Dota 2: RE.Arise vs Ilbirs eSports (BO3) - Asgard Championship Playoffs

Platform comparison

Market context

RE.Arise and Ilbirs eSports are facing off in a best-of-three lower-bracket playoff match, with the series effectively part of the tournament’s late-stage elimination path. Live listings show the game in progress and tied 1-1 in maps, which means the market’s 100% crowd-implied YES reading is already anchored to an in-play outcome rather than a pre-match view.[1][2][9]

The recent head-to-head is the clearest comparator for reading this contract. Polymarket’s own market note says RE.Arise beat Ilbirs 2-1 in the group stage on 1 August, while another match record shows RE.Arise also won a later meeting 2-0, suggesting a live series context where either side has already shown they can take maps off the other.[6][16][17] That matters because in BO3 Dota, a 1-1 scoreline leaves settlement exposed to a single deciding game, and prediction markets can reprice sharply once one side reaches match point.

Traders should watch for any schedule slip, disconnect protest, or admin ruling before the settlement window closes, because the contract resolves 50-50 if the match is cancelled, tied, or delayed beyond seven days without a winner.[Market description] The event is being tracked by multiple live score services, but the contract itself settles in USDC on-chain, so the relevant risk is not just who wins but whether a formal result is posted in time.[1][3][10] Broader crypto conditions are only secondary here, though BTC and ETH volatility can still affect collateral behaviour and liquidity on the venue if the market reprices late.

Methodology

This page reads Dota 2: RE.Arise vs Ilbirs eSports (BO3) - Asgard Championship Playoffs on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement. Kalshi (USD, off-chain), Betfair (GBP/EUR, off-chain) and Manifold (play-money) are listed alongside for venue context. Every CTA routes to BTC Prediction, which mirrors the Polymarket order book directly.

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.

What does a transaction cost on Polygon?

Polygon gas is typically under $0.01 per transaction. A full trade cycle (Approve + Order + Fill) totals around $0.03 — compared to $5-50 on Ethereum mainnet.

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%.
