In Q1'26, Roblox's total operating expenses reached approximately $1.44B USD, with R&D expenses at $422M USD and SG&A expenses surging to $1.02B USD, marking a significant escalation primarily driven by the latter category. From Q2'23 to Q1'26, operating expenses exhibited a consistent upward trend, growing from $442M USD to $1.44B USD, reflecting steady increases in both R&D (from $315M USD to $422M USD) and SG&A (from $127M USD to $1.02B USD) components. R&D showed moderate, linear growth with minor fluctuations, such as a slight dip in Q4'24, while SG&A accelerated sharply after Q2'25, contributing to the overall 226% rise and highlighting potential scaling pressures in administrative and sales functions. This stacked bar chart underscores R&D's stable dominance in earlier periods, shifting to SG&A's outsized impact in the latest quarter.
