Expert US stock seasonal patterns and calendar effects to identify recurring market opportunities throughout the year. Our seasonal analysis reveals predictable patterns that have historically produced above-average returns. Goldman Sachs economists, led by chief economist Jan Hatzius, have analyzed nearly a century of data and concluded that technological advances — including the current AI wave — have historically correlated with rising corporate concentration in the United States. The report indicates that AI could accelerate this trend, benefiting dominant firms that invest heavily in intangible assets.

- Goldman Sachs' analysis uses long-term data on corporate income, sales, and tax records to track concentration trends since the 1930s.
- The bank observes that periods of faster technological change have historically coincided with sharper rises in corporate concentration.
- AI is characterized as a "technology shock" that could follow a similar pattern to previous innovations, potentially benefiting large incumbents.
- The report emphasizes investment in intangible assets — such as software, data, and intellectual property — as a key driver of concentration.
- The findings contrast with narratives that predict AI will democratize business opportunities for smaller competitors.

Key Highlights
A report published by Goldman Sachs this week examines whether the rapid adoption of artificial intelligence will disrupt the market position of today's leading companies or strengthen it. The investment bank's analysis leans toward the latter, based on long-term data on income, sales, and corporate tax records dating back to the 1930s.
"Corporate concentration in the US has steadily climbed since the 1930s, rising more rapidly during periods of faster technological change," wrote Jan Hatzius and his team. The historical lesson, they argued, is that new technologies and successful investment in intangible assets tend to reinforce the advantages of already dominant firms.
The report comes as investors and policymakers worldwide debate the broader economic implications of AI. While some anticipate a leveling effect as smaller firms gain access to advanced tools, Goldman’s findings suggest the opposite may occur, with large companies better positioned to absorb and deploy AI capabilities at scale.

Expert Insights
While Goldman's historical perspective does not offer specific predictions about future market dynamics, it suggests that AI may become another force reinforcing the market power of America's largest firms. Investors and corporate strategists may need to consider how these concentration trends could affect competitive landscapes across sectors.
The analysis implies that companies with deep resources for AI research, data collection, and infrastructure deployment could widen their moats relative to peers. Smaller firms, by contrast, might face structural barriers to capturing equivalent benefits from the technology.
From a policy standpoint, the report could add to debates around antitrust enforcement and regulation of AI. If concentration continues to rise, regulators may face pressure to address potential anti-competitive outcomes. However, the report itself does not prescribe any specific regulatory response.
Ultimately, Goldman's work highlights a recurring historical pattern: technological revolutions, rather than spreading wealth broadly, have often amplified the advantages of those already at the top. Whether AI breaks this cycle or reinforces it remains an open question, but the evidence presented suggests caution about expecting a more level playing field.
