This market concerns the percentage of U.S. adults age 18–29 whom Gallup reports as identifying as bisexual, based on Gallup interviews conducted during calendar year 2026.

Gallup's corresponding 2025 estimate was 16.1%.

The market resolves from Gallup's published “Bisexual” percentage in the 18–29 age row, or an exactly equivalent official Gallup statistic explicitly referring to the same calendar-year pooled data and exact age group.

Gallup allows respondents to select multiple LGBTQ+ identities. Accordingly, this market measures the percentage selecting “bisexual”; it does not require bisexual to be the respondent's exclusive identity. The market does not resolve from Gallup's percentage of LGBTQ+ respondents who are bisexual. It requires the percentage of all U.S. adults age 18–29 who select bisexual. A Gen Z estimate will not substitute for an 18–29 estimate. A result for women age 18–29 alone will not substitute for the entire 18–29 group.

If Gallup publishes Total LGBTQ+ for 18–29 but does not publish bisexual identification for that same age group, the market resolves N/A. If Gallup changes the identity categories such that “bisexual” is no longer separately reported on a reasonably comparable basis, the market resolves N/A.
