PGA Tour: 3M Open Top 20

Platform comparison

Market context

The 3M Open begins at TPC Twin Cities in Blaine with the field set and four rounds to decide who lands inside the top 20, including ties. PGA Tour and tournament listings show the event runs 23–26 July 2026, with an $8.8 million purse and 500 FedExCup points on offer, which matters because a strong opening round can rapidly move a player from the middle of the pack into top-20 range. [1][4]

An **81%** crowd-implied yes price is high by the standards of a finish-position market, so the market is leaning towards a broadly favourable setup rather than a dramatic upset narrative. The closest comparable framing is that top-20 markets are usually more stable than outright-winning markets, because they allow for a wider band of acceptable outcomes; the result often turns on whether an established player simply avoids a bad round rather than needing to contend for the title. The pre-event field announcement also points to depth rather than a thin draw: organisers said the 144-player field included 53 of the top 125 in the Official World Golf Ranking, which supports the idea that the market is pricing a credible chance of a respectable finish rather than a longshot surge. [3]

For traders, the key catalyst is the tournament itself: tee times, early scoring and any withdrawal or injury news between now and Sunday will matter more than pre-event commentary. CBS Sports’ live leaderboard and PGA Tour coverage make clear the event is already under way on the scheduled 23–26 July window, so the main dependency is where the listed player sits after the first two rounds, when top-20 probabilities typically reprice fastest. If official final results are delayed, the market’s settlement rule also gives it a hard backstop, with no resolution after 1 August at 8:00pm ET. [2][4]

Methodology

This page tracks PGA Tour: 3M Open Top 20 across four political prediction venues. Live odds come from the Polymarket order book (the deepest political prediction-market book). Kalshi is the CFTC-regulated US alternative, Betfair the established UK sports-exchange with politics markets, Manifold the open play-money variant. For users geo-blocked from Polymarket directly, brokers like Election Predictions UK provide a 0%-fee route into the same order book.

Resolution & payout

Political markets typically settle on official candidate or agency confirmation. Polymarket uses UMA Optimistic Oracle: a proposer posts the outcome with a bond, the two-hour window opens, then the smart contract pays USDC.

Kalshi settles USD via CFTC clearinghouse, with clearly defined resolution sources (e.g. AP race calls for elections). Betfair settles after the official outcome is registered with the league or agency. Manifold is play-money.

FAQ

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 Election Predictions UK 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.

Which political events have the biggest volume?

US Presidential election, party nominations (DNC/RNC), Senate majorities, individual state outcomes (Pennsylvania, Michigan, Wisconsin), and major European elections. Peak markets reach $50-500M per event.
