Claim: Oil prices dropped more than 4% in a single day as the US and Iran approached a peace deal

The claim that oil prices dropped more than 4% in a single day as the US and Iran approached a peace deal is mostly true. Reports indicate that oil prices fell significantly, with Brent crude dropping by 8.3% and WTI by 8.9% following news of a potential peace framework. Mainstream sources support this, highlighting the impact of geopolitical developments on oil prices. However, some may dispute the exact percentage drop, as certain reports indicate a 4% decline under different circumstances, which could create confusion about the claim's accuracy. The models diverge sharply — treat this as higher-uncertainty. OpenAI comes in highest (80%), while Gemini is lowest (50%). OpenAI expresses higher confidence than Gemini on this claim. While the evidence supports a significant drop in oil prices, the exact percentage varies across sources. Some reports indicate a drop of over 8%, while others mention a 4% decline. This discrepancy does not fundamentally alter the overall trend of falling prices due to geopolitical factors but introduces uncertainty regarding the precise figures. Therefore, while the claim is largely supported, the variation in reported percentages suggests a need for caution in interpretation.
