US equity markets experienced a positive trading session on Friday, September 11, 2026, as investors processed new Consumer Price Index (CPI) data. Despite the major indexes having recorded losses over the previous four days, the Dow Jones Industrial Average, S&P 500, and Nasdaq Composite all posted gains. However, the market’s movement was heavily influenced by the latest inflation figures, which strengthened expectations that the Federal Reserve will raise interest rates in the coming weeks.
Market Performance and Inflation Data
On Friday, the Dow Industrial Average (^DJI) and the tech-heavy Nasdaq Composite (^IXIC) both climbed approximately 0.9% to 0.98%, respectively. Meanwhile, the S&P 500 (^GSPC) increased by 0.8% to 0.9%. This positive movement marked a turnaround after the indexes had been declining throughout the week.
The CPI report revealed that overall prices increased by 3.4% year-over-year in August, matching economic forecasts and remaining unchanged from the previous month’s reading. On a month-over-month basis, prices rose by 0.4%, also aligning with expectations. Crucially, when excluding volatile food and energy costs—a reading favored by the Federal Reserve—the CPI showed a rise of 0.3%, which was slightly higher than the 0.2% predicted.
This data prompted traders to intensify their predictions regarding future monetary policy. According to the CME’s FedWatch tool, market expectations indicate an 87% probability that the Federal Reserve will increase interest rates by 25 basis points during the Federal Open Market Committee (FOMC) meeting next week. This represents a significant jump from the 72% probability recorded just one day earlier, and 50% the prior week.
Energy Prices and Economic Concerns
The energy sector presented mixed signals. Diesel prices surged, crossing a record high of $6.05 per gallon on Friday, marking a sharp increase from $3.70 a year earlier. Leading crude benchmarks also saw movement, with Brent crude futures (BZ=F) hovering near $105 per barrel after falling from previous highs, while US WTI crude (CL=F) recovered and surpassed the $100 per barrel mark.
These energy price movements, coupled with persistent inflation, kept economic focus high. Consumer sentiment, according to a preliminary survey from the University of Michigan, declined to 47.8 in September, down from 51.7 the previous month. Furthermore, while the 12-month inflation expectation rose to 4.6% from 4% the prior month, the volatility in energy markets remains a concern for consumers.
Corporate and Tech Highlights
Several major companies reported significant developments. Oracle (ORCL) stock gained 4% in extended trading after reporting that sales in its cloud infrastructure division jumped 121% to $7.4 billion. This figure surpassed the average analyst expectation of $7.19 billion.
In other technology news, SpaceX CEO Bret Johnsen stated that the company is making progress toward its goal of reaching $100 billion in Annual Recurring Revenue (ARR). Johnsen reported that a recent hosting agreement would translate into approximately $1.11 billion monthly revenue starting December 1st, contributing roughly $13 billion to the overall ARR target.
Separately, Nvidia CEO Jensen Huang reiterated his optimistic forecast regarding the artificial intelligence market, predicting that its size will reach between $3 trillion and $4 trillion by the year 2030. He emphasized the continued growth of the semiconductor industry, driven by new computing applications and the advancement of AI models.
International Trade and Policy
On the international front, Saudi Arabia announced that it had closed its vital East-West oil pipeline following attacks that occurred on Thursday and Friday. This closure helped moderate the decline in crude oil futures. Furthermore, Canadian Prime Minister Mark Carney stated that Canada remains prepared to negotiate a beneficial trade arrangement with the United States, despite recent escalating economic tensions.
The market remains keenly attuned to the actions of global central banks, setting the stage for critical policy decisions next week.
