KEY POINTS
- Wall Street's tech-heavy Nasdaq fell 4.6% last week, its fifth straight losing session, as investors dumped AI and chip stocks and OpenAI signalled it may delay its IPO.
- The fear has spread to the ASX, because local tech increasingly trades on the global AI mood, not local fundamentals.
- Four ASX names are most exposed: NextDC, Macquarie Technology, Megaport and Weebit Nano, all data-centre or chip plays that fell on Friday.
- Our take: this looks like a valuation reset, not the end of the AI story, so it's a watch list for bargain hunters, not a reason to panic.
Wall Street’s love affair with AI just hit a rough patch, and the tremor has reached the ASX. Last week, the tech-heavy Nasdaq fell 4.6%, its fifth straight losing session, as investors fled chip stocks and digested news that OpenAI may delay its blockbuster IPO.
The worry is simple: after a year of rewarding any company touching AI, the market is suddenly asking whether all that spending will pay off. That nervousness flowed straight into Australian tech, because these days the ASX’s AI names move with the global mood, not just local results. Here are the four most in the firing line.
Why the AI Sell-Off Spread to Australia
The link is sentiment. When US chip giants fall and a marquee float as OpenAI hesitates, global investors trim risk everywhere, and Australia’s AI and data-centre stocks sit squarely in that basket. The pain was visible across Asia on Friday, where South Korea’s tech-heavy KOSPI index plunged more than 8% intraday, triggering a circuit breaker. The ASX’s tech names followed. The question for investors is whether this is a healthy pause after a huge run or the start of something deeper.

The 4 ASX Tech Stocks in the Firing Line
NextDC (ASX:NXT) is the most exposed. As Australia’s largest data-centre operator, it is a direct “picks and shovels” play on the AI build-out, so any doubt about AI spending hits it first. The stock fell 4.48% on Friday to A$14.06. We still see the long-term demand story as intact, but the valuation leaves little room for disappointment.
Macquarie Technology (ASX:MAQ), another data centre and cloud operator, slid 4.1%. It offers similar AI infrastructure exposure in a smaller package. The business is solid, but like NextDC, its shares had run hard, making it vulnerable when sentiment turns.
Megaport (ASX:MP1) dropped 3.29% to A$20.26. It provides the network connections that link businesses to cloud and data centres, so its fortunes are tied to the same AI-driven demand. If the build-out keeps going, Megaport benefits, but it feels every wobble in the theme.
Weebit Nano (ASX:WBT) fell 4.09% to A$7.98 and is the purest chip play of the group, developing next-generation memory technology. That makes it the most direct local read-through to the global semiconductor sell-off. It is also pre-revenue and speculative, so it tends to swing harder than the rest in both directions.
Should Investors Be Worried?
In our view, this looks more like a valuation reset than the end of the AI story. The companies driving the global build-out are still spending heavily, and demand for data centres and chips remains strong. The real risk is that these stocks were priced for perfection after a massive run, so a pullback was always likely. For long-term investors, weakness like this can create entry points, but we would want to see the selling settle first.
For now, treat the four as a watch list, not a panic button. The AI story is intact, but price discipline matters more than ever.
