Combined average of Moat (AI Resilience), Growth, and Valuation scores.
Moat Score
A global duopoly with Moody's in debt ratings. Regulatory and brand moat.
S&P Global operates a Financial Toll Bridge:
- Regulatory Oligopoly: You cannot issue global debt without a rating from S&P or Moody's. It is a legally-embedded requirement for institutional investors.
- IP Moat: The S&P 500 brand is the most licensed index in the world. Asset managers pay SPGI every time a new ETF is created.
- Low Capex: Once the rating methodologies and data platforms are built, every additional dollar of revenue flows straight to the bottom line.
Moat Verdict
S&P Global's regulatory moat (NRSRO status) and role as the definitive system of record for credit risk makes them uniquely AI-resilient. AI disrupts analysis, not the legal requirement to use S&P ratings.
94.2 resilient · 65.0 vulnerable · 80/20 = 88.3 · + 2 strength · = 90
Open a moat to read its note.
Rating nomenclature (AAA, AA+…) is written into mandates, ISDA agreements and capital rules, but that is the legal embedding already rated under regulatoryLockIn and systemOfRecord, not a separate learned-interface moat. Re-rated from strong to intact so one fact is not scored three times.
Credit rating methodologies are proprietary, regulatory-recognized, and legally required — AI enhances but cannot replace the NRSRO designation.
Capital IQ, Platts and filings aggregation are a large curated corpus now being licensed into AI platforms, but Capital IQ competes head-on with Bloomberg and FactSet on the same public filings. Re-rated from strong to intact. On October 27, 2026 S&P opened a strategic review, including a possible separation, of Capital IQ and associated data businesses; if it goes ahead, most of what this pillar describes leaves the company.
SEC-recognized credit analysts, regulatory relations specialists, and 160-year institutional knowledge cannot be replicated.
Ratings plus Capital IQ, Platts and Indices is a real cross-sell, but each piece competes on its own and the Mobility spin-off narrowed it further; the bundle raises switching cost without being category-defining. Re-rated from strong to intact. The October 27, 2026 Capital IQ review would narrow it again if it ends in a separation; RatingsDirect and RatingsXpress are expected to stay.
160 years of credit ratings history, Platts energy commodity benchmarks, and proprietary financial data — legally embedded in markets.
SEC-recognised NRSRO status, plus capital, insurance and fund rules that reference recognised ratings. The licence is a moat because it has held: roughly 94–95% of all outstanding credit ratings sit with S&P, Moody's and Fitch (SEC annual staff report on NRSROs), and S&P is the largest of the three. Entrants since Dodd-Frank (Kroll, DBRS Morningstar, Egan-Jones) failed to take material share.
Two-sided: issuers need the rating investors demand, and investors demand it because issuers carry it — most large corporate bonds carry both S&P and Moody's ratings. The loop is why roughly 94–95% of all outstanding credit ratings sit with S&P, Moody's and Fitch (SEC annual staff report on NRSROs) a decade and a half after regulators tried to open the market.
Rating references in bond covenants, loan agreements and fund mandates are real switching friction, but it is the same legal embedding rated strong under regulatoryLockIn and systemOfRecord, and S&P does not sit in the payment layer. Re-rated from strong to intact.
The authoritative reference for credit risk that mandates, capital calculations and index eligibility defer to. With roughly 94–95% of all outstanding credit ratings sit with S&P, Moody's and Fitch (SEC annual staff report on NRSROs), downstream systems have no alternative record; S&P also owns the benchmark record in indices (S&P 500).
Scale here is the two-sided network itself, already rated under networkEffects; crediting it again as a cost lead would double-count the same evidence.
Franchise reputation matters but is inseparable from the regulatory standing and relationships rated elsewhere; not credited twice.
Moat in 5–10 years
The ratings duopoly holds: NRSRO status, the issuer-investor loop and the credit system of record have kept roughly 94–95% of outstanding ratings with the big three since Dodd-Frank, and nothing in view moves that share within a decade. Private credit and smaller agencies are the pressure to watch, but S&P is rating that market too. The intact pillars hold, and AI pressure on analyst work is already charged through the AI split rather than as a trend.

Growth Score
Q3 2026 (reported October 27, 2026) grew continuing-operations revenue 7% YoY to $3,678M, with adjusted operating margin 53.5% (+60bps) and adjusted diluted EPS +9% to $4.58. The mix flipped from Q2: Indices kept growing, +20% to $554M at a 72% adjusted margin (asset-linked fees +24%), but Ratings slowed to +2% at $1,271M (transaction revenue +1% to $677M, non-transaction +4% to $594M; adjusted margin 66%), after +13% in Q1 and +17% in Q2. Market Intelligence grew 7% to $1,263M (36% adjusted margin) and Energy 6% to $645M. Full-year 2026 guidance was raised: organic constant currency revenue growth 7.5-8.5% (from 6.0-8.0%) and adjusted diluted EPS $17.70-17.95 (from $17.50-17.75), with buybacks still above $7B. The same release opened a strategic review, including a possible separation, of Capital IQ and associated data businesses, most of Kensho Data & Platforms inside Market Intelligence; RatingsDirect, RatingsXpress and Enterprise Solutions are expected to stay. No timetable, and guidance assumes Market Intelligence stays as it is.
Valuation Score
Re-marked at the $466.55 close on October 30, 2026 (the mark for the 2026-11-02 rebalance): 67 on the unchanged $355 / $475 / $565 ladder, from 65 at the $476.00 mark. Only the price moved; the ladder and the thesis are not re-underwritten here. Re-marked at $476.00 intraday on October 27, 2026, up about 5.6% on the Q3 beat, the raised guide and the Capital IQ review: 65 on the unchanged $355 / $475 / $565 ladder, from 70 at the $450.31 close on October 23. The ladder is held: the guide rose by $0.20 at both ends, about 1%, which does not move a 12-24 month base by itself, and the Capital IQ review is not a transaction yet. At $476 the stock is about 26.7x the $17.83 midpoint of FY2026 adjusted EPS guidance and sits on the base target, so the price now assumes the review delivers value or Ratings returns to growth. Earlier context: the scenario targets were rebased to post-spin RemainCo after the July 1, 2026 Mobility Global distribution, and the stub has risen since it separated from a $424.42 cum-distribution close on June 26.

Growth Analysis
Growth Drivers
Key Risk
Ratings stalled in Q3 2026 (+2%) after the issuance surge, which is now observed and charged in the Ratings driver. The unmaterialised half is Indices: asset-linked fees (+24% in Q3) fall with equity levels, so a drawdown while issuance is still soft would leave both benchmark segments flat at once. The Capital IQ review adds to it: a separation would remove the largest block of subscription revenue left after the Mobility spin, the part that kept growing in Q3 while Ratings did not.
Score Derivation
72.9 base − 1.0 trajectory + 4 margin − 5 risk = 71
Base 72.9 (8-12% revenue CAGR, midpoint 10%) + 0 trajectory (Indices stable at +20% for two quarters against Ratings decelerating; Market Intelligence & Energy back to stable; "Operating Margin" is a margin line held stable and scored once, below) + 4 expanding margin (Q3 2026 adjusted operating margin 53.5%, +60bps; FY2026 adjusted margin expansion guide raised to 75-100bps) − 5 moderate issuance/AUM cyclicality risk, graded alongside MCO = 72

Where We Are vs Targets
Loading live price…
Issuance rolls over and equity markets fall together, hitting the two segments that now carry the growth, and RemainCo de-rates to ~20x post-spin earnings.
- Debt issuance normalises after the 2026 refinancing surge, unwinding the +25% Ratings transaction revenue growth reported in Q2 2026
- An equity drawdown cuts asset-linked Indices fees, which compound off the $6.35T ETF-linked AUM base rather than a contracted one
- Market Intelligence stays at the +6% pace and Energy at +3%, leaving no ballast when the cyclical half turns
RemainCo delivers the guided $17.50-17.75 and holds a multiple in line with Moody's as the post-spin mix shifts revenue toward the two highest-margin, most defensible segments.
- FY2026 adjusted diluted EPS lands in the guided $17.50-17.75 range, +10-12% on the pro forma 2025 base
- Indices sustains high-teens growth as ETF-linked AUM compounds off $6.35T and net inflows exceed $600B annually
- Over $7B of 2026 buybacks compounds per-share earnings on a shrinking count
The mix shift is recognised in the multiple: a company where Ratings and Indices supply nearly all the growth at ~70% segment margins is priced as an index-and-benchmark franchise rather than a diversified data conglomerate.
- Private credit ratings scale into a standing requirement as insurer and NAIC frameworks mature, extending Ratings growth past the refinancing wall
- Market Intelligence re-accelerates out of the post-realignment trough, removing the drag on blended growth
- The market re-rates RemainCo toward the index-franchise multiple, closing the gap to MSCI on a comparable mix
