Market context
Yakult Brothers are playing Zero Tenacity in a best-of-three Dota 2 series in Games of the Future Group C, and the market is now close to the scheduled settlement window. On the exchange side, the crowd has pushed Yakult Brothers to an extreme **0% YES** price, which is the sort of move that usually reflects a stale or fully discounted outcome rather than a balanced pre-match read; by contrast, a separate prediction market for the same fixture showed Yakult Brothers around 65% before play, underscoring how quickly market-implied probabilities can diverge when liquidity is thin or one result has already been absorbed into pricing.[20][15]
The historical frame is straightforward: these teams met in February 2025 in a BO3 and Yakult Brothers won 2-0, while a current bookmaker-style preview still leant towards Yakult Brothers taking the series, although it also flagged Zero Tenacity’s ability to take at least one map in BO3 play.[12][2] Live match trackers show the series as a Group C fixture starting at 14:00 UTC, and one results feed already records a 2-0 final for Zero Tenacity, which is material because this market resolves on the match winner unless the contract’s cancellation or abandonment rules are triggered.[7][4]
For traders, the main catalysts are operational rather than macro: whether the official bracket page, stream, or score providers confirm a completed result before the settlement deadline, and whether any delay, replay, or administrative correction appears in tournament coverage.[7][3] If the result stands, the on-chain USDC payout should follow the normal market resolution path; if the match was not completed or is deemed invalid under the rules, the 50-50 fallback becomes relevant. Broad crypto conditions are less important here, though BTC and ETH volatility can still matter indirectly through exchange risk appetite and USDC capital rotation.
Methodology
This page reads Dota 2: Yakult Brothers vs Zero Tenacity (BO3) - Games of the Future Group C 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.
FAQ
- 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.
- 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.
- Which crypto markets exist on Polymarket?
- Currently active markets include BTC/ETH/SOL price targets, halving dates, ETF approvals, hard-fork outcomes and Layer-2 TVL thresholds. The list updates weekly; biggest volume sits on BTC and ETH price forecasts.
- Are crypto prediction markets taxable in the US?
- In the US, prediction market gains are typically treated as ordinary income or short-term capital gains depending on holding period. Consult a tax professional for your specific situation — we cannot provide tax advice.
