The rules

An official announcement from Anthropic that it will IPO under a specific ticker symbol will be sufficient to resolve this market. If a ticker used by Anthropic in a qualifying IPO is a variant of a ticker symbol listed in this market group with additional letters to denote a specific class of shares, it will be considered to be that ticker (e.g. if Anthropic uses a ticker symbol of $ANTH.A or $ANTHA, this market will resolve to $ANTH). If Anthropic announces an IPO with multiple tickers that are not considered the same ticker under the previous rule (i.e. $ANTH.A and $ANTH.B would be considered the same ticker), this market will remain open until Anthropic's first day of public trading

The full rules are on the market's page at Polymarket.

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.
