Microsoft launches Maia 300 AI chip as Nvidia stays strong

Microsoft announced its third-generation AI chip, Maia 300, and plans to ramp up deployment starting in 2027. The chip will be the main inference system for Microsoft products and services. Microsoft expects Maia 300 to generate 40% more tokens per megawatt than leading alternatives. Despite this, Nvidia remains strong, with revenue growing 106% year over year and guidance pointing to about 89% growth.

Microsoft stock hits record high after AI chip announcement

Microsoft's share price closed at a record $543.45, capping a four-month rally. The company announced the third generation of its custom AI chip, Maia 300, and said it will deploy the chips widely next year. Microsoft expects Maia 300 to deliver 40% more tokens per megawatt than leading graphics processing units. The company also reported over 30 million paid Copilot users.

Microsoft's Maia chips grow but Nvidia still leads the market

Microsoft now has three generations of its own AI chips and plans to make Maia the primary inference system for its products. Nvidia's revenue reached $96.2 billion in one recent quarter, up 106% year over year. Nvidia's sales to hyperscale customers more than doubled, while revenue from other data center customers climbed 138% to $40.3 billion. Nvidia's fiscal Q3 guidance points to growth of about 89%.

Intel could benefit from Elon Musk's Terafab chip project

Elon Musk's Tesla and SpaceX are building a semiconductor facility called Terafab in Grimes County, Texas. Intel is involved in the project and could become a major beneficiary. Terafab aims to produce chips for Tesla's autonomous vehicles, Optimus robots, and SpaceX's space-based data centers. Intel Foundry generated $5.8 billion in revenue during the second quarter but reported an operating loss of about $2.1 billion.

Tesla and SpaceX build Terafab with Intel involved

Tesla and SpaceX committed initial investments of $16.8 billion for the first phase of Terafab, a proposed chip manufacturing facility in Texas. Intel's participation was confirmed in April, positioning its manufacturing expertise alongside Musk's plans. Intel is developing its 18A and 14A manufacturing processes to compete with Taiwan Semiconductor. Intel Foundry reported $5.8 billion in revenue and an operating loss of approximately $2.1 billion in the second quarter.

Japan's Nikkei falls as AI stocks and geopolitical tensions drag markets down

Japan's Nikkei 225 index dropped 2.64% to 67,206.79, marking its steepest fall since March 2020.

Geopolitical tensions, including the conflict in Ukraine and potential US-China trade issues, also weighed on investor sentiment. The broader Topix index also fell 2.55% to its lowest level since October 2020.

AI tools help CFOs prepare for earnings calls

Expensify Inc. created an AI bot called the Ryan Bot to help CFO Ryan Schaffer prepare remarks for earnings calls. The bot was trained on Schaffer's past public comments to match his speaking style.
