The prediction market Polymarket shows a 100% probability that Anthropic will not conduct an initial public offering by the end of June 2026, reflecting a consensus among traders that the AI firm will remain private through that date. The market, which has attracted $331,000 in trading volume, offers no alternative outcome—the only contract available is for the company not to IPO, effectively making the bet a near-certainty for participants. No other prediction platforms, such as Kalshi or Manifold, currently list contracts on this event, limiting cross-platform comparison.
Anthropic, known for its Claude AI models, has not publicly disclosed plans for an IPO, and the market's unanimous expectation aligns with broader industry trends where high-profile AI startups have delayed public listings amid regulatory scrutiny and volatile market conditions. Without specific news headlines driving the probability, the 100% figure likely reflects the lack of any credible signals suggesting a near-term IPO. Traders appear to view the June 2026 deadline as too soon for Anthropic to navigate the complexities of going public, given its focus on research and development rather than immediate shareholder returns.
The absence of a countervailing market—where traders could bet on an IPO occurring—means the Polymarket data should be interpreted with caution. A single-platform, one-sided market can amplify consensus without capturing dissenting views. Still, the $331,000 in volume indicates meaningful engagement, suggesting that informed participants see no realistic path to an IPO within the timeframe.
