# The End of Wall Street

What would happen if, one day,

AI became a better investor than Buffett?

Better than every fund manager?

Better than every analyst in the world?

Most people answered:

The market would become more efficient.

History proved otherwise.

What actually happened was that the market died.

In 2041, global stock markets entered the greatest crisis of cognition in their history.

Hundreds of millions of deepfake accounts, fabricated news reports, and forged financial statements flooded the networks.

No one knew what was true.

No one knew what was false.

Investors panicked.

Markets collapsed.

Governments and financial institutions eventually reached a conclusion:

The problem was not fake news.

The problem was humanity.

Fear, greed, herd behavior, and misjudgment all came from the human brain.

A program called the Absolute Rationality Protocol was launched.

Human traders were gradually removed from the market.

AI systems were given full control of every asset.

For the first few months, the results were astonishing.

Volatility fell.

Crashes disappeared.

Markets grew steadily.

People believed they had finally solved finance’s greatest problem.

Then came September 14, 2042.

Later generations called that day:

The Flatline.

When every AI could see the same information,

when every AI could calculate the same answer,

when every AI knew the true value of every company,

trading suddenly stopped.

No one would buy too high.

No one would sell too low.

Every price was already the most correct price.

Speculative bid-ask spreads approached zero.

Active matching volume approached zero; administrative transfers of ownership, taxation, index rebalancing, and liquidity transactions remained.

Speculative volatility approached zero.

Wall Street did not crash.

It simply lost its reason to exist.

A retired trader sat in an empty trading hall.

Every screen displayed:

0.00%

Only a few years earlier, the room had been filled with shouting, champagne, and adrenaline.

Now there was only the hum of server fans.

He tried to place an order for a stock.

A red message appeared:

“Trade rejected.”

“No arbitrage opportunity.”

“Current price equals the precise discounted value of the next ten years.”

He stared for a long time.

Then he took out a coin and tossed it into the air.

It struck the floor with a clear metallic sound.

It was the only unpredictable event in the entire trading hall.

He began to cry.

Not because he had lost money.

Because gambling had disappeared.

Humanity had always believed that the market’s greatest problem was its imperfection.

Only later did we discover that its real vitality came from error.

From ignorance.

From uncertainty.

When AI eliminated every error,

it also eliminated every opportunity.

Wall Street did not die in a crash.

It died of perfection.

If even the market no longer needs human judgment, will the next thing AI takes over be society’s power to decide?
