Spending in the region, excluding Japan and China, is expected to reach US$28.2 billion by 2027.

Nuix can handle extremely large data sets, and its software is designed to operate at a forensic level, ensuring that data is collected and analyzed in a way that is legally sound and defensible in court. This gives Nuix a significant market share within the law enforcement and legal communities.
4. BrainChip (ASX:BRN)
Market cap: AU$380.77 million
Share price: AU$0.18
BrainChip is the company behind Akida, a revolutionary digital neuromorphic chip that’s built with a spiking neural network, a type of artificial network that mimics the way messages are passed between neurons in the human brain.
Because the AI is inside the chip, the chip can learn on its own and is not reliant on the cloud or other networks. According to the company, this makes it much more secure and reduces latency.
In June 2024, the company released a white paper for its newly developed technology, TENNs-PLEIADES, an efficient AI processor that can perform complex tasks like decision-making, object recognition and data analysis. BrainChip's lowest-power version of the chip, called Akida Pico, was released on October 1 of that year.
Unlike Akida, this chip is designed for spatiotemporal classification and detection using event-based data, making it particularly well-suited for low-latency applications such as self-driving cars.
BrainChip showcased its advancements in event-based vision at Embedded World 2025 and announced a partnership with Information System Laboratories focused on AI-based radar research solutions based on Akida.
5. Weebit Nano (ASX:WBT)
Market cap: AU$333.61 million
Share price: AU$1.46
While Weebit Nano isn't directly developing AI applications or algorithms, its core technology, Resistive Random-Access Memory (ReRAM), is positioned to be a crucial enabler for the future of AI, particularly in the realm of edge AI and neuromorphic computing. ReRAM's low-power operation and potential for high-density make it a promising memory technology for building neuromorphic chips.
Weebit Nano's target markets are heavily driven by AI, such as autonomous vehicles, robotics and advanced Internet of Things devices. As of March 2025, the company is collaborating with companies like Embedded AI Systems to demonstrate the advantage of ReRAM in ultra-low-power applications.
