Trade: BLAST Slam VII: Most Banned Hero
Resolution criteria on PolyGram: This market will resolve according to the hero with the most total bans across all matches at BLAST Slam VII, currently scheduled for May 26th - June 7th, 2026. If this tournament is cancelled, postponed after June 10, 2026, 11:59 PM ET, or a most banned hero has not been declared within this timeframe, this market will resolve to "Other". If multiple heroes are tied for most bans, this market will resolve in favor of the hero whose listed name comes first alphabetically. The resolution source for this market will be official information from the tournament organizer, BLAST (https://blast.tv/dota/tournaments/blast-slam-vii).

Market context
BLAST Slam VII is a Counter-Strike 2 tournament scheduled for 26 May to 7 June 2026, where the market tracks which hero character receives the most total bans across all matches. The current order book on Polymarket implies a 50% probability for a clear most-banned hero being declared, reflecting genuine uncertainty about whether the tournament proceeds as scheduled and whether a decisive ban leader emerges from the competition.
Historical precedent from esports tournaments suggests that ban distributions typically concentrate around meta-defining heroes rather than spreading evenly. In previous BLAST events and major Counter-Strike competitions, dominant heroes often accumulate 15–25% of total bans when the meta is settled, though this varies considerably depending on patch timing and team preparation. The 50% implied probability reflects material execution risk: the tournament could be postponed beyond the 10 June resolution deadline, cancelled entirely, or produce a tie requiring alphabetical resolution. These settlement conditions create meaningful friction compared to standard tournament markets.
Traders should monitor BLAST's official announcements regarding venue confirmation and scheduling, particularly given the compressed May–June window. The Counter-Strike 2 patch cycle leading into the event will shape hero viability; any significant balance changes in the months prior could shift ban patterns substantially. Team roster announcements and scrim results, typically shared on esports news outlets like HLTV and Liquipedia, often signal which heroes teams prioritise banning. The alphabetical tie-break rule also matters: if two heroes reach identical ban counts, the resolution favours whichever comes first alphabetically, creating a secondary layer of outcome determination.

How this market resolves
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.
How to trade this market step by step
The mechanics for trading "BLAST Slam VII: Most Banned Hero" are the same as any other PolyGram sporting event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.

- Pick a side. Buy YES if you believe the event will happen; buy NO if you think it won't. The current YES price reflects the market's collective probability.

How active is this market?
$1K in lifetime turnover and $30K of resting liquidity puts this market in the below the median by volume for sports contracts on PolyGram. Order-book depth is strong — order books support five-figure trades with single-cent slippage.
Last 24 hours alone saw $1K in turnover, well above the lifetime daily-average for this market — a clear sign of news catalysing trader activity right now.
The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
Key terms
- YES / NO share
- A binary outcome token that pays $1.00 if the underlying claim resolves true (YES) or false (NO), and $0 otherwise. The market price between 0¢ and 100¢ is the implied probability.
- CLOB
- Central limit order book. The matching engine that pairs YES buyers with NO buyers (effectively the same trade). Polymarket's CLOB on Polygon executes trades on-chain via the conditional-tokens framework.
- Liquidity
- USDC capital sitting in resting limit orders inside the order book. Deeper liquidity means smaller slippage on large trades and a tighter bid-ask spread.
- UMA optimistic oracle
- The on-chain dispute system that settles each Polymarket market. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution.
- Slippage
- The difference between the displayed mid-price and your fill price. Affects market orders most; limit orders avoid slippage but may take time to fill.
- Conditional token
- ERC-1155 outcome share issued by Gnosis Conditional Tokens on Polygon. The token type that resolves to $1.00 or $0.00 at settlement.

Risk and regulatory note
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.
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.
