In August 2026, the TIOBE Index revealed the top 10 most popular programming languages, with Python maintaining its No. 1 position at 18.53%, followed by C, C++, Java, C#, and JavaScript in descending order. Rust held onto its No. 10 spot, with its rating increasing from 1.34% in July to 1.45% in August after entering the ranking for the first time in July. C rose slightly from 10.86% to 11.10%, while C++ experienced a decline from 9.12% to 8.62%.
MATLAB, however, dropped out of the top 20 for the first time in over a decade, slipping to No. 25. The decline in MATLAB's popularity is attributed to its paid licensing model and slower evolution compared to other languages such as Python, C++, and Rust. TIOBE CEO Paul Jansen explained that the index is not a measure of the "best" programming language or the most code written, but rather reflects the popularity among professional programmers, programming courses, and third-party vendors.
