Did the net cash from operating activities of Mastercard for the quarter ended September 30, 2026 come to at or above 47.5% of its revenue?
Divide the net cash from operating activities by the revenue that Mastercard reports for the quarter ended September 30, 2026 in its 10-Q or 10-K filing on SEC EDGAR. The answer is yes if the ratio is at or above 47.5%; no if it is below 47.5%.
If the source is late or silent: If Mastercard has not filed by November 16, 2026, or a filing restates a period the rule reads, the test is inconclusive, and the Result says what was read and what was missing.

If yes

Yes: strong collections and lower expense growth push the ratio up near last year's 56.6 percent level.

The thesis
Will the S&P 500 ex-financials aggregate trailing-twelve-month operating margin reported for Q4 2026 exceed the Q4 2025 level by at least 50 basis points?
Broad AI adoption in administrative, support, engineering and coordination work lowers opex per unit of revenue fast enough that aggregate index-level operating margins expand by at least half a point year over year, rather than being reinvested into headcount.
