Amazon Rufus, Buy for Me, and Alexa+ — Amazon's Agentic Commerce Strategy

Amazon Rufus, Buy for Me, and Alexa+ — Three AIs Building a Closed Commerce Sphere

In spring 2026, as the battle for agentic commerce leadership intensifies, one fact stands out clearly. Over 20 companies have joined Google's UCP, OpenAI has open-sourced ACP, and Shopify and Stripe champion interoperability — yet amid this chorus calling for an "open future," Amazon alone keeps raising its walls.

What's happening inside those walls, however, is less well understood. Rufus, Buy for Me, Alexa+. Most people know each name individually, but miss the fact that these three operate as a single, coordinated strategy. Overlooking this connection means misreading Amazon's true intent.

Why Amazon Won't Open Up — The Gravity of $68.6 Billion

The most honest answer to this question lies in the numbers.

Amazon's 2025 advertising revenue reached $68.6 billion, growing 22% year-over-year and rivaling AWS as a profit driver. The bulk of this revenue depends on consumers "searching" and "browsing" products on Amazon. Sponsored product ads work precisely because humans visually scan search results and make judgments.

So what happens when AI agents choose products on behalf of consumers? Agents don't "see" ads. They algorithmically select optimal products, bypass sponsored placements, and complete purchases. Welcoming external AI agents onto Amazon would mean undermining this $68.6 billion foundation.

That's why, starting November 2025, Amazon blocked 47 AI crawlers via robots.txt, including ChatGPT and Perplexity. In March 2026, a federal court issued an injunction blocking Perplexity's Comet browser, establishing the precedent that "AI agent access without platform authorization is illegal." Amazon built both technical barricades and legal fortifications simultaneously.

The critical point, however, is that Amazon is not rejecting agentic commerce. Quite the opposite — the most aggressive implementer of agentic commerce within its own walls is Amazon itself. That implementation takes the form of three pillars: Rufus, Buy for Me, and Alexa+.

Rufus — Monopolizing Product Discovery Through a Proprietary Agent

Rufus's growth trajectory proves that agentic commerce is not a theoretical concept but a direct revenue driver.

Over 300 million customers used Rufus in 2025, with monthly active users up 149% year-over-year and interactions up 210%. Measured by what Amazon calls "downstream impact," Rufus delivered $12 billion in incremental annualized sales — roughly 1.4% of Amazon's total $830 billion GMV.

These figures alone are striking, but Rufus's true significance extends beyond sales contribution.

In 2026, Rufus adopted a multi-model architecture combining Anthropic's Claude Sonnet and Amazon Nova, enabling complex multi-step reasoning. The underlying Shopping LLM was expanded 5x, and an AutoBuy feature — which automatically purchases items when prices drop below user-set thresholds — was rolled out for Prime members. The design to complete the entire "research, compare, buy" process within Amazon is progressing steadily.

If external AI agents no longer need to search and compare Amazon's products, Amazon can deliver an agentic shopping experience without disrupting its ad model. This is precisely where Rufus's strategic value lies.

Buy for Me — Pulling External Products Inside the Walls

If Rufus is "the agent for discovering products within Amazon," Buy for Me is "the mechanism for pulling products from outside Amazon into the ecosystem."

Launched as a pilot in April 2025, Buy for Me had expanded by March 2026 to cover over 100 million products from more than 400,000 merchants. When customers find another brand's product on the Amazon app, a "Buy for Me" button appears. Upon tapping, agentic AI sends encrypted name, address, and payment details to complete checkout on the brand's site in the background. The technology runs on Claude Sonnet and Amazon Nova via Amazon Bedrock. The customer never leaves the Amazon app.

What this means is that Amazon's "catalog limitations" have effectively vanished. Previously, D2C brands not listed on Amazon existed outside its ecosystem. Buy for Me unilaterally erases this boundary.

However, the approach has sparked fierce backlash. Over 180 brands reported their products were listed without consent, with complaints about pricing inaccuracies and fulfillment confusion. Opting out requires emailing branddirect@amazon.com, as the default is opt-in. Amazon's "pull into the walls" strategy undeniably comes at the cost of merchant consent and trust.

Alexa+ — Embedding Commerce Into the OS of Daily Life

Where Rufus transforms the smartphone shopping experience and Buy for Me erases catalog boundaries, Alexa+ is tasked with dissolving commerce into the background of everyday life.

Made free for all U.S. Prime members in February 2026, Alexa+ runs on an entirely different architecture from the original Alexa. Powered by Amazon's proprietary LLM and Nova foundation models, it has evolved into an agentic AI capable of executing complex multi-step tasks.

The shift in purchasing behavior is remarkable. Amazon's early data shows Alexa+ users tripled their shopping activity and had 2-3x more conversations. The "Shopping Essentials" hub available on Echo Show 15/21 devices consolidates order tracking, shopping lists, and personalized replenishment suggestions on a single screen.

Alexa+ is also expanding into food delivery (ordering via Grubhub and Uber Eats) and travel planning. Developer documentation for booking features through an Expedia partnership has been published, signaling expansion beyond "shopping" into broader commerce territory.

In a single phrase, Alexa+'s strategic position is about building a world where purchases complete before people realize they're shopping. When the milk in your fridge runs low, it suggests an order automatically; when a price drops, it buys automatically. This "ambient commerce" eliminates the very motivation for consumers to search on Google.

The Three-Pillar Strategy Structure

What emerges from this table is that the three products don't compete with each other — they divide responsibility across different layers of the purchase funnel.

Rufus handles "deciding what to buy." Buy for Me handles "not caring where it comes from." Alexa+ handles "not even being aware you're buying." Combined, these three layers allow Amazon to contain the entire consumer purchase process — from upstream to downstream — within its own ecosystem.

While the open protocol camp envisions "a world where AI agents freely traverse multiple merchants," Amazon is building "a world where traversal is unnecessary." Block outside agents, deploy inside agents at every touchpoint. Offense and defense unified.

Can This Strategy Last? Three Structural Risks

Amazon's closed strategy has clear rationality, but it also carries structural risks.

First, regulatory risk. In February 2026, NIST launched an AI agent standardization initiative, and the EU is developing AI Act guidelines for commercial transactions. The likelihood of platform-level agent exclusion being deemed "anti-competitive" grows with time.

Second, merchant defection. The consent issues around Buy for Me damage brand trust. With Shopify opening Agentic Storefronts to millions of merchants and Walmart deploying Sparky across every AI channel, D2C brands are gaining alternatives beyond Amazon.

Third, as CEO Andy Jassy himself has acknowledged, "I expect we'll partner with third-party agents over time" — a statement suggesting Amazon itself isn't fully committed to a permanently closed strategy. The company is reportedly hiring for strategic partnerships in agentic commerce, possibly preparing to adjust wall height in the future.

What This Means for Merchants

Facing Amazon's three-pillar strategy, merchants need to pursue "Amazon optimization" and "open protocol readiness" simultaneously.

On the Amazon side, structuring product data optimized for Rufus is the top priority. Since Rufus uses a Q&A-style interface for product recommendations, merchants need to describe "why this product is optimal" in machine-readable formats, beyond traditional SEO keyword optimization. For Buy for Me, establish a system to regularly check for unintended listings and control listing conditions.

Simultaneously, preparation for Google's UCP and OpenAI's ACP should proceed in parallel. There's no guarantee Amazon's walls will lower in the future, and ignoring the agent economy growing outside those walls means leaving opportunities on the table.

Summary

Rufus, Buy for Me, and Alexa+ are not independent products — they are the three pillars of Amazon's closed agentic commerce ecosystem. Protecting $68.6 billion in advertising revenue while delivering agentic purchasing experiences inside the walls — this strategy is highly rational in the short term, but faces dual pressure from regulatory waves and the expanding open camp.

Predicting when and how these walls will open is difficult. What is certain, however, is that only merchants prepared for both inside and outside the walls will survive the agentic commerce era.
