Amazon's planned acquisitions of iRobot and One Medical are emblematic of Andy Jassy's hunt for a so-called fourth “pillar”, beyond AWS, Prime, and Marketplace
Amazon has snapped up robotic vacuum maker iRobot, undaunted by antitrust concerns. But first:
Context & Ripple Effects
The pillar-hunt framing has a long tail: a CB Insights deep dive had already mapped Amazon building new pillars in AI, next-gen logistics, and enterprise cloud back in 2017, so iRobot and One Medical read as the next candidates after AWS, Prime, and Marketplace. What followed shows how contested that route became — the FTC opened a review of the $1.7B iRobot takeover within weeks, examining whether it illegally boosts Amazon's connected-device market share.
The arc since then sharpens the stakes: the European Commission concluded the (reduced) $1.4B deal may restrict competition and iRobot shares fell ~18% on the news, and by 2024 Jassy was publicly criticizing US and EU regulators for blocking the deal, arguing they trust large Chinese companies more than Amazon with maps of home interiors.
First-order effects
- Amazon's fourth-pillar strategy hits a regulatory wall immediately: the FTC review puts the iRobot acquisition itself at risk, and any One Medical move inherits the same scrutiny over whether pillar-building via acquisition is legal.
- iRobot becomes the exposed party — its standalone future and share price are now hostage to a deal Amazon can walk away from, as the ~18% drop on the Commission's objection showed.
Second-order effects
- The home-data angle raises the bar for every connected-device seller: critics flagged that iRobot hands Amazon 'another vast and intrusive set of data about people's homes,' giving rivals a privacy-and-data-accumulation argument to deploy against Amazon's device ambitions.
- Other big-tech acquirers face a repriced M&A environment — buying a category leader as a strategic beachhead now carries a real probability of multi-year regulator vetoes, pushing companies toward smaller tuck-ins or organic builds.
Third-order effects
- If the pattern holds, the mega-acquisition stops being a viable tool for constructing new platform pillars, forcing Amazon-class companies to grow the next AWS or Prime organically — a structural shift in how dominant platforms diversify.
- Antitrust authorities are effectively gaining a veto over big tech's corporate strategy, not just individual deals: which 'pillar' a company like Amazon is allowed to build through M&A becomes a regulatory decision rather than a boardroom one.
The trend: Big-tech platform expansion through acquisition is colliding with antitrust regimes willing to veto pillar-building deals outright, as the iRobot saga shows.
