The AI Traders: Inside Wall Street’s Algorithmic Revolution

Special Report: How Artificial Intelligence is Reshaping Finance

By Anthony O’Connell WIRED | May 2024

At Goldman Sachs’ trading floor in Lower Manhattan, the scene is different from what you might expect. Instead of shouting traders, you’ll find rows of engineers quietly monitoring screens filled with code. Welcome to modern Wall Street, where AI systems now handle 60% of all U.S. equity trading volume.

“The human trader isn’t extinct,” explains David Solomon, Goldman’s CEO. “But their role has fundamentally changed. They’re now AI supervisors rather than direct market participants.”

THE NEW MASTERS

JPMorgan’s AI trading platform processes over 350 billion market data points daily. Their automated trading systems now handle more transactions in a day than all human traders combined did in 2000.

“Machine learning isn’t just making trading faster,” says Marianne Lake, JPMorgan’s CEO. “It’s discovering patterns humans never could have seen.”

BLACKROCK’S BRAIN

Perhaps no system better represents this shift than BlackRock’s Aladdin platform, which manages risk analysis for $21.6 trillion in assets worldwide. That’s more than the GDP of the United States.

“Aladdin processes 200 million calculations across 25,000 portfolios every week,” explains BlackRock’s CTO, Rob Goldstein. “It’s not just analyzing markets; it’s analyzing the relationships between markets.”

THE SPEED GAME

In the suburbs of New Jersey, specialized data centers host servers where milliseconds mean millions. Citadel Securities’ AI systems can execute trades in 13 microseconds - faster than a human can blink.

“The speed race is over,” says Citadel’s Ken Griffin. “Now it’s about who has the smartest algorithms, not just the fastest ones.”

RENAISSANCE’S SECRET

Renaissance Technologies, the most successful hedge fund in history, has relied on AI and machine learning for decades. Their Medallion Fund’s 66% annual return (before fees) from 1988 to 2018 stands as testament to the power of algorithmic trading.

THE WATCHDOGS

The SEC has responded by developing its own AI tools. “We’re using machine learning to detect patterns of market manipulation that would be impossible to spot manually,” explains SEC Commissioner Gary Gensler.

MAIN STREET IMPACT

These changes aren’t limited to Wall Street. Retail investing platforms like Robinhood use AI to:

• Detect fraud
• Optimize order routing
• Provide automated customer service
• Analyze investment patterns

THE HUMAN ELEMENT

Despite the AI revolution, human judgment remains crucial. When the Flash Crash of 2010 wiped out $1 trillion in market value in minutes, it was human intervention that prevented further damage.

“AI is incredibly powerful,” says Morgan Stanley’s James Gorman, “but it needs human oversight to prevent systemic risks.”

LOOKING AHEAD

The next frontier isn’t just faster trading - it’s smarter trading. Goldman Sachs is developing AI systems that can:

• Analyze satellite imagery for economic insights
• Process natural language from earnings calls
• Model complex market relationships
• Predict market reactions to global events

THE BIGGER PICTURE

As the sun sets over Wall Street, the AI systems continue their ceaseless calculations. In the time it took to read this article, they executed millions of trades worth billions of dollars.

“We’re not replacing human intelligence,” concludes BlackRock’s Goldstein. “We’re augmenting it. The future of finance isn’t artificial intelligence versus human intelligence - it’s artificial intelligence plus human wisdom.”
