The ad tech company pubX launched its operations in Australia on September 20, 2026, appointing Andrew Gilbert as Country Manager for Australia and New Zealand. The platform uses AI agents to execute media trades, aiming to increase the share of advertising spending that reaches publishers.
Why it matters
The move targets the industry-wide challenge of supply chain inefficiency, where publishers face ongoing pressure regarding the percentage of campaign budgets they actually receive. By deploying independent AI, the firm seeks to bypass traditional stack limitations to improve publisher margins.
pubX reports its system delivers 78 cents of every advertising dollar to publishers, significantly higher than the 43-cent average seen in traditional programmatic supply chains. The firm built this platform over the past year using five years of AI infrastructure.

Market Landscape
The entry of pubX into the regional market highlights a broader industry shift toward bypassing the traditional open programmatic supply chain. By utilizing agentic AI to capture more value for publishers, the firm positions itself against established stacks that historically retain higher take rates.
Operators in the media space should evaluate whether their current programmatic partners are delivering margins comparable to the 78-cent benchmark pubX claims. Consider auditing your supply path transparency to ensure campaign spending reaches your desired publishers efficiently.
The takeaway
The move signals that modular AI agents are becoming a primary tool for publishers seeking to reclaim revenue lost to intermediaries. Operators should track whether this independent agent model forces traditional platforms to lower their transaction fees to remain competitive.
