Updated 2026-06-26 09:42:31 UTC

Why this matters:
This probability reflects the current market assessment that a specific song will top Spotify's global charts on April 21, 2026. At 21%, the outcome is considered unlikely but plausible. The pricing is driven by streaming volume trends and artist momentum as of mid-June 2026, with the leader maintaining a narrow edge over the runner-up at 13%. The resolution will be determined by Spotify's official global daily chart data on the target date. Factors that could shift the probability include unexpected viral moments, algorithm changes, or shifts in listener preferences over the remaining months. Since we are only 10 months from the resolution date, current streaming patterns and artist release schedules provide the most relevant signal for predicting chart positioning in April.

Key factors:
- Current streaming velocity and listener engagement metrics for the leading candidate versus competitors
- Planned major releases by other top artists between now and April 21, 2026
- Historical consistency of the current leader's chart performance over recent weeks
- Geographic distribution of streams—whether strength is concentrated or globally distributed
- Spotify algorithm updates or changes to chart calculation methodology that could affect ranking dynamics

Contracts:
- Top Global Song on Spotify on Jun 26, 2026?: hate that i made you love me — 20¢ 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.

## SF Signal

- SF Index, regime, and 30d Brier calibration are computed separately and surfaced at https://simplefunctions.dev/admin/calibration.
- No SimpleFunctions index / regime / calibration signal is bound to this topic yet — the headline above is market-derived only.
