Polymarket Bettors Predict Anthropic Will Be Largest Private Company by August

Polymarket · x · 2026-08-02

Prediction market Polymarket has launched a contract on which company will be the largest private firm by the end of August. Current odds heavily favor Anthropic, with a 96% implied probability of taking the top spot.

In contrast, OpenAI sits at just 3%, while Perplexity and Anduril trail at 1.5% and 1.4% respectively. This market sentiment strongly implies that traders expect current giants like OpenAI or Stripe to IPO before the deadline, leaving Anthropic as the most valuable private company.
