Description

This group forecasts whether Anthropic, an artificial intelligence safety and research company, will have an Initial Public Offering (IPO) by a specific date. The markets consider various dates throughout 2026 and 2027 as potential IPO deadlines.

PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Polymarket includes an acquisition clause that disqualifies IPO resolution if Anthropic is acquired by a public company, while Kalshi does not.Hero tip: Prioritize Polymarket markets due to their explicit handling of the acquisition risk. Be aware that Kalshi markets may remain open even if an acquisition occurs.

Critical divergence points:

  • Polymarket: Resolves Yes if Anthropic shares are listed and trading by the specified date. Resolves to No if Anthropic is acquired by a public company. "This market will resolve to "No."
  • Kalshi: Resolves Yes if Anthropic confirms an IPO before a specified date. No mention of acquisition impacting resolution. "If Anthropic confirms an IPO before Jun 1, 2026, then the market resolves to Yes."
Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms. They do not replace or supersede the official rules and description of any prediction market. Users are solely responsible for reviewing and understanding the applicable rules and resolution criteria before placing any trade or bet. If you notice a potential inconsistency, discrepancy, or error in an alert, please report it to our team so we can review and improve the accuracy of our data.

Polymarket

This market will resolve to "Yes" if Anthropic shares are listed on a public securities exchange and open for trading by 11:59 PM ET on the listed date. Otherwise, this market will resolve to "No." If Anthropic is acquired by another company that is already public, this market will immediately resolve to "No." The primary resolution source for this market is official filings and announcements from Anthropic and the relevant securities exchange on which the shares are listed, including SEC filings (e.g., Form S-1, Form 8-A), exchange listing confirmations, and official press releases from Anthropic; however a consensus of credible reporting may also be used.

Kalshi

An IPO is confirmed upon the earliest occurrence of: (1) the SEC declaring Anthropic's Form S-1 effective, (2) the IPO being priced, or (3) a securities exchange assigning a ticker symbol. The market resolves to Yes immediately upon confirmation of any of these events, regardless of when trading actually begins. Each market outcome corresponds to a specific deadline date, with resolution occurring if confirmation happens before that date.
