The figure and its period. Apple's Q1 fiscal-2026 Form 10-Q, filed January 30, 2026, reports research-and-development expense of $10.9 billion for the three months ended December 27, 2025, against $8.3 billion in the comparable year-ago quarter the same filing shows.
Burn rate, and the slope just steepened. A roughly one-third year-over-year increase in quarterly R&D is a larger step than Apple's recent annual growth would imply on a straight-line basis. The quarter suggests the engineering option is being funded faster, consistent with a heavier push into silicon and on-device intelligence.
An option, priced in cash. R&D at this run-rate, annualized, points to a full-year figure above the $34.5 billion Apple reported for fiscal 2025 — though a single quarter is not a guarantee. The disciplined read is to treat the Q1 step-up as a signal of intent and watch whether subsequent quarters confirm the new pace.
Discipline on what the line withholds. A 10-Q reports R&D as one consolidated, unaudited quarterly expense; it does not allocate the spend by program. The $10.9 billion is the quarter, and any breakdown into AI versus silicon versus future hardware is inference, not disclosure.
The long-horizon read: Apple's engineering burn accelerated to start fiscal 2026, and the curve is the thing to track. The primary record is the sec.gov 10-Q; figures verified through EdgarBeast, the SEC filing data API & evidence index.
