Farsi, Hengam, Hormuz or Kharg Island no longer under Iranian control by 2026?

Platform comparison

Market context

Iran’s grip on these islands is rooted in long-standing sovereignty and security arrangements, not a fast-moving territorial dispute. Farsi Island is a tiny Iranian naval outpost, restricted to civilians and home to an IRGC Navy base, while the 1968 agreement on sovereignty explicitly recognised Iranian control of Farsi and Saudi control of nearby Al-Arabiyah[1][2][13]. Kharg, Hormuz and Hengam sit within Iran’s wider Gulf military and energy geography, with the set of islands historically tied to monitoring shipping lanes rather than being subject to routine transfer of control[15]. Against that backdrop, a 2% crowd-implied chance of one island passing out of Iranian hands by late September reads as a tail-risk outcome, not a base case.

The market is leaning on an abrupt security or war catalyst, but the resolution rules exclude temporary raids, isolated landings, sabotage, offshore naval activity and mere claims that control has changed[11]. That makes scheduled diplomacy or political statements far less relevant than a verified change in primary governmental or military control on the ground. Recent reporting has focused on the islands’ strategic role in the Strait of Hormuz, with renewed attention after U.S. strikes and broader regional tension, but that is still a very different proposition from an internationally backed authority actually taking and holding one of the islands[15]. Traders should watch for credible conflict reporting, formal transfer or ceasefire terms, and any authoritative news that an outside force has established durable control; absent that, the market structure points strongly to No[11].

Methodology

Political prediction markets differ structurally from sports betting: thinner liquidity, longer settlement windows, higher sensitivity to single news events. This page shows the live Polymarket quote for Farsi, Hengam, Hormuz or Kharg Island no longer under Iranian control by 2026? plus platform attributes for the three reference venues, so you can see at a glance where the deepest market for this question sits.

Resolution & payout

Political markets typically settle on official candidate or agency confirmation. Polymarket uses UMA Optimistic Oracle: a proposer posts the outcome with a bond, the two-hour window opens, then the smart contract pays USDC.

Kalshi settles USD via CFTC clearinghouse, with clearly defined resolution sources (e.g. AP race calls for elections). Betfair settles after the official outcome is registered with the league or agency. Manifold is play-money.

UK Frequently Asked Questions

How accurate are political prediction markets?

Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.

What resolution source is used for elections?

Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.

Which platform has the deepest political liquidity?

Polymarket — by far. US 2024 presidential volume was ~$3.5B vs Kalshi (~$200M) and Betfair (~$120M). Where Polymarket is geo-blocked, brokers like Trump Prediction route into the same order book at 0% fees.

Are political prediction markets legal in my country?

It varies. They sit in legal gray areas in most jurisdictions. Polymarket is geo-blocked from US/UK/EU; some broker frontends have a different geo footprint. Trade only with capital you can afford to lose, and only if you understand the legal status in your jurisdiction.

Are UK election prediction markets available from the UK?

Yes. Betfair Exchange and Smarkets offer UKGC-regulated UK election markets (seat counts, party share, constituency results). Polymarket also lists UK election contracts with deeper global liquidity. Betfair winnings are typically tax-free for UK individuals; Polymarket profits are subject to HMRC CGT.
