Market context
Nemiga Gaming’s Dota 2 meeting with Ilbirs eSports in the EPL Masters Play-In Group B is the underlying event here, with the market still effectively pricing in no completed result. A 0% YES reading usually means traders see either a very low probability of a listed Nemiga win or a strong chance the contract will end up settling to the fallback 50-50 path if the match is not completed or is materially altered before the deadline.
The closest comparable read is that third-party match pages were still treating Nemiga as the side to back, with Stavka TV publishing an AI pick for a Nemiga win at odds of 1.85 on 24 July 2026.[1] That sort of pre-match leaning matters mainly as a reference point, not as proof of outcome: in esports, late lineup changes, walkovers, no-shows, or schedule slippage can matter more than nominal team strength, especially in play-in group stages where organisers may compress fixtures or reschedule around broadcast and server availability. If the series starts on time and completes, the market should resolve to the match winner; if it is delayed beyond seven days from the scheduled date without a winner, or is not played at all, the fallback is 50-50.
For traders watching the on-chain angle, the key issue is whether the contract can still resolve cleanly before the settlement window closes, because USDC-denominated markets usually reprice fastest when there is confirmation of roster lock, lobby creation, or an official fixture update. Absent a live score source in the contract itself, the best catalysts are tournament announcements, a changed start time, or a published match page confirming whether the series has actually begun; if broader crypto conditions are relevant, BTC and ETH spot and funding usually matter only indirectly here, by affecting risk appetite rather than the match-specific outcome.

Methodology
Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — sit alongside as off-chain reference points so you can see how the contract translates across regulatory and settlement regimes.
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.
- Why USDC and not ETH or USDT?
- USDC is the Polygon standard — audited reserves (Circle, monthly attestation), deepest order book, low gas costs. ETH volatility would distort probability quotes; USDT has thinner Polygon liquidity than USDC.
- Can I use Bitcoin directly?
- No, Polymarket operates exclusively in USDC on Polygon. You can bridge BTC to USDC via an exchange or bridge service and deposit on Polygon — typically 10-30 minutes processing time.
- 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.
- 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.
