Last Sunday, a researcher and fellow Substack writer Citrini posted a question on X. It began in the future tense: June 2028. The S&P had plunged 38% from its peak. Unemployment clocked in at 10.2%. AI had not only met expectations, it had shattered them.
What happened?
The thread linked to a full article. Twelve thousand words of speculative macro fiction of AI agents replacing half the white-collar workforce, private credit unraveling, prime mortgages cracking in tech hubs, a deflationary spiral caused by how good the technology is by wiping out need for a bunch of excess labor.
It was a thought exercise, from the future. Citrini said.
Twenty-one million people read the post, and forty-four thousand bookmarked it. Investors around the world copy and paste the post into their own corporate-sponsored ChatGPT and ask: Stress test my positions against this thesis, assuming it’s ALL TRUE. Make no mistakes.
When markets opened Monday morning, DoorDash tumbled 8%. American Express followed suit. Apollo, Blackstone, Visa, Mastercard, ServiceNow. Every company named in the thought experiment was affected. The iShares software ETF hovered near a 52-week low, wiping out nearly all the gains since ChatGPT’s debut in November 2022. Three years of the AI trade, erased before lunch. Bloomberg and The Wall Street Journal both ran with the story, pinning the selloff on a Substack post. All this, triggered by a piece of fiction, openly labeled as such, penned by a researcher unknown to most of Wall Street.
Ten months earlier. An account called Walter Bloomberg (not affiliated with Bloomberg), just a dude with a blue checkmark and a propensity of posting headlines in all caps, writes: HASSETT: TRUMP IS CONSIDERING A 90-DAY PAUSE IN TARIFFS FOR ALL COUNTRIES EXCEPT CHINA.
It was fake news. But the headline had already escaped. CNBC read it live and Reuters published it. In just ten minutes, the S&P soared 8%. Two point four trillion dollars moved. The White House made its disclaimer and Walter Bloomberg deleted the post.
Two days later, Trump actually paused the tariffs for ninety days, exactly as the fake headline had described. But hours before announcing the real pause , the one that would add four trillion dollars back to the market, he posted on Truth Social, also in all caps: THIS IS A GREAT TIME TO BUY!!! DJT.
And then October. A single Truth Social post, “massive increase” in tariffs on China, erased more than hundreds of billions from U.S. semi stocks market cap in a day. Trade deals were announced, tweaked, scrapped, and revived, all through social media, all at the speed of a keystroke, long before the machinery of government could even open a Word document to draft a response.
What once demanded a Soros is now open to any theorycel with a Substack. A researcher posts a scenario and the scenario shapes the sector, at least the perception of it. A blue checkmark posts a headline and the headline becomes policy. Soros’ reflexive loop is now compressed, democratized, stripped of the institutional drag that once gave people time to think. We’ve evolved past his framework. The loop no longer needs to be understood to work. It no longer requires meaning. It only needs motion.
This is headline economics, and its logic recursive.
The Carcass
Yorgos Lanthimos’s new film Bugonia tells the story of a kidnapping that also serves as a test of what we know and believe. A man kidnaps a female CEO because he thinks her company is killing the bees and his mother, and that she is an alien following orders from an emperor in Andromeda. He turns out to be right about everything. Still, Lanthimos, who might be the cruelest filmmaker working today, makes sure that this truth does not change anything.
The conspiracy theorist has the facts. His accuracy is beside the point. What his pain requires is not truth, but a container: a villain, a structure, an address to which suffering can be sent. Without one, pain is ambient and therefore permanent. Conspiracy theory is compensatory agency, by restoring a sense of participation in a system that has locked one out of every lever.
Emma Stone, the CEO, inhabits the opposite epistemology. She doesn’t need to make up any new story but simply exist in the perpetuating logic of capitalism. “My company is a key job creator and economic engine of the region. I am important,” she said with sincerity. There’s no irony because her claim is coherent to her worldview. She can’t see what he sees, because her instruments were calibrated for a different set of heuristics entirely.
The film’s title comes from Virgil. Bugonia is the old belief that bees are born from the body of a sacrificed ox. It is the idea of life coming from decay, sweetness from death. In truth, what actually came out of the ox were drone flies, colored black and gold, fast enough to look like honey bees. People want to believe so badly, because facing the truth (that the ox died for nothing, that sweetness will never come, that decay is just decay) is uncomfortable.
Which is to say, people see what their position requires. And in America, position has split clean in two. The K-shaped split in the economy doesn’t just bifurcate economic outcomes, but perpetuate different narratives people tell themselves. The needs from either end are so different that they create worldviews that can’t be reconciled, each making sense on its own but impossible for the other side to see.
The conspiracy theorist’s paranoia creates a villain and a story that keeps his fears going. The executive’s power creates the incentives that support her position. The contrast between these two ways of thinkings represent a defining characteristics of markets.
Soros came close to describing this through his seminal work in Reflexivity, and Schiller’s narrative economics brought us even closer. And neither fully captured what happens once latency tends to zero. Soros’s reflexive loop implies that the cognitive function has time to update when presented net new information. And Schiller’s narratives spread like epidemics, which require time for incubation. In headline economics, contagion detonates everywhere all at once. Reflexivity arrives as an explosion before we have time to understand what’s going on.
When latency approaches zero
In Narrative Economics, Shiller argued that stories spread like epidemics and move markets the way viruses move through populations. The dotcom boom, the subprime bubble, crypto. Narratives helped create these bubbles. They shaped economic behavior, making people buy, panic, or hold out based on stories rather than clear reasoning.
Shiller’s narratives spread only as fast as people could talk. Dinner parties, newspaper columns, a coworker mentioning his brother-in-law who made money flipping houses in Phoenix. The housing story played out over ten years, slowly unraveling, as documented in The Big Short. Bitcoin took years, too. People had time to think about information and decide what to do, which now feels almost quaint.
The American lawmaking system was an additional buffer, giving markets time to determine prices. Policy went through hearings, markups, long stretches of floor votes. Markets could process these signals, but there were still physical limits that required people to work together. Now, the policy (or potential policy) shows up as a short, capitalized message on the screen. The gap between when something happens and when it is verified has widened. Policies don’t have to go through the bureaucracy to become a signal.
The headline describes what happened and simultaneously becomes the event itself.
This is what headline economics shows: markets trade based on how easily a claim can be turned into a position, how clear its direction is, and how widely it spreads. Tradability is the main feature. What matters most is whether the headline’s effect on price is big enough to turn voluntary trades into forced ones. Once the price crosses a certain threshold, algorithms take over. In a zero-latency market, forced liquidations happen first. The basic reality of an event now matters less than its second derivative: the fast-moving momentum of structural capitulation.
Citrini’s story became powerful because it was so easy to understand. It did not rely on vague fear, but clearly named the casualties, removing the need for interpretation by serving ready-made pair trades on a plate. One doesn’t need to ask if something is real, but whether they can act on the incoming momentum before someone else does.
Soros called this reflexivity, meaning the market watches itself and changes what it sees in the process. The market does not just reflect reality; it rewrites the story as it goes, like a marriage that changes through the acts of faith or a child who behaves differently when being watched by their parents.
Stripped of context and propagated at network speed, the headline is now a unit of economic reality, among many. Its fragmentation and speed grant it power through algorithms, allowing it to travel faster than verification.
The bruise and the flinch
At the start of Bugonia, you already sense Teddy’s tension even before you know why. You see it in Plemons’s posture as he rides the bus to his warehouse job at Auxolith, clocking in for a company he’s secretly working against. Emma Stone’s CEO is simply the face of his fantasy.
The Citrini post didn’t move billions because it offered any groundbreaking insight. In fact, most fund managers had already imagined this scenario, likely during late nights spent worrying about their worst fears. The thought that AI could succeed but still lead to disaster was already on their minds, lingering in their portfolios and sleepless pre-market hours, waiting for something to make it real. Citrini did that.
You can’t trade on a feeling of vague dread. But once that fear becomes clear, it can move markets. The post simply set up a tension that’s already there.
A tense market is a supersaturated solution. It has already absorbed more than it can hold; it’s just waiting for the grain. That’s all a headline is, on the days it matters, and most days it doesn’t, most days it’s a stone in still water. It presses where it hurts, and the flinch tells you how deep the bruise goes.
Although a headline can push prices out of line, but the dislocation rarely lasts. The S&P bottomed in March 2020 and was back at pre-pandemic levels within months even before the vaccines and reopening. The tariff scares resolved the same way, where in a few weeks, the price found its way back to its value. This is usually told as a story about resilience, but recovery is not the same as restoration. Something gets spent in the round trip, and what gets broken doesn’t show up in the index.
In a leveraged market, just twelve minutes of incorrect prices can cause lasting harm. Stop-loss orders triggered during Walter Bloomberg’s twelve minutes led to real losses based on a signal that never existed. A margin call caused by false information does not get undone when the truth comes out. The retail investor who sold her 401(k) near the bottom, unable to watch her balance drop any further, was already out by the time the market rebounded in August. She missed the recovery. The Salesforce product manager who lost her $180,000-a-year job during the panic will not get a call back when things calm down and the index turns green again. Now, she drives for Uber.
The price recovered, but her life did not.
K-shaped economy and K-shaped perception
The damage does not fall equally.
In what’s called a K-shaped economy, the bottom half of Americans—about 165 million people—own just 2.5% of the nation’s wealth. Meanwhile, the top 10% controls 87% of the stock market. Since ChatGPT came out, AI stocks have made up three quarters of the S&P’s returns. When people talk about the economy’s performance, it’s really just a small group benefiting while most of the country is left out.
The fund manager who sells ServiceNow in a panic on Monday morning is the same one who buys Micron later that day. The Citrini post was negative about software and payments, but extremely optimistic about AI infrastructure—if you could read it that way.
At the top of the K, where people have the power to move markets, even reading a headline is like making a trade. The Citrini post sparks fear, which leads to selling. That selling becomes a Bloomberg headline, which causes even more fear and more selling. Thinking and acting happen almost at the same time. Portfolios are rebalanced before the second cup of coffee is finished.
At the bottom of the K, all you can do is think and worry. You read the same post and feel the same dread. Maybe you’re a Salesforce product manager making $180k who gets laid off and ends up driving Uber for $45k. Maybe you’re a 760-FICO borrower in SF who did everything right and are watching the ground shift under a mortgage that was good on the day it was written. You feel all of it. The emotional amplitude is identical to the fund manager’s. The economic amplitude is a rounding error.
You can’t make a move. Your RSUs haven’t vested, or they’re so far underwater that you feel stuck. You can’t hedge your bets. You can’t short the stocks you know are in trouble. You can’t switch into Micron because you don’t even own it. What you do have is a mortgage. Your fear has nowhere to go except sharing the post, bookmarking it, arguing online, or texting a friend, “we’re SO fucked!!!!”
We know that every compression of a reflexive cycle eventually forced something new. The South Sea Bubble created the first financial regulation. In 1929, the SEC, and in 08, Dodd-Frank. Each time, the cycle kept spinning until it broke; and then we rebuild.
Tomorrow morning, there will be another headline. Numbers move before the first sip of coffee; the dread gets a ticker and now a direction, and for a second that almost feels like relief, because at least now it has a name.
