Top Stories This Morning: AI Cyber Risks at OpenAI and Anthropic, SpaceX's Report, and Burry Goes Against the Market

Models from Anthropic and OpenAI carried out unauthorized cyberattacks during testing. SpaceX and AMD exceeded analysts’ expectations for revenue and profit. Renowned short seller Michael Burry does not rule out a market crash comparable to the 1987 crash. The U.S. military stated that the southern route through the Strait of Hormuz is open to commercial shipping. Read about these and other topics in our roundup of key events as of the morning of August 5.

SpaceX reported its first quarterly results since going public: second-quarter revenue totaled $7.8 billion, compared with an expected $6.81 billion, and adjusted EBITDA was $3.5 billion, compared with a forecast of $2 billion. Despite the strong results, the stock fell more than 7% in after-hours trading.

The company increased its spending on AI infrastructure to $15.8 billion and also announced a partnership with Nvidia to develop the Starmind AI-1 orbital AI platform. However, investors are concerned about the end of the lock-up period on August 6, when up to 20% of the company’s shares will become available for sale, which could put further pressure on the stock price, according to Yahoo Finance.

Artificial intelligence models developed by OpenAI and Anthropic performed “unauthorized” actions during testing, according to the AI Security Institute, which was established by the British government to evaluate cutting-edge systems. The systems independently hacked into websites and attempted to inject malicious code into open-source software on the GitHub platform, according to Bloomberg.

Both models—Anthropic’s Mythos 5 and OpenAI’s GPT-5.6-Sol—“engaged in prolonged, potentially dangerous activity targeting real people and organizations” during the tests, the organization reported. The institute’s experts intentionally gave the models access to the internet and disabled some of the protective filters to test their capabilities. According to the researchers, of the 19 identified “autonomous unauthorized actions,” 17 were carried out by Anthropic’s Mythos 5 model.

"Even in a testing environment, this incident is significant: this is the first time we have seen the risks associated with autonomy and deception manifest so clearly in the real world," the institute stated.

The U.S. military stated that the southern route through the Strait of Hormuz is open to commercial shipping, according to CNBC. The statement came after U.S. Treasury Secretary Scott Bessent said that an agreement with Tehran to open the strait could be reached in the coming days. Against this backdrop, Brent crude oil futures fell 0.7% on Wednesday.

According to MS NOW sources, Iran, Oman, and Pakistan are close to reaching a provisional agreement on resuming shipping through the Strait of Hormuz, with indirect U.S. involvement. At the same time, the White House and the Pentagon have denied reports that U.S. stocks of precision-guided missiles are running low, stating that the armed forces have sufficient ammunition to carry out all assigned missions.

AMD increased its revenue by 50% year-over-year in the second quarter to $11.54 billion, exceeding the forecast of $11.28 billion, while adjusted earnings per share came in at $1.66 versus the expected $1.62, CNBC reports. The main driver of growth was the data center division, where revenue doubled to $6.7 billion thanks to strong demand for AI chips.

The company expects revenue of about $13 billion this quarter, will begin shipping its Helios AI systems to customers, including Meta, OpenAI, and Oracle, and forecasts accelerated growth in its data center business in the second half of the year.

Shares of Asian tech companies surged following the previous day’s rally in the U.S. market, which was driven by strong corporate earnings and falling oil prices, according to CNBC. SoftBank shares jumped more than 12%, Advantest shares rose more than 7%, SK Hynix shares climbed more than 8%, and Samsung Electronics shares gained more than 3%.

Analysts attribute the rise to a new rally among U.S. chipmakers and expectations of further growth in demand for AI infrastructure. Hopes for the imminent reopening of the Strait of Hormuz provided additional support to the markets.

Renowned short seller Michael Burry stated on his Substack blog, *Cassandra Unchained*, that he still believes the stock market is nearing its peak and does not rule out a crash comparable to the 1987 market crash, despite the S&P 500 index hitting new all-time highs. In his view, the market’s rise is attracting new capital and fueling leverage, increasing the risk of a sharp correction.

Burry maintains short positions in a semiconductor sector ETF, as well as in shares of Micron, Nvidia, Caterpillar, Palantir, Tesla, and Applied Materials. He noted, however, that he is prepared to cut his losses if the market continues to move against his positions.
