Why this matters:
This market estimates a 26% probability that Julia Letlow will win Louisiana's 2026 Republican Senate primary by a margin between 6% and 9%. The relatively low probability reflects uncertainty about whether her victory, if it occurs, will fall within this narrow band rather than by a larger or smaller margin. The outcome depends on the Republican primary field composition—whether other strong candidates enter the race and how consolidated the anti-Letlow vote becomes. Primary voting on Election Day will definitively resolve whether she wins and by what exact margin. Key uncertainties include candidate entry decisions, turnout patterns, and how vote distribution across competing candidates affects her final margin.

Key factors:
- Field size and candidate quality: Whether credible Republican challengers besides the current runner-up enter the race materially affects vote concentration and margin outcomes
- Letlow's baseline support: Polling data on her current standing versus potential rivals indicates whether she has a natural ceiling or floor in the 6-9% margin range
- Campaign dynamics: Endorsements, spending, and candidate positioning in the months before voting could shift vote distribution enough to move Letlow's margin outside this specific band
- Primary turnout: Total voter participation and demographic composition of those voting influences whether Letlow's core support translates to a 6-9% or different margin
- Runoff possibility: Louisiana's runoff rules mean results depend on first-round performance; if no candidate reaches the threshold, dynamics change entirely

Contracts:
- Will the margin of victory for Julia Letlow in the first round of the 2026 Louisiana Republican Senate primary be between 3% and 6%?: Julia Letlow, 3-6% — 3¢ Kalshi $0 (weight 100%)

## 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.
