Market context
Iran has conducted direct military strikes against Arab states on two occasions in recent years: ballistic missile and drone attacks on Iraq in January 2020 (following Soleimani's assassination) and on Israel in April 2024 (following Israeli strikes on Iranian consular facilities in Damascus). The 0% crowd probability reflects the absence of an imminent trigger event comparable to those precedents. Historical patterns suggest Iranian strikes follow specific provocations—typically Israeli or US actions perceived as existential threats to Iranian interests or personnel. Without a catalysing incident of similar magnitude, the baseline expectation remains low through the August 2026 settlement window.
Traders monitoring this market should track developments in three areas: direct Israeli military operations against Iranian targets or proxies in Syria and Iraq; announcements regarding US military posture in the Gulf; and escalation dynamics within Lebanon involving Hezbollah, which Iran uses as a primary proxy force. Recent reporting from Reuters and regional security analysts indicates Iranian leadership has signalled restraint following the April 2024 strikes, citing domestic economic pressures and international isolation. Programmatically, this market rewards conditional order logic—setting triggers tied to specific geopolitical announcements rather than time-based positions. A trader might construct alerts monitoring Israeli Defence Force statements, US Central Command activity reports, or Lebanese military developments, then execute positions only when those conditions activate.
Methodology
We track Will Iran target a Arab country on 2026? across the five venues with material prediction-market liquidity. The probability shown is the live Polymarket mid; the comparison rows summarise how each venue treats the underlying contract — fees, KYC thresholds, settlement currency, deposit options. The highlighted row marks the cheapest route into Polymarket's order book.
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.
- What's the difference between YES and NO shares?
- A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
- 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%.
