Keith Gill: The Joker of Wall Street

The Gotham Files Part 1: Leadership Lessons from the Meme-Stock Revolution

Jun 13, 2025

Gotham sleeps uneasy.

Somewhere between midnight and dawn, under the weight of its own corruption, the city hums. The streetlights flicker as storms roll in from the bay. The skyscrapers stand tall, but the foundations are cracked. Bankers shuffle spreadsheets behind bulletproof glass. CEOs lie awake, clutching their stock options. Hedge funds whisper in dark boardrooms, plotting moves and countermoves like medieval kings. And in the shadows, something stirs.

This isn’t Gotham, of course. It’s Wall Street. Silicon Valley. The American financial machine. But for our story, the parallels hold.

Because every system, no matter how fortified, is vulnerable. And every so often, someone comes along who doesn't want to play by the rules. Someone who doesn’t just break the game, he rewrites it. Someone who doesn’t want the power, the glory, or the title… someone who just wants to watch the world burn in a very specific, highly strategic, and brilliantly calculated way.

Enter Keith Gill. Roaring Kitty; the Joker of modern finance.

He arrived like the Joker in The Dark Knight, seemingly out of nowhere, with no traditional résumé that justified the kind of power he would soon wield. A ghost. A question mark. And yet, by the time the dust settled, entire hedge funds would collapse. Billion-dollar firms would fold. Wall Street titans would sit helpless, as if tied to chairs in a warehouse, watching gasoline barrels drip while Roaring Kitty lit the match and smiled.

So who is this man? And why is he the closest thing we have to a real-world corporate Joker?

TL;DR:
Keith Gill, aka Roaring Kitty, became the Joker of Wall Street not because he craved chaos, but because he exposed just how fragile and rigged the system really was. He didn’t break the game with billions. He rewrote the rules with memes, conviction, and a legion of pissed-off retail traders. It wasn’t about money. It was about the message: that even the biggest financial mobs can bleed when the village fights back. This is a modern Gotham story and Roaring Kitty lit the match.
Sometimes leadership isn’t about status. It’s about strategy, timing, and refusing to play by broken rules.

🔥 The Spark

Before the world knew his name, Keith Gill was nobody. He wasn’t a hedge fund manager, or a Silicon Valley wunderkind, or a billionaire tech savant with a god complex. He was a dad from Massachusetts, sitting in a modest room with cat posters on the wall, breaking down stock plays on YouTube for a few dozen followers under the handle Roaring Kitty.

But like all great agents of chaos, he saw what the crime bosses didn’t.

To Wall Street (the Mob in this Gotham story) GameStop was a dead man walking. A bankrupt relic of a retail past they’d already looted. Investment bankers circled the stock like vultures, loading up on short positions so aggressively it bordered on financial overkill. They weren’t betting it would fail, they were ensuring it. Like mobsters leaning on a struggling shop owner, they borrowed shares they didn’t own, sold them into the market to drive down the price, and planned to buy them back cheap once the job was done.

In their world, that’s just how the game works.

But Gill saw what they didn’t. The arrogance. The sloppiness. The exposure. The mob had gotten fat, lazy, and overleveraged. They’d shorted more shares than actually existed. They assumed no one would notice, and even if someone did, what could they possibly do?

That’s where Joker stories always begin: when somebody finds the crack.

Gill didn’t invent short squeezes. He didn’t create a new model. What he did was something far more dangerous. He exposed the system’s weakness to the public. He weaponized awareness. He understood that if enough people bought into the stock, it would trigger a chain reaction. The mobsters would have to buy back what they had borrowed at any price, or risk financial ruin.

He wasn’t just playing a trade.
He was holding up a mirror.
And behind him, the streets of Gotham were watching.

The Weapon: Asymmetric Warfare

What made Keith Gill dangerous wasn’t that he had billions of dollars. He didn’t. It was that he understood the real currency of modern markets: attention.

Wall Street had Bloomberg terminals and predictive models.
Gill had cat memes and diamond hand emojis.
The hedge funds had risk officers and earnings reports.
Gill had Reddit.
The institutions had CNBC.
Gill had WallStreetBets, and it was about to become the Arkham Asylum of finance.

The Joker didn’t need a trained militia, he needed belief.
He needed the chaos already simmering beneath Gotham’s surface.
So he blew open the doors of Arkham, let the inmates out, and handed them a plan.

That’s exactly what Keith Gill did.

He didn’t build a rebellion from scratch. He found one already in progress. A generation locked out of wealth-building. Burned by 2008. Mocked for student debt. Nickel-and-dimed by institutions that preached free markets but moved the goalposts every time the house got threatened.

Gill didn’t teach these people how to trade. He gave them a cause.
And more importantly, he gave them a target.

GameStop wasn’t just a trade. It was a middle finger in stock form.
Buying it wasn’t just investing, it was rebellion.
It was your $600 stimulus check becoming a Molotov cocktail.

He lit the match, walked away calmly, and let the inmates of the system; the retail traders, day job warriors, basement analysts, take it from there. All it took was Reddit threads, absurd conviction, and free trading apps that let people turn emotion into action.

This wasn’t about logic. It was about game theory.

One player makes a move that the rest of the players aren’t prepared for. A move that exploits blind spots in their models, their psychology, and their assumptions. The mob thought they were betting against a company. Gill revealed they were actually betting against millions of pissed-off retail traders. Traders who didn’t care about price targets or fundamentals. They cared about revenge. About exposure. About proving that maybe the system was never fair to begin with.

In traditional finance, a single retail investor is a flea on an elephant.

But Gill made them swarm. And suddenly the elephant was bleeding from every direction. Confused, clumsy, and crashing into walls.

That’s how you beat Goliath when you don’t have a sword.
You don’t fight one-on-one. You invite the whole damn village. You rally the troops. “The British are coming! The British are coming!”

Wall Street called it a bubble.
Gill called it conviction.
The crowd called it history.

It wasn’t a trade. It wasn’t even a movement.

It was Arkham unleashed.

And the Joker wasn’t laughing at Gotham anymore.
He was laughing with it.

The Chaos Unleashed

By January 2021, Gotham was on fire.

The GameStop short squeeze had ignited into a full-blown financial inferno. Hedge funds were hemorrhaging cash. Melvin Capital, one of the cockiest short sellers in the game, lost over $6.5 billion, and had to be bailed out with $2.75 billion like a casino whale who’d just lost the house's money. GameStop’s stock price didn’t just rise, it detonated. From under $20 to nearly $500 in a matter of days.

And suddenly, the mob bosses weren’t laughing anymore.

The real Wall Street, the power players who had for decades operated like untouchable dons, were getting curb-stomped by a wave of pajama-clad Reddit degenerates with trading apps and meme-fueled rage.

It was like watching Maroni and Falcone realize someone had slipped explosives into their poker chips.

They weren’t fighting another mob.
They were fighting chaos.

The Media Machine Panics

Every Gotham needs its talking heads. The loud voices on TV who keep the public calm while the mob runs things in the shadows. In The Dark Knight, it’s the sleek anchors who carry Joker’s threats live on air, not realizing they’re part of the spectacle.

In 2021, that role belonged to the financial media. And boy, did they play it. In the first 3 weeks of the new Biden administration there were more news reports on GameStop than there were on the new president of the United States.

Jim Cramer. CNBC. Bloomberg. They couldn’t make sense of what was happening, but they were damn sure it shouldn’t be happening. These were the very same outlets that had spent decades cheerleading hedge funds, glorifying "activist investors," and clapping for every corporate raider who gutted a company for parts.

But when the mob got mobbed?
When the same tactics were turned back on them by unwashed retail rebels?

Suddenly, this was “market manipulation.”
Suddenly, this was “dangerous behavior.”
Suddenly, the game they built was too unpredictable.

It was like watching the Gotham Gazette try to smear Batman while the Joker broadcast live from a burning ferry.

Enter: Gotham PD (a.k.a. the SEC)

And where were the cops?

The SEC (our story’s Gotham PD) arrived late to the scene, sirens blaring, not because they were ready to stop the fire… but because they had no idea how it started.

They’d been asleep at the wheel, regulating yesterday’s market while tomorrow’s market was being rewritten in real time. The rules they enforced weren’t built for TikTok traders, Reddit raids, or the kinds of asymmetric momentum games Gill had uncorked.

They launched hearings. They asked questions. They wrote press releases.

But like Jim Gordon watching the Joker rewrite the rules in real time, the SEC had no playbook for a world where the inmates weren’t just running the asylum, they were day trading it on their lunch break.

The Mob Loses Its Mind

What enraged the hedge funds most wasn’t the loss of money. And they certainly lost a lot. Over $20 billion by the time the smoke settled. What enraged them was the loss of control.

For decades, they were the architects of this game: short a stock, publish a report, crush the price, profit. A rinse-repeat racket executed under the banner of “efficient markets.”

But when Keith Gill rallied a few million retail traders to turn the tables, to buy and hold no matter the price, the mob called foul. The rules had always been elastic when they bent them. Now that they were snapping the other way, they cried injustice.

Gill had done what the Joker always does:
Exposed the double standards.
Showed that the system wasn’t built on fairness. It was built on fragility.

The Message > The Money

At the height of the chaos, Gill’s portfolio ballooned into the tens of millions.

But he didn’t cash out.
He didn’t disappear to a yacht or a bunker.
He kept posting. He held the line.

Because for Gill, like Joker, the point wasn’t profit. It was the spectacle. The reveal. The message.

“It’s not about money. It’s about sending a message.”

A guy with no formal power, no institutional support, no capital behind him. Just game theory, Reddit memes, and moral fire. He had cracked open the system for the entire world to see.

He didn’t take over the mob.
He didn’t even want their throne.
He just wanted to show the people that the mob wasn’t invincible… and maybe never had been.

The Birth of Corporate Anarchy

In every Gotham story, Joker isn’t content with stealing from the mob. He wants to turn the mob against itself. He wants to watch powerful people scramble for control they no longer have.

That’s exactly what Gill achieved.

The hedge funds blamed the retail traders.
The retail traders blamed the hedge funds.
Robinhood fell on their sword and froze trades to protect liquidity. (More on this in part 3.)
Congress dragged everyone in for hearings.
The SEC opened investigations.

But at its core, none of them could explain how it had all slipped so far, so fast.

The answer was simple: the game had changed.

Keith Gill had weaponized game theory itself. He had created a situation where the collective behavior of millions of small actors could force the hands of the largest players. Not through collusion, but through the predictable mathematics of forced covering.

Every hedge fund model that assumed "retail traders are irrational" turned out to be correct, but irrelevant. Because irrational coordination is still coordination.

The Joker doesn’t play by your rules. He plays by showing you how fragile your rules are.

The Setup for Two-Face

And as the system convulsed, the door opened.

Because every time the Joker burns Gotham’s underworld, a new figure steps into the ashes. Someone who sees opportunity inside the chaos. Someone who flips the coin and plays both sides of order and disorder.

While the hedge funds burned and Reddit chanted, one man quietly began accumulating shares of GameStop. He didn’t livestream. He didn’t post memes. He didn’t rally a movement. He simply positioned himself to take control of the boardroom while the battlefield was still smoking.

His name was Ryan Cohen.

And if Keith Gill was the Joker of this story, Ryan Cohen was becoming Two-Face. The man who plays both chaos and control.
