Apple and Microsoft soar past four trillion valuation as AI fever sweeps markets

On a landmark day for global markets, Apple and Microsoft have both surpassed the four trillion dollar valuation threshold, fuelling escalating debate about whether Wall Street is entering bubble territory. The surge comes as fresh AI enthusiasm propels technology stocks to new highs, with both Apple and Microsoft shares hitting record levels on Tuesday.

This year alone, Microsoft’s shares have leapt by 28 percent, adding around 900 billion dollars to its market capitalisation. Apple, not to be outdone, has risen by 15 percent, lifting its own value by 459 billion dollars. These performances have secured their positions among the most valuable companies on the planet, even after starting the year at colossal market caps.

Analysts acknowledge the extraordinary heights these firms have reached, with Kristofer Barrett of Carmignac noting that frothy areas are forming across the market. Yet, he underlined the lasting ubiquity of their products across work and leisure for consumers. Barrett added that Microsoft appears more deserving of its valuation, given its superior growth rate and stronger innovation pipeline, whereas Apple, despite robust profits, faces ongoing debates over its AI strategy.

Microsoft shares soared by up to 4.2 percent following the announcement of a landmark agreement with OpenAI. The deal, which could see OpenAI become a publicly traded entity valued at 500 billion dollars, will allow Microsoft to take a 135 billion dollar stake, equating to 27 percent ownership. The move places Microsoft at the heart of the artificial intelligence revolution, although some market watchers are voicing caution about the high price tag and the need for OpenAI to maintain its exponential growth trajectory.

Apple shares also edged higher, reaching a record 269.87 dollars and making it only the third company ever to breach the four trillion dollar mark, following Microsoft and semiconductor powerhouse Nvidia. Robust demand for the latest iPhone models has assuaged doubts over Apple’s AI progress, with shares climbing 13 percent since their launch in September. Chris Zaccarelli of Northlight Asset Management highlighted the iPhone’s role as Apple’s profit engine, driving new customers into its lucrative ecosystem.

The AI gold rush has sent the US stock market to a series of all-time highs, with the S and P 500 closing at record levels for the thirty fourth time this year. Substantial deals continue to flow, not least with Nvidia’s billion dollar investment into Nokia and PayPal’s rally on news users will soon be able to transact via ChatGPT. Despite the frothy atmosphere, experts such as Chris Beauchamp of IG draw contrasts with the late 1990s technology bubble, pointing to the sizeable cash flows and profits generated by today’s leaders. Last year alone, Microsoft and Apple earned net incomes exceeding 95 billion and 100 billion dollars, respectively.

Mike Fox of Royal London Asset Management urged restraint in declaring an imminent bubble, observing that the valuations of Apple and Microsoft are not far above other high-quality firms outside the AI sphere. The long-term test will be the ability of these giants to monetise AI innovation and justify their unprecedented valuations.
