Is SPGI a Buy? What to Consider in 2026
Last updated June 2026
Short answer
There is no universal answer to whether SPGI is a buy; it depends on your thesis, time horizon, and what you already own. Below is the case for S&P Global, the main risks to weigh, where the stock trades, and a framework to decide for yourself. This is informational, not a recommendation, and Walnut is not an investment adviser.
S&P Global is a financial-information and analytics company best known for two franchises: S&P Global Ratings, one of the big three credit-rating agencies, and S&P Dow Jones Indices, which owns benchmark stock indices including the S&P 500 and the Dow Jones Industrial Average. The company makes money from rating debt issuances (a fee tied to bond issuance activity), licensing its indices to ETFs and funds (collecting fees on the assets that track them), and selling market data, analytics, and commodity-price benchmarks. Its Market Intelligence segment provides data platforms and research to financial professionals, and S&P Global Commodity Insights (formerly Platts) sets energy and commodity price benchmarks. The 2022 merger with IHS Markit broadened its data, automotive, and analytics offerings. S&P Global benefits from durable, recurring, subscription-like revenue and high margins. Headquartered in New York City, it serves banks, asset managers, corporations, and governments worldwide.
The case for S&P Global
1. Index licensing and passive investing.
S&P Dow Jones Indices earns fees from ETFs and funds that license its benchmarks, including the dominant S&P 500. As assets continue shifting toward passive index investing, the asset base tracking S&P indices grows, lifting licensing revenue. This is a high-margin, asset-linked royalty stream that compounds with markets and fund flows over time.
2. Credit ratings and a wide moat.
S&P Global Ratings is one of three agencies that dominate global credit ratings, a business protected by regulation, reputation, and the fact that issuers need ratings to access debt markets cheaply. Ratings revenue rises with bond-issuance volumes. The oligopoly structure and high barriers to entry give the franchise durable pricing power and strong margins.
3. Recurring data, analytics, and Market Intelligence.
A growing share of revenue comes from subscriptions to data platforms, research, and analytics serving financial professionals, plus commodity-price benchmarks from Commodity Insights. The IHS Markit merger expanded these recurring, non-cyclical streams, reducing dependence on issuance-linked ratings revenue and improving the predictability of overall results.
4. Pricing power and capital return.
High switching costs and entrenched benchmarks give S&P Global consistent pricing power. The company converts a large share of revenue into free cash flow and returns capital through steady dividend growth and share buybacks, making it a long-running compounder favored in quality-oriented portfolios.
The risks to weigh
Ratings revenue is cyclical and tied to debt-issuance volumes, which fall when interest rates rise sharply or credit markets freeze. Regulatory scrutiny of the rating-agency oligopoly is a recurring risk, including potential reforms to how ratings are paid for or used. The index business depends on continued passive-investing inflows and faces fee pressure as competitors and ETF issuers push for lower licensing costs. Integration of IHS Markit and ongoing acquisitions carry execution risk. The stock typically trades at a premium valuation, so any slowdown in issuance, fund flows, or data-subscription growth can compress the multiple meaningfully.
Valuation context (as of early 2026)
- Revenue (TTM): ~$14 billion
- Revenue growth: high-single-digit to low-double-digit
- Operating margin: ~45% on an adjusted basis
- Recurring revenue mix: the majority of revenue is subscription or asset-linked
- Free cash flow: ~$5 billion annually
- Dividend: decades of consecutive increases, a Dividend Aristocrat
- P/E (TTM): ~35x, a premium multiple
S&P Global trades at a premium valuation that reflects its wide moats, high margins, and durable recurring revenue. The qualitative profile is a high-quality compounder: oligopoly ratings, dominant indices, and growing data subscriptions. The premium multiple leaves the stock sensitive to slowdowns in bond issuance or passive-fund inflows.
How to decide for yourself
Rather than asking whether SPGI is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold SPGI indirectly through an index or sector ETF before adding more.
