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.
Rapid revenue expansion underpins the dispersed market-implied odds for Anthropic’s IPO closing market cap, with the company’s run-rate climbing from $47 billion in May 2026 to $65 billion by end-July alongside its first operating profit. The May Series H round at a $965 billion post-money valuation, followed by pre-IPO secondaries marking $1.4–1.6 trillion, has anchored trader expectations around the $1.75–2.25 trillion buckets that currently lead at 16.8–18 percent each. Competitive differentiation rests on Anthropic’s enterprise API share of 32–40 percent—ahead of OpenAI and Google—plus leadership in coding benchmarks and safety positioning, which support premium revenue multiples near 13x forward ARR. An October 2026 filing window and comparisons to SpaceX’s post-IPO path introduce near-term catalysts that could tighten the wide probability distribution as public-market demand and macro risk appetite become clearer.
