Why this matters:
This represents the estimated likelihood that Brittany Mahomes, wife of Kansas City Chiefs quarterback Patrick Mahomes, will attend a wedding between Taylor Swift and Travis Kelce. The 65% probability reflects moderate confidence in her attendance, likely driven by the close relationship between the Mahomes and Kelce families within the NFL, as well as Swift and Kelce's public connection. The primary factors influencing this estimate are social ties within the sports-celebrity circle and typical wedding guest patterns for high-profile athletes' families. The main catalyst for resolving this uncertainty would be either an official wedding announcement with a guest list, media confirmation of attendance plans, or the wedding date itself occurring. Until then, probabilities remain anchored to observable relationship indicators and historical precedent for similar high-profile events.

Key factors:
- Patrick Mahomes' probability of attendance markets at 80-91% across platforms, suggesting the market expects him to attend and potentially bring family members
- Brittany Mahomes maintains active social media presence and regularly attends NFL events and celebrity functions alongside her husband
- Historical precedent: high-profile athlete spouses typically attend weddings of teammates' family members, particularly when social circles overlap
- No official wedding announcement, date, or guest list has been publicly confirmed as of May 2026
- Travis Kelce and Taylor Swift's relationship status and public commitment level would directly influence family inclusion in wedding planning

## 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.
