Apple has joined an ultra-exclusive club once again. The company’s stock climbed past the $4 trillion market cap mark, becoming only the third firm to do so—alongside Nvidia and Microsoft.
The milestone caps off a strong quarter fueled by surging iPhone 17 sales, even as new US tariffs threatened to shake up the global supply chain. Apple’s shares reportedly reached record highs of $269.2, representing nearly a 13% increase since its launch of the iPhone 17 lineup.

 OpenAI has announced its first developer conference in India, called DevDay Exchange, scheduled for November 4, 2025, in Bengaluru. The event will focus on connecting with Indian developers, educators, and enterprises, while also introducing new initiatives tailored for the local market. The decision to host this event in India highlights the country’s growing importance in OpenAI’s global expansion and its rapidly developing AI ecosystem. To celebrate this milestone, OpenAI is offering a free one-year subscription to ChatGPT Go. |  China has achieved a significant milestone in semiconductor technology that could alter the global landscape in chip manufacturing. A team led by Professor Hailin Peng from Peking University, working with domestic collaborators, has developed a method to reduce defects in chip lithography dramatically. The discovery could help China reduce reliance on foreign photoresist materials and improve chip yields at advanced nodes. |
 Oppo has recently unveiled the Find X9 smartphone for the global market, a couple of weeks after its launch in China. The Find X9 comes with a 6.59-inch AMOLED display offering a 2760×1256 resolution, 120Hz refresh rate, and 3600 nits of peak brightness. It also features 3840Hz PWM dimming for reduced flicker. The design includes a flat aluminum frame and matte glass back, available in Titanium Grey, Space Black, and Velvet Red. |  Xiaomi’s slick new Hyper Island featur, the pill-shaped live activity hub introduced with HyperOS 3, is no longer exclusive to premium devices. A recent software tweak quietly unlocked it for Redmi and Poco phones as well, though there’s a small trade-off for budget users. According to insider PaperKing13, all handsets from Xiaomi, Redmi, and Poco that are eligible for HyperOS 3 will get the Dynamic Island-style notification feature. |
