Analyst take: what the data says about ChatGPT vs Perplexity
ChatGPT has the clearer adoption lead as of August 2026, ranking #2 overall compared with Perplexity at #49. Perplexity is closing the gap: it climbed 49 positions, while ChatGPT dropped 1 position. By spend, ChatGPT ranks higher (#6 versus #182), which shows where more of the measured software budget currently sits. The switching signal adds useful context: after leaving ChatGPT, some companies adopted Claude or ChatGPT. The practical takeaway is to separate market position from product fit: the rankings show which tool is more established and where buying momentum is moving, but they do not measure features, price, or quality. Use those signals to build a shortlist, then decide against your own workflows and requirements.
