What Is Clash Sport? 60-Second Up/Down Calls on Live Sports, Explained

The core loop: pick, call, get paid on the move

Every live Polymarket sport and esport is playable — football, basketball, tennis, cricket, American football, hockey, UFC, CS2, League of Legends, Valorant, Dota 2 and more. Each game has a live win probability for one side, taken from the real order book, that moves with every possession, point and round.

You pick a game, choose a stake from your USDG balance, and tap UP or DOWN. Your round starts on the next 5-second mark about 30 seconds later and runs exactly 60 seconds. If the probability finishes higher than it started, UP wins; lower, DOWN wins. A perfectly flat finish counts as a loss.

• Payout scales with the size of the move: stake × multiplier, from 1.01x to 33x, less a 2% fee on the profit
• Multiplier = 1 + 4 × 2.13 × move ÷ σ, where σ is the market’s recent volatility
• Flat or wrong way: the stake goes to the house LP and you mint CLASH
• Esports games show the live stream right next to the chart

Who is on the other side: a house that started at $0

Every call is taken by a shared house LP — so there is always a counterparty, instantly, at any stake the house can cover. The LP started at $0, accepts no deposits and grows only from player losses.

Winners always get their stake back immediately. If the LP doesn’t have the cash for a win’s profit, the unpaid part becomes a first-in-first-out ticket, and every later loss repays the queue before anything else. You claim a ticket from your account once the queue reaches it.

Every loss mints CLASH

CLASH is fair-launched: supply started at zero, with no team or investor allocation. It is minted only to losing bets — 100 CLASH per $1 lost — and the rate decays once the house LP’s gross House Funds first pass $2M.

Fees fund the ecosystem: 2% of every winning profit and 2% of every loss (taken from the house’s share, never added to the loss), split 50% to CLASH stakers in USDG and 50% to the treasury. CLASH is non-transferable at launch; you can stake, unstake and claim.

Fully on-chain, built on Robinhood Chain

Deposits, bets, boundary prices, payouts, tickets, emission and staking are contracts on Robinhood Chain that anyone can read. Each quote is an EIP-712 signature the game contract verifies, and withdrawals, settlement, refunds and ticket claims can never be paused.
