Gary Stevenson: Trader Turned Wealth Tax Activist

There’s a reason people keep returning to the story of Gary Stevenson. The former Citigroup trader, who entered the London trading floor in 2008 at age 21, now spends his time arguing for a wealth tax.

Full name: Gary Walter Stevenson ·
Born: 1986 ·
Occupation: Former trader, YouTuber, author ·
Known for: Economic commentary, wealth tax activism ·
Notable work: The Trading Game (book)

Four key facts define Gary Stevenson’s public profile: his name, birth year, current occupation, and the reason he’s known.

How did Gary Stevenson become a millionaire?

Stevenson grew up in Ilford, east London, in a working-class family, according to The Guardian (UK newspaper). He studied mathematics and economics at the London School of Economics, a path that led him to a peculiar entry into finance: he won a card game used by Citibank to test aspiring traders, as reported by the Financial Times (business newspaper).

What did Gary Stevenson trade?

• He worked as an interest rates trader on the London desk of Citibank, trading derivatives tied to interest rates and foreign exchange (New Statesman (UK current affairs magazine)).
• His role involved betting on the direction of central bank rates, a high-stakes game that paid off massively during the post-2008 volatility.

His earnings progression, as reported by eFinancialCareers (finance industry careers site), tells a sharp story:

The implication: Stevenson’s wealth didn’t come from a single lucky bet but from a pattern of leveraged trading that he later argued creates systemic inequality. His exit from trading in the early 2010s—reportedly around 2012 per New Statesman or 2014 per Millionaires for Humanity—was driven by burnout, not a lack of talent.

How rich is Gary Stevenson?

Gary Stevenson net worth

Exact net worth figures are not publicly confirmed. During his trading peak, Stevenson earned over £1 million annually, but he left the industry before accumulating the kind of fortune seen by hedge fund managers. A 2026 profile in EL PAÍS English (international newspaper) notes that he reportedly told colleagues he was “Citibank’s most profitable trader in 2011” and that the bank made $35 million from his trading that year—a claim that appears on his Wikipedia page but is not independently verified.

How much did Gary Stevenson make?

• By age 24, he was earning more than £1 million per year (The Big Issue).
• His best reported personal income year was $2.5 million, per eFinancialCareers.
• He said in a Guardian interview that he made his first million within two years of starting. (The Guardian)

What this means for anyone researching Stevenson: the numbers are real but the context is everything. He was a highly paid employee, not an owner of capital—a distinction central to his political message.

What does Gary Stevenson do now?

What qualifications does Gary Stevenson have?

He holds a degree in mathematics and economics from the London School of Economics (Financial Times). His LSE education combined with his trading experience gave him the analytical tools to critique economic policy.

Gary Stevenson book

In 2024, Stevenson published The Trading Game: A Confession, a memoir of his time in finance. The book, reviewed by New Statesman, details his rise at Citibank and his growing unease with the ethics of high finance.

Gary Stevenson documentary

No documentary has been officially announced, but Stevenson’s story has been covered extensively by The Guardian and EL PAÍS, and his YouTube channel ‘Gary’s Economics’ serves as his primary platform. He has over 500,000 subscribers as of early 2026, though this number is not officially confirmed.

His current work includes: running the YouTube channel, campaigning for a wealth tax, and writing. He is a member of Millionaires for Humanity, a group of wealthy individuals who advocate for higher taxes on the rich (Millionaires for Humanity).

The pattern: Stevenson uses his finance background to explain complex economic concepts in accessible videos, often focusing on the wealth gap and the role of central banks. His book and media appearances have amplified his message beyond YouTube.

Who is Gary Stevenson’s wife?

Does Gary Stevenson have a partner?

Stevenson is married, but his wife’s name and background are not publicly disclosed. In a 2025 Guardian profile, he mentions a “beautiful girlfriend” during his trading years, but his current partner is not named in any major source.

How many children does Gary Stevenson have?

He has at least one child, but the exact number is not confirmed. A 2026 EL PAÍS article mentions he lives in London with his family, without specifying size.

What this means for privacy: Stevenson has chosen to keep his personal life largely out of the public eye, focusing media attention on his economic arguments rather than his family. This contrasts with his very public online presence.

What has happened to Gary Stevenson?

Gary Stevenson health

In July 2026, Stevenson announced he would be leaving his YouTube channel due to health reasons. The announcement was covered by The Guardian, which reported that he cited burnout and the toll of constant public engagement. This mirrors his earlier departure from trading, which he also attributed to physical and mental exhaustion.

Gary Stevenson to quit YouTube

According to the same Guardian report, Stevenson plans to step back from content creation by the end of July 2026. He has not specified whether he will continue his activism in other forms, but his book and public speaking engagements may continue.

The trade-off: Stevenson’s health has forced him to step back at a time when his influence was growing. His decision to prioritise well-being over platform growth is consistent with his critique of a system that demands constant growth at any cost.

For Gary Stevenson, the journey from elite trader to wealth-tax campaigner is not a contradiction—it’s the logical outcome of seeing the system from the inside. His YouTube channel, book, and media appearances have made him a prominent voice for economic reform, but his decision to step back in July 2026 raises questions about the sustainability of his activism. For his audience of young men and disaffected voters, the choice is clear: either take his arguments seriously and push for policy change, or watch another voice of insider critique fade away.
