Anthropic IPO by 2027?

Market context

Anthropic, the AI safety-focused research company founded in 2021, has not yet filed for a public listing or announced concrete IPO plans as of early 2025. The market settles on 1 July 2027, giving a roughly two-and-a-half-year window for the company to move from private funding rounds to public markets. Anthropic has raised over $7 billion in private capital from investors including Google, Salesforce Ventures, and others, but remains privately held with no disclosed timeline for going public.

Recent precedent from comparable deep-tech founders offers mixed signals. OpenAI has similarly resisted IPO pressure despite substantial private valuations, whilst other large AI infrastructure companies like Databricks and Scale AI remain private well beyond traditional venture maturity windows. Conversely, companies in the generative AI space that have gone public—such as Nvidia and Palantir—did so through either organic growth trajectories or SPAC mergers rather than traditional IPOs. The 0% crowd probability across Polymarket reflects genuine uncertainty: no regulatory filing has emerged, no underwriter has been named, and the company has made no public commitment to a specific listing date.

Traders monitoring this market should track Anthropic's quarterly funding announcements, executive statements on capital structure, and any SEC filing activity. Recent reporting from The Information and Bloomberg has covered the company's scaling operations and revenue growth, but neither has suggested imminent IPO preparation. The distinction between platforms matters here: Polymarket's decimal odds format (currently reflecting near-zero probability) differs from Kalshi's implied-probability display, though both charge similar taker fees. Settlement hinges on official exchange listing confirmation, not valuation milestones or funding rounds, making the binary outcome relatively clean despite the long timeframe.

Methodology

This page compares Anthropic IPO by 2027? specifically across Polymarket, Kalshi, Betfair Exchange and Smarkets. Live odds come from the Polymarket order book; the other venues' contract details are maintained manually because their APIs aren't directly comparable. Every CTA routes to Polymarket Alternative, which mirrors the Polymarket order book at 0% fees.

Resolution & payout

Settlement is the biggest difference between the four platforms: Polymarket on-chain in USDC (instant), Kalshi USD via CFTC (T+1), Betfair and Smarkets in local currency via bank withdrawal (T+1 to T+3). Polymarket Alternative routes every trade directly into Polymarket's on-chain settlement, which is why payouts land fastest.
