Fewer customers from search, a new door for AI agents: I did the math on Upwork

Upwork's and Reddit's Q3 2026 results filed with the SEC (the US stock market regulator), and the official notice for Upwork's MCP server, reviewed on 05/11/2026 around 11:30 UTC (universal time).

Reddit wrote it at the end of October, Upwork four days later: search engines are sending them less traffic. Upwork has opened another door, for AI agents. How much does the new door bring in, and how much does the old one cost? I have both receipts.

In short

• In Q3 2026, Upwork processed $914.1M (million dollars) of projects and services across its platforms, versus $1,016.7M a year earlier: $102.6M less. Among the causes it cites: search engine optimization, which brings it fewer customers without advertising.
• In August 2026, it launched an MCP server: a connection that lets an AI agent write and publish a job post, search for freelancers and invite them, from a compatible AI tool.
• Upwork estimates that this door brings in, at its current pace, more than $3M a year, or at least $0.75M a quarter, in tokens that freelancers pay to apply. Over the same quarter, its revenue fell by $16.1M year over year.

The smoking gun

Reddit kicked things off on 10/29. In its shareholder letter, it writes that its search referral traffic "was down meaningfully in Q3," then that in October it is losing more than a million visits a week on average from search engines. I already did the math on that, stock included: Reddit drops 29% in one session. Just one line to add. In its quarterly report, Reddit names Google among the competitors that put AI-written answers at the top of their search engine, which may "reduce the likelihood that users click through to Reddit".

Upwork follows on 11/02. It's a freelance marketplace: a client posts a project, independents apply, and Upwork takes a fee along the way. Its quarterly report lines up three causes for the drop in its business volume: the effect of AI on certain freelance categories, economic uncertainty, and "changes in the search engine optimization environment" that weighed on organic client acquisition. Further on, it spells it out: "AI-generated search alternatives and AI-related and other changes to search engine results pages have emerged recently, affecting new customer acquisition and resulting in changes to our customer acquisition strategy.".

The word "Google," though, isn't there. I searched for it in the press releases of the last two quarters and in the report. Zero in the press releases. Once in the report, for the Google Play app store. Upwork talks about search engine optimization and search engine results pages, without naming anyone. I'm copying what's written.

The scene

Picture this. You're a freelance graphic designer. Before, a small-business owner typed "freelance logo designer" into a search engine, landed on Upwork, posted their project, and you applied. Let's say today they ask an AI instead. It answers. They don't click.

Upwork has plugged its marketplace into the AI itself. In my scenario, the owner tells their assistant: "Find me a designer for a logo." That's the MCP server, launched in August 2026: clients and freelancers hand AI agents the job of finding talent, finding projects and managing part of the work, without leaving their tool.

The notice published by Upwork, in its 10/28 version (not necessarily the launch one), details the procedure:

• the agent writes the post, saves it as a draft, then publishes it if the client explicitly asks;
• it searches for freelancers, reads proposals, can shortlist some and send invitations;
• the notice requires the agent to ask for the client's approval before every action that writes something on Upwork, and a second approval before publication.

Hiring without going through the site? Almost. The last step stays with Upwork. A contract offer prepared by the agent isn't sent: the client gets a link, and it's on Upwork that they review, fund and send it. Same rule for anything that moves money or binds a party.

On the freelancer side, the agent can also apply for you. It shows you the number of Connects the application costs, and your balance, before sending. Connects are the tokens freelancers buy to respond to a project. That's where the money is.

On the agents' side, a release published on 05/11, Nous Research's Hermes Agent 0.23, lets an MCP server declare the price of each of its tools and a spending cap per conversation: the agent shows the cost of the call and the total already spent, and asks before going over the cap.

The bill

First, what the old door costs. Upwork doesn't quantify the share of search in its losses, so I'm putting down the total, all causes combined.

• Business volume (everything clients spent on its platforms, projects and services): $914.1M in Q3 2026, versus $1,016.7M a year earlier. $102.6M less, −10.1%.
• Revenue (the part Upwork keeps for itself): $185.6M versus $201.7M. $16.1M less, −8%.
• Active clients: 717,000 at the end of September 2026, versus 794,000 a year earlier. 77,000 fewer. For every 100 active clients a year ago, there are roughly 90 today.

Next, what the new one brings in. Upwork reports nearly 50 million requests made by AI agents, and weekly active users multiplied by 20 since launch. In money: more than $3M a year, as an annualized estimate, of Connects revenue passed through the server.

I'm putting the two on the same period, assuming that pace holds. $3M a year is at least $0.75M a quarter. Against that, $16.1M less in revenue over the quarter. The new door weighs about 5% of that hole. And that money comes from freelancers, who pay to apply, not from the clients the agents were supposed to bring in.

Last line, sales and marketing expenses: $33.8M this quarter, versus $35.0M a year earlier, or $1.2M less. That budget isn't going up.

Upwork's boss, Hayden Brown, calls AI agents "a new class of client". On paper, why not. On the invoice, what the agents' door brings in, in plain terms, is Connects: the equivalent of at least $0.75M a quarter, paid by freelancers. I have the receipt.

What we don't know yet

• The share of search in the decline. Upwork gives three causes and no weight for each. Impossible to say how much of the $102.6M comes from search engines.
• How many clients arrive through agents. Requests, a multiplier with no starting point, Connects. No number of projects or contracts signed through this channel.
• What comes next. Upwork expects these factors to keep weighing on its volume, clients and revenue through the end of 2026, and forecasts $169M to $177M in revenue for Q4.

Key terms

• MCP (Model Context Protocol): an open standard that lets you plug a service into an AI assistant, so the agent can read and act inside that service.
• AI agent: an assistant that doesn't just answer, it chains actions (search, write, send) on someone's behalf.
• GSV (Gross Services Volume): at Upwork, business volume, all the money flowing through its platforms, including client spend and paid services.
• Connects: the virtual tokens freelancers buy to apply to a project or promote themselves on Upwork.
• Organic acquisition: clients who arrive without paid advertising, for example through a free search result.
• Annualized estimate: the recent pace of revenue scaled up to a year, not a sum already collected over a year.
