Resolution criteria on PolyGram: Billboard updates its Hot 100 songs chart each Tuesday (with adjusted release schedules on some holiday weeks), reflecting data from the previous week (Friday-Thursday). Each Billboard chart is then titled “Week of (date of the upcoming Saturday)”. This market will resolve according to the number 1 song on the Billboard Hot 100 chart titled “Week of May 30, 2026”. This market will resolve as soon as the relevant chart is published. If the Billboard Hot 100 chart for the specified week is not published within 14 calendar days of the expected release date, this market will resolve to “Other”.
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 2 days to resolution — final-48h markets historically see the largest volume spikes, backed by $16K 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.

Award shows, reality TV and streaming-hit markets resolve from the official broadcaster announcement or industry body (the Academy for the Oscars, the EBU for Eurovision, Nielsen for US ratings). Because these events have moderate liquidity but high public interest, odds can move sharply as finalists are announced or critics' picks go public. PolyGram routes your order into the same Polymarket order book with a single-tap trading UX.
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.

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.

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 "Billboard Hot 100 #1 Song Week of May 30", 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.
