AMD reported strong second-quarter results and an upbeat outlook, betting heavily on its new Helios rack systems and Instinct MI400-series GPUs to drive future growth, yet investors reacted by sending its shares sharply lower. CEO Lisa Su told analysts that data-centre revenue is expected to more than double in 2027 as Helios and MI450-series deployments scale up, but Wall Street's unease centres on how concentrated that growth is among a small number of AI customers whose own profitability remains unproven, exposing AMD to any deflation of the broader AI investment boom.

Q2 profits jumped 163 percent year-on-year to $11.5 billion in revenue, with multi-gigawatt Helios commitments already secured from OpenAI, Anthropic and Meta, yet shares fell around 10.5 percent on the announcement and were still down 8.7 percent from the opening price shortly after. Su acknowledged that most Helios demand comes via cloud providers serving those same few frontier-model firms, rather than broad-based bulk buying, while Microsoft serves both OpenAI and Anthropic and Meta is reportedly considering its own GPU cloud business. AMD is also pushing its new Venice Epyc CPUs, offering up to 256 cores and 512 threads, to capture demand from agentic AI workloads, though it now faces stiffer CPU competition from Intel, Nvidia, Arm, Qualcomm and major cloud providers themselves.
