Anthropic Leads 2026 IPO Odds on Kalshi Market

Live Poll

Do you trust market betting odds to accurately predict when a private company will go public?

Anthropic now holds 75% market odds for a formal 2026 IPO announcement on the Kalshi prediction platform. This follows the company's confidential prospectus filing with the SEC in June and substantial third-quarter revenue.

Why it matters

The odds reflect investor sentiment regarding upcoming public offerings, a sector currently facing a 33% decline in priced U.S. IPOs compared to 2025. Traders track these milestones using criteria such as effective SEC Form S-1 filings, priced offerings, or assigned tickers.

Anthropic generated $16.8 billion in revenue during the third quarter. U.S. IPOs priced in 2026 are currently down 33% from 2025 levels.

The players

Anthropic

This artificial intelligence company has gained significant market interest following a strong third-quarter revenue report.

Sam Altman

He is the chief executive officer of OpenAI who publicly stated in September that his company would not pursue an IPO in 2026.

OpenAI

This AI research and deployment organization currently maintains a 3% probability for a 2026 IPO on prediction markets.

The details

Traders on the Kalshi platform use binary contracts to wager on which companies will meet formal IPO requirements by the end of 2026. While Anthropic has high confidence, other major firms show lower expectations, with Plaid at 10%, Deel at 3%, and Databricks at 1%.

June 2026: Anthropic filed a confidential prospectus with the SEC.
September 2026: Sam Altman ruled out an OpenAI public offering for 2026.
October 19, 2026: Anthropic reached 75% market odds for an IPO announcement.

Macro View

The current 33% decline in U.S. IPOs versus the 2025 IPO market volume provides a baseline for evaluating the cooling interest in public listings. This trend highlights a stark divergence from prior years where firms like Plaid and Databricks were seen as high-probability candidates.

The potential IPO of major technology firms could signal a shift in market liquidity and investment opportunities for retail portfolios. Investors should monitor how these valuation expectations align with broader volatility in the U.S. financial sector.

The takeaway

Predictive markets serve as a barometer for investor confidence in private companies preparing for public entry. Readers should note that these odds are speculative and can shift significantly as companies finalize their SEC filings.
