XTX Markets Contributes Over £500m in Corporation Tax to UK Treasury
London-based algorithmic trading powerhouse XTX Markets, under the leadership of billionaire founder Alex Gerko, was liable for a corporation tax payment surpassing £500m in the 2025 fiscal year, according to a detailed analysis of corporate filings. The firm's latest accounts indicate that this substantial contribution positions XTX as one of the most significant individual taxpayers to the UK exchequer.
Tax Bill Soars Amidst Profit Surge
Based in Kings Cross, XTX Markets was due to remit approximately £580m in corporation tax for 2025, as per a City AM examination of official documents. This figure represents an increase of more than one-third compared to the previous year, driven by a notable surge in the company's profitability. The UK government reported total onshore corporation tax receipts of £89.2bn for the 2025 tax year, according to data from HM Revenue and Customs. Consequently, XTX's payment alone accounts for roughly 0.7 per cent of all corporation tax collected across the nation, despite the firm employing fewer than 200 full-time staff members.
To put this into perspective, XTX's tax payments would be sufficient to cover an entire day of operational costs for the National Health Service, which amounts to around £520m daily. This remarkable tax obligation follows a period of exceptional growth for XTX, which reported a 44 per cent jump in revenue to just under £4bn, with profits rising by a third to £1.7bn.
Innovative Trading and Market Volatility
Founded by Alex Gerko in 2015, XTX Markets utilises advanced machine learning algorithms to forecast prices across a diverse range of asset classes and financial instruments. The company has been a major beneficiary of the heightened volatility observed in global financial markets over the past year. To analyse vast quantities of market data, XTX employs tens of thousands of graphics processing units (GPUs), and is believed to operate one of the largest clusters of high-end Nvidia chips worldwide.
In recognition of its innovative approach, XTX has been named as a finalist in the 2026 City AM awards, specifically shortlisted in the category of most innovative company of the year. Alex Gerko, a Russian-born trader who renounced his citizenship in 2022, has cultivated a notable following within the City of London, largely due to his candid and often acerbic commentary shared on LinkedIn. In a post from February, he remarked, "Living in [the] UK [the] last 2.5 years is a radicalising experience."
Philanthropic Endeavours and Charitable Contributions
Beyond its substantial tax contributions, XTX Markets stands out as one of the United Kingdom's most generous charitable donors. In 2025, the company committed more than £150m to various charities and philanthropic causes. XTX has stated that its "philanthropic focus is on maths education and research, with an aim to support more students to progress to degrees and PhDs, and to accelerate breakthrough discoveries, particularly in pure maths and artificial intelligence."
The combination of significant tax payments and extensive charitable donations underscores XTX Markets' impactful presence in both the financial and social spheres, highlighting its role as a key player in London's dynamic trading landscape.
