Trade: BLAST Slam VII: Most Picked Hero
Resolution criteria on PolyGram: This market will resolve according to the hero with the most total picks 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 picked hero has not been declared within this timeframe, this market will resolve to "Other". If multiple heroes are tied for most picks, 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 will take place from 26 May to 7 June 2026, with professional Dota 2 teams competing across multiple matches to determine which hero receives the most total picks throughout the tournament. The current order book on Polymarket reflects a 49% implied probability, suggesting meaningful uncertainty amongst traders regarding which hero will lead in selection frequency across all games played during this window.
Historical precedent from major Dota 2 tournaments indicates that hero meta shifts significantly based on patch timing and competitive adaptation. The hero with most picks typically reflects the current patch's strongest utility or carry options, with heroes like Earthshaker, Rubick, and Invoker frequently dominating pick statistics at international events. However, tournament-specific factors—including team compositions, regional playstyles, and mid-event meta adjustments—create substantial variance. At The International 2023, no single hero exceeded 15% of total picks, demonstrating how distributed hero selection can become at elite levels.
Traders should monitor patch notes released before the tournament begins, as Valve's balance changes directly influence hero viability and competitive prioritisation. Team roster announcements and recent qualifier results will signal which heroes teams have been practising. The tournament schedule's exact match count remains a dependency; BLAST's official website and social media channels will confirm final details. Any significant roster changes or emergency patches between now and late May could substantially shift expectations around which heroes teams will prioritise, making real-time updates critical for position management.

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 Picked Hero" are the same as any other PolyGram 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.
- Sign in on polygram.ink with your email — no full KYC under $1,500 lifetime trading volume.
- Deposit USDC on Polygon (lowest fees, ~$0.01 per transaction) or Ethereum. Funds credit after 12 confirmations.
- 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.
- Size your position. If you stake 100 USDC at 50% YES, you'll receive shares that pay $200 if YES resolves true — a 100% gross return. If NO resolves, your shares are worth $0.
- Set risk controls (optional). Stop-loss, take-profit, and limit-order types all supported. Use the trade ticket's slippage box to cap your maximum entry price.
- Wait for resolution. When the event resolves on-chain via the UMA optimistic oracle, the winning side settles to 100¢ automatically and USDC hits your balance within seconds. Withdrawable to any wallet you control.
How active is this market?
$0 in lifetime turnover and $175 of resting liquidity puts this market in the below the median by volume for dota contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
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.
