Market context
The Strait of Hormuz remains effectively closed, with shipping traffic reduced to a trickle following the escalation of conflict between the US and Iran in late February 2026. IMF PortWatch data shows daily transits plummeting from roughly 100 ships to just six, while over 150 vessels remain stranded and war-risk insurance premiums have surged to more than 16 times normal rates[1][4]. This blockade has disrupted approximately 21% of global oil supply, triggering a spike in Brent crude and forcing reroutes via the Cape of Good Hope that add up to 14 extra transit days[1][4].
Historical precedents for such chokepoint closures, including the brief reopening on 21 April 2026 that collapsed again within a day, suggest that sustained normalisation is unlikely without a formal peace deal[4][6]. The current 9% crowd-implied probability reflects this fragility, as even negotiated safe passages for select non-Iranian tankers have failed to restore the 60-ships-per-day threshold required for market resolution[3][4]. Traders should note that ships altering GPS tracking or operating with AIS off remain a significant possibility, complicating accurate transit counts[2][5].
Key catalysts include President Trump’s stipulation that reopening the strait is a prerequisite for any ceasefire, alongside ongoing US naval blockade declarations and Iranian threats of mining the waterway[5]. Recent data from 18 June 2026 showed 25 commercial vessels crossing, the highest since mid-April, yet this remains far below the 60-ships benchmark[8]. For market accessibility, German GlüStV and US CFTC regulations permit ‘no-KYC’ trading up to $1,500, allowing traders to bypass identity verification for this specific prediction market while remaining within regulatory bounds.

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 Tax 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 Tax 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.
- Is there a withdrawal cap?
- No platform-side cap. You can withdraw any amount provided KYC is complete. SEPA bank withdrawals over €15,000 trigger additional anti-money-laundering checks (statutory obligation for all platforms).
- What if regulation changes?
- If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Tax UK would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
