The Math Whiz Who Quietly Built a $20B AI Trading Empire

What if I told you that a mathematician with a PhD in commutative algebra—a field so abstract it makes calculus look like finger painting—is now one of Britain's richest people? Meet Alex Gertco. At 46, he's just been ranked 8th on The Sunday Times UK Rich List with a fortune of £1.6 billion (about ¥14.17 billion). That's a jaw-dropping jump of £726.1 million in a single year. To put it in perspective, his wealth grew by roughly £19.89 million every day. Yes, every single day.

From Moscow to Mayfair

Born in Moscow in 1979, Gertco earned his math doctorate from Moscow State University, then picked up a master's in economics. He cut his teeth in quantitative trading at Deutsche Bank and GSA Capital before founding XTX Markets in 2015. But this isn't your typical Wall Street story. XTX has no external investors, no flashy trading floor, and—here's the kicker—no human traders. Just 250 employees and a relentless army of algorithms.

The Machine That Never Sleeps

So how does a company with fewer people than a small high school become a market-making giant? XTX's AI systems chew through over 400 petabytes of global financial data—that's roughly 400 million gigabytes—using massive GPU clusters. The algorithms analyze real-time orders from more than 50,000 financial instruments across stocks, bonds, forex, commodities, and even cryptocurrencies. They spot cross-market price patterns and execute trades in milliseconds. The result? A daily trading volume of $250 billion. That's more than the GDP of Finland. Every day.

The Man Behind the Curtain

Gertco owns 75% of XTX, and his wealth surge comes almost entirely from the company's soaring valuation. But he's not just a money-making machine. He founded Axiom Maths and the AIMO Prize, pouring resources into math education and AI research. He's also been repeatedly listed among the UK's top taxpayers—a rare badge of honor for a billionaire. While others dodge taxes, Gertco writes big checks. Make of that what you will.

What This Means for the Rest of Us

Gertco's rise isn't just a personal triumph; it's a flashing neon sign that AI and quantitative finance are merging into a commercial superpower. As data, computing power, and models keep improving, AI's role in pricing, liquidity, and strategy optimization will only grow. But let's not get carried away. Returns still depend on model performance, risk control, and—surprise—market conditions. AI isn't a magic wand; it's a very fast, very smart tool. And Gertco? He's the guy who figured out how to wield it better than almost anyone else.
