Live prediction market odds for "Which artists will have a Billboard #1 song this year?". Mariah Carey leads at 93.3%. Next is Tate McRae at 66%. $476K has traded across 119 outcomes on Kalshi and Polymarket. The market is expected to resolve by Dec 31, 2026.
This market will resolve to “Yes” if any song by the listed artist is the number 1 song in any official weekly Billboard Hot 100 songs chart released for a data collection reference period entirely between January 1 and December 31, 2026. Otherwise, this market will resolve to “No”. Any song released with the listed artist as a primary artist will count, including songs released before 2026. If a song is released jointly by multiple artists credited equally as primary artists, it will count for all of them. Features, writing credits, production credits, or other forms of non-primary contributions to a song will not count. Artist attribution will be determined solely by the artists displayed by Billboard on the relevant chart. Billboard updates its Hot 100 songs chart each Tuesday (with adjusted release schedules on some holiday weeks), reflecting data collected in the previous week (Friday-Thursday). Each Billboard chart is then titled “Week of (date of the upcoming Saturday)”. The first Billboard Hot 100 song chart relevant to this market will be the chart titled “Week of January 17, 2026” for a data collection reference period of January 2-8, 2026. The final Billboard Hot 100 song chart relevant to this market will be the Chart titled “Week of January 9, 2027” for a data collection reference period of December 25-31, 2026. Updates or revisions made within this market’s timeframe to the #1-ranked song on previously published Billboard Hot 100 charts will be considered; however, such updates will not disqualify a previously published Billboard Hot 100 #1 song from counting. If a Billboard Hot 100 #1 song is revised after initial publication, both the originally published #1 song and the revised #1 song will count for this market. Updates or revisions made after the release of the final Billboard Hot 100 song chart relevant to this market will not be considered. The resolution source for this market will be the weekly Billboard Hot 100 songs charts published each week at https://www.billboard.com/charts/hot-100/ and through other official Billboard channels.
It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.
A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.
Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.
Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.
