Tracks the leading outcome in a winner-take-all prediction market set with 5 outcomes.

Why this matters:
Markets are pricing a 95% chance that James McDonald will be confirmed as U.S. Attorney for the Southern District of New York before the end of 2026. The high probability reflects market confidence in confirmation occurring within the remaining timeframe, though shorter-term contracts show more uncertainty—traders see roughly 47% odds of confirmation by mid-July and 82% by October 1st. The confirmation timeline depends on Senate Judiciary Committee scheduling, floor debate duration, and whether any substantive opposition emerges during the vetting process. The main catalyst is the Senate's confirmation vote itself, which will occur once the committee advances the nomination and leadership schedules floor time. Current trading patterns suggest most traders expect confirmation in August-September 2026.

Key factors:
- Senate Judiciary Committee has not yet voted on the nomination; committee scheduling determines when floor consideration begins
- The probability gradient across dates (47% by Jul 18, 95% by Jan 1) indicates market expects confirmation in late summer or early fall 2026
- No publicly reported holds, objections, or controversy has emerged around the nominee as of mid-June 2026
- U.S. Attorney confirmations typically pass with bipartisan support unless significant ethical or legal issues surface during vetting
- The 14-week window between now and January 1 provides substantial time for a multi-stage confirmation process

## 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.
