In brief
Polymarket gives a 10.5% chance that CME Crude Oil futures will exceed the all-time high of $147.27 by December 31, 2026, and a negligible 0.4% chance by September 30. Current WTI prices hover around $92, and recent news of a possible Saudi pipeline reopening has reduced supply fears, making a record unlikely in the short term.
Introduction
Oil markets have been volatile in 2026, driven by the ongoing conflict between the US/Israel and Iran, attacks on critical infrastructure, and fluctuating supply expectations. The Polymarket event “Crude Oil all time high by…?” asks whether the CME Group’s front-month Crude Oil (CL) futures will surpass the historic high of $147.27 on any trading day before the specified deadlines. As of September 24, 2026, the market assigns a 10.5% probability to a record by December 31 and a mere 0.4% by September 30. This article analyzes the current state of play and the factors that could shape the outcome.
What to know
The market resolves to “Yes” if the official daily high price for the Active Month of CME Crude Oil (CL) futures exceeds $147.27. The active month is the nearest contract month, switching two business days before spot expiration. Resolution data comes from the CME Group website.
As of September 23, 2026, West Texas Intermediate (WTI) crude oil closed at $92.10, with a daily high of $93.05 (Investing.com). This is far below the $147.27 threshold. The global benchmark Brent crude fell to about $98 a barrel on September 22 after reports that Saudi Arabia’s damaged East-West pipeline may soon reopen, allowing more oil to reach world markets (The New York Times). The pipeline had been shut down following a drone attack by Iranian-backed Houthi militia.
Earlier in September, oil prices had spiked above $107 (Brent) and $103 (WTI) after an Iranian ship was attacked in the Strait of Hormuz and the Saudi pipeline was damaged (Al Jazeera). The US has been working to clear Hormuz traffic, with more than 100 vessels passing daily before the war. The Energy Information Administration’s September 2026 Short-Term Energy Outlook forecasts world crude oil production to average 74.78 million barrels per day in 2026, down from 78.99 in 2025, reflecting supply disruptions (EIA).
Bank of America has warned that Brent crude could top $150 a barrel if Iran war disruptions persist (CNBC). However, the recent decline in prices suggests that markets are pricing in a de-escalation.
The market numbers
| Outcome | Implied Probability |
|---|---|
| December 31 | 10.5% |
| September 30 | 0.4% |
Total volume on the event is $4,153,924, with liquidity of $310,213. The market closes on January 1, 2027. The implied probability of “No” (no record by December 31) is approximately 89.1%.
The factors at play
- Geopolitical tensions: The war with Iran and Houthi attacks on Saudi infrastructure remain the primary upside risk. Any major escalation could disrupt supply through the Strait of Hormuz, potentially driving prices above $147.
- Saudi pipeline restart: Reports that the East-West pipeline may soon reopen have eased supply fears. If confirmed, this would add over 5 million barrels per day of capacity, reducing the likelihood of a price spike.
- US military presence: The US is actively clearing Hormuz traffic, which may deter further attacks and stabilize shipping.
- Global demand and production: The EIA forecasts lower world production in 2026 due to disruptions, but demand may also soften amid economic slowdown. The balance will influence price direction.
- Market positioning: Current futures prices are well below the all-time high, and the rapid decline from September highs suggests speculative froth has dissipated.
Our prediction
According to our analysis, the most likely outcome is December 31. Polymarket currently assigns a probability of 10.5%, while our internal estimate is 5%. The difference stems from the recent drop in oil prices and the potential reopening of the Saudi pipeline, which reduce the probability of a supply shock severe enough to push prices above $147.27. The September 30 outcome is virtually impossible given the current price level and the six-day window remaining.
Risks and uncertainties
- Escalation of the Iran conflict: A direct confrontation or blockade of Hormuz could send prices skyrocketing overnight.
- Further attacks on Saudi or UAE infrastructure: Additional drone or missile strikes could take more capacity offline.
- Unexpected supply disruptions: Technical failures, hurricanes in the Gulf of Mexico, or political instability in other major producers.
- Demand surge: A faster-than-expected global economic recovery could tighten the market.
- Resolution source delays: The market uses CME data; any delay in publication could affect resolution timing.
Conclusion
While the Polymarket event reflects a non-trivial chance of a new all-time high by the end of 2026, the current fundamental picture—with prices around $92, easing geopolitical tensions, and potential supply restoration—suggests the probability is lower than the market implies. The most likely scenario is that crude oil does not surpass $147.27 by December 31, making the “No” outcome the true favorite, but among the listed outcomes, December 31 remains the more plausible date if a spike were to occur.
