  • OpenAI partners with Broadcom to design its own AI chips

    OpenAI partners with Broadcom to design its own AI chips

    OpenAI said Monday it is working with chipmaker Broadcom to design its own artificial intelligence computer chips.

    The two California companies didn’t disclose the financial terms of the deal but said they will start deploying the new racks of customized “AI accelerators” late next year.

    It’s the latest big deal between OpenAI, maker of ChatGPT, and the companies building the chips and data centers required to power AI.

    OpenAI in recent weeks has announced partnerships with chipmakers Nvidia and AMD that will supply the AI startup with specialized chips for running its AI systems. OpenAI has also made big deals with Oracle, CoreWeave and other companies developing the data centers where those chips are housed.

    Many of the deals rely on circular financing, in which the companies are both investing in OpenAI and supplying the world’s most valuable startup with technology, fueling concerns about an AI bubble. OpenAI doesn’t yet turn a profit but says its products now have more than 800 million weekly users.

    “What’s real about this announcement is OpenAI’s intention of having its own custom chips,” said analyst Gil Luria, head of technology research at D.A. Davidson. “The rest is fantastical. OpenAI has made, at this point, approaching $1 trillion of commitments, and it’s a company that only has $15 billion of revenue.”

    OpenAI CEO Sam Altman said the work with Broadcom to develop a custom chip began about 18 months ago. Broadcom also works with other leading AI developers, including tech giants Amazon and Google.

    Altman said on a podcast announcing the deal that the computing power made possible through the Broadcom partnership will amount to 10 gigawatts, which he described as “a gigantic amount of computing infrastructure to serve the needs of the world to use advanced intelligence.”

    Broadcom shares surged more than 9% on Monday.

    Broadcom CEO Hock Tan said on the same podcast that OpenAI needs more computing capacity as it progresses toward a “better and better frontier model and towards superintelligence.”

    “If you do your own chips, you control your destiny,” he added.

  • Rio Tinto releases third quarter 2025 production results

    Our pace continues – strong production across the portfolio

    MELBOURNE, Australia–(BUSINESS WIRE)–
    Rio Tinto Chief Executive Simon Trott said: “Safety remains our number one priority. We are deeply saddened by the tragic death of Mohamed Camara at the SimFer mine site and are committed to learning across our business to prevent future incidents. This has been a time for huge reflections on safety across the group.

    “We continue to strengthen performance from our assets, setting back-to-back quarterly production records in our bauxite business and at Oyu Tolgoi – where the underground ramp-up remains on track to boost copper output by more than 50% this year.

    “We are focused on delivering a strong finish to the year from the Pilbara. Our growth projects are also progressing at pace – at Simandou, we started loading first ore at the mine for movement down the rail and to the port in October.

    “We are on track to meet production guidance for 2025, with an upwards revision to bauxite this quarter, and are well positioned to deliver compelling mid-term production growth. We will continue to deliver further shareholder value through operational excellence, simplification and discipline on performance and capital investment.”

    Executive Summary

    • New operating model and executive team: to simplify the business and unlock additional shareholder value. New structure comprises three world-class businesses: Iron Ore; Aluminium & Lithium; and Copper. Borates and Iron & Titanium have been placed under strategic review.

    • Copper equivalent (CuEq)1 production: increased 9% in Q3 YoY, driven by strong performance across all our assets.

    • Copper: Total production is on track to achieve the higher end of full year guidance, driven by the strong ramp-up at Oyu Tolgoi. Our Kennecott mine performed as expected during the quarter while major planned maintenance at the concentrator and smelter commenced successfully.

    • Iron ore: Pilbara achieved its second highest Q3 shipments since 2019, up 6% from Q2. As part of our Iron Ore replacement strategy, West Angelas Sustaining Project received all Government approvals in October.

    • Aluminium & Lithium: Full year bauxite production guidance upgraded driven by operational excellence at our bauxite business, especially at Amrun.
