It is not an estimate by MarketClaims. ## The question, as the venue words it Will Anthropic have the highest IPO Market Cap 2026? ## How this market settles This market will resolve to the company that achieves the highest market capitalization in U.S. dollars based on the official closing price on its first trading day in 2026. This market will resolve to a company that completes an Initial Public Offering (IPO) between January 1 and December 31, 2026, 11:59 PM ET. Market capitalization is defined as the total number of outstanding shares multiplied by the closing share price on the first trading day. If two or more companies have exactly equal highest closing market capitalizations, this market will resolve to the company whose listed name comes first alphabetically. 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 case the respective company's primary exchange’s official listing page does not report in U.S. dollars, it will be converted to U.S. dollars using the U.S. Federal Reserve Board’s H.10 foreign exchange reference rate for the relevant currency pair on the company’s first trading day (https://www.federalreserve.gov/releases/h10/). If no such rate is available for the relevant trading day, the most recent previously published rate will be used. If the relevant currency is not listed, another credible exchange rate source will be used. A listed company may resolve to "No" as soon as it becomes unable to complete an IPO, including due to acquisition, merger, or absorption by an entity that is already publicly traded. In the event of an interruption in the course of the normal trading session on the respective companies’ 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 ma ## Evidence you can inspect _These labels describe how a claim relates to the question.

No individual review. It rests on 30 claims from 13 publishers; anything not reported in those sources is not represented here. The report recorded 4 resolution risks, listed with this brief. - The market description lists the official resolution source as the Federal Reserve H.10 page (a currency exchange rate source), which is inconsistent with resolving market capitalization — the primary exchange listing page is described as the main source, creating ambiguity about the true authoritative source. - No definition is provided for 'outstanding shares' — whether this includes all share classes, locked-up shares, or only the public float is unspecified, which could affect market cap calculations. - 'Another reliable source' is undefined for cases where the primary exchange listing page does not display the figure, leaving room for subjective interpretation. - If Anthropic does not IPO but no other company achieves a highest IPO market cap, the resolution outcome for this specific option is not fully addressed. ## Publication history - Published 12 November 2026; research dated 12 November 2026. ## Since the previous brief This is the first published brief for this event.
