In Q4'26, NVIDIA's operating cash flow reached $36.19B USD, marking a substantial increase from the previous quarter's $23.75B USD and reflecting robust operational performance. Free cash flow for the same period stood at $34.90B USD, up significantly from $22.12B USD in Q3'26, underscoring strong liquidity generation after accounting for capital expenditures. Over the period from Q1'24 to Q4'26, both operating and free cash flows exhibited a strong upward trend, with operating cash flow growing from $2.91B USD to $36.19B USD and free cash flow from $2.66B USD to $34.90B USD, driven by consistent quarterly gains amid NVIDIA's expansion in AI and computing sectors. Notable accelerations occurred in Q1'26 and Q4'26, where values more than doubled from prior lows, though minor dips in Q2'25 and Q2'26 highlight periodic volatility in capex or operational timing. The bar chart visualization emphasizes the parallel growth trajectories, with free cash flow consistently trailing operating cash flow by about 3-5% due to investments, positioning NVIDIA favorably for future scaling.
