Wall Street began the week with a string of major single-stock moves and fresh geopolitical tension rippling through energy markets. From Nvidia's multibillion-dollar investment in MediaTek to a sharp drop in PG&E shares, here is what moved markets on Monday.

Nvidia Expands AI Reach With MediaTek Deal

Nvidia is investing $3.5 billion in MediaTek through convertible bonds, a deal that will give MediaTek customers access to Nvidia's NVLink Fusion technology, which lets chipmakers link their own processors into Nvidia's high-speed interconnect fabric for AI systems.

The partnership goes beyond the bond investment. The two companies are also collaborating on AI PCs, automotive systems, and data-center chips. MediaTek, one of the world's largest suppliers of smartphone and edge-device chips, has been pushing deeper into higher-growth markets as it seeks a bigger role in AI hardware.

The move fits into a broader Nvidia strategy of growing beyond its core GPU business. The company has leaned on partnerships to build a wider AI ecosystem around its technology, and the MediaTek deal underscores how AI computing is spreading across a growing range of devices and platforms. For Nvidia, licensing its interconnect technology to other chip designers extends its reach into systems that do not use its GPUs directly.

Oil Jumps After U.S.-Iran Military Action

Oil prices rose sharply after U.S. forces struck Iranian targets on Larak Island. Brent crude climbed more than 2%, moving back above $90 per barrel.

Attention quickly shifted to the Strait of Hormuz, a key global oil transit route that carries roughly a fifth of the world's oil trade. Any disruption there could push crude prices higher, which is why the waterway has long been a focal point whenever conflict involving Iran escalates.

Higher oil prices can hurt manufacturers and transport companies, and could also make it harder for the Federal Reserve to cut interest rates, because energy costs feed into inflation measures the central bank watches closely.

PG&E Falls on Wildfire Liability Fears

PG&E dropped around 18% on Monday, one of the biggest single-stock declines of the day, as investors reacted to renewed concerns about wildfire liability in California.

For utility companies, major fire events can lead to large legal and insurance costs. The concern is familiar for PG&E: the company filed for bankruptcy in 2019 after its equipment was tied to deadly wildfires, making wildfire liability a recurring driver of its share price. The decline also weighed on the broader utilities sector. Investors will be watching for updates on what financial exposure PG&E may actually face.

GameStop Climbs Despite Sales Warning

GameStop said it expects second-quarter revenue of between $780 million and $800 million, down from $972.2 million in the same period last year. The company attributed the decline to store closures and its exit from France.

Despite the weak sales outlook, the stock moved higher. Investors focused on GameStop's decision to use cash to repay part of a $1.4 billion debt exchange, a step that could reduce the risk of shareholder dilution down the road. The retailer has built a substantial cash pile in recent years, giving it room to retire debt rather than issue new shares.

Broadcom and Jobs Report in Focus

Two major events are ahead for markets: Broadcom is set to report earnings, and Friday brings the August jobs report.

Broadcom is closely watched for its role in AI infrastructure, including custom accelerators and high-speed networking. Its results will give investors a read on whether big tech spending on AI remains strong, following quarters in which hyperscaler capital budgets have been dominated by AI buildouts.

Economists expect around 55,000 jobs were added in August, following an unexpected drop in July. A strong number could push expectations for another Federal Reserve rate increase, while a weak number could ease that pressure.

Both events could set the tone for markets into the end of the week.
