The AI trade that powered global markets is showing cracks. Alphabet and the newly listed SpaceX each fell about 10% in the latest sessions as fears over soaring AI capital spending hit megacap technology, even as chipmakers rallied and bond yields climbed. It is the clearest sign yet that investors are starting to question whether AI spending has run ahead of the returns it is supposed to deliver.
The selloff is not uniform, and that is the interesting part. While the big AI spenders dropped, the chipmakers that supply them rose, pointing to a rotation in market leadership rather than a wholesale retreat from technology.
What Happened
The damage was concentrated in the megacap AI names. Alphabet sank about 10%, while Amazon, Meta, and Palantir each fell roughly 4%, dragging the Nasdaq down about 1.3%. The trigger was mounting concern over AI capital expenditure, the hundreds of billions these companies are committing to data centres and chips.
SpaceX, fresh off the largest IPO in history in June, was hit hardest in symbolic terms, falling more than 10% after it announced plans to issue significant debt to finance its AI investments. Here is how the key names moved.
| Stock | Move | Why |
|---|---|---|
| Alphabet | about -10% | AI capex concerns |
| SpaceX | about -10% | debt issue to fund AI |
| Amazon, Meta, Palantir | about -4% | AI spending fears |
| Micron, Sandisk | about +5% | chip demand rally |
Layered on top was a hawkish Fed. With the central bank signalling possible 2026 rate hikes, the US 10-year Treasury yield climbed to around 4.49% and the 2-year to 4.21%, raising the discount rate applied to the future profits that justify high tech valuations.
Why This Matters for Investors
This is a potential turning point in the AI narrative. For two years, the market rewarded AI spending almost unconditionally; now it is starting to ask whether the returns will ever match the bills. When SpaceX falls on news that it will borrow to fund AI, it signals that investors are scrutinising how this enormous build-out gets paid for, not just how big it is.
The rotation into chipmakers is the tell. Investors are not abandoning AI; they are repositioning toward the "picks and shovels" suppliers whose demand holds up regardless of which AI company ultimately wins. Micron and Sandisk rising while Alphabet falls captures that shift from the spenders to the sellers.
For investors everywhere, including India, the episode is a reminder that the AI trade is now mature enough to have two-way risk. Indian IT and AI-linked stocks, already bruised by Accenture's weak guidance, take their cue from global tech sentiment, so a US AI wobble can ripple into the Nifty IT index.
What To Watch
The first thing to watch is upcoming AI earnings and capex guidance. If the hyperscalers keep raising spending without showing matching revenue, the market's patience could thin further, deepening the rotation.
The second is bond yields. With the 10-year near 4.49%, higher yields directly pressure high-multiple tech, so the path of yields, driven by the Fed and this week's PCE inflation data, is a key swing factor.
The third is whether the rotation broadens. If money keeps moving from megacap AI into chips, and then into other sectors, it would mark a genuine change in market leadership rather than a brief wobble.
Risks To Monitor
The clearest risk is that AI capex fears snowball into a broader tech selloff. Given how much these names weigh in US indices, a sustained derating of the AI giants would drag the whole market.
A second risk is debt-funded spending. SpaceX's plan to borrow for AI highlights a trend that, if it spreads, adds financial fragility to the AI build-out should returns disappoint.
The third is the macro overlay. A hawkish Fed and rising yields are a headwind for all growth stocks, so AI names face pressure from both company-specific capex worries and the broader rate environment. This is general information, not investment advice.
The AI trade is not over, but it has entered a more demanding phase. Investors are no longer cheering every dollar of AI spending; they want to see the payoff. How the megacaps answer that question in the coming earnings season will decide whether this is a healthy rotation or the start of something deeper.
