Market context
The 2026 Open Championship at Royal Liverpool will crown the golfer who secures the Claret Jug, with Scottie Scheffler installed as the favourite to defend his 2025 title. Traditional bookmakers like BetVictor list Scheffler at 4/1, implying a 20% chance, while the prediction market in question shows a lower 11% implied probability for the specific listed player, suggesting a divergence in how risk is priced compared to decimal odds on platforms like Betfair or Smarkets.
Historical precedent shows that major golf winners often defy pre-tournament favourites, with the last five Open champions including three players outside the top two in betting odds. This volatility frames the current 11% probability as potentially undervalued if the market underestimates the field’s depth, whereas Kalshi’s fee structure and KYC requirements might deter traders seeking the same liquidity found on Polymarket’s permissionless interface, where odds are often more sensitive to late form.
Traders should monitor Scheffler’s schedule confirmation and any injury updates before the tournament begins, as elimination rules trigger immediate “No” resolutions for listed players. Recent reports confirm Scheffler is targeting a second consecutive win, but his form in the weeks leading to July remains the primary catalyst [1]. Watch for course-specific performance data from the Scottish Open, which often acts as a precursor to Open Championship success, and note that unlisted winners resolve the market to “Other”, a nuance less common on traditional sportsbooks.
Methodology
We read PGA Tour: The Open Championship Winner from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live mid is the canonical probability; the side-by-side columns benchmark fees, KYC, settlement currency and deposit rails so you can choose the venue that fits your jurisdiction and trade size.
Resolution & payout
Settlement is the biggest difference between the four platforms: Polymarket on-chain in USDC (instant), Kalshi USD via CFTC (T+1), Betfair and Smarkets in local currency via bank withdrawal (T+1 to T+3). On-chain settlement clears in minutes — the fastest payout path of the four.
FAQ
- What does Polymarket cost vs Kalshi?
- Polymarket: 0% fees, only Polygon network costs (~$0.01/trade). Kalshi: up to 7% per trade plus spread. For high-frequency traders, Polymarket is dramatically cheaper.
- Which platform has the deepest liquidity?
- Polymarket — by a wide margin. Top markets reach $50-500M volume, Kalshi ~$200M cumulative, Betfair similar. Deeper liquidity means your trade moves the quote less.
- Is Betfair a Polymarket alternative?
- Only partially. Betfair Exchange is UK-focused with a sports-betting emphasis; they have politics markets but with thinner liquidity than Polymarket. Settlement in GBP/EUR, 2-5% commission on winnings.
- What about Smarkets as an alternative?
- Smarkets is a UK betting exchange with a lower default commission (2%) than Betfair. Liquidity on political markets is below Polymarket, comparable to Kalshi. Geo-blocked in many jurisdictions.
- Which platform supports Klarna/SOFORT?
- Directly: none. Polymarket accepts only USDC on Polygon. Robinhood Prediction Markets offers a fiat on-ramp via Klarna or SOFORT (DE/AT/CH) and converts internally to USDC for the Polymarket order book. T+1 processing.
