Resolution criteria on PolyGram: Spotify curates a playlist of the most streamed songs globally and updates it on Fridays to reflect streaming data for the previous week, beginning on the preceding Friday and ending on Thursday. This market will resolve according to the most-streamed song in the U.S. on Spotify for the week labeled May 29. If Spotify does not release its top song for the week labeled May 29 by May 30, 2026, 11:59 PM ET, this market will default to "Other". The resolution source for this market will be official information from Spotify. The weekly top songs - USA chart can be found on open.spotify.com under the "Charts" heading.
Entertainment and pop-culture markets price events that traditional bookmakers won't touch — award winners, viral moments, cultural milestones. Current odds favour the NO side at 1%, making this a high-confidence market with 1 day to resolution — final-48h markets historically see the largest volume spikes, backed by $10K of resting liquidity.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.

Spotify publishes its weekly top-streamed song in the United States every Friday, with the May 29, 2026 chart reflecting streaming activity from Friday, May 22 through Thursday, May 28. The current orderbook on Polymarket prices the outcome at 1% implied probability, suggesting traders assess an extremely low likelihood that any single song will dominate that specific week's streaming data sufficiently to rank as the platform's number-one track.
Historical context shows that Spotify's weekly top songs typically concentrate streaming volume amongst established artists with sustained cultural momentum. Recent chart leaders have included tracks from artists with existing fanbase loyalty rather than surprise debuts, though viral moments and new releases from major acts can shift rankings substantially week-to-week. The 1% pricing reflects the inherent difficulty in predicting which track will accumulate the most streams across millions of US listeners during a seven-day window, particularly when multiple competing releases may fragment listening patterns.
Traders monitoring this market should track major music releases scheduled for the week of May 19–28, 2026, and any surprise drops from chart-dominant artists. Announcements from major labels regarding release strategies, festival performances, or streaming campaigns could influence weekly totals. Polymarket's order book will adjust as the settlement date approaches and more information about competing releases becomes public; currently, the extreme probability discount suggests the market is pricing in genuine uncertainty about which track will lead, with the "Other" outcome heavily favoured by the orderbook structure.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
For this market, the resolution date is 29 May 2026. A UMA proposer can submit the outcome from that moment; the two-hour dispute window closes at , and assuming no counter-claim is staked, winning USDC clears to trader balances by approximately .
If a dispute is filed inside the two-hour window, the outcome escalates to UMA token-holder voting, which extends settlement by roughly 48 hours. This particular market has no public resolution feed listed; disputes here are more likely if the underlying outcome is subject to interpretation, in which case the UMA token-vote arbitrates the wording of the original market question.
Pop-culture and entertainment markets settle from press releases or official announcements; if the underlying event reschedules, PolyGram extends the resolution date accordingly and re-opens trading until the new date.

Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose. For "#1 song on US Spotify this week? (May 29)", the considerations above apply directly — Entertainment markets often have thinner books than sports or crypto contracts — a single $1k order can move the line several cents, so position-sizing discipline matters more here than in deeper markets.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
