Tracks the leading outcome in a winner-take-all prediction market set with 4 outcomes.

Why this matters:
Markets are pricing a 42% probability that Senator Jon Ossoff announces a presidential campaign before October 1, 2027. Ossoff has not publicly expressed interest in a 2028 presidential run and faces significant structural headwinds: his focus on Senate duties, limited national profile outside Georgia, and the difficulty of mounting a viable campaign against established contenders. The probability could rise if he signals ambitions through rhetoric, endorsements, or organizational steps; it could fall if he explicitly distances himself from a White House bid or commits to Senate races. The most important catalyst will be whether any candidate announcements occur between now and the deadline, as early movers typically shape the viability calculus for remaining potential candidates.

Key factors:
- Ossoff has made no public statements indicating presidential ambitions as of mid-2026, and has focused on Senate committee work and Georgia-specific priorities
- The next concrete signal would be organizational moves (hiring senior staff, travel patterns, fundraising positioning) that precede formal announcements
- Timebound resolution: announcements typically cluster after midterm elections when candidates test viability; most 2028 contenders will likely declare between late 2026 and spring 2027
- Structural constraint: Ossoff represents a single state and lacks the national committee network or executive experience typically preceding top-tier presidential bids
- Calendar pressure: the 15-month window to October 2027 is relatively short—most viable candidates announce 18-24 months before the general election

## 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.
