Dario Amodei, co-founder and chief executive officer of Anthropic, during an interview on "The Circuit with Emily Chang" at Anthropic's headquarters in San Francisco, California, US, on Thursday, April 30, 2026.

Kalshi traders see greater odds that Anthropic will announce an initial public offering this year after several news outlets reported that the company plans to warn investors in its IPO prospectus that its models are dangerous.

Chances that the AI company announces an initial public offering before November jumped from 4.7% on Sept. 28 to 16% Wednesday afternoon.

Kalshi traders see a greater than 60% chance an IPO is announced before December and nearly 80% likelihood that it happens before January. The contract asks when the company will announce an IPO and will be verified from news outlets and the company itself, according to Kalshi website.
