Market context
RMD Gaming’s match with Vivo Keyd Stars Academy in Circuito Desafiante is already an on-chain settlement event: the contract pays out in USDC according to the official result, while a no-contest, cancellation, or excessive delay pushes the market to 50-50 rather than a win for either side. The current 0% YES print sits alongside a fragile live-information set: one match database shows a July 22 Bo1 finished with Vivo Keyd Stars Academy winning 1-0, while another list still displays the pairing in the current schedule, which is exactly the sort of ambiguity that can keep a market pinned near an extreme until the organiser’s official bracket and results are fully reflected.[2][3]
Comparable cases suggest traders should treat this as a logistics and confirmation market as much as a strength-vs-strength one. Earlier head-to-head records in the same competition have split both ways, with RMD Gaming winning one Bo1 in April and Vivo Keyd Stars Academy winning another later meeting, so historical form does not support a clean one-sided read.[1][2] A 0% crowd-implied probability usually reflects either a belief that the market has effectively already been decided, or that the outcome has been overwhelmingly priced in by recent result feeds rather than by team balance; in this setting, the more relevant question is whether the contract’s settlement source recognises the match as completed and which side is recorded as the winner.[1][2]
The catalysts to watch are official schedule posts, result updates from the competition operator, and any rescheduling beyond the seven-day window that would force the 50-50 fallback. If the July 22 fixture has indeed been finalised, the market should move on the published result rather than team-level macro; if it has not, confirmation risk remains the key driver. Broader crypto conditions matter mainly through the settlement rail: with USDC still the payout asset, there is little direct BTC or ETH linkage unless exchange-side volatility affects risk appetite or liquidity in the market book.

This page reads LoL: RMD Gaming vs Vivo Keyd Stars Academy (BO1) - Circuito Desafiante Regular Season on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement.

Every CTA routes to BTC Prediction, which mirrors the Polymarket order book directly.
Resolution & payout
Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.
Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.
FAQ
- What are crypto prediction markets?
- Crypto prediction markets are on-chain smart contracts where you buy YES or NO shares on a future crypto event (e.g. "BTC above $100k by year-end"). The market price between 0¢ and 100¢ is the implied probability.
- What does a transaction cost on Polygon?
- Polygon gas is typically under $0.01 per transaction. A full trade cycle (Approve + Order + Fill) totals around $0.03 — compared to $5-50 on Ethereum mainnet.
- How volatile are crypto prediction markets?
- Crypto markets react to spot prices — a 5% BTC move typically shifts a "BTC above X by date" market 10-20%. Polymarket crypto market liquidity is usually six-figure USD, sufficient for active trading.
- Which crypto markets exist on Polymarket?
- Currently active markets include BTC/ETH/SOL price targets, halving dates, ETF approvals, hard-fork outcomes and Layer-2 TVL thresholds. The list updates weekly; biggest volume sits on BTC and ETH price forecasts.
- Are crypto prediction markets taxable in the US?
- In the US, prediction market gains are typically treated as ordinary income or short-term capital gains depending on holding period. Consult a tax professional for your specific situation — we cannot provide tax advice.
