Stuttgart Open: Ben Shelton vs Sho Shimabukuro

Platform comparison

Active sub-markets

Market context

Polymarket currently prices Ben Shelton's advancement at 47% on USDC via Polygon conditional tokens, implying roughly even odds in what shapes as a second-round Stuttgart Open encounter scheduled for 12 June 2026. The American, son of former world number one Bryan Shelton, faces Japan's Sho Shimabukuro in what would be a grass-court clash at the ATP 250 event. Settlement occurs 7 days post-scheduled match time, with cancellation or delays beyond that window triggering a 50-50 resolution.

Shelton's recent trajectory offers the primary historical lens. The 21-year-old broke into the ATP top 100 in 2024 and has shown volatility across surfaces, with grass representing neither his strongest nor weakest terrain. Shimabukuro, ranked considerably lower, has competed sporadically at ATP level and typically appears in qualifying draws. Head-to-head records between players at this ranking differential rarely exist; comparable second-round matchups at Stuttgart between a rising American and a lower-ranked Japanese player have historically favoured the higher seed, though upsets materialise at roughly 35-40% frequency on grass at this tournament level.

Traders should monitor ATP injury bulletins through early June, as both players' fitness status in the fortnight before Stuttgart will shift probability meaningfully. Weather forecasts for Stuttgart on 12 June may influence play style expectations. Any withdrawal announcements from either player, or unexpected seeding changes following the draw release, would trigger immediate repricing on the conditional token market.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

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.

What does it cost to trade on Polymarket Scam??

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

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.

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.
