Market context
Ships are moving in and out of the Persian Gulf again, easing oil prices after weeks of near-standstill traffic caused by the Iran war. The Strait of Hormuz, which carries roughly 20–30% of global oil consumption daily, saw a sharp recovery over the weekend of July 6–7, with 29 vessels passing on Saturday and 12 on Sunday, though this remains well below the 74 ships recorded earlier in the week [4][5]. This volatility frames the current 85% YES probability on Polymarket: traders are betting that IMF Portwatch will finalize a total transit count that meets the market’s threshold, despite the recent drop following weekend attacks.
Historical patterns show that Hormuz traffic can swing dramatically within days depending on geopolitical developments. In April 2026, inbound voyages were just three while outbound reached six, illustrating how quickly flows can contract [1]. By mid-June, outbound commercial traffic had halted entirely for 72 hours, creating a severe bottleneck before resuming after an interim deal was signed [2][6]. The current probability reflects confidence that the recovery trend will hold through July 12, but traders must watch for any new announcements from Iranian or US technical teams implementing the peace deal, as delays or reversals could abruptly halt transits again [8].
On Polymarket.za.com, this contract trades in USDC on Polygon using conditional tokens, where the 85% price implies a high likelihood of a “YES” outcome based on finalized IMF Portwatch data. Key catalysts include daily Kpler and MarineTraffic updates, which have already shown sharp drops post-attacks, and any official statements on the interim peace deal’s implementation [5][7]. Since data must be finalized before settlement—meaning the next day’s point must be available—traders should monitor the release schedule closely, as late finalization could delay resolution even if the count is clear.
