Falcons vs. Colts

Platform comparison

Market context

The Falcons’ preseason visit to the Colts was scheduled for Saturday 22 August at 1:00 pm ET at Lucas Oil Stadium, and the game has already been completed with Atlanta winning 34-6. That makes the current 100% YES crowd price consistent with a settled, one-sided outcome rather than an unresolved live-event risk.

For prediction markets, the nearest comparable read is a completed contest with no remaining postponement or tie pathway, which usually collapses residual uncertainty quickly once the final score is posted. In USDC-settled on-chain markets, that means the only thing left is resolution timing rather than price discovery: once the oracle or market operator has the official result, the contract should move to Falcons, with no scope for a 50-50 fallback unless the game had been cancelled or finished level.

The main catalysts for traders were the scheduled kickoff, confirmation that the fixture stayed on the calendar, and the official final whistle; after that, the trade is effectively an operational settlement event. More broadly, any broad risk-on or risk-off move in BTC and ETH can affect platform liquidity and wallet flows, but it does not alter the underlying NFL result, so the only material dependency here is the market’s data feed and final settlement process.

Methodology

Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — sit alongside as off-chain reference points so you can see how the contract translates across regulatory and settlement regimes.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

UK Frequently Asked Questions

Why USDC and not ETH or USDT?

USDC is the Polygon standard — audited reserves (Circle, monthly attestation), deepest order book, low gas costs. ETH volatility would distort probability quotes; USDT has thinner Polygon liquidity than USDC.

Can I use Bitcoin directly?

No, Polymarket operates exclusively in USDC on Polygon. You can bridge BTC to USDC via an exchange or bridge service and deposit on Polygon — typically 10-30 minutes processing time.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
