Australian AI-Focused Stocks Offer Exposure to Semiconductors, Defence and Space Themes
Artificial intelligence has become the headline story of the decade, but the forces that fuel its growth extend beyond large‑language models. Semiconductors, edge computing, defence technology, and space infrastructure all drive demand for cutting‑edge chips and systems. In Australia, a handful of listed companies and an ETF let investors tap into these themes.
Weebit Nano (ASX:WBT) stands out as the most advanced intellectual‑property player on the ASX. The company develops Resistive Random‑Access Memory (ReRAM), a non‑volatile memory technology that can be integrated into systems‑on‑chip and discrete packages. ReRAM offers lower power, higher endurance, and faster write speeds than embedded flash. Weebit’s revenue has risen sharply: the first half of 2026 saw record sales, and the company is on track to exceed A$10 million in FY26 revenue. The growth is driven by licensing agreements with Tier‑1 foundries and a design agreement with a product company. The company also signed a partnership with Texas Instruments, indicating that its IP is being considered for commercial use.
BrainChip Holdings (ASX:BRN) focuses on neuromorphic computing. Its Akida architecture mimics biological neural networks and is designed for low‑power edge inference. The company’s revenue jumped 300 % to US$1.89 million in the latest reporting period, but commercial adoption remains early. BrainChip has secured licensing deals with ASICLAND and Frontgrade Gaisler, and has partnered with EDGEAI to bring Akida to smart‑metering applications. The company also announced a partnership with Renesas for spaceflight use, citing incremental learning capabilities that allow new classifiers to be added without full retraining.
Electro Optic Systems (ASX:EOS) bridges space and defence. The firm’s Slinger counter‑drone system is a low‑cost, cannon‑based weapon that can intercept small drones. EOS has recently acquired MARSS’ defence business, expanding its counter‑drone portfolio. The company has won a US$45 million contract in the Middle East and secured two additional unconditional counter‑drone contracts totalling US$45 million. EOS’s market capitalisation has risen to around A$2 billion, reflecting demand for counter‑unmanned aerial systems, directed‑energy weapons, and space‑domain awareness.
Codan Limited (ASX:CDA) is a mature defence and communications supplier. Codan’s radio communications and electronic warfare products are used by the Australian Defence Force, government agencies, and emergency services worldwide. The company’s FY26 revenue target is over A$850 million, and its market capitalisation is close to A$7.85 billion. Codan’s growth is supported by global defence spending and the need for resilient, secure communications.
For investors seeking broader exposure, the BetaShares Global Robotics and AI ETF (ASX:RBTZ) tracks a basket of global leaders in robotics, automation, and AI hardware. The ETF’s underlying index was updated in March 2026 to include humanoid robotics and autonomous systems. Its portfolio is roughly 49 % industrials and 32 % technology, with holdings such as NVIDIA, ABB, Keyence, Fanuc, and Intuitive Surgical. RBTZ delivered an 11.74 % return over the past year.
The Global X Semiconductor ETF (ASX:SEMI) offers diversified exposure to the global semiconductor value chain. The fund tracks the Solactive Global Semiconductor 30 Index, covering chip designers, foundries, memory producers, and equipment suppliers. Its assets under management exceed A$1.1 billion, and it has risen from a 52‑week low of A$17.42 in July 2025 to an all‑time high above A$44 in mid‑June 2026.
The Australian market remains underrepresented in the semiconductor and space sectors compared to the United States, but the listed companies above provide a way to participate in the long‑term growth of AI infrastructure, defence technology, and space infrastructure. Weebit Nano and BrainChip offer potential recurring revenue from IP licensing, while EOS and Codan provide more established defence and communications businesses. RBTZ and SEMI give diversified exposure to the broader AI and semiconductor ecosystems.
In the next five years, the success of these companies will determine whether Australia can become a significant player in global AI, defence, and space technology. Investors should monitor licensing activity, contract wins, revenue growth, and market‑cap performance to assess the trajectory of each firm.
