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

Why this matters:
Markets estimate a 51% chance that eBay's Q2 2026 gross merchandise volume (GMV) will exceed $22.5 billion, based on aggregated contract prices showing declining confidence at higher thresholds. The 93% probability at the $21 billion level versus 51% at $22.5 billion suggests traders view baseline volume around $21–22 billion as highly likely, but meaningful growth beyond that as uncertain. Resolution depends on eBay's actual Q2 2026 GMV reported in their earnings release, typically published in late July or early August. Key factors include eBay's historical quarter-over-quarter GMV trends, macroeconomic conditions affecting e-commerce spending, competitive pressures from other platforms, and any material changes in seller participation or marketplace dynamics. The wide gap between the $21 billion floor and $23 billion ceiling reflects genuine uncertainty about whether eBay can sustain or exceed recent performance levels during the critical spring-summer selling season.

Key factors:
- eBay's Q1 2026 reported GMV and year-over-year growth rate will anchor expectations for Q2 performance
- Macroeconomic consumer spending data and e-commerce sector trends through May-June 2026 affect total marketplace transaction volumes
- Competitive market share dynamics with Amazon, Etsy, and other platforms influence seller activity and buyer participation on eBay's platform
- The specific GMV definition and calculation methodology used in eBay's official earnings report must match the contract specifications exactly
- Historical seasonality patterns show whether Q2 typically underperforms or outperforms annual averages for eBay's merchandise volume

## 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.
