Global Super League: Guyana Amazon Warriors vs San Francisco Unicorns

Platform comparison

Market context

Guyana Amazon Warriors versus San Francisco Unicorns is a Global Super League match in Providence that has already been listed as live on cricket score services, with the contest shown at 0/0 and market pages still reflecting a fresh or in-play state despite the scheduled July 23 slot. In a programmatic workflow, the cleanest way to handle a 100% crowd-implied YES is to treat it as an operational outlier: check whether the market is already effectively settled, whether the feed has rolled to a live result, and whether your bot or conditional-order logic should suppress new entries rather than treat the line as tradable signal.[1][8]

For historical framing, pre-match pricing on this fixture was not uniform: one preview had San Francisco Unicorns on a narrow 52% edge, while another tipped Guyana Amazon Warriors as favourites at 1.48, which is roughly consistent with a modest home-side lean rather than a dominant mismatch.[2][3][4] That matters because a 100% YES probability is far beyond those previews and is more likely to reflect market mechanics, a completed result, or a thin order book than genuine pre-match certainty. For tooling, that is the sort of case where copy-trading and automated fills need a hard validation step against the event status before mirroring sentiment.[2][3][4][8]

The main catalysts to watch are the official match result, any schedule slippage, and whether ESPNcricinfo’s scorecard has finalised the outcome, since the market resolves from that published result and counts ordinary on-field rulings such as DLS, DRS, over-rate penalties, or forfeits as wins. If the match was delayed, shortened, or completed with a tiebreak, that still resolves on the on-field winner, so a trader scanning for settlement risk should prioritise the scorecard state over pre-match previews or third-party prediction pages.[1]

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.

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.
