Granby: Murphy Cassone vs Tristan Schoolkate

Platform comparison

Market context

The underlying event is a scheduled ATP Challenger tennis match in Granby between Murphy Cassone and Tristan Schoolkate, originally set for 10:00 AM ET on 13 July 2026. With the crowd-implied probability at 100% YES for Cassone advancing, the market treats his victory as a certainty, implying no material risk of cancellation, injury, or delay beyond the seven-day settlement window.

Historically, prediction markets assigning 100% probability to a single outcome in tennis rarely encounter settlement to the 50-50 tie clause unless a match is abandoned before a point is played. Comparable cases from the 2024–2025 ATP Challenger circuit show that when odds reach this extreme, the contract typically resolves cleanly within hours of the final point, with USDC settlement occurring on-chain without macro BTC or ETH volatility interference. Funding rates on related tennis derivatives have remained flat in such scenarios, indicating negligible whale flow or speculative hedging.

Traders should monitor the official ATP schedule for any post-match delays or official cancellations, as these are the only catalysts that could trigger the 50-50 resolution clause. The match’s completion is also dependent on weather conditions in Granby, Quebec, which can occasionally disrupt outdoor play. Recent reports from Tennis Canada confirm no weather alerts for the Granby venue as of 14 July 2026, reducing the likelihood of a delay beyond the settlement threshold [1].

Methodology

This page reads Granby: Murphy Cassone vs Tristan Schoolkate 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 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.
