AMD tops estimates on AI demand as shares whipsaw after earnings

Advanced Micro Devices reported second-quarter revenue of $11.5 billion, with a gross margin of 54% and operating income of $2.0 billion, results that according to reports exceeded Wall Street estimates. The Santa Clara-based chipmaker also forecast current-quarter revenue above analyst expectations, citing strong demand from data-centre expansions supporting artificial intelligence. The stock had surged into the 4 August announcement, reportedly up roughly 140% year-to-date, with analysts holding 42 buy ratings and zero sell ratings on the shares, according to market reports. AMD, led by chief executive Lisa Su, sells CPUs, GPUs and AI accelerators and is positioning itself as the principal challenger to Nvidia, the industry's dominant player. The reaction to the numbers was confused. Reports conflict on the share-price move: one says the stock rose nearly 8% on earnings day, while others report declines of 7% and 5.8% in extended trading, even as quarterly capital expenditures more than doubled to $808 million. The episode shows how high expectations have become for AMD's AI ambitions.

AMD beats estimates with $11.5 billion quarter and upbeat forecast

Advanced Micro Devices released its second-quarter 2026 results on 4 August. According to reports, the Santa Clara-based chipmaker posted revenue of $11.5 billion for the quarter, with a gross margin of 54% and operating income of $2.0 billion. Both the results and the company's forward guidance were reported to have exceeded Wall Street estimates.

On the same day, AMD forecast revenue for the coming quarter above analyst expectations, according to reports, citing strong demand for its chips from data-centre expansions supporting artificial intelligence technologies. The specific figure for that forecast was not disclosed in the reports.

Analyst consensus ahead of the release had pointed to strong year-on-year growth, driven by demand for AMD's data-centre GPUs and its EPYC server processors, reports said. The company, led by chief executive Lisa Su, has positioned its accelerator and server lines as its main growth engines as spending on AI infrastructure continues to build.

Shares move sharply after earnings, but reports disagree on direction

AMD's share-price reaction to its second-quarter results is unclear, with sources offering sharply different accounts. One report said the stock rose nearly 8% on the day of the earnings release. Others reported declines: a 7% fall after the report, and a separate 5.8% drop in extended trading. The actual net movement cannot be determined from the available reporting.

The conflicting accounts sit alongside one detail that appears in the coverage of the decline: quarterly capital expenditures more than doubled to $808 million, according to reports. That jump in spending was cited in connection with the post-earnings fall, though the sources do not explain why shares would drop after results and guidance that beat Wall Street estimates. Whether investors were unsettled by the scale of AMD's spending, or whether the stock in fact rose, remains unresolved.

A 140% rally and wall-to-wall buy ratings set high expectations

Expectations were already elevated before AMD reported. According to reports, the stock had more than doubled during 2026 and was up roughly 140% year-to-date heading into the release, having risen further in the weeks immediately before the announcement.

Wall Street was almost uniformly positive. Analysts held 42 buy ratings and zero sell ratings on the shares ahead of the report, according to market data cited in coverage, and the company received analyst upgrades in the period before the release.

Consensus forecasts pointed to strong year-on-year growth, driven by demand for AMD's data-centre GPUs and EPYC server CPUs, reports said. That optimism reflected the company's expanding role in supplying chips for artificial intelligence infrastructure, a market where it competes with industry leader Nvidia. The setup left little room for disappointment when results arrived on 4 August.

Anthropic deal and MI455X chip anchor AMD's challenge to Nvidia

Under chief executive Lisa Su, AMD has pressed its challenge to Nvidia, described by analysts as the industry leader in AI chips. According to reports, the Santa Clara-based company announced a partnership with Anthropic in the month before its earnings release, under which the AI firm would deploy AMD GPUs. That deal followed earlier agreements with Meta and OpenAI, though the dates of those arrangements were not disclosed.

AMD has also presented the Instinct MI455X, a redesigned AI accelerator built for its Helios servers, which the company says can perform 40 quadrillion operations per second. The timing of that presentation was not given. Together, the partnerships and new hardware signal AMD's effort to capture a larger share of the data-centre spending driving the AI buildout.
