Market context
Kharg Island remains the critical oil terminal for Iran, handling roughly 90% of the nation’s crude exports and serving as the primary source of state revenue. Despite recent US military strikes targeting Iranian facilities on the island in March 2026, Iranian control over the terminal has not been broken, and oil exports continue uninterrupted. The market’s 2% probability reflects the extreme difficulty of displacing Iran from this strategic asset without a full-scale invasion, which would face significant legal and humanitarian hurdles given the 8,000 civilians residing there[1][4].
Historically, comparable cases of territorial displacement in the Persian Gulf, such as the 1980s conflicts or the 2003 Iraq invasion, required overwhelming force and clear international mandates to alter control. The concentration of Iran’s export infrastructure on Kharg creates a high-stakes vulnerability, yet the island’s defensive integration and the geopolitical cost of seizing it have prevented any successful occupation to date[2][3]. This context suggests that the current low probability is well-founded, as no state has yet demonstrated the capacity or willingness to assume primary control over the island.
Traders should monitor official announcements from the US administration regarding potential blockades or occupations, particularly any moves linked to reopening the Strait of Hormuz, as revealed by Axios in recent reports[4]. Dependencies include the outcome of ongoing diplomatic negotiations and the level of international backing for any military action, which would be essential under international law to justify attacks on civilian infrastructure[1]. The settlement window ending in March 2026 leaves little time for a major shift in control, making the catalysts for change both urgent and uncertain.
From a regulatory perspective, this market operates under the German GlüStV framework and US CFTC reach, with 'no-KYC up to $1,500' allowing accessible participation for retail traders without stringent identity verification. This accessibility does not alter the factual reality that Kharg Island remains firmly under Iranian control, and the low probability reflects the substantial barriers to any change in sovereignty.

FAQ
- Is Polymarket legal in my country?
- Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Polymarket Legal UK has a different geo footprint.
- 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.
- Can I trade anonymously?
- Pseudonymously, yes — up to the KYC threshold. Polymarket Legal UK stores an email address and wallet addresses rather than a legal name. Over $1,500 lifetime volume triggers KYC, after which identity is no longer anonymous.
- What happens during a tax audit?
- You're responsible for documenting your trades. Polymarket Legal UK exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.
- 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.
