Apple added nearly $600 billion in market capitalisation in under a month, while Oracle shed almost half its value from a June peak and SpaceX shares tumbled toward their IPO price, marking a stark divergence in how investors are pricing exposure to artificial intelligence infrastructure. The rotation has redrawn the upper ranks of global wealth: Oracle chairman Larry Ellison fell from the world’s second-richest person to eighth, while Elon Musk’s fortune briefly dipped below $900 billion as SpaceX slid 38% from its all-time high.

Viewed from Wall Street, the mechanism is a growing scepticism about the returns on massive AI capital expenditure. Apple’s decision not to join the data-centre construction race is now framed as a strategic advantage, insulating it from the cost overruns and margin pressure plaguing peers. By contrast, Oracle’s plan to spend up to $95 billion this fiscal year drew a credit-rating downgrade from S&P Global, which warned the outlay could weaken its financial position. SpaceX, despite its rocket and satellite operations, is being reassessed after its AI division posted a $6.4 billion loss on just $3.2 billion in revenue last year, tempering the euphoria that briefly valued the company above $2 trillion.

Analysts in London and New York note that the repricing extends beyond single names. The Philadelphia Semiconductor Index has surged 83% year-to-date, yet chipmakers and cloud giants face mounting questions about the durability of AI-driven demand. Amazon, with its profitable AWS cloud division generating $1.3 trillion in annual revenue, is held up as a counterweight to SpaceX’s high-risk profile, though its own satellite internet venture remains nascent. In Moscow, market observers highlight Apple’s parallel moves to protect margins: sharp price increases on Macs and iPads, and negotiations with blacklisted Chinese chipmakers for cheaper memory, alongside expectations of a foldable iPhone launch in September that could drive a refresh cycle.

Apple’s fiscal 2026 revenue is forecast to grow 15%, its fastest pace in five years, while Oracle must demonstrate that its AI infrastructure bets can generate backlog orders that justify the spending. SpaceX faces the more immediate test of stabilising its share price after a debut that one analyst likened to a meme stock, with retail investors who bought in the first days sitting on losses. The next factual milestones are Apple’s expected September product event and Oracle’s quarterly earnings, which will offer concrete data on whether the market’s bifurcated judgment holds.
