Jonas Siegenthaler is a Swiss professional ice hockey player who is a defenceman for the New Jersey Devils of the NHL. Born on May 6, 1997, he is the first known NHL player of Thai descent, because his mother is from Thailand.
Bilanz, the Swiss business magazine, put his fortune at CHF 5–10 million in its 2026 ranking of the 100 richest people in Switzerland under 40, published on April 28, 2026. That is about $6 million to $12 million at the November 6, 2026 exchange rate. Bilanz prints fortunes as ranges, not single numbers, so we show the range exactly as published.
How the estimate works
Bilanz publishes a yearly list of the 100 richest young people in Switzerland, mixing entrepreneurs, heirs and a handful of stars. Siegenthaler is one of the sportspeople on the 2026 list, with an estimated fortune of CHF 5–10 million. The magazine's own research and estimates, not tax records or official filings, are behind the number.
The ranking counts people who hold a Swiss passport or live in Switzerland, even if they play abroad, and fortunes are shown in Swiss francs in bands such as 10 to 20 million or 20 to 50 million. We use the low end of the band only to sort Siegenthaler against other athletes on this site, and we never show a single made-up figure.
