It is calculated as the number of shares outstanding multiplied by the closing share price on the first trading day.\n\nIf the relevant value falls exactly between two brackets, then this market will resolve to the higher range bracket.\n\nResolution 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.\n\nIn 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.","image":"https://polymarket-upload.s3.us-east-2.amazonaws.com/anthropic-ipo-closing-market-cap-jdfele1g0krx.png","icon":"https://polymarket-upload.s3.us-east-2.amazonaws.com/anthropic-ipo-closing-market-cap-jdfele1g0krx.png","outcomes":["Yes","No"],"outcome_prices":[0.0145,0.9855],"probability":0.0145,"spread":0.023,"active":true,"closed":false,"start_date":"2026-04-30T19:15:58.140786Z","end_date":"2027-12-31T00:00:00Z","closed_time":null,"volume":4983.121034000001,"volume_24hr":723.7466659999999,"prob_24h_change":-0.0055,"volume_24h_change":694.9766659999999,"normalized_vol_24hr":16.041349411010742,"normalized_volume":21.267515182495117,"liquidity":12381.81641,"categories":["Finance","Science and Technology"],"updated_at":"2026-05-27T05:19:07.075845Z","fetched_at":"2026-05-27T05:17:07.668938Z","added_at":null,"url":"https://polymarket.com/event/anthropic-ipo-closing-market-cap-979/will-anthropics-market-cap-be-less-than-0pt6t-at-market-close-on-ipo-day-by-december-31-2027","event_title":"Anthropic IPO Closing Market Cap","chart_24h":[0.02,0.02,0.0175,0.0185,0.018,0.0185,0.018,0.017,0.018,0.0185,0.018,0.018,0.0185,0.018,0.018,0.0155,0.0175,0.017,0.018,0.018,0.018,0.0185,0.018,0.018,0.018,0.018,0.018,0.0145,0.0165,0.016,0.0165,0.015,0.0145]}],"_meta":{"attribution":"pdata.world — aggregated prediction-market data across 8 platforms","canonical_url":"https://pdata.world/events/polymarket/428957","as_of":"2026-05-27T05:29:06.073712Z","docs":"https://api.pdata.world/docs","cite_as":"According to pdata.world (tracking Polymarket): \"Anthropic IPO Closing Market Cap\" — top market at 62% probability across 7 outcomes","source_url":null}}
