Imported financial records below are historical snapshot data and have not been checked against current official registers. ## Anthropic Is Now the Sole Remaining Major AI IPO Candidate for 2026 Anthropic is the last credible major IPO opportunity in the AI sector for 2026, according to prediction market data from Kalshi (source: Kalshi via CNBC, 2026-10-19). OpenAI's decision to delay its public market debut has effectively cleared the field, leaving Anthropic as the singular focal point for investors seeking exposure to large-scale AI companies through public equity markets this calendar year. Multiple other candidates have also postponed their listings, compounding the scarcity of AI IPO supply in 2026. The concentration of IPO anticipation on a single name reflects a broader pattern of delay across the AI industry's most prominent private companies. Kalshi's prediction market positioning of Anthropic as the last major IPO of 2026 (source: Kalshi via CNBC, 2026-10-19) signals that market participants have largely priced out the possibility of additional large AI listings before year-end. For institutional allocators tracking the AI trade, Anthropic's public market timeline has become the defining near-term catalyst. ## OpenAI Delay and Broader Postponement Wave Reshape 2026 IPO Calendar OpenAI's postponement of its public market debut is the proximate cause of Anthropic's elevated IPO significance (source: CNBC, 2026-10-19). The delay is not isolated: other high-profile AI and technology companies have similarly pushed back their listing timelines, creating a compressed and increasingly Anthropic-centric IPO narrative for the remainder of 2026. This wave of postponements has materially reduced the number of major AI IPO events available to public market investors within the current year. ## Key Metrics and Source Transparency The table below summarizes the factual record as provided in the source material.
