Market context
Petr Bar Biryukov and Alastair Gray were due to meet in the Bengaluru Challenger on hard courts, a matchup that has already produced a completed three-setter in this event. ATP stats from Bengaluru show Gray winning the earlier meeting 6-7(5) 6-4 7-6(3), which is the clearest recent comparable for how tight the pair can be on this surface. That matters because the market is currently priced at 100% YES, leaving no room for a cancellation, retirement or walkover outcome despite those being built into the settlement rules. Against that backdrop, any live trading read should be anchored more to whether the match is actually staged than to who is favoured to win.
The main comparison point is the gap between the contract price and the available external signals. Flashscore listed Gray as the winner in the semi-final context, while ATP and Livescore pages point to the earlier Bengaluru meeting being played and decided on court; Tipstop’s preview leans Gray on recent win rate and notes both players often go deep into three sets outside Grand Slams. That is a reasonable analyst consensus for a close contest, but it does not support a 100% implied probability on either side once non-runner risk is included. Traders should watch the official Bengaluru order of play, ATP Challenger updates and any late withdrawals or schedule reshuffles before the 29 May settlement deadline, because a no-contest outcome would force a 50-50 resolution even if the market has been treated as a certainty.
Methodology
This page reviews Bengaluru 3: Petr Bar Biryukov vs Alastair Gray across five venues. We show live odds for Polymarket-based markets (sourced from the Polygon order book); for other venues we list platform attributes, since the comparable contracts are not exposed via a public API on every venue. Every CTA points at PolyGram — the application we operate, where you trade directly against the Polymarket order book at 0% fees.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
FAQ

- Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.
