This event tracks the performance of Taylor Swift's song 'I Knew It, I Knew You' on the Billboard Hot 100 chart for the week of September 12, 2026. It evaluates where the song ranks among the most popular tracks in the United States during that specific week.
The event determines the ranking position of Taylor Swift's song 'I Knew It, I Knew You' on the Billboard Hot 100 chart for the week dated September 12, 2026. Each numbered market corresponds to a specific ranking position from #1 to #10. If the song achieves the exact ranking specified in any market, that market resolves positively (Yes). The secondary rules clarify that Billboard has not endorsed these markets, and any references to Billboard or the Hot 100 are purely descriptive, indicating no formal affiliation or endorsement by Billboard. The outcome is solely based on the official Billboard Hot 100 chart publication for the specified week.
While analyst forecasts offer expert opinions on song performance, prediction market odds aggregate crowd-sourced predictions that can react faster to new developments. Currently, traders are pricing in a specific probability for the song's chart position, which may diverge from or align with published analyst rankings. Comparing these two sources helps gauge whether the market is more bullish or bearish than professional evaluations on this market.
This market resolves around Sep 16, 2026, with the outcome confirmed once the official Billboard Hot 100 chart for that week is published and verifiable from credible public reporting. The final ranking will set the market's result based on where 'I Knew It, I Knew You' appears, if at all, on the chart dated Sep 12, 2026.
Key signals include weekly single sales data, streaming numbers on platforms like Spotify and Apple Music, radio airplay metrics, and any publicity events such as interviews or performances by Taylor Swift. Unexpected developments — like a viral moment or a change in promotion strategy — could also shift trader sentiment and move prices in this market as the September chart date approaches.
