In brief
Polymarket traders currently assign an 81% probability that WTI crude oil will touch $75 in August 2026, and a 77% chance of hitting $80. Our analysis, based on recent geopolitical events and market data, broadly agrees with the $75 probability but sees room for a slightly higher chance of $80 due to persistent supply risks.
Introduction
As of August 9, 2026, the WTI crude oil market is heavily influenced by the aftermath of the U.S.-Iran war and ongoing negotiations to reopen the Strait of Hormuz. Polymarket's prediction market offers a unique window into trader expectations for the month, with outcomes ranging from $65 to $110. This article dissects the current odds, the key drivers, and our reasoned outlook.
What to know
West Texas Intermediate (WTI) crude oil is the primary U.S. oil benchmark. The Polymarket event asks which price levels WTI will hit during August 2026. The market is a multi-outcome event, meaning multiple contracts can resolve to 'Yes' if the price touches that level at any point in the month.
Recent news has been a rollercoaster. After a sharp drop in early August, prices have stabilized. According to Bloomberg, oil slid to a three-week low as optimism grew for a U.S.-Iran agreement. Reuters reported a 7% drop after President Trump cancelled an attack on Iran to pursue a nuclear deal. However, as of August 7, The Hill reported that U.S. crude supplies are at a 45-year low, adding upward pressure.
Negotiations between Iran and Oman, reportedly awaiting Iranian parliamentary approval, face significant hurdles. Ts2.tech notes the agreement confronts 'several hurdles such as US-imposed blockades, resistance from Iranian hardliners, and vessel limits.' Meanwhile, City Index observes that 'Hormuz tensions keep geopolitical risk premiums elevated.'
Looking ahead, CNBC notes that investors who profited from the Iran war's oil boom face a 'trickier' trade going forward. Oilprice.com reports that Citi has raised its Q3 Brent forecast to $80/barrel, citing the 'U.S.-Iran war drags on.'

The factors at play
- Geopolitical tensions in the Middle East: The U.S.-Iran war and the status of the Strait of Hormuz are the dominant factors. A diplomatic breakthrough would likely send prices lower, while a breakdown could spike them.
- U.S. crude inventories: At a 45-year low, domestic supply is tight, providing a price floor. Any further decline in stockpiles would be bullish.
- Federal Reserve policy: The swaps market now sees a 30% chance of a rate hike in September, down from 58% (Source 14). Weaker labor data has reduced rate hike expectations, which is supportive for oil (weaker dollar, stronger demand).
- Demand concerns: While not currently dominant, a global economic slowdown or recession could cap price gains. Polymarket puts recession odds below 10% (Source 11).
- Houthi attacks and Russian supply: Houthi missile strikes on Saudi tankers and Ukrainian drone attacks on Russian infrastructure add sporadic supply risk premiums.
Our prediction
According to our analysis, the most likely outcome is ↓ $75. Polymarket currently assigns a probability of 81.0%, while our internal estimate is 85.0%. The difference stems from the fact that current spot prices are around $78 (Source 8), and the tight supply situation makes a dip below $75 a relatively low-probability event. The high probability (81%) already reflects the market's view that oil trades in a wide range. However, we believe the ongoing geopolitical risks and very low inventories make it slightly more likely that oil will touch $75 than the market currently prices, especially given the possibility of diplomatic progress that could push prices temporarily lower.
We also see the ↑ $80 outcome as highly likely (our internal estimate: 82% vs. market 77%), given the same supply tightness and headline risk.
Risks and uncertainties
- Successful Iran deal: If negotiations succeed and the Strait of Hormuz fully reopens, prices could fall sharply, potentially hitting $70 or even $65.
- Escalation of conflict: A new military engagement in the Middle East could send prices above $100.
- Federal Reserve surprise: If the Fed hikes rates by 50 bps or more, a demand shock could push oil below $75.
- Data error: Polymarket liquidity, while substantial, is not infinite. A large trade could temporarily move odds.
Conclusion
The WTI crude oil prediction market for August 2026 reflects a market pricing in a significant geopolitical risk premium. While a move to $75 is seen as very likely, the core distribution is anchored around the mid-to-high $70s. Traders should monitor the Strait of Hormuz negotiations and U.S. inventory data as the month progresses.
