Market context
GAIS face Halmstads BK in Allsvenskan, and Polymarket currently prices the “More Markets” contract at **0% YES**, meaning the market is effectively saying there is no expected trigger for this ancillary settlement window on the current book. On Polymarket, that expectation is reflected through **USDC** positions on **Polygon**, with the contract resolving via **conditional tokens** when the stated outcome is or is not met.
Historical context points to a fairly balanced fixture rather than a one-sided mismatch. In the 17 recorded head-to-head meetings cited by FootyStats, GAIS have won 8 times and Halmstads BK 6 times, which suggests there is enough prior competitiveness to justify caution when reading a zero-priced side market as pure certainty.[1] For Polymarket users, that matters because “more markets” contracts often move on whether the game generates the specific extra conditions defined by the market, not simply on who wins.
The main catalysts are the same practical inputs that can still alter a low-probability book: late team news, lineup changes, weather, and any scheduling or settlement-language clarification from the market itself. Because the settlement window ends at 14:30 UTC, traders also need to watch whether the match starts on time and whether any relevant stats are confirmed by the official feed Polymarket uses for resolution. If no new information changes the pre-match setup, a 0% crowd-implied price usually signals that users see the conditional event as already very unlikely.

Methodology
This page reviews GAIS vs. Halmstads BK - More Markets across five venues. The live probability is the Polymarket mid-price, sourced directly from the on-chain Polygon order book; the comparison columns benchmark each venue on fee structure, KYC, settlement currency and payment rails. Every CTA routes to Kalshi UK, which mirrors the Polymarket order book at 0% fees.
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.
