Polymarket traders are pricing a 66% probability that Anthropic closes its first trading day above a $2 trillion market cap, according to a contract on the prediction market platform.

Shows Polymarket being used to price high-stakes private tech IPO outcomes, a category that could draw institutional interest if the contract resolves accurately.
