The rules

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 n

Reading the odds

A prediction market trades contracts that pay $1 if something happens. Its price is the market's chance: a contract at 62¢ means traders give it 62%. Each number here is the midpoint between the best bid and offer, or the last trade when they are more than ten cents apart.

For a question with many answers (who wins, which range a number lands in), the chances are scaled to add up to 100%. A price ladder ("above 4.25%, above 4.50% ...") gives a whole distribution: its median is where traders see an even chance either way.

Kalshi is a U.S. exchange regulated by the CFTC; its money is counted in contracts, shown here as dollars at their price. Polymarket counts dollars. ForecastEx is Interactive Brokers' exchange, regulated by the CFTC; its contracts too are shown as dollars at their price. Crypto.com lists its markets on Crypto.com | Derivatives North America, a U.S. exchange regulated by the CFTC; it reports the dollars traded. Where more than one asks the same question, each is shown, never averaged.

Prefer betting odds? Switch to American (+150) or decimal (2.50) odds at the top of the page.
