2025 Year in Review: AI Infrastructure and the Global Equity Resurgence
BY Paul A. Bodnar
CM Wealth Chief INVESTMENT officerEquities in the United States finished 2025 at historical peaks, capping a three-year stretch of performance for the S&P 500 that ranks among the top seven in the index's history. While the year was initially clouded by the introduction of "Liberation Day" tariffs and a subsequent spring correction, the market transitioned into a comprehensive "everything rally." By year-end, every major asset category had achieved positive results—a feat not seen since the immediate post-pandemic recovery.
Market Performance: A Global Rotation
For the first time in two decades, international markets outpaced American benchmarks as investors sought growth beyond domestic borders. This shift occurred after a volatile start to the year; the implementation of new trade barriers in early April triggered a 16.5% decline in developed world stocks and drove the U.S. dollar to its most severe first-half drop in fifty years. However, the markets demonstrated significant resilience, bottoming out in the spring before staging a massive recovery. The S&P 500 ended the year up 17.9%, remarkably surging 38% from its April lows as new trade agreements helped calm fears of a sustained inflationary spiral.
Global leadership was bolstered by significant fiscal support in Japan and Europe, while Foreign Developed (EAFE) stocks climbed by approximately 31.2%. Emerging Market equities were the standout regional performer, gaining 34.4% in dollar terms, fueled by a 100.7% explosion in Korean shares following domestic corporate reforms. In the final quarter, the S&P 500 maintained a steady pace, advancing roughly 2.7% despite the disruption caused by the nation's longest government shutdown, an unclear picture of the labor market, and mounting questions about AI returns.
The most dramatic gains of 2025, however, were concentrated in precious metals:
Gold and Silver: This sector mimicked the volatility of "meme stocks" to reach heights not seen since 1979. Silver led the market with a massive 149.1% return, while gold climbed 65% as central banks moved to diversify their reserves.
The AI Industrial Revolution
The domestic narrative remained centered on an artificial intelligence infrastructure race of historic proportions. The "Magnificent Seven" tech leaders and Broadcom now represent 40% of the S&P 500’s total value, more than doubling their collective footprint over the last decade. However, the rally’s breadth was notably thin within this elite group; despite their overarching influence, only two of these eight technology titans actually managed to outperform the broader S&P 500 index for the year.
Economically, the AI buildout served as the primary growth engine for the country. Data center construction and related capital spending contributed an estimated 1.1 percentage points to U.S. GDP growth in 2025. Remarkably, during the first six months of the year, this single investment cycle was responsible for nearly all observed economic expansion, even surpassing the contribution of traditional consumer spending.
Strategic Outlook for 2026: Navigating the "Jobless Expansion"
Entering 2026, the outlook remains fundamentally constructive, anchored by a unique "jobless expansion" where AI-driven productivity gains are expected to propel corporate earnings, even as the labor market cools. Goldman Sachs identifies a "friendly" environment for equities, underpinned by the dual tailwinds of stimulative federal tax policy and the Federal Reserve’s ongoing interest-rate normalization. Similarly, JP Morgan anticipates a global convergence in growth, forecasting a narrowing of the performance gap between the mega-cap technology leaders and the broader market.
Key pillars of this 2026 projection include:
The "BBB" Fiscal Catalyst: A central driver for 2026 is the One Big Beautiful Bill (BBB), which is expected to inject an estimated $150 billion in federal tax refunds into the economy. These refunds—primarily driven by enhanced standard deductions—should democratize the "wealth effect" that was largely concentrated among the top 1% in 2025, providing a vital lift to broader consumer sentiment and retail activity.
Resilient Infrastructure Spending: While investor scrutiny regarding ROI has intensified, we do not anticipate an AI "capex cliff" in 2026. Technology capital expenditure is forecast to reach $533 billion this year, marking a robust 33% year-over-year increase from the record levels in 2025.
Sector Rotation and Reflation: As the U.S. dollar stabilizes and international fiscal stimulus feeds through, we expect earnings to accelerate in sectors closely tied to the real economy, including Banks, Healthcare, and Materials.
Monetary Policy and Inflation: Although core inflation remains stubbornly above target, cooling housing costs are projected to help it drift toward a 2.2% to 2.4% range. Consequently, futures markets reflect a high probability of at least two additional rate reductions by the close of 2026.
The primary threat to this thesis is the potential for a more precipitous deterioration in the labor market. Additionally, throughout 2025, consumer-facing industries navigated significant headwinds as tepid hiring dampened confidence and rising tariff costs pressured margins. However, the synergistic impact of substantial fiscal stimulus and the structural shift toward AI-driven productivity suggests a resilient, upward path for diversified portfolios in the year ahead.
