Market values of major tech firms declined in August amid concerns over escalating artificial intelligence infrastructure costs and rising recession risks that would make the stocks particularly vulnerable during a market correction.

Last month, Alphabet Inc's lost 4.7% of its market value as a slowdown in YouTube's advertising sales fuelled concerns about its earnings. A US judge's ruling that Google had violated antitrust laws and the emergence of new competition from OpenAI, which is developing an AI-based search engine prototype, also contributed to its shares' decline.

Amazon.com Inc's market value fell 4.5%, affected by slowing online sales.

Tesla's market capitalisation fell 7.7% last month after weaker Q2 earnings and following the news that Canada planned a new 100% tariff on Chinese-made electric vehicles, Reuters reported.

The world's most valuable automaker started shipping Shanghai-made EV's to Canada last year and Ottawa's plans raised concerns about the potential profit impact of exporting from its higher-cost US production base.

Meanwhile, Nvidia's market value fell in the last week of August by 7.7% to $2.92 trillion, after it projected third-quarter gross margins below market estimates and reported revenues that only met expectations, disappointing investors who were expecting a stronger performance.

Nvidia, which commands more than 80% of the AI chip market, stands in a unique position as both the largest enabler as well as beneficiary of surging AI development.

On a positive note, US drugmaker Eli Lilly's market value surged nearly 20%, leading market gainers, driven by robust sales and the launch of a weight-loss drug that significantly reduces the risk of developing type 2 diabetes in overweight adults.

Berkshire Hathaway's market value closed above $1 trillion for the first time at the end of August, reflecting investor confidence in the conglomerate that Warren Buffett built over nearly six decades into what many consider a proxy for the US economy.

Meta's market value also climbed nearly 10% after it beat market expectations for its second-quarter revenues and forecast strong revenue growth in the July-September quarter, indicating that strong digital ad spending on its platforms could offset the costs of its AI investments.

The State Department is warning US diplomats of attempts to impersonate Secretary of State Marco Rubio and possibly other officials using technology driven by artificial intelligence, according to two senior officials and a cable sent last week to all embassies and consulates.

The warning came after the department discovered that an impostor posing as Rubio had attempted to reach out to at least three foreign ministers, a US senator and a governor, according to the July 3 cable, which was first reported by The Washington Post.

The recipients of the scam messages, which were sent by text, Signal and voice mail, were not identified in the cable, a copy of which was shared with The Associated Press.

“The State Department is aware of this incident and is currently investigating the matter,” it said. “The department takes seriously its responsibility to safeguard its information and continuously takes steps to improve the department’s cybersecurity posture to prevent future incidents.”

It declined to comment further due to “security reasons” and the ongoing investigation.

One of the officials said the hoaxes had been unsuccessful and “not very sophisticated.” Nonetheless, the second official said the department deemed it “prudent” to advise all employees and foreign governments, particularly as efforts by foreign actors to compromise information security increase.

The officials were not authorized to discuss the matter publicly and spoke on condition of anonymity.

“There is no direct cyber threat to the department from this campaign, but information shared with a third party could be exposed if targeted individuals are compromised,” the cable said.

The FBI warned in a public service announcement this past spring of a “malicious text and voice messaging campaign” in which unidentified “malicious actors” have been impersonating senior US government officials.

The scheme, according to the FBI, has relied on text messages and AI-generated voice messages that purport to come from a senior US official and that aim to dupe other government officials as well as the victim’s associates and contacts.

It is the second high-level Trump administration official to face such AI-driven impersonation.

The government was investigating after elected officials, business executives and other prominent figures received messages from someone impersonating President Donald Trump’s chief of staff, Susie Wiles. Text messages and phone calls went out from someone who seemed to have gained access to the contacts in Wiles’ personal cellphone, The Wall Street Journal reported in May.

Some of those who received calls heard a voice that sounded like Wiles, which may have been generated by artificial intelligence, according to the newspaper. The messages and calls were not coming from Wiles’ number, the report said.
