Outlook for today
There is no major company-specific event for Marathon Petroleum scheduled for September 21, 2026 in the latest investor and earnings calendar overviews, but the stock remains sensitive to movements in crude benchmarks and refined product margins. As Wall Street Week Ahead noted in a summary of market conditions around the September 18, 2026 close, Brent crude traded near USD 103 per barrel and WTI near USD 100 to USD 107, levels that continue to underpin refining economics. Broader macro events this week, including discussions on Middle East energy risks at the United Nations and ongoing volatility in oil prices, could influence sentiment in US refining stocks such as Marathon Petroleum as today’s session approaches.
