Why this matters:
This market reflects an estimated 32% chance that Byron Donalds will secure the Republican nomination for Florida Governor. Donalds, a U.S. Congressman, enters a field where other candidates like James Fishback are also competing for the nomination. The probability reflects uncertainty about candidate viability, fundraising capacity, primary endorsements, and voter preference in Florida's Republican primary electorate. Key factors include whether Donalds can differentiate himself from other declared or potential candidates, his ability to secure party establishment support versus grassroots backing, and how well he performs in early polling and primary contests. The Republican primary process—including candidate filing deadlines, debate participation, and primary election results—will provide concrete data points that resolve much of this uncertainty.

Key factors:
- Candidate field composition: whether other major figures enter or exit the race before filing deadlines
- Early polling numbers among Florida Republicans and name recognition relative to competitors
- Fundraising totals and donor support indicators from quarterly FEC disclosures
- Endorsements from state party leadership, elected officials, and influential conservative figures
- Primary election results and vote share in early contests or the general primary itself

- Will Byron Donalds be the Republican nominee for Governor in Florida?: Byron Donalds — 94¢ Kalshi $10K (weight 29%)

## 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.
