About This Event
This market will resolve based on the date, in Eastern Time, that Anthropic launches its Initial Public Offering (IPO). An IPO refers to the first public sale of shares by the listed company on a recognized stock exchange. If no IPO occurs by November 30, 2026, 11:59 PM ET, the market will resolve to "No IPO by November 30, 2026". The primary resolution source for this market will be the official listing page of the relevant exchange; however, a consensus of credible reporting may also be used.

What the contract measures
The supplied event is "Anthropic IPO Date" on Polymarket. Its rules state that it "will resolve based on the date, in Eastern Time, that Anthropic launches its Initial Public Offering (IPO)" [1]. The rules define an IPO as "the first public sale of shares by the listed company on a recognized stock exchange" [1]. If no IPO occurs by November 30, 2026, 11:59 PM ET, the market resolves to "No IPO by November 30, 2026" [1].
The event contains twelve separate contracts, and they are not worded identically. Most ask whether the IPO occurs on one specific date, such as "Will Anthropic IPO on November 18, 2026?" Two are cumulative or threshold-style: "Will Anthropic IPO on November 13, 2026 or earlier?" and "Will Anthropic not IPO by November 30, 2026?" Each contract has its own listed end time. For example, the November 18 contract lists an end date of 2026-11-19T04:59:00Z, which corresponds to 11:59 PM ET on November 18. These listed end times are contract data, not a confirmed IPO date.
Reading the snapshot
The provider observed these prices at 2026-10-27T03:00:06Z, and the record was retrieved at 2026-10-27T03:11:59Z [1]. These are snapshot prices from that moment. They are not executable quotes, and they are not verified probabilities.
The saved sample includes all twelve markets for this event, so the sample is complete for the saved provider event. The Yes prices range from 0.06 for the November 23 contract to 0.22 for the November 18 contract. The "November 30" and "not IPO by November 30" contracts are separate listings with different wording and different prices (0.105 and 0.15 Yes), so they should not be treated as the same question.
Individual date contracts should not be summed or averaged to infer a combined view. The sample warning states that including all saved markets "does not establish that the providers list every possible real-world outcome" [1]. Differences in price between contracts reflect different wording and close times, and they do not by themselves indicate an arbitrage opportunity.
What remains uncertain
The supplied evidence does not explain why any price is where it is, and it does not show trading volume, liquidity, or the number of traders. It contains no reporting on Anthropic's IPO plans beyond the contract rules. Whether an IPO occurs, and on what date, is not established by this record.

Saved Oct 27, 2026 UTCOverview
The Anthropic IPO Date contract is a Polymarket event that asks when Anthropic will launch its initial public offering. Under the contract rules, the market resolves based on the date, in Eastern Time, that Anthropic launches its IPO [1]. The rules define an IPO as the first public sale of shares by the listed company on a recognized stock exchange [1]. The contract includes a fallback. If no IPO occurs by November 30, 2026, at 11:59 PM ET, the market resolves to "No IPO by November 30, 2026" [1]. The rules name the official listing page of the relevant exchange as the primary resolution source, but state that a consensus of credible reporting may also be used [1]. The November 30, 2026 date is a deadline written into the contract rules. It is not an announced IPO date, and the supplied evidence does not show that Anthropic has scheduled an offering. The saved event contains twelve date-specific markets. Each asks whether Anthropic will IPO on a particular date, or whether it will IPO on or before a given date, or whether it will not IPO by November 30, 2026 [1]. Each market has a Yes and a No outcome with a recorded price. Because these are separate markets with different end dates, their prices should not be read as a single ranked forecast. Each price is a recorded snapshot from the Polymarket event data, not an executable quote, and the volume figures in the provider data do not measure liquidity or the number of traders.
Historical Context
Anthropic was founded in 2021 by Dario Amodei and his sister Daniela Amodei [3]. The company is behind the large language model series Claude [3]. Before founding Anthropic, Dario Amodei was vice president of research at OpenAI [3]. A Wikipedia summary retrieved for this article states that Anthropic was valued at US$965 billion as of May 2026 and is one of the most valuable AI pure play companies, rivaled by OpenAI [3]. That figure is a historical reference from that summary and does not describe Anthropic's status on the date of this article.
Why It Matters
The contract measures timing rather than whether an IPO will eventually happen. Its rules specify that the IPO must be a first public sale of shares on a recognized stock exchange [1]. A launch that does not meet that definition would not satisfy the contract as written, so the wording of the definition matters as much as the date. The primary resolution source is the official listing page of the relevant exchange, with credible reporting as a secondary basis [1]. Traders following the contract would therefore need to track how the exchange and reporting describe any offering, rather than relying on announcements alone. The contract also has a listed end time that falls shortly after the November 30 deadline, which reflects the platform's closing schedule rather than an event date [1].
Snapshot context

Market descriptions and listed closing times define the contracts; they do not establish that the real-world outcome has occurred. This article does not include a separately verified news update. [1]
