Combined average of Moat (AI Resilience), Growth, and Valuation scores.

90/100

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.

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.

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.
