Market context
Beijing's highest temperature on 16 August 2026 will be recorded at Capital International Airport Station and measured against historical August patterns in northern China. The settlement hinges on Weather Underground's Daily Observations table rather than summary figures, a distinction that matters when intraday peaks diverge from reported highs. The 0% crowd probability reflects either extreme confidence in a specific temperature band or minimal trading activity; either way, the book lacks depth until capital flows in through accessible deposit channels.
August temperatures in Beijing typically range between 26–32°C, with occasional peaks above 35°C during heat waves. The past decade shows 16 August specifically has recorded highs between 28–34°C in most years, though 2020 saw 36.2°C. Current probability positioning suggests traders are either heavily concentrated in a narrow range or the market has attracted insufficient liquidity to establish meaningful odds. Deposit friction—whether via Klarna's staggered payment schedules, SEPA transfers, or USDC on-ramps—directly affects whether new capital can enter and tighten spreads.
Traders monitoring this market should track China Meteorological Administration forecasts released in early August, which typically provide 10-day outlooks by early-to-mid month. Any announced heat advisory or unusual atmospheric patterns (monsoon shifts, high-pressure systems) would shift implied probabilities materially. Market depth will expand only if payment rails remain frictionless; Klarna's three-installment model and SEPA's next-day settlement both lower barriers to entry compared to traditional wire transfers, potentially unlocking the liquidity needed to move this market off zero.

UK Frequently Asked Questions
- What does SOFORT cost as a deposit method?
- Polymarket Klarna UK charges no fees for SOFORT. The only cost is the internal FX spread (typically <1%) on EUR→USDC conversion. SOFORT itself has no end-user fees — the platform absorbs acquirer costs.
- How fast is SEPA deposit?
- SEPA Instant: under 10 seconds. SEPA Standard: 1-2 business days. Both accepted fee-free; the internal USDC conversion runs automatically once EUR lands in the platform account.
- Can UK traders use Klarna to deposit on Polymarket?
- Polymarket does not natively accept Klarna. To fund a Polymarket account from the UK, you must first purchase USDC via a crypto exchange (Coinbase UK, Kraken) or Revolut, then transfer to a Polygon-compatible wallet. Some third-party on-ramps (MoonPay, Transak) accept UK debit cards and may support Klarna buy-now-pay-later for crypto purchases.
- What payment methods can UK users use for Polymarket?
- UK traders typically use: (1) Coinbase UK or Kraken — buy USDC with GBP debit card or bank transfer; (2) Revolut — buy crypto and send to wallet; (3) MoonPay or Transak — Visa/Mastercard UK debit card directly to USDC on Polygon. Standard GBP-to-USDC conversion fees range from 0.5–2.5%.
- How long do Polymarket withdrawals take for UK users?
- Polymarket withdrawals to your Polygon wallet are instant (on-chain). Converting USDC back to GBP via Coinbase UK or Kraken typically takes 1–3 business days for bank transfer, or near-instant for Revolut. Polygon gas fees are minimal (<$0.01 per transaction).
