Evidence context
Recent reports indicate that Anthropic has confidentially filed for an IPO, with executives hinting at a possible listing in 2027, and valuation discussions range from approximately $1.8 trillion to $3 trillion. The company reported first-half 2026 revenue of about $16.3 billion, with an annualized run rate of roughly $65 billion; at a $2 trillion valuation, this implies a price-to-sales ratio of about 30.8x, well above peers like Snowflake. Bullish arguments suggest that if 2028 revenue reaches $190-200 billion, the forward P/S ratio at a $2 trillion valuation would be only 10x. However, these reports do not provide a clear probabilistic basis for the IPO's first-day market cap falling in the $2.0-2.25 trillion range by 2028, leaving the reasonableness of the prediction-market probability dependent on future revenue growth materializing.
Related facts and sources
Anthropic has confidentially filed for an IPO, with executives hinting at a possible 2027 listing, and valuation discussions range from $1.8T to $3T, which makes a pre-2028 IPO plausible but does not specify the first-day market cap.
First-half 2026 revenue was about $16.3B, with an annualized run rate of roughly $65B; at a $2T valuation, the P/S ratio is about 30.8x, higher than peers like Snowflake, indicating a rich current valuation.
Bullish arguments suggest that if 2028 revenue reaches $190-200B, the forward P/S ratio at a $2T valuation would be only 10x, but this projection is not yet confirmed.
Earlier updates
- — Public tracking started; no independent probability estimate yet.; Starting public context: 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.
- — The most likely outcome is "No", with a our assessmentestimate of 67%.; As of October 2026, multiple reports state that Anthropic plans to go public at a valuation of around $2 trillion, but timelines vary: one report says the IPO was originally planned for October and moved to November around Thanksgiving, while others do not specify a date. Reports also note that a $2 trillion valuation implies a price-to-sales ratio of about 30.8x based on $65 billion annualized revenue, far above comparable companies like Snowflake and Nvidia, but supporters argue that if 2028 revenue reaches $190-200 billion, the forward P/S would be only 10x. These reports rely on industry sources and speculation, lacking official confirmation or detailed financials, so they cannot establish whether the first-day market cap will fall within the $2.00-2.25 trillion range.
- — The most likely outcome is "No", with a our assessmentestimate of 56%.; As of October 2026, multiple reports discuss Anthropic's IPO valuation, citing a range of roughly $1.8 trillion to $3 trillion, and highlight 2025 revenue of about $4.6 billion (up nearly 12x year-over-year) and H1 2026 revenue of about $16.3 billion (3.5x full-year 2025) as bullish factors. However, these reports do not confirm that Anthropic has formally filed for an IPO or set a listing date, nor do they provide an official source for 2028 revenue projections. Thus, the evidence shows market debate and divergence on valuation, but does not directly establish whether the probability of a first-day IPO market cap between $2 trillion and $2.25 trillion by 2028 is reasonable. The key uncertainty lies in whether future revenue growth materializes and whether the IPO occurs as anticipated.
