Market context
Iran has already shown that it can move from throttling to near-zero connectivity quickly, so the practical question is not whether the state *can* impose a blackout, but whether it will again do so before settlement. Historical comparables are stark: nationwide cut-offs were documented in November 2019, during the January 2026 protests, and again from late February 2026 during wartime conditions, with monitoring groups and reporting describing traffic collapsing to around 1% or less of normal levels for extended periods.[7][8][11][16][17] For a programmatic approach, that history matters because the market’s settlement rule is mechanical: a six-hour run at or below the Cloudflare threshold is enough, so an automated watcher on the Cloudflare Radar bytes chart is more useful than trying to infer sentiment from headlines.[1]
The main catalysts are political and security decisions rather than ordinary network faults. Traders should watch for renewed domestic unrest, arrests, protest waves, military escalation, and any formal messaging from Iranian authorities about “security” or “temporary” communications limits, because those have preceded past outages.[1][3][13] Recent reporting in 2026 described internet restrictions as part of both protest suppression and wartime response, with access falling to about 1% of pre-war levels and shutdowns persisting for weeks or months.[11][14][15][17] For a copy-trading or conditional-order workflow, the useful signals are not price ticks but event triggers: sudden traffic collapse, ISP route withdrawal, and any coordinated nationwide restriction affecting both mobile and fixed networks.[4][8]
Methodology
This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket Review UK, which mirrors the Polymarket order book directly.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
UK Frequently Asked Questions
- Where can I trade this market with the lowest fees?
- Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Polymarket Review UK. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.
- Is this market available outside the US?
- Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
- 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%.
