We Tracked Every LinkedIn Post from S&P 500 CEOs. Here's What Actually Works.

Omniscan ·

LinkedIn has 65 million decision-makers and 10 million C-level executives on the platform. That is an enormous concentration of senior buyers, investors, and partners all scrolling between meetings. If your CEO can capture even a fraction of that attention, you are reaching an audience that no paid campaign can replicate.


So, we decided to find out which CEOs are actually doing it well, and what separates them from the rest.


This is the second instalment in Omniscan AI's ongoing influence research series. After our VC influence rankings earlier this year, we turned our attention to the big leagues: the S&P 500. Our team tracked every LinkedIn post from 259 S&P 500 CEOs over six months — 2,000 posts in total — and scored each executive using our Benchmarker methodology, a weighted composite of total likes, comments, posting frequency, and consistency across the period.


You would think running a trillion-dollar company would be the hard part. Turns out, writing a decent LinkedIn post might be harder.


The Quality vs. Quantity Myth


The single most important finding from the data is that volume does not drive influence.


Jamie Dimon posted five times in six months. Five. He still ranked fourth overall. The man posts like a central banker — rarely, deliberately, and with weight behind every word. His top-performing post was not about JPMorgan's earnings or a quarterly update. It was about America's role in the world and a new investment initiative. That one post alone generated more engagement than most CEOs managed across their entire six-month output.

This is worth sitting with. In a platform culture that rewards consistency and frequency, Dimon's approach is a direct challenge to conventional LinkedIn wisdom. He proves that if what you say genuinely matters, you do not need to say it often.


At the other end of the spectrum, Ravi Kumar S was the hardest worker in the dataset — 29 posts over six months — and came eighth. Meanwhile, the median top-25 CEO posted just 10 times. Less than twice a month. Your average LinkedIn influencer does that before breakfast.


Nadella Is in a League of His Own


Satya Nadella's dominance is difficult to overstate. 156,000 likes from just 24 posts. His Benchmarker score of 181,000 is more than double the third-ranked CEO. Andy Jassy and Sundar Pichai round out the top three, but the gap between Nadella and everyone else is enormous.


What makes Nadella different is not just reach — it is that he consistently blends product announcements with a broader narrative about where technology is heading. His posts feel like they come from a person with a worldview, not a corporate account with a content calendar.


It Is Not Just Tech CEOs


Yes, the top three are all from tech. But look further down the rankings and the picture gets more interesting. Scott Kirby (United Airlines), Ed Bastian (Delta), Anthony Capuano (Marriott), and Geoff Martha (Medtronic) all appear in the top 25. You do not need to be running an AI company to build influence on LinkedIn. You just need to sound like a human being.


The CEOs performing well outside of tech share a common trait: they talk about things that matter beyond their own company. Industry trends, societal shifts, personal reflections. They post like leaders, not like brands.


What the Data Says About Content


Product launches crushed everything — averaging 5,586 likes per post and dominating the top 20 posts overall. When a CEO announces something new and puts their name behind it, people pay attention. This is the highest-leverage content type by a significant margin.


Strategic vision posts came second. These are posts where a CEO shares how they see the world, not what their company did last quarter. Dimon's top post is the perfect example. People want to know what leaders think.


Conference selfies are dead air. "Great to be at Davos" was the most common content category among top CEOs and one of the lowest for engagement. Events and speaking engagements generate volume but almost no meaningful response.


ESG posts performed even worse — the only category where top CEOs received less engagement than the average CEO. Whatever your position on ESG, LinkedIn audiences are not responding to it.


Employee recognition, while well-meaning, barely moves the needle. A nice gesture internally, but it is not what builds executive influence.


The Playbook


If you are the person responsible for your CEO's LinkedIn presence, here is what the data says you should be pushing for.


  1. Post less, but make it count. The median top-25 CEO posted fewer than twice a month. Focus energy on fewer, higher-quality posts rather than maintaining a content calendar for its own sake.
  2. Lead with substance. Product launches and strategic vision posts outperform everything else by a wide margin. If your CEO is launching something or has a genuine perspective on where things are heading, that is the post to prioritise.
  3. Sound human. The CEOs winning here are sharing personal stories and worldviews, not corporate announcements. If it reads like it was approved by three layers of comms review, it will perform like it.
  4. Skip the panel photo. Conference content and generic industry appearances are the lowest-performing categories in the dataset. Save the selfie, write something with a point of view instead.
