US earnings continue to provide support for the AI-led equity story. As of early August, around 75% of US companies had beaten Q2 earnings expectations, with an aggregate beat of about 8%. AI-linked companies accounted for more than 65% of earnings growth, while non-AI companies also saw an average upward earnings revision of 6% through reporting season.1
That strength sits behind a longer-running shift in market leadership. Over the five years to 31 July 2026, US shares outperformed Australian equities by around 5% a year, while the more technology-heavy Nasdaq-100 delivered roughly 7% more per year than the Australian share market.2,3
BlackRock expects the US earnings backdrop to remain constructive. Our analysis points to US equity earnings growth of around 11.6% a year over the next five years - a pace observed in only about 15% of historical five-year periods.4 That helps explain why we continue to see the US as a key access point for the AI megaforce.
The question is increasingly about the quality of that growth. BlackRock estimates hyperscaler capital expenditure has risen by more than 80% year on year to approximately US$715 billion in 2026.5 Higher spending raises depreciation, power and financing costs before the associated revenues are fully visible, increasing the hurdle for already elevated valuations.
But spending is not automatically wasteful. BlackRock Fundamental Equities analysis suggests illustrative data-centre GPU projects can reach break-even in years three to four and generate an internal rate of return near 21% where utilisation, pricing and contract assumptions hold.6 The investment case therefore depends less on the headline capex number than on whether companies can turn infrastructure into durable revenue.

AI and digital infrastructure remain powerful long-term themes, but high expectations can translate into sharp short-term swings when markets reassess earnings, valuations, interest rates or the scale of investment spending. For investors, this makes portfolio role and position size particularly important when adding concentrated technology exposure.
ITEK tracks the Nasdaq-100 Top 30 Index, giving investors targeted exposure to the largest companies in the Nasdaq-100. As of 31 July, the index had around 70% in mega-cap stocks and approximately 65% in technology.7 This creates meaningful exposure to hyperscalers alongside the semiconductor and hardware companies supplying the AI buildout.
The opportunity is not limited to software. Top holdings include Micron Technology, Advanced Micro Devices and Broadcom, providing access to memory, chips and connectivity infrastructure, while consumer names broaden exposure to the wider US economy.8
That concentrated growth bias has been rewarded recently. From the Nasdaq-100 Top 30 Index’s inception on 22 August 2024 to 25 August 2026, it returned more than 52% and outperformed the broader Nasdaq-100 Index by around 4 percentage points.9 While past performance is of course not a reliable indicator of future performance, the result illustrates how focusing on the largest Nasdaq leaders can amplify both market leadership and market risk.
We see ITEK as a minor or satellite rather than a core holding: a way for investors comfortable with higher volatility to dial up exposure to US innovation alongside a diversified global equity portfolio. It offers a single-trade alternative to selecting individual AI winners, while retaining the flexibility to increase or reduce the allocation as market views change.
With US earnings still resilient and AI investment moving from model development into chips, data centres, power and real-world adoption, we believe the growth opportunity remains compelling. The trade-off is concentration and volatility - making ITEK most relevant for investors who want a deliberate, targeted allocation to the companies at the centre of that cycle.
