbolic threshold for the open source community and advocates who have long pushed for broader adoption. This trend points to a growing interest among U.S. computer users in finding alternatives to mainstream platforms.
Linux's resurgence is driven by a variety of factors. One notable factor is user dissatisfaction with the Microsoft ecosystem. The impending retirement of Windows 10 is prompting users of older hardware to reconsider upgrading, as Windows 11 requirements often require the purchase of a new system. Additionally, ongoing privacy concerns, forced system updates, adware, and Microsoft's approach to AI data collection have prompted many to explore open source platforms.
The gaming industry has also fueled Linux's boom. The popularity of Valve's Steam Deck, a console based on the Linux operating system, has brought the flexibility and customizability of Linux to a new generation of gamers, broadening the platform's appeal beyond traditional tech-savvy users.
The development of Linux has made its popularity continue to grow. Distros like Ubuntu and Linux Mint have made significant improvements in ease of use in recent years, lowering the barrier to entry for non-technical users to set up and maintain systems. Open source's ideas of privacy and control continue to gain traction, while modern and efficient Linux distributions are breathing new life into older computers. Linux's compatibility with a variety of applications has also been improved with the help of projects like Wine and expanded hardware support.
There is also discussion within the community that Linux's actual market share may be underestimated. Many privacy-conscious Linux users take steps such as changing their user agent or blocking website trackers so that they are not visible in metrics that rely on web analytics. 4.76% of the systems in StatCounter's report are classified as "unknown," meaning that some of these devices may be running Linux but not detected.
Open source enthusiasts also highlight the relationship between Linux and Chrome OS. Google's Chrome OS, built on the Linux kernel, holds 2.71% of the market share. Combined, their market share (sometimes referred to as the "Linux family") reaches 7.74%, further underscoring the growing influence of Linux derivatives in the U.S. desktop market.
Linux's trajectory has been one of slow start and steady acceleration. Data shows that it took Linux eight years to increase its market share from 1% to 2% in April 2021. However, in just over three years, its market share has quadrupled to 5%.
