Instagram head Adam Mosseri testified before U.S. District Judge Yvonne Gonzalez Rogers in Oakland, California, as 29 U.S. states filed a lawsuit alleging that Meta designed its platforms to addict children and improperly collected data from minors, with potential civil penalties approaching $200 billion. The trial, which began on August 25, 2026, centers on claims that Meta violated federal law by gathering personal information from children under 13 and using design choices to increase teen engagement. Mosseri said the “Take a Break” feature, which prompts users to pause after a set period, was used by a low‑single‑digit percentage of teenagers before it became the default in September 2024. He noted that early testing indicated more than 90 % of teens who activated the feature continued to use it, but that most teenagers did not want the feature. Mosseri denied any knowledge of an internal policy to withhold safety data and said he wanted high‑quality, expert‑backed information to be public. Instagram product design director Francesco Fogu testified that a 2023 presentation showed teenage users were exposed to 1.5 times more bullying, suicide‑related, hate, nudity and violent content than adult users; he later said the figure appeared on a different slide. The states allege that Meta’s design contributed to anxiety, depression and suicide among minors, while Meta contends its research shows no clear link between social media use and mental‑health outcomes. The case may result in liability findings, civil penalties and required changes to Facebook and Instagram platforms. The judge will decide on liability and any penalties, and the outcome could set a precedent for how social media companies address child safety and data privacy.

Nvidia Corp. will report third‑quarter earnings on Wednesday, a test of whether its new Vera Rubin processors can sustain revenue growth as investors examine the company's large AI financing commitments. Analysts project sales to rise 82.8% year‑over‑year to $104.20 billion, the fastest growth rate in seven quarters, according to LSEG data.

The chipmaker has been a major beneficiary of the AI infrastructure build‑out, with data‑center spending projected to exceed $730 billion this year. Nvidia’s shares have gained 11.8% year to date but have lagged rivals such as Apple, and the company briefly fell behind Apple in market‑cap rankings last month.

The rollout of Rubin chips, expected to begin this autumn, is critical as Nvidia faces custom AI processors from Intel and AMD as well as in‑house chips from other technology firms. Morgan Stanley estimates Rubin could contribute nearly $9 billion in sales for the quarter ending October, while analysts expect gross margin to remain around 75% for the second and third quarters.

Scrutiny of AI spending has intensified after Nvidia helped arrange $500 billion in financing from six major U.S. banks for AI infrastructure projects and agreed to guarantee up to $105 billion for OpenAI’s 20‑year lease of a data‑center in Ohio. The guarantees have prompted questions about the sustainability of AI demand and whether they create circular financing. Brian Mulberry, chief market strategist at Zacks Investment Management, which holds Nvidia shares, said the risk is total AI exposure without diversification and that continued growth in AI tool adoption is essential for success. CEO Jensen Huang said the financing uses Nvidia’s cash reserves to support customers building data centers, power supplies and facilities that will house its chips for decades, and that the Ohio arrangement does not constitute circular financing because OpenAI will pay the lease.

The report and the speed of Rubin adoption will indicate whether Nvidia can maintain its growth trajectory amid growing competition and heightened scrutiny of its financing practices.

The Wall Street Journal said it did not breach its standards after publishing an op-ed by billionaire investor Stanley Druckenmiller that was written with assistance from artificial intelligence.

Paul Gigot, the Journal’s editorial page editor, said AI is a common tool for writing, research, grammar and editing, and that the piece reflects Druckenmiller’s own argument. He noted the paper has had a long‑standing relationship with Druckenmiller and that no one doubts the op‑ed is his genuine opinion.

The op‑ed, published on Monday, criticized Treasury Secretary Scott Bessent’s interventions in the U.S. bond market. Shortly after publication, social media users and AI detection tools questioned whether the column was fully authored by Druckenmiller. NOTUS asked Druckenmiller about AI use, and he replied that he used AI to write the column.

Druckenmiller said he now uses AI for writing as he uses a calculator for mathematics and said he was not embarrassed by the method. The Journal did not disclose the AI assistance to readers when the piece appeared, nor did it add a later note after Druckenmiller confirmed the technology’s role.

The newsroom follows editorial standards separate from its news reporting. A company spokeswoman said the newsroom uses generative AI for investigations, summarizing articles and translation, and that AI‑generated content is reviewed by a journalist before publication. News Corp, the parent company, has a content partnership with OpenAI and uses Google Vertex AI, and it states it adheres to values of accuracy, accountability, originality, quality, transparency and respect for intellectual property.

Tech investor Jason Calacanis wrote on X that failing to disclose AI‑generated writing in the first sentence is unforgivable, arguing that readers should know if a piece was produced by a chatbot. Bloomberg podcaster Joe Weisenthal responded that the quality of writing matters more than whether it was AI‑generated, noting that high‑profile figures have long published op‑eds written by others without controversy.

Alex Mahadevan, who runs Poynter Institute’s MediaWise project, said the Journal is correct that AI is now part of everyday life, but using it to produce an entire opinion piece without clear disclosure conflicts with current AI ethics norms. He said the outlet should have disclosed the AI use because audiences want to know whether they are reading human writing or content generated by a chatbot, and he criticized the writing quality as insufficient.

The controversy underscores a broader debate about transparency and authorship in AI‑assisted journalism.

On August 24, Treasury Secretary Scott Bessent said the Treasury will accelerate purchases of Treasury bonds to raise their price and push yields lower. Treasury yields had been climbing to levels not seen in two decades, reflecting concerns about fiscal policy and interest rate outlook. The 10‑year Treasury yield fell briefly after the announcement but returned to its prior level by Friday afternoon, while the 30‑year yield remained near its highest point in 20 years. Bessent’s plan calls for large‑scale buying of bonds in the open market, a move intended to support prices and reduce the cost of borrowing for the government. Market participants said the intervention was insufficient to alter the upward trend in yields, and some analysts noted that broader fiscal expectations continue to dominate trading activity. Whether the Treasury’s bond‑buying strategy can sustain lower yields remains unclear as the administration continues to navigate fiscal policy discussions.
