Bengaluru 3: Petr Bar Biryukov vs Alastair Gray

Platform comparison

Active sub-markets

Market context

Petr Bar Biryukov and Alastair Gray were scheduled to meet in the Bengaluru Challenger, and the contract only resolves to a side if the match has a winner or an advancement outcome is recorded. ATP score archives show Gray won their earlier Bengaluru meeting 6-7(5) 6-4 7-6(3), which is useful context because it points to a genuinely close matchup rather than a routine favourite-vs-outsider pairing. That is consistent with the broader market signal: a 100% YES price implies the platform is already treating the event as effectively certain to resolve on a named player rather than fall back to the 50-50 no-play logic.

For traders, the main catalysts are simple and binary: official completion of the match, any tournament scheduling change, or a withdrawal before play starts. Bengaluru Challenger fixtures can shift quickly, and the settlement window matters because a match not played at all, or delayed beyond seven days without a winner, settles 50-50 under the contract terms. The on-chain angle is that final resolution should flow into USDC settlement once the oracle outcome is posted, so the key question is less about in-match score flow and more about whether the tournament produces an official result inside the stated window. BTC and ETH price action is not a direct driver here, though wider risk sentiment can affect liquidity and spreads around fast-moving sports markets.

Methodology

Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — are listed with their platform attributes, because they operate off-chain and a 1:1 comparison of contract mechanics isn't possible.

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.
