This market will resolve based on SpaceX's market capitalization at the closing price on its first day of trading.

If no SpaceX IPO occurs by December 31, 2027, 11:59 PM ET, the market will resolve to "No IPO before 2028".

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 SpaceX’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.

ECDSA.fail tracks an open challenge to outperform Google’s quantum circuit benchmark for ECDSA-style elliptic-curve cryptography. Its official challenge site at www.ecdsa.fail/ measures progress based on the product of a circuit’s qubits and Toffoli gates and displays a headline metric such as “[x]% ahead of Google’s classified circuit.”

This market will resolve to "Yes" if ECDSA.fail reports progress equal to or higher than the specified percentage ahead of the fixed Google reference point at any point by June 30, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No".

For purposes of this market, the Google reference point is fixed at 2,992,500,000, calculated as 2.1M Toffoli gates × 1,425 qubits, as shown on ECDSA.fail and corresponding to Google’s private low-gate Pareto point in the official ECDSA.fail challenge repository (https://github.com/ecdsafail/ecdsafail-challenge/blob/main/README.md). This fixed reference point will be used regardless of whether ECDSA.fail, Google, or any other source later updates, replaces, or redefines the Google reference benchmark.

If ECDSA.fail no longer reports progress as a percentage ahead of the fixed Google reference point, resolution will be based on the best valid score shown by ECDSA.fail or officially confirmed by the challenge organizers before the resolution time, converted into a percentage improvement relative to the fixed Google reference point.

Local runs, forks, pull requests, screenshots, or manually edited repository files will not qualify unless the result is reflected on the official ECDSA.fail challenge site or otherwise confirmed by the challenge organizers.

The primary resolution source for this market will be the official ECDSA.fail challenge site (https://www.ecdsa.fail/). Official statements from the challenge organizers may also be used.

For the purposes of this market, a Category 4 hurricane is a hurricane with maximum sustained winds of 130-156 mph, as described at https://www.nhc.noaa.gov/aboutsshws.php, and a hurricane landfall is said to occur when the hurricane's surface center intersects with the coastline, as described at https://www.nhc.noaa.gov/aboutgloss.shtml#LANDFALL. 

This market will resolve to "Yes" if any storm makes landfall in the conterminous United States as a Category 4 hurricane, as reported in official National Hurricane Center advisories (https://www.nhc.noaa.gov/archive/2023/IDALIA.shtml?) between market creation and December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”.

This market may resolve based on the initial advisory released by the NHC for whether any storm has made landfall in the conterminous United States at Category 4 strength, regardless of any later retraction or analysis that may contradict the initial qualifying announcement. However, subsequent corrections or updates will be considered if they indicate a qualifying incident.
