Anthropic’s confidential S-1 filing and accelerating IPO timeline—now targeting a late-September prospectus and mid-October marketing ahead of a potential November listing—drive trader sentiment on its eventual ticker. With no symbol disclosed, market-implied odds favor $ANTH at 43% as the most straightforward abbreviation of the company name, consistent with precedents for high-profile tech listings, ahead of $ANT at 31.6%. Shorter or more stylized alternatives like $AAI trail due to lower alignment with naming conventions. The pending public filing and finalization of a $15 billion credit facility represent the next key catalysts that could clarify or shift these probabilities before the shares begin trading on Nasdaq.

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 and will resolve according to the ticker symbolizing the security class with the greatest market capitalization. Market capitalization is calculated as the number of shares outstanding multiplied by the closing share price on the first trading day. If this also results in a tie, this market will resolve according to the ticker symbol that comes first in alphabetical order.
If Anthropic IPOs with a non-listed ticker, or does not IPO or officially announce an IPO and ticker symbol by December 31, 2027, 11:59 PM ET, this market will resolve to "Other."
The primary resolution source for this market will be official information from Anthropic and the primary exchange's official listing page. In the event that the relevant figure is not displayed, another reliable source will be used.
Note: 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 use the official closing price of the abbreviated session. If no such official closing price is published, the market will use the closing price on the next trading day for which an official closing price is published, treating that as the first day of trading for purposes of this market.
