Let’s say you’re handed a puzzle box with millions of tiny, shifting pieces. Some are labeled “market trends,” others “human psychology,” and a few just scream “chaos.” For decades, Wall Street’s sharpest minds tried to solve this puzzle using financial theory, gut instincts, and spreadsheets thicker than a phonebook. Then came Feng Ji, a computer scientist with no finance background, who looked at the box and said, “Why not teach it to solve itself?”

| The Algorithmic Takeover: Why Traditional Quant Funds Face Extinction |
Feng’s company, Baiont, isn’t your typical hedge fund. Imagine a team of 30 people - mostly twentysomethings with gold medals from coding competitions - managing $970 million without ever touching a stock report . They don’t care about quarterly earnings calls, CEO resignations, or whether Elon Musk tweets about dogecoin at 3 a.m. Instead, they’ve built an AI that treats financial markets like a giant game of whack-a-mole : predict where prices pop up next, then strike. Fast.
Here’s the kicker: Feng’s team didn’t learn to trade by studying candlestick charts or reading Warren Buffett quotes. They learned by teaching machines to read. Not books, but the hidden language of markets - millions of data points flashing by every second, from order flows to micro-movements in stock prices. Their AI, like a hyper-focused student, isn’t distracted by news headlines or economic theories. It’s just looking for patterns, like a kid spotting shapes in cloud formations.
Traditional quant funds, Feng argues, are stuck in the Stone Age. They split trading into silos - someone hunts for “factors” (like “stocks rise when interest rates fall”), another builds models, a third executes trades. It’s like hiring a chef, a sommelier, and a food critic to cook a meal without ever letting them taste the ingredients. Baiont’s AI, by contrast, does everything at once. It’s the culinary school grad who masters knife skills, plating, and wine pairings in one go.
And why not? After all, predicting stock prices isn’t that different from predicting the next word in a sentence. ChatGPT’s magic lies in analyzing trillions of text snippets to guess what comes next. Baiont’s AI analyzes trillions of market transactions to do the same. The difference? If ChatGPT messes up, you get a nonsensical paragraph. If Baiont messes up, someone loses a yacht.
But here’s where it gets wild: Feng’s team isn’t even trying to “understand” finance. They’re treating markets like raw data - a bunch of numbers dancing to their own algorithmic rhythm. It’s like teaching a parrot to win a debate. The parrot doesn’t know what the words mean, but it’s memorized every possible argument.

Aha #1: The Future of Finance Isn’t Human
When Feng says traditional quant managers have three years to live, he’s not being dramatic. He’s just seen the math. Hiring 50 analysts to find market signals costs millions. Training an AI to do the same job with one programmer and 100 GPUs? Cheaper, faster, and less prone to ego-driven disasters. Think of it like replacing a room of typists with a single AI-powered voice-to-text tool. Why hire a team when one machine can outpace them all?
The Nerds Who Stole Wall Street
Let’s rewind to 2013, when China’s first wave of quant traders arrived. They were like financial Indiana Joneses - returning from Wall Street with leather satchels full of secrets. But Feng’s generation? They’re more like Silicon Valley’s Avengers. His team’s LinkedIn profiles read like a who’s-who of coding olympiads: 13 gold medalists among 30 people. That’s a nerd density higher than a NASA cleanroom.
These aren’t guys in suits scribbling formulas on whiteboards. They’re hoodie-clad coders who show up to work in shorts and slippers, debating neural networks over instant noodles. Their office vibe? A cross between a research lab and a startup incubator. And their secret weapon? Time .
No, not the abstract concept. Literal nanoseconds.
In the quant world, speed is currency. While Meta engineers stress over making Instagram load 10 milliseconds faster, Feng’s team measures performance in microseconds. To them, a millisecond is a geological epoch. They’ve optimized their systems so much that DeepSeek, a rival AI startup, spun out of a quant firm - because the same tricks that let you trade stocks in microseconds also let you train LLMs faster. It’s like realizing the engine you built for a go-kart can power a rocket ship.
But why would mathletes and AI wizards ditch Silicon Valley’s billion-dollar unicorns to play the stock market? Feng’s answer is brutally honest: “Most AI startups aren’t revolutionary. They’re just fancy tools.” Quant trading, though? It’s a blank canvas. A place where building a better algorithm doesn’t just improve a product - it rewrites the rules .
And here’s the twist: They’re not even playing the long game. While traditional investors obsess over “fundamentals” (like a company’s earnings or debt), Baiont’s AI focuses on the next five minutes. It’s like predicting the weather minute-by-minute instead of seasons. You might not know if it’ll rain next month, but you can bet your umbrella it’ll drizzle in 300 seconds.
Aha #2: Disruption Isn’t a Buzzword - It’s a Math Problem
Feng’s team isn’t disrupting finance because they’re rebels. They’re doing it because the numbers demanded it. When you can test 1,000 trading strategies in a day - instead of waiting months for quarterly reports - the feedback loop becomes instant. It’s the difference between tuning a piano note-by-note versus slamming the whole keyboard and instantly knowing which chord worked.
So where’s this all heading? Feng’s mid-term goal is simple: build a globally dominant AI-driven fund that makes Wall Street’s old guard look like VHS tapes. Long-term? He wants to start a tech company. Because once you’ve trained AI to beat markets, why stop there? The same algorithms could revolutionize logistics, climate modeling, even healthcare.
The moral of the story? The next financial crisis might not be caused by greedy bankers or subprime mortgages. It might be triggered by a 24-year-old in Hangzhou, sipping bubble tea and tweaking an algorithm that just figured out how to make a 0.0001% profit on every trade. Multiply that by trillions, and suddenly you’re not just running a hedge fund - you’re rewriting how money works.

| Machine Minds, Market Wins: The Rise of AI Trading Dominance |
How Baiont, a Chinese hedge fund founded by computer scientist Feng Ji, leverages artificial intelligence to disrupt quantitative trading. By treating financial markets as a pure machine-learning problem, the firm’s team of elite coders - without formal finance training - has achieved unprecedented success, managing $970 million with a 30-person team. The examines their holistic AI-driven approach, contrasts it with traditional quant methods, and highlights their prediction that firms failing to adopt AI will vanish within three years. It also delves into the broader implications of AI in finance, including the rise of nanosecond trading speeds and the migration of top technical talent to quant trading.
