According to Reuters, the U.S. Department of Justice (DOJ) has launched an investigation into Nvidia’s acquisition of open-source AI model platform Hugging Face, focusing on its impact on AI competition and Nvidia’s business practices. Citing two people familiar with the matter, Reuters reported that DOJ officials have questioned whether the roughly $129 billion deal would give Nvidia control over a critical distribution hub in the AI sector, and whether Nvidia could use Hugging Face to harm competitors or leverage it as a bargaining chip. Officials also raised questions about Hugging Face’s rivals. The sources said the DOJ’s recent broad investigation covers Nvidia’s acquisitions and investments, sales practices, and whether the company pressures customers. The probe began under the Biden administration and has continued into the Trump administration; Reuters noted there is no indication that Trump is involved. Separately, the DOJ is also examining whether, after obtaining technology licenses from chip startup Groq and hiring its core engineers, Nvidia allocated more AI chips to customers that purchased both networking equipment and Groq processors. The SchedMD acquisition announced in December 2025 and the Run:ai acquisition have also come under scrutiny. Reuters emphasized that an investigation does not constitute evidence of wrongdoing and does not necessarily lead to litigation. When Nvidia announced its Hugging Face acquisition last month, it stated that the platform would continue to support partnerships with all types of semiconductor, cloud, and AI vendors, and remain open to the entire AI ecosystem. The deal is expected to close in the first half of next year.

South Korea-listed Samsung Electronics released its official third-quarter 2026 financial results today. Figures show the company recorded 195.3 trillion won in revenue for the quarter, slightly higher than the preliminary figures previously announced; operating profit for Q3 stood at 107.4 trillion won. However, net profit for the quarter came in at 75.2 trillion won, missing the market consensus estimate of 83.6 trillion won. Following the earnings release, Samsung Electronics’ stock price dipped briefly before recovering slightly, and is now up 0.2%. By business segment, the semiconductor division remains the company’s core performance driver. The chip division posted an operating profit of 106.5 trillion won in Q3, accounting for nearly all of the company’s total profit. Among its segments, foundry business revenue saw sharp growth, with the company forecasting double-digit revenue growth for the segment in Q4. In addition, the display business maintained steady profitability, logging an operating profit of 1.1 trillion won. In contrast, the mobile division underperformed, posting an operating loss of 600 billion won in Q3. On the shareholder return front, Samsung Electronics announced a dividend of 4,601 won per share for Q3, with total dividend payouts reaching 30 trillion won. Looking ahead, Samsung’s management is optimistic about the semiconductor market, forecasting continued expansion in demand for memory chips in Q4, and warning that chip supply shortages will worsen next year.

Insight Beating AI Flash News: Google Unveils Gemini 4 Carbon. It has been only half a month since its previous flagship model Argon was made available to the public. Third-party evaluation firm Artificial Analysis’s latest Intelligence Index v5.0 shows Carbon topped the ranking with 59 points, outperforming Claude Opus 5.5 (58 points) and GPT-6 Astra (57 points), and scoring 9 points higher than Argon. The upgrade is particularly prominent in cybersecurity: Carbon can not only detect software vulnerabilities, but also verify whether they are exploitable and generate fix patches. It ranked first in all three corresponding tests, with scores of 88.2%, 54.8% and 71.0% respectively. However, Carbon is not fully leading: in Artificial Analysis’s programming agent ranking, it still lags behind Opus 5.5. Google has not yet made Carbon available to the public. This week, it will first be trialed by a small number of cybersecurity defense teams before gradually expanding access. The API’s promotional price is $2 per million input tokens and $10 per million output tokens, the same as Argon. Prices will double after the promotion ends.

According to Yu Jin Monitoring, HyperLabs, the development team of Hyperliquid, filed a request to redeem 179,706 HYPE tokens from staking roughly 10 hours ago, worth approximately $14.49 million. Under staking withdrawal rules, this batch of HYPE is expected to be credited on the evening of November 4, around 7 days from now. Yu Jin pointed out that the redemption path follows the same process as the team’s prior token unlocks: after exiting staking, HYPE will first be allocated to team members, then traded over-the-counter (OTC) via market maker/institutional trading platform Flowdesk. The associated staking address is 0x43e...251.
