Anthropic, the AI safety company behind Claude, is expected to pursue a public offering by the end of 2027. These six related prediction markets aggregate collective forecasts of where Anthropic's valuation will settle on its IPO day. Rather than offering a single outcome prediction, this event groups markets that partition Anthropic's possible market cap across distinct valuation bands, allowing observers and traders to express granular views about the company's likely position within the broader AI market landscape. The probabilities across these markets reflect real-time consensus about Anthropic's future value based on its current trajectory in large language models, enterprise partnerships, research breakthroughs, and competitive positioning relative to other leading AI companies. Reading the prices across these bands tells a story: if probabilities are higher for lower valuations, market participants expect a more modest IPO; if they're concentrated in middle bands, consensus leans toward a substantial but not stratospheric valuation; if upper-band prices are elevated, the market anticipates a mega-cap debut. By tracking these probabilities together, you can identify where the aggregate forecast is concentrating—whether the market believes Anthropic will join the elite tier of tech mega-caps or settle at a more measured valuation. The markets expire on the first trading day after Anthropic's public offering, making these forecasts a useful real-time barometer of investor sentiment as the company moves toward its eventual IPO.
