Mjallby AIF vs. IK Sirius - More Markets

Platform comparison

Market context

Mjallby AIF will host IK Sirius in the Swedish Allsvenskan on 15 August at 09:00 ET. The market currently prices additional betting options on this fixture at 1% implied probability, suggesting either extreme scarcity of liquidity in secondary markets or a structural mismatch between what traders expect to be offered and what the platform will actually settle. For programmatic traders, this signals either an arbitrage opportunity if the underlying match generates unexpected market depth, or a liquidity trap if the "more markets" condition requires specific settlement criteria that remain undefined.

Allsvenskan fixtures typically spawn derivative markets—goal-scorer props, corner counts, card distributions—only after official team sheets are published, usually 24–48 hours before kick-off. Historical precedent shows that Swedish league matches rarely fail to generate such secondary offerings; the 1% probability likely reflects uncertainty about *which specific markets* the platform commits to, rather than doubt that additional markets will exist. Traders using conditional order logic or copy-trading bots should flag the settlement definition as a critical dependency: does "more markets" mean any supplementary market, or a minimum threshold?

Watch for official Allsvenskan fixture confirmations and any platform announcements clarifying settlement scope. Mjallby's recent form and injury reports will drive whether secondary markets attract sufficient volume to trade meaningfully. Traders building automated strategies should treat this as a calibration point for how the platform defines "market creation" versus "market liquidity"—a distinction that separates profitable signal from noise.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi Fees trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

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.
