Granby: Tyler Zink vs Alexis Galarneau

Platform comparison

Market context

Tyler Zink and Alexis Galarneau are set to face off in a Granby tennis match originally scheduled for 10:00 AM ET on 15 July 2026, with the outcome determining who advances in the tournament. In prediction markets, a YES share represents a bet that the specified outcome—here, Tyler Zink advancing—will occur, while a NO share bets it will not. The current crowd-implied probability of 0% YES suggests traders overwhelmingly expect Galarneau to win or the match to be cancelled, triggering a 50-50 settlement.

Historically, tennis prediction markets with near-zero probabilities often reflect either a severe injury, a withdrawal, or a mismatch in player form that has not yet been officially confirmed. Comparable cases from recent Grand Slam qualifiers show that such extreme odds can shift rapidly if a player’s fitness is clarified or if scheduling changes occur, particularly when matches are delayed beyond the standard window.

Traders should monitor official tournament announcements from Tennis Canada and the ATP for updates on player availability, as withdrawals or delays are the primary catalysts here. A recent report from the ATP website notes that Granby has faced multiple scheduling adjustments in 2026 due to weather, which could impact this match’s completion status and thus the market’s resolution [1]. Any delay beyond seven days without a winner will reset the market to 50-50, making timing and official confirmations critical.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Prediction Market UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
