The story of how Deutsche Bank became a trading powerhouse around the world, from XTX Markets
Gerko has first developed his experience with traditional financial institutions before becoming a billionaire entrepreneur.
Career Timeline
| Year | Milestone |
|---|---|
| 2004 | Joined Deutsche Bank in stocks trading position |
| 2004-2009 | Started trading in foreign exchange |
| 2009-2015 | Head of Market-Making Team at GSA Capital |
| 2015 January | XTX Markets is established |
Gerko joined GSA Capital where he managed market-making activities and continued to gain insights into quantitative trading. He, however, thought the traditional trading model could be greatly improved by the use of advanced mathematics and machine learning.
This vision is the driving force behind the inception of XTX Markets in January 2015.
The firm’s name is an allusion to linear regression, a widely used statistical and predictive modeling method. This just shows that Gerko thinks the name of the game is trading based on data, models and scientific analysis, not on intuition.
Today Gerko owns about 75% of XTX Markets and he’s the big beneficiary of an incredible growth story.
In 2026, XTX Markets will be known for its AI-driven global trading capabilities
In 2026, XTX Markets is one of the most successful private financial firms in the world.
XTX, which does not rely on HFT to the same degree, is looking to leverage AI, machine learning and predictive analytics to enhance the trading decision making process.
Gerko has, on many occasions, ripped into the “zero-sum speed race” of traditional high-frequency trading, and even has recommended “market speed bumps” to lessen the impact of ultra-fast traders.
2025 Financial Performance
| Metric | Result |
|---|---|
| Revenue | £3.9 billion ($5.2 billion) |
| Profit | £1.71 billion ($2.3 billion) |
| Profit Growth | 33% increase |
| Dividend Paid | £1.8 billion |
| Volume of transactions | $250 billion daily |
| Instruments Traded | 50,000+ |
| Employees | Approximately 250 |
The numbers are astounding, given that XTX has about 250 staff, and is one of the most profitable financial companies per employee.
The use of AI infrastructure and the emergence of a new “arms race” in trading
One of Gerko’s greatest strategy wins is that he doesn’t completely trust cloud providers and has an interest in his own computing infrastructure.
Major Infrastructure Projects
XTX is opening operations at a $1+ billion data centre complex in Finland in 2026. The facility will be constructed to meet the AI demands of the firm.
Additional infrastructure includes:
- Iceland’s supercomputer
- Geothermal-powered computing systems
- Proprietary AI Model Training Environments
- Research facilities on a large scale, quantitative
By doing this, XTX is able to train machine-learning models more cheaply and more securely than their rivals, who rely on rented cloud computing resources.
The outcome is a new competition between financial companies to be smarter, not just faster.
In response, companies like Jane Street have poured significant money into AI hardware, for example a $1 billion investment in CoreWeave.

Gerko has become one of the richest persons in Europe thanks to his financial achievements.
Net Worth Estimates (2026)
| Source | Estimated Wealth |

| Mark Zuckerberg and Priscilla Chan had the largest increase in the Bloomberg Billionaires Index | $17.1 billion |
| Forbes (2025) | $13.2 billion |
| The Sunday Times Rich List 2025 (UK) | £8.7 billion |
The lion’s share of his fortune comes from his stake in the company XTX Markets.
Gerko is also famous for his considerable tax payments. In recent years he has been regularly among the biggest taxpayers in Britain. Analysts believe that, based on his recent financial performance, he could be the UK’s top individual taxpayer once again.
He has also dropped his Russian citizenship, and made Britain his new home, which further boosts his public profile in the UK.
Education and Scientific Research, Philanthropy
Gerko is known for his many financial successes, and he is also an active philanthropist.
Major Philanthropic Contributions
XTX Markets has donated a total of around $464 million (£350 million) to charitable organizations and nonprofit initiatives since 2020.
Key projects include:
Global Talent Fund
Gerko contributed $40 million in April 2026 to create the world’s largest scholarship program for talented young mathematicians and scientists.
The program is designed to provide support to about 150 outstanding students, enabling them to continue their education in STEM.
Numeracy and Mathematics Education
Gerko supports initiatives throughout the schools of Britain to raise maths literacy and inspire students with the talent to embark on science and technology careers.
Argus Array Astronomy Project
His most ambitious scientific investment is the Argus Array, which he created in collaboration with UNC-Chapel Hill and Schmidt Sciences.
The telescope system will:
- Look at all parts of the Northern sky at once
- Real-time detection of supernovae
- Keep track of neutron star mergers
- Advance astronomical discovery
The construction is underway and scientists say it could greatly boost human knowledge about the universe.
Legal Discourse, Investments, and Wider influence
Gerko and 12 former GSA Capital traders challenged about £22.5 million ($30 million) in taxes for deferred trading profits in June 2025.
The controversy stemmed from lower-court decisions that used the individual tax rates instead of the corporate tax rates. This case got a lot of media coverage and was a subject of discussion about tax policy and financial regulation.
In addition to XTX Markets, Gerko is also an active angel investor.
Investment Portfolio
- 64 investments
- 18 active portfolio companies
Notable investments include:
- Boom Supersonic (aerospace innovation)
- Fotokite (hardware technology)
- Compology (Waste management solutions with AI)
- Yet Analytics
His investment approach has always been geared towards science, technology and businesses that are based on innovation.
