Will Dexcom (DXCM) be the best performing company in the Nasdaq 100 during December 2025?

This market will resolve according to the company in the Nasdaq-100 that achieves the highest performance during December 2025. Performance will be measured as the percentage change in each specified security's price during this market's timeframe, calculated by comparing the closing price for the last official trading day prior to this timeframe (November 28, 2025) to the closing price for the last official trading day within this timeframe (December 31, 2025). All companies that are constituents of the Nasdaq-100 as of market issuance will be eligible for consideration, regardless of whether they are removed before the market's resolution date. Any company added to the index after market creation will not qualify. The primary resolution source will be the “Historical Quotes” page for the specified ticker on Nasdaq at: nasdaq.com. Only closing prices will be used for all calculations; total return measures will not be applied. If multiple specified companies exhibit exactly the same highest performance, the market will resolve to the company whose ticker appears first in alphabetical order. If any unspecified company achieves the highest performance during the relevant period, the market will resolve to “Other”. If either of the relevant trading days are shortened, the official closing price published for that session will be used. If any relevant day lacks a specified closing price, the last valid historical closing price offered by the resolution source will be used. Updates to historical prices displayed after resolution will not be considered.
