Billboard's Song of the Summer is the most-watched chart of the year. Polymarket (opens in a new tab) and Kalshi (opens in a new tab) run Song of the Summer contracts that resolve in early September based on Billboard's official summer ranking: which uses Memorial Day through Labor Day Hot 100 chart performance. Here's the 2026 race and how to trade it from California.

How does Billboard define Song of the Summer?

Billboard defines the Song of the Summer based on cumulative performance on the Hot 100 chart between Memorial Day and Labor Day, factoring in streaming, radio airplay, and sales.

Billboard's official Song of the Summer chart ranks songs by their cumulative Hot 100 performance from the Memorial Day weekend chart through the Labor Day chart. The chart blends streaming, radio, and sales weighted by Billboard's standard Hot 100 methodology. The winner is announced in early September.

Who's in the 2026 race?

Potential 2026 Song of the Summer candidates include emerging viral artists and established musicians with scheduled spring releases, though the final field remains unpredictable.

As of April 2026, the field is still forming. The Song of the Summer race is unusual because it's almost impossible to predict the winner before late spring: viral TikTok moments, surprise releases, and radio breakthroughs reshape the chart in real time. Early candidates based on current chart performance and label release schedules:

Sabrina Carpenter follow-up. Coming off "Espresso" winning Song of the Summer 2024, any new Carpenter single drops with built-in market expectation. Her Short n' Sweet follow-up is rumored for summer 2026.

Billie Eilish. Following Hit Me Hard and Soft's success and her tour, a single release in late spring 2026 would land in the contention window.

Olivia Rodrigo. Long rumored to have new material in 2026. Her past single performance suggests a Song of the Summer-ready hit.

Bad Bunny. "DeBÍ TiRAR MáS FOToS" yielded multiple Hot 100 entries; summer-spec singles likely.

Drake / Future / Travis Scott. Rap chart releases in May-June often dominate the summer chart.

Country crossover. Morgan Wallen, Zach Bryan, and Shaboozey-style country crossovers have dominated recent Song of the Summer races. Shaboozey's "A Bar Song (Tipsy)" was Song of the Summer 2024-adjacent and broke records.

Song of the Summer is won in May and June. By August, the trade is over.

What's the historical pattern?

Winners typically consist of dance-pop or pop-country uptempo singles released between late April and early June that maintain high performance across both streaming and radio platforms.

Recent Song of the Summer winners: "Espresso" (Sabrina Carpenter, 2024), "Calm Down" / "Last Night" / "Flowers" cycle (2023), "About Damn Time" (Lizzo, 2022), "Stay" (Justin Bieber & Kid Laroi, 2021). The pattern: dance-pop or pop-country uptempo singles released between late April and early June, with strong streaming AND radio play.

Songs that arrive after July 4 almost never win Song of the Summer because they don't have enough chart weeks to accumulate the cumulative ranking required.

What's the trade?

The trade involves identifying songs released in early summer that benefit from the combination of a major-label radio push and viral momentum on social media platforms.

The asymmetric play is identifying a song that combines: (1) major-label radio push, (2) viral TikTok or social moment, (3) release date in May or early June. Songs that hit all three by mid-June typically lock the race by July. Markets that price a clear leader at 30-40% in mid-July are usually correctly priced.

The trap: betting on a star artist's late-summer release. A Taylor Swift August single can dominate the Hot 100 but often doesn't have enough cumulative weeks to win Song of the Summer.

How should I time my trades?

Optimal trading timing involves entering positions on artists with June singles in April or May before using early streaming data from late May to refine selections by early July.

Timeframe	Action/Guidance
April-May 2026.	Markets open with broad fields. Early positions on artists with confirmed June singles offer the best risk/reward.
Memorial Day weekend.	The chart window opens. Early streaming numbers from the first week clarify the field.
Independence Day weekend.	By July 4, the leading candidates are usually visible. Markets get most efficient.
Late August.	Final two chart weeks. Resolution markets close.

Where can I trade this from California?

California residents can trade these markets legally on the CFTC (opens in a new tab)-regulated platforms Polymarket and Kalshi.

Polymarket and Kalshi both run Song of the Summer multi-outcome markets. Polymarket has historically carried deeper liquidity on multi-artist contracts; Kalshi is cleaner for individual binary contracts on specific songs. Both are CFTC-regulated and available to eligible California residents (dispute pending). For more music coverage, see our Grammys 2027 guide and Coachella 2027 guide.

Frequently asked questions

What is the Song of the Summer prediction market?

Song of the Summer is an industry-recognized title for the song that dominates the Billboard Hot 100 between Memorial Day weekend and Labor Day. Kalshi has historically listed event contracts on which specific song will hit #1 during that window and which will spend the most cumulative weeks at #1. The contract typically opens in May and resolves in early September.

Who is currently #1 on the Hot 100 in 2026?

As of late April 2026, per Billboard's official Top 10, recent #1s include Bruno Mars' 'I Just Might,' with 'Folded' by Kehlani, 'Stateside,' 'So Easy,' HUNTR/X, and Ella Langley's 'Be Her' all charting in the top 10. The chart has had unusual turnover so far in 2026 compared to the long-stay #1s of 2024-2025.

Can Californians trade Hot 100 markets?

Yes. Kalshi has CFTC-regulated music chart contracts including specific-song-#1 markets and weeks-at-#1 thresholds. They're legal in California under federal commodities law. Polymarket has lighter coverage but carries select chart contracts.

Who are the early Song of the Summer 2026 favorites?

Sabrina Carpenter (following her 'Please Please Please' #1 run from 2024), Bad Bunny on his summer release cycle, Taylor Swift carrying singles from 'The Life of a Showgirl,' and a likely Drake or Kendrick Lamar project. The list firms up significantly through May as release calendars solidify.

How does the Hot 100 #1 contract work?

Kalshi typically lists per-song contracts (e.g. 'Will [Song X] hit #1 on the Billboard Hot 100 by [date]') with binary YES/NO resolution. Some markets list weeks-at-#1 thresholds (e.g. 'Will any song spend 6+ weeks at #1 in 2026'). Resolution is via official Billboard chart data.

When is the music market most active?

Three windows: major album release weeks (Friday drops produce immediate chart movement), the chart-cycle week of Memorial Day (Song of the Summer race opens), and the final week of August (Song of the Summer resolution).

What's a smart strategy for music chart trading?

Music charts are momentum markets. Songs that gain in week 1-2 typically continue to climb. Most edge comes from tracking streaming data (Spotify weekly playlists, TikTok virality) one cycle ahead of Billboard's published numbers. The professional traders watch Luminate data; retail traders mostly react to chart Tuesday.

Is this different from trading the Grammys?

Yes. Hot 100 contracts resolve to commercial chart performance (objective). Grammy contracts resolve to Recording Academy voting (subjective). Both are CFTC-regulated event contracts; chart markets carry tighter spreads because the underlying data is unambiguous.

What are the minimum trade sizes for Billboard chart contracts?

Polymarket and Kalshi allow trades for as little as one dollar. Because these contracts trade between zero and one hundred cents, you can enter a position with very low capital. There are no fixed minimums like those found in traditional brokerage accounts, making music markets accessible for casual participants looking to hedge against or profit from chart movements.

How are earnings from music prediction markets taxed in California?

Profits are subject to federal and California state income tax. Kalshi provides a profit-and-loss statement for your trades at the end of the year. Polymarket US hasn't clearly published which tax forms its app issues, so keep your own records and report your gains and losses on your federal and California returns.
