Halmstads BK vs. IK Sirius - More Markets

Platform comparison

Market context

Halmstads BK and IK Sirius meet in an Allsvenskan fixture, and the “More Markets” contract is about whether Polymarket adds extra submarkets rather than the match winner itself. With the crowd-implied probability at 2% YES, the market is pricing a low chance of any new ancillary market being posted before the settlement window closes at 17:00 UTC, which is consistent with a narrow, event-specific listing rather than a broad menu of props.[19]

For comparable framing, this should be read against the pre-match price structure already visible in the underlying game: Sirius is the clear favourite in standard 1X2 books, with away-win odds around 1.41 and Halmstad priced near 6.50-8.20, while goal lines such as BTTS Yes and over 2.5 are also actively traded.[1][2][3] In practice, a power-user would treat 2% as a base rate for platform-side expansion, then monitor whether the match page gains new liquid instruments; historically, additional markets on football fixtures tend to appear only when there is enough time, data completeness, and exchange demand to support them, rather than because of the result on the pitch.[1][19]

The main catalysts are operational rather than sporting: any late schedule change, suspended market, or delayed feed can alter whether extra markets are created before settlement, and the key dependency is the event metadata becoming final enough for the venue to expose further props.[19] Traders running bots or conditional orders would watch the market page for new listings, check whether team news or line-up updates change the ancillary menu, and verify that the contract timestamp still sits ahead of the cutoff, because once the window closes there is no room for late additions.[1][19]

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 Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

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.
