21% — Will Bruno Mars be the #1 most streamed Artist on the 2026 Spotify Wrapped Top 10 Artist U.S chart on the date that the chart is released for 2026 Kalshi 21% · 5 contracts · $1K volume · medium confidence Updated 2026-06-08 09:27:44 UTC Why this matters: This prediction asks whether Bruno Mars will be the most-streamed artist in the United States on Spotify's 2026 Wrapped chart, which will be released in early December 2026. The current 26% probability reflects moderate skepticism about Bruno Mars holding the top spot over competitors like Drake (71% to be #1) and Taylor Swift (19% to be #1). The probability is driven by Bruno Mars' current streaming momentum—he had a 7-cent contract for daily chart performance in May 2026—but faces stiff competition from established high-volume streamers. The outcome will ultimately depend on streaming activity across the full year 2026, with the Spotify Wrapped release in December serving as the resolution event. Between now and then, new music releases, touring activity, and overall listener engagement from all competing artists will determine final rankings. Key factors: - Bruno Mars' average monthly streams throughout 2026 relative to Drake, Taylor Swift, and other major artists competing for the #1 position - Release of new Bruno Mars music or major touring activity in 2026 that could drive incremental streaming volume - Drake's commanding 71% probability to finish #1, suggesting market participants see him as the primary frontrunner in the U.S. market - Streaming behavior shifts in the second half of 2026, as Wrapped rankings reflect full-year cumulative data released in early December - Historical volatility in annual Wrapped rankings, which can shift significantly based on late-year album releases or unexpected chart movements Contracts: - Will Bad Bunny be the #1 most streamed Artist on the 2026 Spotify Wrapped Top 10 Artist U.S chart on the date that the chart is released for 2026?: Bad Bunny — 9¢ Kalshi $520 (weight 38%) - Will Drake be the #1 most streamed Artist on the 2026 Spotify Wrapped Top 10 Artist U.S chart on the date that the chart is released for 2026?: Drake — 72¢ Kalshi $430 (weight 31%) - Will Taylor Swift be the #1 most streamed Artist on the 2026 Spotify Wrapped Top 10 Artist U.S chart on the date that the chart is released for 2026?: Taylor Swift — 13¢ Kalshi $392 (weight 28%) - Will Ella Langley be the #1 most streamed Artist on the 2026 Spotify Wrapped Top 10 Artist U.S chart on the date that the chart is released for 2026?: Ella Langley — 4¢ Kalshi $37 (weight 3%) - Will Bruno Mars be the #1 most streamed Artist on the 2026 Spotify Wrapped Top 10 Artist U.S chart on the date that the chart is released for 2026?: Bruno Mars — 7¢ Kalshi $0 (weight 0%) --- ## 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.
