Market context
Team Spirit, the 2022 International champions from Russia, face Xtreme Gaming of China in a best-of-three Group Stage fixture at The International 2024, scheduled for 13 August at 01:00 ET. The 38% implied probability for Team Spirit reflects their status as slight underdogs despite their major-tournament pedigree, suggesting the market prices Xtreme Gaming's recent form and regional strength as meaningful counterweights.
Historical precedent shows that Russian teams at The International have maintained competitive edges in early-stage matches despite geopolitical disruptions to their preparation cycles. Team Spirit's 2022 championship run and subsequent top-four finishes at subsequent Internationals establish a baseline expectation of consistency, yet Xtreme Gaming's Chinese roster has demonstrated improved coordination in regional qualifiers and mid-tier tournaments throughout 2024. The current probability discount for Team Spirit aligns with how prediction markets typically value recent tournament results over historical accolades when both teams arrive with comparable preparation time.
Traders should monitor official schedule confirmations from Valve, as The International Group Stage occasionally experiences delays due to technical issues or unforeseen circumstances—the settlement window extends to 2026-08-13 to account for potential postponements beyond seven days. Roster changes or last-minute substitutions, typically announced 24 to 48 hours before matches, can shift hero pool flexibility and team synergy. Watch for any official statements regarding player availability or team conditions released through The International's official channels or team social media accounts in the 48 hours preceding the fixture.

FAQ
- Do I need to KYC for Is Kalshi Legal in California?
- Not for lifetime trading volume under $1,500. Above that threshold, a quick KYC flow kicks in — ID, selfie, approximately 5-10 minutes. The threshold matches FATF travel standards for unregulated crypto platforms.
- 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.
- Are prediction markets gambling?
- Legally unclear in most jurisdictions. Some interpretations classify them as wagering (gambling regulation applies), others as derivatives (financial regulation applies). There's no global precedent specifically for on-chain prediction markets.
- 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), Is Kalshi Legal in California would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
