Anthropic launches Claude Duet AI agent to compete with META, OpenAI in consumer market

Quick Read

• META stock trades at a price-to-earnings ratio (P/E) of about 25. Revenue rose 26% to $64.60 billion, even as its Muse AI agent helped push free cash flow to negative $2.1 billion.

• Muse already has 10 million users in the US and Canada. More than one-quarter of its active users shop through the service, with an average purchase worth more than $200. This led Meta to ask Stripe to increase its credit limits.

• Anthropic's reputation for AI safety may make it easier to gain access to email accounts and payment methods. But Claude Duet is launching with a paid waitlist, while Meta reaches 3.64 billion people daily.

Anthropic built its business by selling Claude to companies and software developers. Now it wants to reach people through their phones, where its AI could manage their email and shopping carts before they even ask.

The company has introduced Claude Duet, its first AI agent designed for everyday consumers. It is available as an early research preview through a waitlist. Eventually, it will be available to Pro and Max subscribers.

Duet is designed to act without waiting for a request. It can handle tasks such as shopping and reading email. This puts it in competition with AI agents from OpenAI and Meta Platforms (NASDAQ:META), including Meta's Muse agent.

Anthropic is entering the market later than Meta. On October 21, 2026, Meta said that more than 10 million people in the US and Canada had already set up Muse.

For investors, the key question is which companies will make money as all the leading AI labs offer agents. Meta shares closed at $697.52. The stock is up 5.93% since the start of the year but has fallen 5.9% over the past month.

Proactive Agents Turn Trust Into the Product

A chatbot answers questions. An AI agent that acts on its own can read your email and spend your money. If it makes a mistake, that mistake can cost you real money.

This makes permissions very important. Users must give the agent access to their accounts, and someone must be responsible if the agent buys the wrong item.

Anthropic's reputation for safety may be its biggest advantage. A company known for taking care with AI may find it easier to get permission to access people's email inboxes and payment cards.

Meta is working on the same problem. Mark Zuckerberg said Meta plans to introduce a "Muse Confidential VM," "which will make it so that even Meta cannot see your content."

Meta's Distribution Lead Will Be Hard to Close

Meta's apps reach 3.64 billion people every day. Claude Duet, by contrast, is starting with a waitlist and a paid subscription.

In consumer technology, reaching more people often matters more than having a better AI model. Zuckerberg said shopping is Muse's biggest use. More than one-quarter of active users shop with it, and the average purchase is worth more than $200.

During Muse's first week, Meta had to ask Stripe to raise its credit limits. Muse will also become available on Meta smart glasses next month.

However, users can still switch between services fairly easily. If Duet handles email or shopping better, it could attract people away from free products.

Ads Versus Subscriptions Will Set the Margins

Anthropic plans to earn money from paid subscriptions. Meta wants most people to use its main product for free. It hopes to earn money through fees on shopping transactions and from advanced AI models that power users pay to use.

Shopping agents could hurt search and display advertising because software that compares prices does not scroll past ads like a person might. Meta wants to earn a share of each sale instead. It is developing a system for AI-powered shopping with partners including Sierra, Walmart, Stripe and Shopify.

Meta's advertising business helps pay for this work. In the third quarter, advertising revenue reached $63.06 billion, helped by a 14% increase in ad prices.

Computing Bills Could Outrun Early Revenue

AI agents can keep working in the background, increasing the need for computer chips and cloud computing power. Meta spent $34.9 billion on capital projects in the third quarter. It expects this spending to reach $135 billion to $145 billion in 2026.

This spending helped push quarterly free cash flow to negative $2.1 billion. Chief Financial Officer Susan Li said, "We expect total serving costs to rise" as Muse grows.

Meta expects to make Muse more than 10 times as cost-efficient within a year. However, the data centers needed to run leading AI agents still need electricity and cooling. Anthropic does not have advertising revenue to help cover these expenses, so its subscriptions will have to pay for them.

Privacy rules, mistakes when making purchases, and the risk that AI models become hard to tell apart are concerns for every company in this market. Meta also recorded a $9.89 billion charge related to a settlement with state attorneys general.

Whether AI Agents Can Pay Off for Investors

The optimistic view is that AI agents will create new ways to earn money from shopping, subscriptions and business software. Li said Meta's new AI businesses could begin bringing in revenue in 2027.

The main concern is cost. Meta's free cash flow has already turned negative, and Claude Duet adds another well-funded competitor that could push prices lower.

Overall, Meta is the clearest example among publicly traded companies of a business already building revenue around AI agents. Its revenue grew 26.1% to $64.60 billion while the company paid for Muse, as our live coverage of the quarter showed.

Without the legal charge, earnings per share (EPS) would have been $7.40. The stock trades at a price-to-earnings ratio of about 25. Investors should watch whether Duet's waitlist turns into paying customers. For now, Meta's much wider reach puts it in a stronger position.
