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 market.

If the value published after this scheduled release time is labeled preliminary, it will still determine resolution, and the market will resolve independently of any subsequent revisions, corrections, or retroactive adjustments. 

The market will not resolve based on any preliminary values published before the scheduled release time.

If no data is published by the scheduled release time, or if the NCEI website is temporarily unavailable, this market will remain open until that data is made available. If the relevant data is not made available by the date of the next scheduled publication ET, this market will resolve based on available data for the most recent prior month. If the NCEI website becomes permanently unavailable, this market will resolve using another credible source.

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.

If the FluSurv-NET hospitalization rate for the specified week is not released by 11:59 PM ET on the tenth calendar day following the date of the prior FluView weekly report release, this market will resolve to the lowest bracket.

Note: Only the CDC FluSurv-NET cumulative hospitalization rate per 100,000 population for the specified week will qualify, regardless of estimates, projections, state-level reports, or other influenza surveillance metrics published by the CDC or other sources.

Any prior updates will not be considered finalized.

If this dataset has not been updated to include all relevant events by March 31, 2027, or if the Smithsonian GVP becomes permanently unavailable, this market may resolve based on a consensus of credible scientific sources, including the U.S. Geological Survey (USGS), national or regional volcanic observatories, or credible reporting of a scientific consensus.

Note: Smithsonian Institution Global Volcanism Program databases, which include eruptions that reached the relevant threshold prior to this market’s timeframe (e.g., https://volcano.si.edu/faq/index.cfm?question=eruptionsbyyear&checkyear=2025), will not be considered.
