Background

Senator Chuck Grassley (R-Iowa) was born on September 17, 1933, making him 91 years old as of 2025. He is currently one of the oldest serving members of the United States Senate. Grassley has served in the Senate since 1981 and has maintained an active role in politics despite his advanced age.

Resolution Criteria

This market will resolve as YES if Chuck Grassley is alive at any point during the calendar year 2026 (January 1, 2026, through December 31, 2026).

The market will resolve as NO if:

• Grassley passes away before January 1, 2026

• Official confirmation of his death is announced by reliable sources such as his office, family, or major news outlets

If there is uncertainty about Grassley's status (e.g., he is missing with no confirmation of death or life), resolution may be delayed until his status is confirmed.

Considerations

Life expectancy predictions involve significant uncertainty. While the average life expectancy for American males is lower than Grassley's current age, many individuals live well into their 90s and beyond. Grassley has demonstrated remarkable longevity and continued to maintain an active schedule in the Senate despite his age.
