Remember when investment research was locked behind a $24,000-a-year Bloomberg Terminal paywall? Those days are dying faster than a meme stock in a bear market.
Substack has quietly become the Bloomberg Terminal for people who can’t afford Bloomberg—or who just think the whole gatekeeping thing is ridiculous. And honestly? It’s working. Last month, a research outfit called Citrini Research dropped a dystopian thought exercise about AI’s future on Substack, and it tanked the Dow by 800 points. Not because it was peer-reviewed by the Federal Reserve. Because it went viral on X and everyone decided it was gospel.
This is the new reality: Michael Burry—yes, *that* Michael Burry from *The Big Short*—used to disappear from social media for weeks at a time. Now he’s posting novella-length stock takes on Substack like he’s got something to prove. Ray Dalio is there too. So are dozens of other finance pros who realized they could skip the institutional middleman and talk directly to retail traders who actually want to hear what they think.
“It’s like a stream of consciousness,” says Amrita Bhasin, a retail trader who works in e-commerce. “More authentic than the heavily edited stuff you get from banks.” She’s not wrong. When a professional investor can write without a compliance team breathing down their neck, you get actual opinions instead of corporate word salad.
The appeal is obvious: information that used to cost thousands of dollars is now free (or costs a $5 subscription). A well-timed Substack post gets screenshotted, shared across trading chats, and moves markets before traditional research even gets published. The distance between retail and institutional thinking just collapsed.
But here’s where it gets spicy: not everyone thinks this is a good thing.
James Sixsmith, CEO of a prop trading firm, sees the problem clearly. “The majority of that information is now taken as automatic truth,” he says. That Citrini post? It was basically science fiction—one possibility among many. But it went from Substack to X to “everyone thinks this is definitely happening” in about 48 hours. Retail traders who don’t understand the nuances of what they’re reading are making real money decisions based on posts that might be half-baked speculation.
There’s also the shorting problem. Some Substack writers discuss complex strategies like short selling without always explaining the risks. A retail trader who doesn’t know what they’re doing could get absolutely wrecked following advice meant for professionals.
That said, the genie’s out of the bottle. The democratization of market research isn’t stopping. If anything, it’s accelerating. The next frontier? Substack could build execution tools directly into the platform—turning idea generation into actual portfolio management. Imagine reading a take from Michael Burry and being able to execute the trade in the same app.
For now, Substack is doing what it does best: disrupting gatekeepers. Wall Street’s Bloomberg Terminal monopoly is over. Whether that’s good or bad probably depends on whether you’re the one holding the information or the one finally getting access to it.
