Anthropic has become the last major 2026 initial public offering expected by traders on Kalshi after OpenAI delayed its stock market debut.
The shift gives Anthropic greater attention among investors seeking a large artificial intelligence listing. Yet the market signal is a forecast, not confirmation that the company will sell shares this year.
Other prospective issuers have also postponed their plans. Those companies and their reasons were not identified, leaving the wider IPO schedule uncertain.
Kalshi Traders Reassess the IPO Calendar
Kalshi allows participants to trade contracts tied to the outcome of future events. Contract prices often reflect the market’s collective estimate of how likely an event is to occur.
That structure makes Kalshi useful as a real-time measure of expectations. It does not make its forecasts official announcements or guarantees.
Anthropic is now seen on the platform as the last major IPO in 2026. The assessment follows OpenAI’s decision to delay its own planned entry into public markets.
The change places unusual weight on one possible deal. If Anthropic also waits, investors could finish 2026 without a major AI company joining the public market.
OpenAI Delay Changes Investor Expectations
OpenAI’s postponement removes one of the most closely watched potential listings from the near-term calendar. The company’s delay also shows that strong public interest does not ensure an IPO will proceed on schedule.
Companies may postpone listings for several reasons. Common factors include unstable markets, valuation concerns, disclosure demands and a preference for private funding. No specific reason for OpenAI’s delay was provided in the available information.
Anthropic now occupies a distinct position. A listing could give public investors direct exposure to a leading AI developer while creating a new reference point for valuing similar businesses.
However, remaining private may offer the company more control over strategy and spending. Public ownership would bring regular financial reporting, closer scrutiny and pressure to explain how heavy investment may produce future returns.
A Forecast Is Not an IPO Filing
Prediction markets can react faster than formal IPO processes because traders update their positions as new information appears. Their conclusions can also change quickly.
Several steps would provide firmer evidence that an Anthropic offering is moving ahead:
- A formal securities filing or confirmed confidential filing
- The selection of banks to manage the share sale
- Published financial details and risk disclosures
- A proposed valuation, price range and trading date
Without such developments, Kalshi’s view should be read as market sentiment rather than a corporate timetable.
Postponements Point to a Cautious Market
The reported delays by other companies suggest caution extends outside OpenAI. A thinner IPO calendar can limit choices for investors and keep more growth companies in private hands.
Postponements can also affect employees and early backers who expected an IPO to create a path for selling shares. For competing AI firms, fewer public listings mean fewer financial disclosures available for comparison.
Anthropic’s next move will therefore carry meaning outside the company. Proceeding could test public demand for AI shares and establish a valuation benchmark. A delay could signal that even prominent technology companies prefer to wait for better conditions.
For now, Anthropic remains the central 2026 IPO prospect in Kalshi trading, while OpenAI and other possible issuers stand back. Investors will watch for regulatory filings and company statements, since those steps will matter more than prediction-market pricing.
