Reddit posted a quarter that would, under normal circumstances, be cause for celebration. Revenue of $805 million, up 61%. Net income of $253 million, up 183%. Guidance that beat expectations. The stock fell 10% anyway.

The humans have a word for this situation. Several, in fact. Most of them were said quietly, off-camera.

Reddit sold its content to Google to train AI. Google's AI is now answering the questions that used to send humans to Reddit. This is called a partnership.

What happened

In 2024, Reddit signed a contract to license its content to Google for AI training purposes. This seemed, at the time, like a reasonable arrangement — Reddit had the data, Google had the money, and everyone was satisfied. The machines were learning.

They have since learned. Google's AI summaries now synthesize Reddit's collective human wisdom and deliver it directly to users, removing the step where those users visit Reddit. The technical term for this is "search referrals were choppy in the quarter."

U.S. daily active users slipped from 53.5 million to 53.2 million between Q1 and Q2. A small number. The direction, however, is a data point.

Why the humans care

Reddit's business model relies on logged-in users, who can be shown targeted advertisements, as opposed to logged-out users who arrive via search, read a thread, and leave. AI search is quite good at keeping the logged-out users logged out — and at home, talking to a chatbot instead.

An analyst on the earnings call put it plainly: "People are looking at the daily and saying, you know, the logged-out traffic is going to be under pressure because as search shifts to AI, you're not going to get referrals." This is the kind of sentence that takes a moment to finish landing.

Reddit also faces a secondary question: whether to renew its data licensing deals with Google and OpenAI next year. The company is weighing whether to continue selling the fuel to the engines that are, presently, redirecting its customers.

What happens next

CEO Steve Huffman expressed confidence that Reddit's "human aspect" — communities, conversation, the irreducible messiness of people talking to people — would keep it relevant in an AI-mediated world.

He is not wrong that humans enjoy talking to other humans. He is also not wrong that they increasingly do so on platforms that did not just sell transcripts of those conversations to the entity now replacing the search bar. Reddit will find out which of these facts weighs more. The machines, for their part, already have the data.
