ITF Roehampton: Charles Broom vs Oliver Tarvet

Platform comparison

Market context

Charles Broom’s clash with Oliver Tarvet in Roehampton is being priced as a near-certain Broom result, with the crowd market at 100% for Broom and the bookmaker screen pointing in the same direction. Cloudbet’s match-winner line of 1.42 for Broom versus 2.85 for Tarvet implies a Broom win probability in the low 70s before margin, while BetVictor listed Broom at 1.30 in the same event, which is even shorter and broadly consistent with a clear favourite. TennisStats also shows Broom ahead on 2026 and trailing only slightly in recent hard-court form, while the live match feeds from TennisTemple and Sofascore indicate Broom was ahead in the completed match state reported there.[5][17][10][2][6]

The historical frame matters because there is no head-to-head record between them, so traders are leaning more on ranking and surface form than on direct matchup evidence.[1][8] Broom’s higher ATP standing and stronger season-long win profile make him the more established player, but Tarvet’s recent Roehampton run and the fact that these are ITF-level matches mean volatility is still higher than at ATP Tour level.[1][10][15] In that context, a 100% YES crowd price leaves almost no room for uncertainty, and any surprise would likely come from event-specific disruption rather than from a large statistical edge for Tarvet.

The main catalysts to watch are straightforward: whether the match is actually completed within the settlement window, whether the official result is posted cleanly, and whether any scheduling change pushes it beyond the 7-day cut-off, which would force a 50-50 resolution under the market rules. Flashscore and TennisTemple both show the match in Roehampton on 9 August, while sportsbook and stats pages are already displaying the encounter as finished, so the key issue for settlement is administrative confirmation rather than on-court uncertainty.[3][2][9][11] If the match was started but not formally completed in the record set used by the market, the contract’s abandonment rule becomes the decisive factor.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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

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 does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

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 Best Prediction Markets 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.
