S&P Global's upcoming October 27 earnings release will reveal Q3 2026 Ratings segment revenue, with analysts projecting total company revenue near $3.41–3.63 billion. Ratings performance hinges primarily on debt issuance volumes, which drove 25% year-over-year growth in Q2 transaction revenue to $746 million amid steady corporate refinancing and a stabilized rate environment. Non-transaction revenue grew 8% to $593 million in the same period, supporting overall segment expansion near 13–20% in recent quarters. Market-implied odds on Polymarket reflect trader consensus on issuance trends, with key variables including Treasury yields, credit spreads, and macroeconomic data releases ahead of the print. Historical patterns show Ratings often exceeding expectations during periods of sustained borrowing demand.
