Artificial‑intelligence spending has surged, thrusting Australian small‑ and mid‑cap technology companies into the limelight. Over the last two years, AI has moved from niche chatter to a principal driver of global capital markets, and a recent research brief points to five ASX‑listed firms poised to reap the benefits of the rising tide in AI infrastructure, software and cloud demand.

Gartner projects worldwide AI spending to reach roughly US$2.6 trillion in 2026, up 44 % from the prior year, while total IT outlays are expected to exceed US$6.3 trillion. AI software alone is forecast to surpass US$450 billion this year, and AI‑related infrastructure spending is estimated at US$1.4 trillion—figures that underscore the scale of investment flowing into data centres, cloud platforms and AI‑enabled applications.

Software‑as‑a‑service (SaaS) remains an attractive model because it delivers recurring revenue with low incremental cost. Once a platform is built, adding new customers requires a fraction of the expense of traditional hardware sales. When AI capabilities are layered onto existing SaaS products, firms can boost user engagement, improve retention and raise average revenue per user, creating a blend of structural growth and margin expansion.

Megaport (ASX: MP1) operates a global network‑as‑a‑service platform that lets enterprises connect to cloud providers and data centres through software‑defined networking. Its FY25 results showed annual recurring revenue of US$243.8 million, a 20 % year‑on‑year increase, and an EBITDA of US$62.3 million. After adjusting for foreign‑exchange and lease accounting changes, the operating result was US$57 million. The company added 115 new data‑centre locations and grew high‑value enterprise accounts by 18 %. Product innovation accounted for roughly a quarter of the ARR growth.

Macquarie Technology Group (ASX: MAQ) offers a diversified portfolio that includes data centres, cloud services, cyber security, telecommunications and government solutions. Its flagship 47 MW IC3 Super West data centre in Sydney’s Macquarie Park reached a major topping‑out milestone and is on track to open in September 2026. The facility is designed for GPU‑heavy workloads and incorporates liquid cooling and direct‑to‑chip architecture. Macquarie increased its debt facilities to US$500 million to accelerate capacity delivery, and FY26 EBITDA guidance is US$114–117 million. Ninety‑five percent of revenue is recurring, and the company holds the only Australian cloud and data‑centre provider certified to the federal government’s strategic sovereign security level.

Dicker Data (ASX: DDR) is one of Australia’s largest technology distributors, supplying hardware, software, cloud solutions and cyber security products to resellers and enterprises. FY25 revenue rose to US$3.88 billion and net operating profit before tax increased to US$124.7 million. Subscription and recurring revenue grew by more than 22 % during the year, reflecting the shift toward cloud‑based services. Management highlighted strong demand linked to AI infrastructure deployments and the upcoming Windows 10 refresh cycle, both of which are expected to support technology spending across multiple sectors.

NEXTDC (ASX: NXT) owns and operates carrier‑neutral data centres that provide the physical infrastructure for cloud platforms and AI applications. The company secured a record 250 MW capacity commitment in a single quarter, raising pro‑forma utilisation to 667 MW and a forward order book of 544 MW. The forward pipeline is projected to generate more than US$1 billion in contracted EBITDA through FY30. To fund this expansion, NEXTDC lifted FY26 capital‑expenditure guidance to US$2.7–3.0 billion and secured over US$8.4 billion in liquidity from equity, hybrid securities and senior debt.

Data#3 (ASX: DTL) delivers enterprise technology solutions, including cloud, cyber security, managed services and consulting. The firm focuses on helping organisations implement and optimise solutions from major vendors, a strategy that has built long‑term relationships with government agencies and large enterprises. Cyber security remains a priority as threats grow and regulations tighten, while cloud migration continues across public and private sectors. The emergence of AI has created new advisory and implementation opportunities, and Data#3’s vendor partnerships position it to benefit from early‑stage AI adoption.

The AI boom is still in its early stages, and infrastructure spending remains high. Small‑cap firms that combine SaaS delivery with AI‑enabled services can capture a share of the growing market, but they face execution risk and market volatility. Investors should assess the quality of the business model, the scalability of the revenue stream and the strength of customer relationships, while remaining aware that AI adoption is still nascent and regulatory developments could affect the pace of growth.
