Bunschoten: Gilles Arnaud Bailly vs Filippo Romano

Platform comparison

Market context

The underlying event is a scheduled ATP-level tennis match in Bunschoten between Belgian Gilles-Arnaud Bailly and Italian Filippo Romano, set for 4:00 AM ET on 13 July 2026. With the crowd-implied probability for Bailly advancing at 0% YES, the market reflects near-total consensus that Romano will win or the match will not produce a Bailly victory under current conditions.

Historically, such extreme probabilities in low-tier tennis markets often precede either a walkover, injury withdrawal, or a mismatch where one player is significantly outclassed or unavailable. In comparable cases from 2024–2025 on crypto prediction platforms, 0% YES markets for lower-ranked players resolved to 50-50 when matches were canceled or delayed beyond the settlement window, rather than confirming a loss. Bailly’s career-high ATP ranking of 201 and 56% overall win rate suggest he is competitive at this level, making the 0% pricing unusual unless external factors like fitness or scheduling conflicts are known to the crowd but not publicly disclosed.

Traders should monitor the official ATP tournament schedule and player entry confirmations for Bunschoten, as well as any late injury reports or withdrawal notices from the ITF or ATP Tour. A recent ITF update on player availability for European summer events could clarify whether Bailly is still entered [5]. On-chain, watch for USDC settlement flows and whale activity around the contract; if BTC or ETH funding rates shift sharply, it may signal macro-driven capital rotating into prediction markets, potentially altering liquidity and pricing before the 2026-07-20 settlement deadline.

Methodology

This page reads Bunschoten: Gilles Arnaud Bailly vs Filippo Romano 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

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 does UMA secure the resolution?

The UMA Optimistic Oracle uses a bond system: a proposer posts a bond, a two-hour challenge window opens. On dispute the losing side forfeits the bond — financial incentive for honest resolution.

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.
