Roehampton: Peter Makk vs Marcus Walters

Platform comparison

Market context

Peter Makk and Marcus Walters are scheduled to compete in the Roehampton qualifying tournament on 18 August 2026. The match forms part of the ATP qualifying draw for the grass-court event held in south-west London. Settlement hinges on whether Makk progresses past Walters in a single-elimination format, with the window closing on 25 August to account for potential delays or rescheduling.

The 100% implied probability reflects the absence of public information suggesting either player's withdrawal or a scheduling conflict. Qualifying matches at established ATP venues rarely fail to proceed as scheduled; cancellations typically occur only in cases of injury, illness, or extreme weather. Historical data from Roehampton and comparable grass-court qualifiers shows completion rates above 98% when both players are confirmed in the draw. The current pricing suggests traders are treating this as a near-certainty to be contested.

Traders should monitor ATP official announcements regarding draw confirmation and any player injury bulletins in the weeks preceding the event. Makk and Walters' recent form on grass surfaces and head-to-head records, if available, would inform the underlying match outcome but do not affect settlement unless the match fails to occur. The settlement window extends seven days beyond the scheduled date, providing buffer for rain delays common on British grass courts. Any announcement of withdrawal or postponement beyond 25 August would trigger the 50-50 resolution clause.

Methodology

Political prediction markets differ structurally from sports betting: thinner liquidity, longer settlement windows, higher sensitivity to single news events. This page shows the live Polymarket quote for Roehampton: Peter Makk vs Marcus Walters plus platform attributes for the three reference venues, so you can see at a glance where the deepest market for this question sits.

Resolution & payout

For political markets the resolution source is decisive. Polymarket defines a concrete source per contract (e.g. AP, Reuters, official electoral commission) and uses the UMA Optimistic Oracle as the on-chain dispute mechanism. With a clearly defined outcome the USDC payout lands within minutes of the final confirmation.

UK Frequently Asked Questions

How accurate are political prediction markets?

Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.

Can prediction markets influence election outcomes?

Markets reflect expectations rather than create them. Studies show public-facing markets can anchor expectations, but don't influence the underlying outcome. Political markets are information, not advocacy.

Which platform has the deepest political liquidity?

Polymarket — by far. US 2024 presidential volume was ~$3.5B vs Kalshi (~$200M) and Betfair (~$120M). Where Polymarket is geo-blocked, brokers like Trump Prediction route into the same order book at 0% fees.

How fast do political markets react to news?

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

Are UK election prediction markets available from the UK?

Yes. Betfair Exchange and Smarkets offer UKGC-regulated UK election markets (seat counts, party share, constituency results). Polymarket also lists UK election contracts with deeper global liquidity. Betfair winnings are typically tax-free for UK individuals; Polymarket profits are subject to HMRC CGT.
