Mjallby AIF vs. IK Sirius - More Markets

Platform comparison

Market context

Mjallby AIF will host IK Sirius in the Swedish Allsvenskan on 15 August 2026. The market's 11% implied probability for "more markets" reflects trader expectations that additional betting options will become available for this fixture before the settlement deadline at 13:00 UTC.

Historical precedent suggests that Allsvenskan matches routinely generate expanded market offerings as kickoff approaches. Domestic Swedish football fixtures typically see secondary markets—such as correct-score, player performance, or in-play propositions—added within 48 hours of match day, particularly for top-tier league contests. The low current probability may indicate either sparse historical data on this specific matchup or trader scepticism that the platform will populate additional markets given the relatively modest profile of both clubs in the Swedish top flight. Comparable fixtures between mid-table sides have shown variable market expansion, with some drawing only standard 1X2 and total-goals options.

The catalyst for market movement will be the platform's scheduling decisions and any announcements regarding fixture coverage. Traders should monitor whether Mjallby and Sirius generate sufficient liquidity or promotional interest to justify expanded offerings. The settlement window closes just hours after the scheduled 09:00 ET kickoff, leaving minimal time for late-stage market additions. Any platform statement about Allsvenskan coverage depth or fixture prioritisation in early August could shift expectations materially.

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 Mjallby AIF vs. IK Sirius - More Markets 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

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.

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.

What resolution source is used for elections?

Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.

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.

Why do Polymarket and Kalshi differ on elections?

Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.

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.
