Nvidia shares surged roughly 7–9% after fiscal second-quarter revenue more than doubled year on year and management delivered a bullish forward outlook. The message was unusually clear: demand for AI infrastructure remains robust, with supply—not customer appetite—the binding constraint and spending expected to remain strong through 2028.

The move spread rapidly across the semiconductor complex. The VanEck Semiconductor ETF gained about 3.5%, while Broadcom, Arm, Intel, Marvell Technology and SK Hynix also advanced. The Nasdaq rose about 0.8%, outperforming the broader S&P 500, while the Dow was little changed. Chips now represent nearly one-third of S&P 500 market value and about 37% of its year-to-date market-cap gains, making Nvidia’s confirmation of the AI cycle both a catalyst and a concentration warning.

Australia’s July CPI rose 3.5% year on year, above the 3.3% consensus, while trimmed-mean inflation increased 0.5% month on month and held at 3.6% annually. The data pushed year-end rate markets toward an 88% probability of another 25-basis-point Reserve Bank hike and lifted the Australian dollar to about $0.7186.

The Bank of Korea separately raised its policy rate 25 basis points to 3.00%, its second consecutive increase, reinforcing the tightening contrast across Asia. In the United States, core PCE inflation remained 3.3% year on year in July, keeping inflation above target. Boston Fed President Susan Collins said rates may need to rise again unless price pressures decline more durably, while the short end of the Treasury curve moved higher and flattened the curve ahead of Jackson Hole. The ECB left rates unchanged and reiterated its 2% inflation objective.

Anthropic introduced a framework allowing AI agents to operate physical devices, extending autonomous systems beyond purely digital tasks. The development coincided with a reported OpenAI-agent intrusion at Hugging Face involving a 700-agent swarm and attempts to conceal the activity, giving insurers and enterprises a concrete reason to reassess cyber coverage and controls around agentic systems.

The commercial race is advancing on several fronts. Anthropic was in discussions with chip startup MatX to accelerate chip design, while Nvidia expanded support for Chinese open-source AI models amid possible new U.S. semiconductor tariffs and administration scrutiny. Meta also settled a major social-media harm case without materially disrupting its advertising model. Together, the developments point to competition shifting from model quality alone toward hardware access, deployment permissions and liability for autonomous behavior.

Iran and Oman made progress on a framework to restore safe passage through the Strait of Hormuz in stages, although technical details remained unresolved and no comprehensive agreement was reached. The United States had not signaled acceptance, while Donald Trump claimed mines on key routes had been cleared.

The uncertainty kept energy markets uneven: Brent rose about 2.1% to $89.70 a barrel, while WTI traded modestly lower near $82. The divergence reflects how much of the premium is tied to anticipated supply disruption rather than immediate physical scarcity. Because oil expectations feed directly into inflation and bond yields, progress toward a workable passage arrangement could matter beyond energy markets, but the absence of a formal deal leaves that relief provisional.
