Amid warnings from major AI giants to slow their development pace, the UK King will convene an AI summit.

According to filings with the U.S. Federal Election Commission (FEC), Elon Musk injected $77 million into the super political action committee (super PAC) America PAC he supports in the first two weeks of October, bringing his total donations for this election cycle to over $445 million, making him one of the largest individual donors to a super PAC in U.S. political history. America PAC spent $43 million during the same period, ending with a cash balance of $46.5 million. Since August, the organization has allocated $43.2 million to voter outreach and get-out-the-vote efforts, and spent $8.8 million on digital media and text messaging services. The funds are primarily directed to key congressional races in states including Texas, Ohio, and Michigan, with spending on Texas Senate races being particularly prominent. Additionally, Musk donated $158 million to the Senate Leadership Fund, which supports Republican Senate candidates, in September. As the U.S. midterm elections approach, both major parties are ramping up financial contributions; as of the end of the third quarter, Trump, the Republican Party, and congressional super PACs backing Republican candidates have raised a total of $2.1 billion, exceeding the $1.3 billion raised by Democratic-aligned organizations.

Beating AI Insight Flash: OpenAI fired three security researchers at the end of September for violating sensitive information management rules. The Wall Street Journal disclosed more details on October 22: the company suspected the three of leaking model architecture secrets to external security expert Ryan Greenblatt, and demanded they unlock their personal phones. Investigators found that some of the chat logs between the researchers and Greenblatt on Signal had auto-delete enabled. A week later, the three were summoned to a meeting and fired simultaneously. Greenblatt had participated in OpenAI’s external security investigations, and one of the fired researchers was responsible for collaborating with external security agencies. All three denied leaking secrets, stating the dismissal was likely related to their advocacy for AI safety oversight. One of them also claimed he was fired for accidentally opening an executive email he had access to. OpenAI denied retaliation, emphasizing the dismissal stemmed from violations uncovered in internal investigations, not employees raising safety concerns. However, the company did not release full details of the violations, and the three researchers said they never received a written explanation.

According to a South Korean media report on October 23, Samsung Electronics has launched follow-up equipment investment at its No. 1 wafer fab in Taylor, Texas, completing the final pre-mass production phase of setup. This facility is Samsung’s first wafer foundry mass production line in the U.S., targeting 20,000 wafers per month of 2-nanometer capacity by the second half of next year. Samsung has recently ordered equipment, initially to meet a monthly capacity of around 6,000 wafers, with the equipment arriving gradually. The No. 1 fab broke ground in 2022, with Samsung’s total investment reaching approximately $37 billion. It is scheduled to begin operations by the end of 2026 and start mass production of EUV-based 2-nanometer chips from 2027. Samsung’s 2-nanometer yield has risen from around 60% earlier this year to roughly 80%, meeting mass production requirements. In terms of orders, the fab has secured full 2-nanometer orders before launch, with clients including Tesla’s AI5 and AI6 chips, Broadcom’s communication chips, and Arm’s smart device chips. Samsung and Tesla signed a $16.5 billion long-term supply contract in July 2025, valid through the end of 2033. Expansion plans do not stop here. Samsung plans to break ground on Taylor’s No. 2 fab in early November, which will be 1.5 times the size of the No. 1 facility, targeting mass production of 2-nanometer chips by 2030. Samsung’s total investment in central Texas exceeds $37 billion, and the U.S. CHIPS and Science Act has approved up to $4.745 billion in direct subsidies. The competitive landscape remains to be tested. TrendForce data shows TSMC held a 72.5% global wafer foundry revenue share in the second quarter of this year, while Samsung accounted for 5.9%. The Taylor fab’s capacity ramp and yield stability will determine whether Samsung can convert its order momentum into a market share recovery.

Beating AI Express News: The Arc browser is truly coming to an end. The Browser Company announced it will fully discontinue support for the macOS and Windows versions of Arc on December 22, 2026, and has already closed new user registrations. Starting November 23, the mobile version’s AI features, login functionality, and tab sync will be phased out gradually. The team will now focus entirely on its AI browser Dia. Arc launched in 2022, initially available exclusively to Mac users via invitation. It opened to all users in 2023, and expanded to Windows and mobile platforms in 2024. It reimagined the traditional browser with innovations including a vertical tab bar, dedicated workspaces, automatic tab organization, split-screen browsing, and even direct webpage customization. These designs made it a favorite among tech enthusiasts globally. China’s tech community once closely studied its design and development model, regarding it as a popular alternative to Chrome. The company previously revealed that Arc had over 1 million weekly active users, but its popularity did not translate into broad adoption. Founder Josh Miller acknowledged in 2025 that Arc was too complex for average users, with a steep learning curve, and only 5.52% of daily active users regularly used multiple workspaces. That same year, the team halted new feature development to pivot to Dia. In October 2025, its parent company was acquired by Atlassian for roughly $610 million. Now, the team has decided to end all maintenance for Arc, reasoning that browser security in the AI era requires ongoing investment, so engineering and security resources must be concentrated on Dia. Arc never became the next-generation Chrome, but it opened countless people’s eyes to what browser design could be. The creative concepts it introduced will live on in other browsers. Unfortunately, Arc itself will not get to see that future.
