AI is unbundling the mortgage aggregator

Mortgage aggregation is sold as a bundled service. AI is not replacing the bundle. It is repricing individual components within it. The aggregators that retain pricing power through the next three to five years will be those whose value is concentrated in scarce assets rather than automatable workflows.

This is not the consensus read. Most sector coverage treats AI as a productivity tailwind for aggregators, on the logic that AI tooling makes brokers more productive and aggregators capture some of the upside. The alternative view is that AI is differentially attacking the components of the aggregator value stack, compressing the price of the exposed components and shifting where the durable economics actually sit. The investor reading the next several disclosure cycles should be asking which parts of the bundle survive, not whether AI affects the channel.

The aggregator value proposition to a broker is a bundle. Six components sit inside it: compliance administration, compliance supervisory responsibility, technology platform, training and accreditation, operational support and lender panel access. Brokers pay aggregators for the package. The historical margin economics rest on the broker needing all six.

Each component is differentially exposed to AI substitution. Running the list from most exposed to least exposed:

Compliance administration. Document generation, NCCP-aligned file review, serviceability calculation, fact-find documentation, workflow administration. AI-native tooling can now produce most of this output at a fraction of the historical hand-finished cost. This is where the most visible AI impact sits and where commoditisation is moving fastest.

Technology platform. CRM systems, lead management, lender lodgement integration, marketing tooling. AI-native third-party tooling is reducing what the aggregator-provided platform uniquely delivers. Brokers can increasingly assemble their own stack at lower cost than an aggregator subscription provides. The category is not commoditised yet but the trajectory is set.

Training content delivery. The training material itself, the technical content brokers consume to develop expertise. AI is increasingly capable of producing tailored, on-demand learning material that matches what aggregators package as training programs. The content layer is exposed.

Operational support. The human element of broker relationship management. Hardest to commoditise outright but also the lowest-margin component of the bundle. Sustained exposure is partial. Replacement is not the issue. Margin compression is.

Compliance supervisory responsibility. The regulatory liability layer. The aggregator's credit licence, its accountable supervision of broker conduct, its regulatory relationships with ASIC and APRA, its accountability to the Banking Code Compliance Committee where applicable. AI cannot hold a credit licence. The aggregator that owns the supervisory responsibility holds something AI cannot replicate, and that value may actually increase as AI-generated broker files proliferate and regulators look for accountable oversight. This component is structurally scarce. It may also become more valuable, not less.

Lender panel access. The relationships with lenders, the volume thresholds that unlock pricing tiers, the accreditation pathways for lender access, the negotiating leverage that comes with scale. These remain genuinely scarce. AI cannot replace a panel relationship. The aggregator with the deepest panel access and the highest volume-tier pricing retains the most defensible component of the bundle.

The pattern is clear. The bundle is being repriced from the top of the list down. The scarce assets at the bottom of the list, supervisory responsibility and panel access, are where pricing power will concentrate.

Broker market share has been climbing for a decade. The MFAA's most recent reading, 76.7% of new residential home loans in the December 2025 quarter, is the highest December figure on record. The September 2025 peak of 77.3% sits just above it. The broker channel is now where the majority of new lending flows, which means the channel economics matter more than they ever have.

The consensus view treats this as straightforwardly positive for aggregators. More volume through the channel, more revenue per loan, more total margin. The alternative view is that channel dominance amplifies the unbundling pressure rather than buffering against it. At 50% channel share, aggregator margin compression was a sector-specific issue. At 77%, it is a fintech sector structural issue, and the question becomes which aggregators capture the residual pricing power as the bundle reprices.

AFG (ASX: AFG), the only pure-play listed aggregator at scale, has been responding to this pressure since at least FY22. Its FY25 strategic narrative, published in its October 2025 annual report and AGM materials, explicitly named "harnessing technology" as one of three strategic pillars, with the stated objective of boosting broker productivity. The acquisition of Fintelligence in November 2024 and the launch of the Broker Investments program in FY25 are responses to the same pressure. AFG is doing what an aggregator under structural unbundling pressure would do. It is over-investing in the scarce components of the bundle, lender access, broker network growth and vertically integrated lending through its Manufacturing segment and AFG Securities, while accepting that the commoditised components cannot carry historical margin alone.

The financials are consistent with this read. AFG's FY25 NPAT grew 21% to $35M. Manufacturing segment earnings grew 53%. Distribution segment earnings grew 10%, slower than Manufacturing. The composition of the growth tells the story. The aggregator is shifting value capture upstream and downstream of the exposed components rather than defending margin inside them.

The privately held aggregators (Finsure, Loan Market Group, Lendi Group) and Mortgage Choice (within REA Group) face the same pressure with less public visibility on their response. The investor with capital exposure to private aggregator businesses or to listed parents with aggregator subsidiaries should be asking the same questions of those businesses that AFG's FY25 disclosures begin to answer. Which scarce assets is the business over-investing in. Which commoditised components is it actively walking away from in margin terms. Whether the strategic narrative is responding to unbundling pressure or pretending the pressure does not exist.

The unbundling thesis is a frame, not a prediction. The reader can confirm or disconfirm it by tracking specific disclosures and operational indicators over the next four to eight quarters.

Revenue per broker, where disclosed. Flat or declining revenue per broker against a growing broker channel suggests the bundle is being repriced.

Take-rate disclosure. Net commission retained per loan after broker payment. A downward trend signals component pricing pressure.

Broker retention rates. Lower switching costs imply higher churn. Where retention is disclosed in annual reports or investor materials, monitor the trajectory.

Broker count growth. Aggregators with deep lender panel value and strong supervisory infrastructure will retain attractiveness. Those whose value proposition was concentrated in commoditised components will see slower broker growth or attrition.

Manufacturing and ancillary revenue mix. Aggregators repositioning into vertically integrated lending, white label products, insurance or commercial broking are signalling that the core aggregator bundle alone cannot carry historical margin. Mix shift toward owned products is the structural response. Pace of the shift is the leading indicator.

Technology cost-of-service ratio, where disclosed. Rising technology spend without rising broker satisfaction or productivity is a defensive signal, not an offensive one.

Regulatory and supervisory disclosures. Material credit licence events, ASIC actions or supervisory infrastructure investments at named aggregators. Where compliance supervisory responsibility is the scarce asset, the strength of the aggregator's regulatory standing becomes part of its valuation.

The investor with capital exposure to listed AU mortgage aggregation, to private aggregator businesses or to listed parents with aggregator subsidiaries should expect to see these indicators move materially before they show up in headline earnings.

AI is not replacing the aggregator. It is repricing the components of what the aggregator does, and the durable economics will sit in the parts the technology cannot reach.
