The rules, in plain English

This market resolves based on Holtec Nuclear's market cap at the closing price on its first trading day. The IPO is scheduled to price on September 17 (ET). If no IPO happens by October 31, 2026, 11:59 PM ET, the market resolves to "No IPO before November 2026". Market cap is the monetary value of a company's outstanding shares in its pricing currency. It's calculated as total outstanding shares multiplied by the official closing share price of the publicly traded class on the first trading day. If needed to capture total market cap (not just one stock class), the calculation includes all outstanding share classes and applies any conversion ratios to the publicly traded class. Shares with no conversion right are counted at their stated outstanding amount without discount, unless filings say otherwise. Outstanding shares come from official company filings or disclosures (like SEC filings). The closing share price on the first trading day comes from the primary exchange's official listing page. If the value falls exactly between two brackets, this market resolves to the higher range bracket. The primary resolution source is official company filings and the primary exchange's official listing page. Market cap is determined by calculating total outstanding shares times closing price from the first trading day. If trading is interrupted on the first day (like a circuit breaker or half-day), the market resolves using the official closing price of the abbreviated session. If no official closing price is published, the market resolves using the next trading day with an official closing price, treating that as the first trading day.
