Key Findings
1. AI Course Explosion
Over 2.7 million enrollments went to AI courses in the past year. One in five new Coursera courses focused on artificial intelligence. Google's Introduction to AI alone attracted 384,000 enrollments — more students than every new course on edX and FutureLearn combined.
2. Free Access Is Shrinking
Of the 250 most popular courses of all time tracked by Class Central, only 172 (69%) remain free or free to audit — down from over 80% in 2022. Coursera has reduced its fully-free course count to approximately 300 (down from 1,600+ in 2020). edX now defaults to paid access for most new courses.
3. Subscription Models Dominate
Eight of the ten major platforms now offer or require subscriptions. The average annual subscription cost across platforms is $262. Only Khan Academy and freeCodeCamp remain entirely free — both are nonprofits.
4. Professional Certificates Are the Growth Engine
Google Career Certificates on Coursera dominate professional education. The Google employer consortium (150+ companies) actively recruits certificate holders. With 70%+ reporting positive career outcomes within 6 months, these certificates represent the best ROI in online learning.
5. University Partnerships Expanding
Harvard's CS50 reached 6.7 million enrollments. MIT OCW offers 2,500+ complete courses. Stanford, Johns Hopkins, and Duke continue expanding their online offerings. The line between free online courses and university education continues to blur.
