Every outcome, most likely first

What would move this market

  • Inflation (CPI, PCE) and jobs reports, Fed officials' speeches, the FOMC statement and dot plot, and what bond and futures markets price for rates.
  • 1.8T+ leads 1.5–1.8T by 25 points. Flipping the order would take sustained news, not one headline.

How it resolves

The rules, word for word as Polymarket publishes them:

This market will resolve based on Anthropic's market capitalization at the closing price on its first day of trading. If no IPO occurs by December 31, 2027, 11:59 PM ET, the market will resolve to "No IPO by December 31, 2027". Market capitalization expresses the monetary value of a company’s outstanding shares, stated in its pricing currency. It is calculated as the number of shares outstanding multiplied by the closing share price on the first trading day. If the relevant value falls exactly between two brackets, then this market will resolve to the higher range bracket. Resolution will be based on the primary exchange’s official listing page. In the event that the relevant figure is not displayed, another reliable source will be used. In the event of an interruption in the course of the normal trading session on Anthropic’s first day of trading (e.g., a circuit breaker or half-day), the market will resolve according to the official closing price of the abbreviated session. If no such official closing price is published, the market will resolve according to the next trading day on which an official closing price is published, treating that as the first day of trading for purposes of this market.

How results are settled:
Polymarket markets are typically settled through UMA's optimistic oracle: a result is proposed after the event, can be disputed during a challenge window, and is final once undisputed or decided.

Where do these odds come from?

From the public Polymarket market "Anthropic IPO Closing Market Cap (Middle Brackets)". This page reads its live prices about every 5 minutes and states when each number was taken; PredictRips does not set them. A chance is the midpoint of the best bid and ask when the book is tight, else the last price.

Are prediction market odds accurate?

On heavily traded markets, prices have tracked outcomes reasonably well: events priced near 70% happen roughly 70% of the time. They are a crowd estimate that moves with news, not a forecast, and long shots tend to be overpriced.

Can I bet on this on PredictRips?

Not on one market directly. PredictRips sells packs that each draw 3 random positions from its live pool of Polymarket markets, which can include politics, crypto, sport and macro questions; the odds and pack value are shown before you pay. 18+, and only where it is legal.
