Market Analysis: 4 Key Themes Defining Markets in 2026
Key Takeaways
- Key themes in 2026 will be shifting geopolitics, AI’s investment leadership, energy and data center demand, and private credit liquidity risks.
- In their market analysis, investors can consider how these themes will interact with each other rather than just how each theme would act in isolation.
The last year in markets was shaped by tariffs, geopolitical shifts, and the AI boom. What can investors expect in 2026?
This infographic, created in partnership with MSCI, breaks down their expert market analysis for the year ahead. It highlights four key themes that are set to shape markets.
1. Geopolitical shifts continue
In 2025, geopolitical shocks tested confidence in U.S. leadership, prompting inflows into European defense stocks. At their year-to-date peak, European stocks had climbed 93% higher relative to America’s 43% jump.
Even after strong European returns, U.S. stocks were still priced much higher by year end.
| Price Ratio | Europe | U.S. | European Discount |
|---|---|---|---|
| Trailing Price-to-Earnings (P/E) | 32x | 44x | -28% |
| Forward P/E | 27x | 32x | -16% |
| Price/Book | 8x | 9x | -12% |

The U.S. remains a core market for investors seeking growth, but at a higher cost.
2. AI investment at scale
A major driver of U.S. stocks, and global markets more broadly, is AI.
Importantly, AI firms far outpace all other companies when it comes to investments and research. The below table shows investment rates as a percentage of revenues in November 2025.
| Firm Type | R&D Intensity | Capex intensity | Reinvestment rate |
|---|---|---|---|
| AI Firms | 11.0 | 9.8 | 30.6 |
| All Other Equities | 3.5 | 5.3 | 14.5 |

MSCI’s expert market analysis projects that this investment edge could lead to 20% higher earnings growth for AI firms in 2026.
3. AI’s power and data center boom
AI’s momentum is moving beyond Nvidia to data centers and energy.
| Segment | Projected Annual Growth Rate Through 2030 |
|---|---|
| Overall Electricity | 4% |
| Global Data Center Electricity | 15% |
| AI-Optimized Servers | 30% |
Source: IEA via MSCI, data published April 2025.
Through 2030, a market analysis by IEA projects that electricity demand for data centers and AI-optimized servers will grow substantially faster than the broader electricity market.
4. Private credit: growing but untested
A key source of AI funding is private credit, which has seen a recent shift to semi-liquid funds that offer periodic withdrawals.
This shift is creating tension between liquidity promises and multi-year loans, which may intensify if write-downs continue to rise. The following table shows the percentage of loans flagged for a potential 50% loss over time.
| Date | Mezzanine Loans | Senior Loans |
|---|---|---|
| 2020-06-30 | 8.9% | 6.3% |
| 2020-09-30 | 7.0% | 6.0% |
| 2020-12-31 | 4.7% | 1.2% |
| 2021-03-31 | 4.7% | 1.8% |
| 2021-06-30 | 3.7% | 1.4% |
| 2021-09-30 | 6.8% | 2.1% |
| 2021-12-31 | 5.1% | 2.3% |
| 2022-03-31 | 7.1% | 2.8% |
| 2022-06-30 | 9.4% | 2.1% |
| 2022-09-30 | 6.0% | 2.7% |
| 2022-12-31 | 7.1% | 3.2% |
| 2023-03-31 | 7.4% | 2.9% |
| 2023-06-30 | 7.0% | 2.6% |
| 2023-09-30 | 8.3% | 3.0% |
| 2023-12-31 | 7.3% | 2.1% |
| 2024-03-31 | 8.1% | 5.0% |
| 2024-06-30 | 8.5% | 6.1% |
| 2024-09-30 | 12.7% | 4.8% |
| 2024-12-31 | 11.9% | 4.4% |
| 2025-03-31 | 11.3% | 4.9% |
| 2025-06-30 | 13.3% | 6.5% |
Source: MSCI. Senior loans: Lower-risk debt with first right to repayment. Mezzanine debt: Mid-tier, higher-risk debt that sits between senior loans and equity; often convertible to equity.
Since 2021, the proportion of mezzanine loans flagged for a potential 50% loss has more than tripled. These write-downs are raising questions about whether semi-liquid funds can withstand mounting credit quality and liquidity pressures.
