Market context
Elsa Jacquemot’s match with Carol Young Suh Lee in Warsaw is the live event behind this market, but the current **0% YES** price is best read as a contract-state issue rather than a pure tennis view. Public match listings place the contest on the Warsaw clay event card, with Jacquemot and Lee both shown in recent round listings and rankings around WTA 98 and WTA 162 respectively, which is broadly consistent with a lopsided but playable lower-tier WTA meeting.[1][3][5]
For comparison, tennis prediction markets often drop to near-zero when the market is stale, the match has already started elsewhere in the data feed, or the event has been disrupted and the settlement logic no longer points to a normal completion. Here, the key nuance is that the contract settles to the named winner only if the player advances, while cancellation, tie, or a delay beyond seven days pushes it to 50-50. That means traders should separate *match quality* from *oracle completion risk*: a 0% quote can coexist with a live sporting event if the underlying feed has not reconciled the result path cleanly.[1][4][9]
The main catalysts are operational rather than macro. Watch for official Warsaw scheduling updates, live score feed confirmation, and whether the match is marked completed, retired, or moved, because those are the events that determine whether the market resolves to a named winner or snaps to 50-50 under the seven-day rule.[1][4][9] On-chain, the relevant mechanics are straightforward: the market settles in USDC, so the practical question is whether the result can be finalised before the settlement window closes on 10 August, with no obvious need to price BTC or ETH unless broader crypto volatility is affecting platform liquidity or funding conditions.
Methodology
This page reads Warsaw: Elsa Jacquemot vs Carol Young Suh Lee on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement. Kalshi (USD, off-chain), Betfair (GBP/EUR, off-chain) and Manifold (play-money) are listed alongside for venue context. 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.
- 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.
- 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.
- 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.
