Reddit Just Had Its Worst Day on the Stock Market, and Google Is the Reason

For twenty years, the deal was simple: you googled a question, added "reddit" at the end, and read the answers for free. That deal is falling apart.

On October 30, Reddit's stock dropped 29% in a single session, its worst day since going public. The trigger wasn't a bad product launch or a scandal. It was a chart going the wrong way: traffic from Google is shrinking, and investors finally noticed.

Blame the AI answers

The culprit has a name: Google's AI Overviews. When Google answers your question directly at the top of the results - often by summarizing Reddit threads, ironically - fewer people click through. Reddit lost more than a million visits per week in October, and its US daily active users declined for the first time.

The whole open web is feeling this squeeze, but Reddit is unusually exposed. A huge share of its traffic is people arriving from search, reading one thread, and leaving. Remove the search click and the model wobbles.

The response: walls going up

Reddit's answer is the one nobody wanted to hear: it's going to test mandatory login to read content, starting outside the US. Read that again. One of the biggest places to read public discussions without an account is preparing to ask for one.

From a business standpoint, the logic writes itself. Logged-in users are worth more, and if Google is going to summarize your content anyway, you might as well stop giving it away to anonymous drive-by readers. From an internet-culture standpoint, it's another brick in the wall around what used to be the open web.

Why you should care even if you don't own the stock

This isn't really a story about one company's bad trading day. It's a story about the mechanism that made the modern web work - search sends traffic, sites stay open - quietly breaking in real time.

Forums died and we shrugged because Reddit replaced them. If Reddit locks its doors too, where exactly do real human answers live? A few of us remember when the answer was "everywhere." It's starting to look like the answer might soon be "nowhere without an account."

We build and catalogue free, open tools here because we think the open web is worth keeping. Days like this are why.
