## About

The Underlying is the United States’ percentage share of World gross domestic product in current U.S. dollars for 2026, calculated using the World Bank’s World Development Indicators.

The Expiration Value will be calculated as: 100 × United States GDP ÷ World GDP

“United States GDP” and “World GDP” refer to the values attributed to 2026 for the World Bank indicator “GDP (current US$),” series code NY.GDP.MKTP.CD, for the economies United States and World, respectively.

Both inputs must be taken from the first World Development Indicators database release in which values attributed to 2026 are available for both the United States and World.
