Nebius has declared that, effective October 1, it will implement a sweeping price increase across several GPU cloud services, encompassing H100, H200, B200, and B300 models, with an average hike of around 20%. This move represents the second round of price adjustments since May of this year. Using the B300 as an illustration, the cumulative price rise has soared to approximately 56%. Triggered by this announcement and buoyed by NVIDIA's robust financial results, Nebius's stock price jumped nearly 7% in after-hours trading, while Coreweave's shares climbed nearly 4%, and the optical communications sector also witnessed a general uptick.

The primary catalyst for these price hikes is the tight supply-demand dynamics in the AI computing power market. Nebius has reported that its demand outlook now stretches beyond 24 months, with customers reserving computing power resources as far ahead as 2028. In recent times, Nebius has not only clinched sizable deals with major clients like Microsoft and Meta but has also garnered investment from NVIDIA. Consequently, its stock price has surged by roughly 150% year-to-date. Moreover, the disparity between computing power supply and demand has bolstered the bargaining clout of data center operators, with contract terms increasingly tilting in favor of the suppliers.
