May belongs to ChatGPT's comeback story. After 3 months of share erosion, it surged back to 84.7% AI share, recovering nearly all of what it had lost since February. Gemini gave back most of its March to April gains, dropping from 13.2% to 9.2% in a single month. Claude slipped modestly from 3.6% to 2.8% but remains well above its pre-March baseline, suggesting its acceleration was structural, not seasonal. Perplexity continued its quiet fade to 3.3%.

Perplexity, meanwhile, keeps shrinking, down 0.9 points and at its fewest visitors ever in our data.
