The Death of the Aggregator: How the Agentic Web Will End the Platform Tax

Booking.com takes around $5.8 billion in profit every year. That money comes directly from hotels that have no realistic alternative but to pay.

This is the most successful toll road ever built.

Not a physical one. A digital one. It quietly extracts billions from businesses simply for being found.

Booking Holdings, which owns Booking.com, Priceline, Agoda, Kayak, OpenTable, and others, generated $23.7 billion in revenue in 2024. Almost all of it came from commissions. Typically 15 to 25 percent on every booking, table reservation, or rental.

The company controls roughly two thirds of the global online accommodation market. Together with Expedia, it dominates travel bookings across Europe and the US.

This is not a marketplace. It is a tax on access.

How Aggregators Took Control

Early on, aggregators solved a real problem. Discovery was hard. How do you find a hotel in Porto or a plumber in Chicago?

They built large databases, invested in SEO, became familiar brands, and made themselves the default starting point. Businesses signed up because they had to.

Then something changed. Aggregators stopped facilitating discovery and started owning it.

Once they controlled where customers began, they controlled the relationship. Once they controlled the relationship, they could charge whatever the market would tolerate.

Commissions rose. Visibility became pay to play. Sponsored listings became mandatory. A nominal 15 percent fee often turns into 25 percent once promotions are included.

And leaving is not a real option. Walk away and bookings disappear.

The Cost of Dependency

A hotel charging $200 a night might lose $40 per booking. A modest 50 room hotel at 70 percent occupancy can easily send half a million dollars a year to Booking.com. For many hotels, that exceeds their total profit.

The same pattern exists elsewhere.

Restaurants pay per cover fees just to manage reservations. Tradespeople pay for leads that often do not convert. Food delivery apps take up to 30 percent of each order.

The model is simple. Become unavoidable, then skim every transaction forever.

What Aggregators Actually Provide

In return for these fees, aggregators mostly offer:

• A listing the business maintains itself
• Basic booking software
• Access to customers who would often find the business anyway
  
  

What they really sell is the threat of invisibility. Pay or disappear.

They argue this is marketing and trust. In reality, most trust comes from familiarity funded by the very commissions businesses are paying. It is a closed loop that benefits the platform above all else.

The Data Capture

There is a deeper problem. Aggregators own the customer.

They keep the email, the preferences, the booking history. The business gets a single transaction. The platform gets lifetime value.

Hotels cannot directly market to past guests. Restaurants cannot personalise outreach. Over time, businesses become interchangeable inventory while the platform accumulates all the intelligence.

The Information Problem

Aggregator data is third party data. It is often outdated, incomplete, or wrong.

Photos mislead. Descriptions lag reality. Reviews are noisy. The platform is not accountable because it never experiences the service itself.

Volume matters more than accuracy.

The Agentic Web

Now imagine a different setup.

Your personal AI assistant needs a hotel in Barcelona. Instead of querying an aggregator, it talks directly to hotels.

Each hotel has its own agent that understands availability, pricing, amenities, and context. Your assistant contacts hundreds of them at once and compares real offers in real time.

No middleman. No commission. No platform owning the relationship.

This is dynamic aggregation. Aggregation happens only when needed, then disappears. No permanent toll road is built.

Why This Is Better

For businesses, margins return and customer relationships are direct again.

For consumers, prices drop, matches improve, and information is richer and more accurate.

For the market, small players compete on quality rather than ad spend. Innovation returns because there is room to invest.

Personalisation Without Surveillance

Your assistant already knows your preferences. It can share a minimal, anonymised profile with service agents.

Hotels respond with tailored offers in their own voice, using their own brand, not a flattened listing in a grid.

Information is first party. No scraping. No summaries. No guesswork.

A Different Trust Model

Booking through an aggregator requires trust in the platform’s incentives, algorithms, and summaries.

Direct agent communication requires trust only in two places: your assistant, which works for you, and the business agent, which represents itself.

Aligned incentives. Authenticated sources. Clear accountability.

What Happens Next

This transition will not be instant.

Early users will compare aggregators with direct offers. Businesses will realise they can capture demand without commissions. Personal assistants will increasingly prefer direct channels because the results are better.

Aggregators will either shrink into low margin infrastructure providers or slowly fade.

The End of the Toll Road

For twenty years, aggregators monetised discovery by owning it.

The Agentic Web routes around them.

When businesses can speak for themselves and consumers can negotiate directly through their own assistants, permanent toll collectors no longer make sense.

That is not an efficiency gain. It is a structural correction.
