Dota 2: Team Falcons vs GamerLegion (BO3) - The International Group Stage

Platform comparison

Market context

Team Falcons and GamerLegion meet in a best-of-three at The International group stage, with the market leaning to Falcons at 80% implied probability. That sits broadly in line with the setting: Falcons are the defending champions and opened the event with a 2-1 win over LGD Gaming, while GamerLegion have already shown they can take series at the event, including a 2-0 over Xtreme and a 1-2 loss to Vici Gaming on 14 August. [15][3][5]

For a Swiss-stage Bo3, the main read is that the market is pricing Falcons as the more stable side, but not invincible. Early TI results have already been volatile, and in this format a single upset can shift pairing strength quickly across the remaining rounds. A price near 80% generally implies Falcons are expected to win more often than not, yet still leaves room for GamerLegion to convert if draft edges, side selection, or momentum from earlier rounds matter more than raw team reputation. [5][8][15]

The key catalysts are straightforward: whether the match begins on schedule, whether there is any rescheduling within the market’s deadline, and whether the published round order changes before the settlement window closes at 08:00 UTC. The broader crypto backdrop is also relevant for USDC-settled markets, with BTC and ETH funding rates in positive territory and open interest still elevated, which can affect risk appetite and flows across prediction-market positions even when the esports event itself is unchanged.

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

What are crypto prediction markets?

Crypto prediction markets are on-chain smart contracts where you buy YES or NO shares on a future crypto event (e.g. "BTC above $100k by year-end"). The market price between 0¢ and 100¢ is the implied probability.

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.

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%.
