Who is Gary Stevenson’s wife?
Does Gary Stevenson have a partner?
Stevenson is married, but his wife’s name has not been made public. In his memoir The Trading Game, he refers to a girlfriend by the nickname “Wizard” but does not identify her by name (The Guardian). No public record in the gathered sources confirms a spouse’s identity (MediaRoar).
Gary Stevenson married
There is no official confirmation of a marriage date or ceremony. Stevenson keeps his personal life private, and neither his LinkedIn profile (LinkedIn) nor his Wikipedia page mention a spouse. The implication: any public claim about his wife’s name or background is unverified.
How rich is Gary Stevenson?
How much did Gary Stevenson make?
Stevenson earned a significant income as a trader at Citigroup. A Financial Times feature describes him as the most highly compensated trader on Citi’s bond trading floor. He reportedly gave away much of his wealth to charity after leaving the industry (The Guardian).
Gary Stevenson net worth
Estimates of his net worth range from £1 million to £5 million, but no verified figure exists (MediaRoar). The uncertainty stems from his private financial disclosures and the fact that he left trading several years ago.
For a campaigner urging a wealth tax on the super-rich, his own wealth is a frequent topic of curiosity. The lack of a clear figure fuels both scepticism and interest.
The catch: without audited accounts, any net worth number is speculative.
How did Gary Stevenson become a millionaire?
What did Gary Stevenson trade?
He traded interest rate derivatives, a complex financial product that bets on movements in central bank rates. Starting at Citigroup in 2008 after winning an internal trading competition (The Guardian), he became the bank’s most profitable trader in 2011 (Wikipedia). His bonuses and trading profits made him a millionaire by age 27.
Stevenson studied economics and mathematics at the London School of Economics before joining Citi (Wikipedia). The pattern of his career: elite academic background, prestigious bank, rapid rise, early exit.
What has happened to Gary Stevenson?
What does Gary Stevenson do now?
He left trading in 2014 (The Guardian) and launched the YouTube channel Gary’s Economics in 2020 (Big Issue). The channel has grown to over 1 million subscribers, according to some profiles (French Wikipedia). In July 2026, he announced he was quitting the channel due to health concerns (The Guardian).
He also published a memoir, The Trading Game, with Penguin Books in 2024 (The New York Times). The New York Times called it a coming-of-age tale from the world of London high finance.
Stevenson built a fortune inside the financial system he now criticises, then gave up the high life to campaign against it. His YouTube following shows that many people are drawn to that contradiction.
His trajectory encapsulates the tension between insider knowledge and outsider critique.
What are Gary Stevenson’s political views?
Gary Stevenson documentary
A Channel 4 documentary titled How to Get Filthy Rich with Gary Stevenson was released in July 2026 (The Guardian). It examines wealth inequality in the UK and argues for a wealth tax on the super-rich (Wikipedia).
Gary Stevenson Go West
Stevenson has been a vocal critic of austerity and economic inequality. He has argued that a 2% wealth tax on assets above £10 million could raise £24 billion a year for the UK Treasury (The Guardian). His views align with left-wing economic thinkers, though he frames his arguments in the language of a former insider.
The trade-off: his policy proposals are popular with progressive audiences but face stiff opposition from the political right and financial industry lobbies.

In his own words and others’
“I left because I saw the inequality growing.”
Gary Stevenson, on leaving trading (The Guardian)
“The Trading Game is a coming-of-age tale from the world of London high finance.”
The New York Times
“A 2% wealth tax on wealth above £10 million could raise £24 billion a year for the UK Treasury.”
Gary Stevenson, as reported by The Guardian
For the UK public, Stevenson’s story poses a real question: Does a former insider’s call for a wealth tax carry more credibility than a career politician’s? The documentary airing on Channel 4 will test that. Stevenson’s next move, after stepping away from YouTube, could determine whether his influence outlasts his online presence.
