Michael Rubin net worth: Michael Rubin is worth an estimated $9.6 billion as of August 2026, according to Forbes — down from a peak of $11.5 billion in August 2024. His fortune comes almost entirely from his roughly one-third stake in Fanatics, the private sports company he built after selling GSI Commerce to eBay for $2.4 billion in 2011. Because Fanatics is privately held, his wealth rises and falls with the company’s private valuation marks, not a stock price. Last updated: November 2026.
Who is Michael Rubin?
Michael Rubin is an American billionaire entrepreneur and the founder and CEO of Fanatics, the global sports merchandise, collectibles and betting company. He founded GSI Commerce in 1998, sold it to eBay for $2.4 billion in 2011, and used the buyback of Fanatics, Rue La La and ShopRunner to build a sports empire. He also co-founded the criminal-justice reform organisation REFORM Alliance and, in November 2026, got engaged to longtime partner Camille Fishel. Read his full story in Michael Rubin’s biography.
How the money breaks down
Rubin’s wealth is concentrated in a single asset: his stake in Fanatics. Bloomberg calculates that he owns about 33 percent of the company; an earlier Forbes estimate put his holding at around 43 percent. At the company’s $31 billion valuation in December 2022, a 33 percent stake is worth roughly $10 billion — close to the whole fortune. At the lower $25 billion mark reported for 2024, the same stake is worth about $8.3 billion, which explains most of the movement in his published net worth.
- Fanatics stake (~33%): the overwhelming majority of his wealth — roughly $8–10 billion depending on the valuation mark.
- Rue Gilt Groupe: a minority stake as executive chairman of the online luxury retailer (RueLaLa.com, Gilt.com); no published valuation of his holding.
- Real estate: a Bridgehampton oceanfront estate bought for $50.15 million in 2020; a Hollywood Hills home once owned by Ronald Reagan, bought for $70 million in September 2022; and a New York City penthouse reported at $43.5 million in 2018.
- Former asset — 76ers and Devils stake: about 10 percent of Harris Blitzer Sports & Entertainment, sold in October 2022. Forbes valued the stake at roughly $250 million; the deal terms were never disclosed, so no sale price is counted here.
Fanatics valuation history
| Date | Event | Valuation |
|---|---|---|
| August 2020 | Series E, $350 million | $6.2 billion |
| August 2021 | $350 million raise; MLB/NFL trading-card rights | $18 billion |
| March 2022 | $1.5 billion raise | $27 billion |
| December 2022 | $700 million round led by Clearlake Capital | $31 billion |
| 2024 | Employee-share transaction | ~$25 billion |
| March 2025 | Fidelity fund mark | ~$25.1 billion |
| November 2025 | Investment-fund assessment (not a priced round) | ~$33.5 billion |
The table shows why the estimates move: each new funding round or fund mark re-prices the same stake. The December 2022 round is the last priced financing; later marks are fund assessments, not transactions.
Net worth over time
- Pre-2021: about $3.5 billion (Forbes) — before the big Fanatics funding rounds.
- August 2021: about $6.2 billion, tracking the $18 billion Fanatics valuation.
- August 2024: $11.5 billion — the peak, per both Forbes and the Bloomberg Billionaires Index (ranked #266 globally by Bloomberg at the time).

How the estimate is made — methodology
Michael Rubin’s net worth is a private-company estimate, and it should be read with that caveat. Fanatics has never gone public, so there is no market price for his shares. Forbes and Bloomberg value his stake by applying his ownership percentage — about 33 percent by Bloomberg’s calculation, up to 43 percent in an earlier Forbes estimate — to the latest Fanatics valuation, then adding real estate and other holdings and subtracting known debts. The headline figure in this article, $9.6 billion, is Forbes’ latest dated figure (August 26, 2026). The $11.5 billion figure is the August 2024 peak reported by both Forbes and Bloomberg; no current (November 2026) Bloomberg figure could be verified, and it is not presented as current. Celebrity Net Worth’s $12 billion figure is not used as a headline because it is an aggregator estimate, not a reported Forbes or Bloomberg figure. Real-time tracker figures near $11.7 billion in November 2026 come from third-party aggregators, not from Forbes itself, and are not treated as verified. Because the Fanatics mark drives the total, Rubin’s fortune can move by billions of dollars between funding rounds without any change in the underlying business.
