Cloudflare's 0.47% Slide and 173rd-Ranked $630M Volume in AI Bot Management Dispute with Perplexity

Cloudflare (NET) fell 0.47% on August 5, 2025, with a trading volume of $630 million, ranking 173rd in market activity. The stock’s decline came amid heightened scrutiny over its dispute with AI startup Perplexity, which has sparked debates about ethical AI training practices and bot management strategies.

Cloudflare accused Perplexity of evading website restrictions by using stealth crawlers to bypass robots.txt protocols and web application firewall (WAF) rules. The CDN provider reported that Perplexity’s crawlers impersonated Chrome browsers on macOS and rotated through unlisted IP addresses and autonomous system numbers (ASNs) to access content despite explicit bans. Cloudflare emphasized that this behavior violates longstanding internet norms, undermining trust in automated data collection practices.

To address the issue, Cloudflare introduced new tools to block Perplexity’s stealth crawlers, including heuristic updates to its managed rules and a Pay Per Crawl program allowing publishers to monetize AI data scraping. The company also highlighted that OpenAI adheres to robots.txt guidelines, contrasting its approach with Perplexity’s tactics. The controversy raises broader questions about AI data sourcing and the legal risks of unauthorized content aggregation.

Perplexity denied the allegations, calling Cloudflare’s claims technically flawed and accusing the CDN of overreaching in bot management. The dispute reflects growing tensions between AI developers seeking training data and content providers seeking to protect intellectual property, with potential regulatory and market implications for both sectors.
