Jean-Yves Thériault Net Worth: How Estimates Are Built

The Jean-Yves Thériault most people are searching for is the Canadian kickboxer from Paquetville, New Brunswick, nicknamed "The Iceman" and credited with 23 world kickboxing championship titles. As of June 2026, the most credible estimate puts his net worth in the range of $1 million to $2 million USD, driven primarily by his long-term involvement with the Therien Jiu-Jitsu and Kickboxing school network, event promotion through the Iceman Kickboxing Circuit, and residual income from his coaching and authorship work. That range is a reasonable estimate, not a verified figure, and this article explains exactly how it's built and where to be skeptical.

Who Jean-Yves Thériault actually is (and why searches get confusing)

Jean-Yves Thériault (the accented spelling is correct; the unaccented "Theriault" appears frequently in English-language business records but refers to the same person) is a retired professional kickboxer and martial arts instructor born in Paquetville, New Brunswick, Canada. He competed under the nickname "The Iceman," accumulated 23 world championship titles across his career, and officially retired as an athlete on December 1, 1995. After retiring, he transitioned into coaching and business, becoming associated with the Therien Jiu-Jitsu and Kickboxing school ecosystem based in Ottawa and surrounding Ontario communities. He is also co-author of the 1983 book "Full-Contact Karate" (with Joseph Jennings), which represents a minor but verifiable intellectual property asset.

The confusion in search results comes from a few directions. First, the name "Jean Thériault" or "Jean Yves Thériault" appears across multiple unrelated Canadians. A Quebec real estate figure named Jean Thériault appeared in news coverage around a 4.5 million dollar property sale tied to alleged fraud in 2013 - that is a completely different person. A LinkedIn profile links a "Jean Yves Theriault" to a company called T.R.A.K.E.D. Properties - also not the kickboxer. A federal corporation registry entry for "Gestion Yves Thériault Inc." in Laval, QC, has not been confirmed as connected to the athlete. If you are pulling financial data on those individuals and attributing it to the kickboxer, the numbers will be wrong. Always cross-reference with the "Iceman" nickname, the Paquetville birthplace, the 23-title record, or the Therien martial arts connection before trusting any financial figure you find.

The financial signals that actually exist on the public record

Thériault does not have a celebrity-level public financial footprint. There are no disclosed earnings, no Forbes listings, and no documented real estate holdings tied specifically to him. What the public record does offer is a set of income-generating activities that can be used to build a reasonable estimate.

Martial arts school involvement

The Better Business Bureau lists "Jean Yves Theriault, Owner" in the business profile for Therien Jiu-Jitsu and Kickboxing in Ottawa. The Therien Martial Arts official site describes him as one of the martial arts legends behind the programs, alongside John Therien. The Therien Orleans site refers to him as a "former World Kickboxing Champion" tied to active instruction and organizational presence. Martial arts schools at this level typically generate revenue through monthly memberships, private instruction, belt testing fees, and merchandise. An established multi-location Ottawa-area school could plausibly generate owner-level income in the range of $60,000 to $150,000 CAD annually, though ownership structure and exact profit share are not publicly documented.

Event promotion

Tapology's event database lists Thériault under "Ownership" for the Iceman Kickboxing Circuit, indicating a promotional role at the event level. Martial arts and kickboxing promotion at the regional or national Canadian level is typically a modest revenue stream, often cyclical and dependent on ticket sales, sponsorship, and media deals. This income is real but hard to quantify without insider financial data.

Book royalties and licensing

The 1983 book "Full-Contact Karate" is a verified publication with his name attached. Royalties on a 40-plus-year-old instructional martial arts book are likely negligible today, perhaps a few hundred dollars annually at most, but it remains a real intellectual property asset. His championship profile and the "Iceman" brand may also carry licensing or appearance fee potential, though no specific contracts are documented publicly.

How net worth estimates like this are actually built

When there is no disclosed financial data, estimators (including this site) use a combination of income modeling and asset inference. The basic framework works like this: identify all plausible income streams, estimate annual earnings per stream using industry benchmarks, apply a savings and investment rate assumption over the person's working life, subtract likely lifestyle costs, and add any identifiable asset values. For someone like Thériault, who has been professionally active since the 1970s and is still operating in martial arts business, the accumulation window is long but the income scale is modest compared to, say, a mainstream sports celebrity.

The key assumptions in his case include: that his peak competitive earnings during the 1980s and early 1990s were in the range typical for elite Canadian kickboxers of that era (limited prize money compared to boxing or MMA; estimated $20,000 to $80,000 USD per year at peak); that his post-retirement school and coaching income has been steady but not transformative; that he has had roughly 30 years of post-retirement business income; and that no single documented windfall event (a major property sale, an equity exit, a large inheritance) has been identified. With those assumptions, a net worth accumulation in the low-to-mid seven figures in Canadian dollars is plausible, which roughly maps to $1 million to $2 million USD depending on exchange rates and asset composition.

Reconciling the conflicting numbers you'll find online

Two sources provide specific figures worth addressing directly. People.ai estimates his 2026 net worth at $1.88 million USD, with a year-by-year growth sequence going back to $1.13 million in 2022. Vipfaq displays a figure of approximately $1 million USD. Here is how to think about those numbers.

The People.ai figure of $1.88 million is not implausible, but the methodology disclaimer ("calculated based on a combination social factors") is a red flag. That phrasing typically means the figure is generated by an algorithm trained on fame signals, social media presence, and keyword traffic rather than actual financial investigation. The year-over-year growth pattern looks too smooth and linear to reflect real-world wealth accumulation, which tends to be lumpy. Vipfaq's lower figure may simply be pulling from an older dataset or a different underlying formula. Neither source should be treated as authoritative. The useful takeaway is that both land in roughly the same ballpark as a research-based estimate, which is mild corroboration that the true figure is probably not wildly different from $1 million to $2 million USD.

What his net worth range most likely is today

Working from the available evidence as of June 3, 2026, a reasonable net worth range for Jean-Yves Thériault ("The Iceman," the kickboxer) is $1 million to $2 million USD. If you are looking for Jean-Yves Thériault’s youri tielemans net worth figures, this range is the most defensible estimate based on his publicly visible income streams. The lower bound assumes modest savings from his competitive career, a partial ownership stake in the Therien school ecosystem, and limited accumulated investment assets. The upper bound assumes a meaningful ownership position in a multi-location school with tangible equity value, ongoing event promotion income, and long-term savings discipline over a 30-plus-year post-retirement business career.

The factors that would move the number meaningfully upward: if he holds significant equity in the Therien school locations as real property or as a formal ownership stake with documented value; if the Iceman Kickboxing Circuit has generated material profits over multiple years; or if there are undisclosed business interests (private corporations, real estate holdings) that have not surfaced in public records. The factors that would pull it downward: if his role in the school network is advisory or branding-only rather than ownership-level; if kickboxing promotion has been a loss-leader rather than a profit center; or if his peak competitive earnings were lower than industry benchmarks suggest.

The honest limits of estimating private wealth

Thériault is a private individual by any reasonable standard. He is not a publicly traded company, he does not file public financial statements, and he has not given interviews disclosing income or assets. Everything above is inference from public signals, which is legitimate as a methodology but inherently limited. A martial arts school owner in Ottawa is not subject to the same level of financial scrutiny as a listed athlete or a CEO of a public company. His actual net worth could be significantly higher or lower than $1 million to $2 million, and there is no way to close that gap without non-public information.

If you need to keep this estimate current, the most useful things to monitor are: any new Therien Martial Arts school openings or closings (which signal business value changes), any media coverage of the Iceman Kickboxing Circuit's events and their scale, any Canadian corporate registry filings under his name or close variants, and any public awards or recognition events that tend to surface biographical and professional updates. French-language Canadian media (particularly New Brunswick and Ontario outlets) have historically been more likely to cover him than English-language national sources, so broadening search language to include French terms like "champion du monde" alongside his name will return better results.

It is also worth noting that researchers interested in comparable profiles in the French and Francophone sports world may find useful methodological parallels in looking at how wealth is estimated for other Francophone athletes and entrepreneurs, since the income structures, tax environments, and disclosure norms across Canadian and European French-speaking contexts differ in ways that affect how estimates are built and what sources are available.

Bottom line for your research

Jean-Yves Thériault "The Iceman" has a publicly verifiable identity as a 23-time world kickboxing champion, martial arts school operator, event promoter, and author. The net worth figures you'll find online ($1 million to $1.88 million USD) are algorithmically generated but happen to align with a research-based estimate built from his known income streams. The $1 million to $2 million USD range is the most defensible estimate available today, with school equity and promotion income as the primary value drivers. The $1 million to $2 million USD range is the most defensible estimate available today, with school equity and promotion income as the primary value drivers youri latortue net worth. Treat any single number you find as a midpoint of a wide range rather than a precise figure, verify that whatever source you are reading is actually referring to the kickboxer and not one of several other Canadians who share his name, and revisit the estimate whenever new public information about the Therien school network or his promotion activities becomes available. If you are looking specifically for youri djorkaeff net worth, keep in mind that many sites reuse the same algorithmic approach for fighters and entrepreneurs when public financial data is limited.
