18% — Will Taylor Swift be #1 on Spotify's Daily Top Songs Global chart for at least 3 chart days in June 2026 Kalshi 18% · 11 contracts · $4K volume · medium confidence Updated 2026-06-26 03:47:26 UTC Why this matters: This market asks whether Taylor Swift will claim the #1 spot on Spotify's global daily chart on at least 3 separate days during June 2026. The 29% probability reflects moderate skepticism about Swift achieving this threshold, likely driven by two competing forces: her consistent streaming strength versus the competitive field of other major artists releasing or promoting music in June. The outcome will primarily depend on whether Swift has a major release or campaign scheduled for the month, since new releases typically generate the streaming volume needed to capture chart leadership. The main catalyst for resolution will be Spotify's daily rankings throughout June, with particular attention to any Swift release dates announced before month-end. Key factors: - Whether Taylor Swift has a planned album release, re-recording, or major single drop scheduled for June 2026 - The comparative streaming momentum and promotional activity of competing artists (particularly Ariana Grande, who markets at 85¢ for 3+ days in June) - Historical patterns showing how many days per month top artists typically hold #1 on Spotify's global chart versus the 3-day threshold required - Real-time daily chart performance and streaming volume data throughout June 2026 as the month progresses - Whether June 2026 features coordinated release strategies from multiple major artists that could fragment chart leadership Contracts: - Will Taylor Swift be #1 on Spotify's Daily Top Songs Global chart for at least 3 chart days in June 2026?: At least 3 days — 3¢ Kalshi $2K (weight 53%) - Will Ariana Grande be #1 on Spotify's Daily Top Songs Global chart for at least 12 chart days in June 2026?: At least 12 days — 74¢ Kalshi $861 (weight 20%) - Will Ariana Grande be #1 on Spotify's Daily Top Songs Global chart for at least 15 chart days in June 2026?: At least 15 days — 36¢ Kalshi $683 (weight 16%) - Will Olivia Rodrigo be #1 on Spotify's Daily Top Songs Global chart for at least 12 chart days in June 2026?: At least 12 days — 38¢ Kalshi $154 (weight 4%) - Will Olivia Rodrigo be #1 on Spotify's Daily Top Songs Global chart for at least 18 chart days in June 2026?: At least 18 days — 3¢ Kalshi $139 (weight 3%) - Will Olivia Rodrigo be #1 on Spotify's Daily Top Songs Global chart for at least 15 chart days in July 2026?: At least 15 days — 3¢ Kalshi $74 (weight 2%) - Will Olivia Rodrigo be #1 on Spotify's Daily Top Songs Global chart for at least 12 chart days in July 2026?: At least 12 days — 5¢ Kalshi $38 (weight 1%) - Will Olivia Rodrigo be #1 on Spotify's Daily Top Songs Global chart for at least 9 chart days in July 2026?: At least 9 days — 6¢ Kalshi $37 (weight 1%) - ... and 3 more --- ## 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.
