Market context
Zachary Svajda and Denis Shapovalov were set for a Canadian Open first-round match on hard courts, and the market’s **42%** crowd-implied price for Svajda sits below most pre-match bookmaker and model views, which generally made Shapovalov the favourite. Recent prices showed Shapovalov around **-140 to -178** and Svajda around **+110 to +145**, while independent previews also leaned towards a Shapovalov win.[1][9][14][15]
For reading this market, the main comparison point is that the price is not asking whether Svajda is competitive, but whether he can beat the more established Canadian on home soil. In similar ATP first-round matchups, markets often move quickly on late fitness or withdrawal news, and the settlement terms matter: if the match is not completed, the resolution follows the advance result, while cancellation, a tie, or a delay beyond seven days falls back to **50-50** under the event rules.[2][11][13]
A trader should watch the official order of play, any schedule shifts from the tournament, and whether either player is reported injured, withdrawn, or rescheduled, because those are the catalysts most likely to change the outcome or trigger the fallback rules. On accessibility, “no-KYC up to $1,500” generally means a user can trade up to that threshold without identity verification, but larger activity will typically require KYC; for German users, GlüStV can affect whether access is permitted at all, and US-facing venues also face potential CFTC jurisdictional risk depending on how the market is offered and who can access it.[2][13]

FAQ
- How are winnings taxed?
- Tax treatment varies by jurisdiction. In most countries, prediction market gains are treated as ordinary income or capital gains. We cannot provide tax advice — consult a tax professional for your specific situation.
- Can I trade anonymously?
- Pseudonymously, yes — up to the KYC threshold. Polymarket Tax UK stores an email address and wallet addresses rather than a legal name. Over $1,500 lifetime volume triggers KYC, after which identity is no longer anonymous.
- What happens during a tax audit?
- You're responsible for documenting your trades. Polymarket Tax UK exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.
- Is there a withdrawal cap?
- No platform-side cap. You can withdraw any amount provided KYC is complete. SEPA bank withdrawals over €15,000 trigger additional anti-money-laundering checks (statutory obligation for all platforms).
- What if regulation changes?
- If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Tax UK would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
