Makerfield by-election Winner

Market context

Makerfield is due to hold a parliamentary by-election in 2026 after the announced resignation of incumbent Josh Simons, and the market currently prices Andy Burnham at about 66% to win. That level implies a clear favourite, but not a done deal: on Polymarket the comparable contract is quoted in binary probability terms, while on venues such as Betfair or Smarkets the same contest is usually read through decimal prices and commission, which can make the lead look narrower or wider depending on fees and liquidity. In practice, a 66% favourite is still the kind of price that can move sharply on candidate selection, turnout expectations and any local polling or canvass evidence.

The closest frame of reference is a contest where Labour’s hold is being tested by Reform’s strength rather than a straightforward two-way safe-seat defence. Recent market reads have shown Burnham ahead but not dominant, with one listing putting him around 57.5% and Reform’s Robert Kenyon near 39%, while Polymarket has also seen separate prices on Burnham-related victory margins clustered around the teens. That split suggests traders are weighing not just outright winner risk, but whether the margin is comfortable or visibly damaged, which is often where books diverge first when information arrives unevenly.

The main catalysts are the formal by-election timetable, candidate confirmations, and any local or regional polling that clarifies whether Reform can convert national momentum into a constituency win. ITV reported on 20 May that Nigel Farage had visited Makerfield and described the contest as “the biggest in half a century”, underlining how much attention the seat is drawing. Traders should also watch for campaign launches, any Labour organisation around Burnham, and whether turnout assumptions change as the campaign date firms up. On platforms with broader access and lighter KYC friction, prices can react faster to headline-driven flows; on more regulated books, the same news may be reflected more slowly but with tighter spreads.

Methodology

This page compares Makerfield by-election Winner specifically across Polymarket, Kalshi, Betfair Exchange and Smarkets. Live odds come from the Polymarket order book; the other venues' contract details are maintained manually because their APIs aren't directly comparable. Every CTA routes to PolyGram, which mirrors the Polymarket order book at 0% fees.

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). PolyGram routes every trade directly into Polymarket's on-chain settlement, which is why payouts land fastest.

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 PolyGram?

Zero. PolyGram 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.
