How to Spot Viral Trends Before Everyone Else
Stop writing about dead topics.
I am going to commit the cardinal sin on Substack and take a moment to talk about X…
…because X is the real-time pulse of the internet.
Every trending topic, every hot take, every industry debate plays out on the timeline hours before it hits anywhere else. By the time something trends on LinkedIn or shows up in a newsletter roundup, X already moved on.
This is a massive advantage for Substack writers who know how to use it.
You’ve probably spent hours hunting for topics, scrolling through feeds, trying to figure out what your audience actually cares about this week.
Meanwhile, the answer is right there. Updated every hour. Free.
Knowing that X is a goldmine means nothing if you are mining the wrong topics at the wrong time.
Let me tell you who actually gets read.
Not the most original writer. Not the smartest expert in the room.
The person who spots the wave first.
Why You Keep Writing About Dead Topics
Last week proved it perfectly.
Dan Koe published “How to Fix Your Entire Life in One Day” on X. It went nuclear. A masterclass in timing and packaging. Within 48 hours, newsletter writers everywhere were publishing their own versions of the same theme.
And they got mediocre results.
Every single one of them was already too late.
Here is what 20 years of intelligence work taught me about information:
THE VALUE OF INTEL DECAYS BY THE HOUR.
In the field, we called this “perishable intelligence.” A piece of information that is gold at 6 AM is worthless by noon. The same dynamic plays out on X every single day.
By the time you see a trend, it is already dying. The conversation moved on hours ago and the audience is saturated. That newsletter you spent 3 hours writing? It is competing against 50 other versions of the same idea, and your readers have already seen the take.
You are invisible.
The Real Problem: You Have a Business to Run
You have a business to run.
You are heads-down building. You are researching, writing and in client meetings. You are living an actual life outside of social media. You do not have 6 hours a day to doom-scroll X, staring at the timeline, waiting for a hit.
So you stay invisible. Stuck writing about topics that peaked days ago.
But what if you could get there first?
Imagine knowing the conversation is shifting before the average user even opens the app. Not after everyone piles on. Not when you are the 15th newsletter with the same hot take.
Before.
Imagine having a radar system that pings you the moment a topic starts to heat up on X. This allows you to develop your own angle, your own framework, your own intellectual property. Then you publish it on Substack while the topic is still fresh.
When you do this, you stop being a copycat.
You become the source.
People start copying YOU.
Why Grok (And Not ChatGPT or Claude)
We are going to build an automated radar using Grok.
Why Grok and not ChatGPT or Claude?
ACCESS TO THE FIREHOSE.
Grok has direct access to the X live feed. It can see likes, reposts, and momentum shifting in real-time. It is the only tool capable of spotting a trend the moment it starts to spark. It can differentiate between a viral meme (useless to you) and a viral industry shift (highly valuable for your newsletter).
Here is the exact system.
How to Set Up Your Daily Intel Report
We are going to use a feature most people are sleeping on: Grok Tasks.
This allows you to automate a prompt to run on a schedule. A Daily Intelligence Briefing hits your inbox every single morning before you start work. You scan it in 5 minutes. You know exactly what your audience is talking about on X right now.
Then you write about it on Substack while the iron is hot.
Step 1: Access the Command Center
Head to the Grok tab on X (or the mobile app). You will need Premium+ or SuperGrok to unlock the full context window needed for deep analysis.
Step 2: Configure the Task
Click your profile icon and select “Tasks.”
Name: Daily Niche Intel
Schedule: Daily at 6:00 AM or any other timeframe you choose
Delivery: pick your delivery method of choice
Step 3: The Prompt Engine
This is where the magic happens. A generic prompt gets generic results. We need a prompt that filters out the trash and extracts the gold.
Copy this exactly:
The Prompt:
“Act as a senior market analyst. What are the top 10 trending topics and most engaged posts in the [YOUR NICHE, e.g., SaaS Marketing] niche on X right now?
Focus strictly on the last 24 hours. I need high-value intel, not distractions.
Prioritize these specific triggers:
High-engagement posts (likes, reposts, replies) from thought leaders
Posts mentioning key terms like [INSERT 5-10 SPECIFIC KEYWORDS HERE]
Emerging debates or contrarian takes that are getting heat
Announcements from major companies or influencers in this space
For each trend, provide:
The Headline: A 1-sentence summary of the trend
The Proof: Engagement stats (approximate) and why it is moving
The Source: A direct link to the catalyst post
The Angle: Suggest one contrarian or value-add angle I could take on this topic
Format this as a clean executive summary. Exclude ads, memes, giveaways, and off-topic political posts.”
Customize Your Keywords
The prompt above works, but it only becomes a weapon when you customize the KEYWORDS section.
Generic keywords get generic results. You need to track what people are fighting about NOW in your specific corner of X.
Do not leave this blank. List the 5-10 terms that define your niche.
Three Ways to Turn X Trends Into Substack Posts
Now you have the report. 6:05 AM. Coffee in hand. You see that a specific topic is trending because of a new announcement, a controversial take, or a leaked demo.
What do you do?
You do NOT just tweet about it. That is low value and gets lost in the noise.
You take it to Substack where you can go deep.
You have three plays:
1. The Synthesizer Post
Take the trending conversation from X and curate the top 3-5 perspectives into a comprehensive breakdown for your newsletter readers.
“Everyone on X is talking about [topic]. Here is what you actually need to know.”
This positions you as the hub of intelligence. You are not just commenting. You are synthesizing the chaos into clarity. Your readers share posts that make them look informed.
2. The Contrarian Post
Find the flaw in the dominant narrative on X. Write the newsletter that challenges it.
If everyone on X is saying “AI Agents will replace workers,” you write “Why AI Agents Will Create More Jobs Than They Destroy.”
Contrarian takes get quoted, debated, and shared. You become the counterpoint people reference when the conversation continues.
3. The Case Study Post
Take a trending topic from X and apply it to real life. Do not just report the news. Show how you are using it with screenshots, workflows, and results.
“Everyone is going crazy over [new feature]. I spent 2 hours testing it. Here is the exact workflow I built.”
Case studies convert readers into subscribers because they see you as someone who DOES. This is the format that builds the most trust.
The Morning Workflow: From Intel to Published in 60 Minutes
Here is how this looks in practice:
6:00 AM - Grok report lands in your inbox
6:05 AM - You scan it over coffee, identify 1-2 topics with heat
6:15 AM - You outline your angle (synthesizer, contrarian, or case study)
7:00 AM - You publish on Substack while the topic is still trending
Rest of the day - Your post gets shared because you were first with depth
Compare this to most newsletter writers who are researching topics that peaked 3 days ago and wondering why their open rates are dropping.
X is the Radar. Substack is the Distribution
X is the early warning system for what your audience cares about.
Substack is where you go deep on it.
Most newsletter writers have this backwards. They research in isolation, write in a vacuum, and publish into silence. They are reacting to trends that already passed.
With this system, you stop reacting.
You start predicting.
Next time something explodes on X, you will not be scrambling to cover it days later. You will see the wave while it is still forming. You will have time to develop your own angle. You will publish while everyone else is still tweeting.
The window is open right now.
Build the radar. Catch the wave early. Write the newsletter while the conversation is still hot.
That is a fundamentally different position to operate from.
This is the kind of tactical breakdown I send to premium subscribers every week.
Prompts you can copy. Systems you can build in an afternoon. No theory. Just implementation.
This is how people grow and do big things. Excellent article.
What an incredible hack! Thank you for this Ryan.
