Polymarket says Anthropic IPO 'multiple times' oversubscribed
Polymarket posted on X on November 11, 2026 that Anthropic's IPO is reportedly 'multiple times' oversubscribed. The AI company behind the Claude models is preparing for what sources describe as one of the largest stock market listings. Traders on the prediction platform have been actively pricing expectations across IPO date, price range, and valuation dimensions. The post had garnered 11,800 views and 85 likes at the time of the screenshot. Anthropic's public debut has become a closely watched market on the platform.
The oversubscription claim gives traders a concrete data point to test against Polymarket's existing valuation and timing contracts. If true, it validates the bullish pricing on Anthropic versus Bitcoin and tightens the IPO date window. If false or overstated, it becomes fodder for the credibility debate Senators Warren and Curtis have forced with their bipartisan demand for internal trading data.
The claim also widens the divergence between Polymarket and Kalshi, where traders recently cut Anthropic IPO odds to 57% after midterm results and an AI sell-off. Retail users entering through media partnerships cannot easily reconcile the two signals. That information gap is exactly what regulators are documenting as they build gambling-lawsuit narratives against event contracts.
