As 2025 draws to a close, U.S. stock markets are navigating a final trading day marked by mixed premarket activity and lingering sentiment from a three-day losing streak, despite a year of robust overall gains. Investors are closing their books on a noteworthy year, with major indexes poised for significant annual advances, largely fueled by the relentless surge in artificial intelligence (AI) and technology sectors. Today, Wednesday, December 31, 2025, marks a full trading day for stocks, operating during regular hours from 9:30 AM ET to 4:00 PM ET, while bond markets will close early at 2:00 PM ET in observance of New Year's Eve. Markets will remain closed on Thursday, January 1, 2026, for the New Year's Day holiday.
Premarket Trading Activity and Futures Movements
Early Wednesday, U.S. stock futures showed a cautious tone. S&P 500 futures (ES=F) were down 0.28%, Nasdaq 100 futures (NDX) slipped 0.43%, and Dow Jones Industrial Average futures (DJIA) edged lower by 0.14% as of 4:00 a.m. EST. This continued a trend from Tuesday's regular trading, where all three major indexes closed lower for the third consecutive session. However, as the morning progressed, there was some fluctuation, with S&P 500 e-minis and Nasdaq futures reportedly up 0.1% each, and Dow futures flat around 8:59 a.m. EST. Other reports indicated Dow futures were 0.1% lower, S&P 500 futures 0.2% lower, and Nasdaq 100 futures 0.3% lower, reflecting thin trading volumes expected on New Year's Eve.
Among individual stocks making premarket moves, athletic apparel giant Nike (NKE) saw its shares rise 1.54% following news of a significant stock purchase by CEO Elliott Hill. Chipmaker Intel (INTC) also gained 1.34% in premarket trading. In the biotech sector, Autolus Therapeutics (AUTL) surged 5.35% after receiving a strategic upgrade from Needham & Co., which also lifted its price target for the company. Trump Media (DJT) shares also saw a premarket boost, gaining over 5%. Vanda Pharmaceuticals (VNDA) experienced a significant jump of 18.7% after the U.S. Food and Drug Administration approved its drug for the prevention of motion-induced vomiting.
Major Market Indexes: A Look Back at 2025
Despite the recent dip, the major U.S. market indexes are set to close 2025 with impressive annual gains. On Tuesday, December 30, the S&P 500 (SPX) fell 0.14% to 6,896.24, the Nasdaq Composite (COMP) declined 0.24% to 23,419.08, and the Dow Jones Industrial Average (DJIA) moved lower by 0.20% to 48,367.06. This marked the third consecutive day of losses for all three benchmarks.
However, the year-to-date performance tells a much brighter story. The Nasdaq Composite is on track for an annual gain of approximately 21%, while the S&P 500 is up around 17%, and the Dow Jones Industrial Average has climbed roughly 14% for 2025. The S&P 500 and the Dow are also set to record their eighth consecutive month of gains, marking their longest monthly winning streak since 2017. This strong performance has been largely attributed to an "insatiable appetite for AI stocks" that pushed all three indexes to record highs throughout the year.
Upcoming Market Events and Economic Data
With the year concluding, attention is already shifting to early 2026. The Federal Reserve's December 9-10 meeting minutes, released on Tuesday, revealed a divided debate among officials regarding the recent interest rate cut. While most participants supported lower rates, several suggested maintaining current levels. Despite this, expectations for further rate reductions in 2026 persist, with U.S. money markets pricing in a 17% chance of a January rate cut and a 53% chance of a March reduction.
On the economic data front, Initial Jobless Claims were released early on Wednesday, December 31, at 8:30 a.m. ET, coming in at 199,000, which was below the expected 220,000. This data suggests a labor market that is slowing but not in a state of collapse, a factor likely to influence future Fed policy decisions. Looking ahead to January 2026, key economic releases include the ISM Manufacturing report on January 5, followed by the ADP National Employment Report, Global Supply Chain Pressure Index (GSCPI), ISM Non-Manufacturing, and JOLTS on January 7. The Employment Situation report is scheduled for January 9, with the Consumer Price Index (CPI) on January 13 and the Producer Price Index (PPI) on January 14. The U.S. Bureau of Economic Analysis (BEA) is also slated to release the U.S. International Trade in Goods and Services for October 2025 on January 8, 2026, and an updated estimate for Gross Domestic Product (GDP) for the third quarter of 2025 on January 22, 2026.
