Swedish Open: Jan Choinski vs Nikoloz Basilashvili

Platform comparison

Market context

Jan Choinski faces Nikoloz Basilashvili in the opening round of the Swedish Open at ATP Bastad, with the match originally slated for 4:00 AM ET on 13 July 2026. The prediction market currently implies a 0% chance Choinski advances, a stark divergence from traditional sportsbook models that assign him a 55–56% win probability based on current moneyline odds of –172 [1][3].

Historical precedents in prediction markets show that such extreme crowd-implied probabilities often signal technical suspensions, player withdrawals, or settlement ambiguities rather than genuine sporting expectations. Comparable cases in tennis markets where crowd probability hit 0% typically resolved to the 50–50 clause after matches were cancelled or delayed beyond the seven-day window, not because the underdog was favoured to win on court [1].

Traders should monitor the ATP official schedule for any match postponement announcements, player injury updates, or withdrawal notices that could trigger the 50–50 settlement condition. The market’s USDC settlement and on-chain mechanics tie resolution to whether the match begins and completes within the seven-day window; any delay beyond 20 July 2026 at 08:00 UTC locks the outcome at parity. Recent ATP Bastad coverage confirms Choinski is the favourite, so the 0% probability likely reflects a non-play scenario rather than Basilashvili’s on-court superiority [2][3].

Methodology

This page reads Swedish Open: Jan Choinski vs Nikoloz Basilashvili 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.

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.

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.
