Why this matters:
This 24% probability reflects market expectations that Robert F. Kennedy Jr. will make specific statements during a Health Subcommittee appearance. The current level suggests markets view such testimony as somewhat unlikely in the near term, though the threshold remains meaningful. RFK Jr.'s position as HHS Secretary and his scheduled congressional appearances are primary drivers—confirmation of a subcommittee hearing would increase the probability, while the expiration of his tenure without testimony would decrease it. The key uncertainty centers on what constitutes relevant remarks: markets must determine whether routine responses about policy positions count, or if only controversial or novel statements qualify. The most immediate catalyst would be announcement of an actual Health Subcommittee hearing involving RFK Jr., which would force price discovery as traders assess his likely testimony topics.

Key factors:
- RFK Jr.'s HHS Secretary tenure status and scheduled congressional appearances remain the primary determinant of whether such testimony occurs at all
- The contract definition must specify what qualifies as 'saying' particular content—routine policy responses versus novel or contentious statements create significant interpretation risk
- Historical RFK Jr. statements on vaccine safety, public health authority, and regulatory reform suggest predictable testimony themes that markets could model
- No confirmed Health Subcommittee hearing with RFK Jr. appears currently scheduled, making the 24% probability conditional on future legislative action
- The contract's resolution depends on timestamped records of his remarks, introducing a factual verification requirement distinct from subjective interpretation

## Methodology

SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged. Snapshots refresh every 5 minutes during market hours.
