Trouble in Martin Place

Hey Superheroes,

Australia’s inflation picture got a little clearer this week — and the news was, for once, mostly good.

Australian CPI eased to 4.2% in the 12 months to April 2026, down from 4.6% in March and below what markets were expecting. Transport and housing costs led the moderation, and money markets quickly repriced: the probability of the RBA hiking again in June has now fallen sharply, with most economists leaning toward a pause at 4.35%. April’s labour force data added to the case, with employment falling and the unemployment rate holding at 4.5% — its highest since late 2021.

Globally, the week was defined by whiplash. The S&P 500 and Nasdaq both pushed to fresh record highs on continued AI optimism and hopes for a US-Iran de-escalation. Brent crude fell below US$95 a barrel on speculation that a framework deal between Washington and Tehran could unlock more supply, while gold retreated on a stronger US dollar. OPEC+ confirmed a production adjustment starting in June and trimmed its global demand growth forecast for 2026.

Here’s what moved this week.

Trouble in Martin Place: ASX Limited’s $20M Cost Impact

Australia’s stock exchange operator had a week it would rather forget — and Aussie investors holding its shares felt every bit of it.

💥 The announcement

ASX Limited (ASX:ASX) declined sharply by more than 13% on Tuesday 26 May, then fell a further 9.74% on Wednesday, leaving the stock at A$46.06 and down 22.56% for the week. It was the company’s worst two-day stretch in over a decade.

The trigger was a cost guidance update that caught the market off guard. ASX lifted its FY27 total expense growth forecast to 18–21%, driven by an additional A$20 million in operating costs tied to its ongoing technology modernisation program. The company also raised FY27 capital expenditure guidance to A$180–200 million and signalled FY28 capex of A$170–190 million — a sustained multi-year spending commitment that spooked investors accustomed to more predictable cost profiles.

🔍 The regulatory backstory

The costs don’t exist in a vacuum. ASIC imposed a A$150 million capital charge on ASX, to be accumulated and held in cash by 30 June 2027, as part of a broader regulatory reform package. The charge is linked directly to the botched CHESS replacement project — the clearing and settlement system that suffered one of the largest technology failures in Australian financial services industry history when it was abandoned in 2022 after years of delays and hundreds of millions in write-offs.

ASIC chair Joe Longo described the measures as being about “addressing underlying issues, and laying the foundations for a resilient, world-class market operator.” ASX, for its part, acknowledged it was rectifying what it called “historical underinvestment” and committed to a faster and more ambitious rebuild. The target is now a CHESS Release 2 primary build completed by end-2027, with a go-live in 2029.

📉 Why the market hit the sell button

The problem isn’t just the dollar figure. It’s the pattern. ASX shares have now hit 52-week lows as investors reassess what was once considered a reliable, near-monopoly earnings machine. An exchange operator’s core business — running markets — doesn’t typically require this level of remediation spending. The fact that ASX is still building toward a 2029 go-live for technology that should have been in place years ago raises questions about execution discipline that no cost guidance update can fully answer.

For retail investors, the read-through is straightforward: the market is repricing ASX as a technology turnaround story, not an infrastructure compounder. Market analysts are now debating whether the current share price adequately accounts for these multi-year technology execution risks.

Micron Cracks the Trillion-Dollar Club 💾

In the meantime, one memory chipmaker on the other side of the Pacific was doing the opposite.

🚀 The milestone

Micron Technology (NASDAQ:MU) surged 19.29% to US$895.88 on Monday, then added another 3.64% on Wednesday to close at US$928.41, pushing its market capitalisation past US$1 trillion for the first time in the company’s history. The stock is now up more than 214% year-to-date — a run that puts it among the best-performing large-cap names on Wall Street in 2026.

📊 The analyst upgrade wave

The immediate catalyst was a wave of analyst target increases. UBS lifted its price target for Micron from US$535 to US$1,625, while Barclays raised its target for the same security from US$675 to US$1,175. Both firms cited the structural shift in demand for High-Bandwidth Memory, the specialised chip architecture that sits inside Nvidia’s AI accelerators and is increasingly central to every major data centre build.

CEO Sanjay Mehrotra put it plainly: Micron has sold out its entire supply of HBM for 2026. That’s not just a demand signal — it’s a supply signal. Unlike standard DRAM, HBM is manufactured on specialised process nodes and takes months to qualify for each customer’s system. Securing a spot in a hyperscaler’s supply chain historically offers strong revenue visibility, given the months required for customer system qualification.

💡 The numbers backing the rally

Micron’s most recent quarterly result was already strong. Q1 2026 revenue came in at US$13.64 billion, up 57% year-on-year, with non-GAAP earnings per share of US$4.78 beating consensus estimates. The company reports Q3 fiscal 2026 results on 24 June — the next major test of whether the AI memory thesis is holding.

🔮 The bigger picture

As noted in last week’s Spotlight, Micron’s entire 2026 HBM production was already sold out under binding contracts, with hyperscalers signing multi-year supply deals rather than quarterly ones. The difference between then and now is that Wall Street has caught up to what the supply chain was already saying. Whether Micron can sustain a trillion-dollar valuation depends on its ability to ramp HBM production without the yield issues that have plagued complex 3D stacking processes — and to hold its position as Nvidia, AMD and the custom chip crowd keep demanding more memory bandwidth per chip generation.

With the stock up significantly year-to-date, institutional analysts are divided on how much future high-bandwidth memory growth is already priced into the valuation.
