According to Apple's most recent financial report, in the March quarter of 2026, its research and development (R&D) expenditure constituted 10.3% of its total revenue. This marks the inaugural instance in at least three decades where this ratio has surpassed 10% within a single quarter, underscoring the iPhone manufacturer's heightened emphasis on artificial intelligence. In comparison to the preceding quarter's 7.6% and the 9% from the same period a year prior, this indicates a substantial escalation in R&D investment. During this timeframe, the company's revenue experienced a 17% year-on-year upswing, representing the swiftest single-quarter growth since 2021. Nevertheless, R&D spending soared by nearly 34% year-on-year, roughly double the rate of sales expansion.
