The global market turmoil not only failed to harm the UK-based high-frequency trading firm XTX Markets, but instead became the best catalyst for it to set a new record.

According to filings with Companies House, XTX's UK entities reported after-tax profits of £1.7 billion in 2025, a 33% increase year-on-year; revenue grew 44% to £3.9 billion, compared to £2.7 billion in the same period last year. This achievement places XTX among the most profitable private companies in the UK.

XTX's strong performance aligns perfectly with the backdrop of global market volatility caused by US President Trump's unpredictable tariff policies and the far-reaching impact of artificial intelligence—the more volatile the market, the more useful its algorithmic system for capturing price anomalies becomes.

Russian-born mathematician and XTX founder Alex Gerko owns approximately 75% of the company's shares.

As previously reported by Wall Street Insights, in London's forex industry, no high-frequency trading firm has started and grown as rapidly as XTX Markets. Alex Gerko amassed a fortune of $11 billion in less than 10 years, becoming the UK's top taxpayer.

Algorithm-driven, daily trading volume reaches $250 billion

Headquartered near King's Cross in London, XTX was founded in 2015. Its core competency lies in using machine learning and artificial intelligence to identify and trade price patterns and anomalies in the forex, stock, bond, commodity, and cryptocurrency markets.

The company stated that its daily trading volume in global markets is approximately $250 billion.

XTX's main competitors include Ken Griffin's Citadel Securities, which also offers trading services, but XTX is relatively small with about 250 employees.

Despite being smaller than its competitors, XTX maintains a significant advantage in profitability and efficiency thanks to its highly automated operating model, and its continuous growth trajectory has never been interrupted since its inception.

Rapid wealth accumulation fuels space telescope project

As previously reported by Wall Street Insights, in London and in the foreign exchange sector, no high-frequency trading firm has started and grown as rapidly as XTX Markets. Nor has any Russian-born mathematician amassed a fortune of $11 billion in less than 10 years, becoming Britain's top taxpayer, like Alex Gerko.

As his wealth accumulated, Gerko established his personal family office in 2024, named Cromulon Capital—inspired by the human-shaped planet in the American science fiction comedy Rick and Morty.

This naming reflects Gerko's keen interest in science: he is currently funding the construction of a space telescope in Chile.

In the philanthropic field, XTX recently donated $40 million to the nonprofit Global Talent Fund to support 150 students in attending top universities, marking the company's largest single donation to date.

Venture Capital Landscape: 35 AI Startups

XTX is also active in early-stage venture capital. According to its official website, the company has invested in at least 35 startups focused on artificial intelligence, covering healthcare, software, and other industries.

Specific investment targets include autonomous driving company Wayve, semiconductor startup Groq, and AI voice company Voiceitt.

This investment strategy aligns with XTX's core business logic of AI and machine learning, and also demonstrates Gerko's strategic intention to extend its technological advantages from the trading field to a broader technology ecosystem.
