Cursor edges out pure-play AI companies through architectural depth, not market reach. Its 100/100 reflects that AI isn't bolted onto its product—it's the foundation—while Perplexity (99) and Anthropic (97) score fractionally lower despite larger market presence because they face infrastructure or scaling constraints. The real gap: Cursor's AI Infrastructure (95) barely trails despite being smallest, suggesting its engineering is disproportionately efficient compared to Perplexity's broader inference demands and Anthropic's foundational model costs.
