Aggregation Theory in 2026

Ben Thompson's aggregation theory in one line: in markets with high distribution costs and high user fragmentation, the player who controls demand-side relationships wins the entire stack.

Where it's playing out now

• AI dev tools. Cursor, Claude Code, Copilot — whoever owns the top of the funnel for "where developers write code today" captures the orchestration layer above every model.
• CRM. HubSpot is the demand-side aggregator for SMB CRM. Salesforce is the enterprise version. The middle is being squeezed.
• Health benefits brokerage. Gusto-style payroll/benefits platforms aggregate the long tail of small employers and become the buyer for upstream insurers.

What I'm watching

The next category to consolidate via aggregation will be vertical AI for SMBs. Whoever cracks the GTM motion to onboard 100,000 dentists / lawyers / restaurants gets the demand-side pricing power.

The trade

Long the aggregator. Short the supplier whose primary customer is being aggregated. This is structurally what made Amazon vs. brand-name CPGs the trade of the 2010s.
