Quick Answer: No major financial outlet publishes a verified net worth for Jack Mallers. Net worth websites estimate it at about $50 million to $100 million, including Datawallet in an estimate updated August 9, 2026, but those figures rest on assumptions, because his stake in Strike and his personal bitcoin holdings have never been disclosed. Mallers is the founder and CEO of Strike, the bitcoin financial services app, and he resigned as CEO and director of Twenty One Capital (NYSE: XXI) effective July 20, 2026, when the company also said it was no longer pursuing an acquisition of Strike. Blockchainreporter’s assessment: the $50 million to $100 million range is unverified, because neither his Strike stake nor his personal bitcoin holdings have been disclosed.
Our earlier version attributed a $50 million to $100 million estimate to Forbes. Forbes’ profile of Mallers, written for its 2021 30 Under 30 list, gives no net worth figure, so we have corrected that.
Key Takeaways
- Net worth: no verified figure from Forbes, Bloomberg or another major outlet; aggregator sites estimate $50 million to $100 million without disclosing their inputs
- Strike: Mallers is still Strike’s founder and CEO, according to its website; Strike says it serves 100+ countries, won a New York BitLicense in March 2026 and a MiCA license in Malta in June 2026
- Twenty One Capital: Mallers led XXI from its NYSE listing in December 2025 until July 20, 2026; the company held 43,514 BTC on June 30, 2026, worth about $3.5 billion at bitcoin’s October 28 price
- Separation: XXI’s filing says his departure was “not related to any disagreements with the Company” and sets out separation payments and option terms
- El Salvador: Strike worked with the government on the 2021 plan to make bitcoin legal tender; in January 2025, lawmakers made bitcoin acceptance voluntary for businesses

Jack Mallers Net Worth in 2026: What Is Known
Mallers’ Forbes profile page, last updated December 31, 2020, describes him as the founder of Zap Solutions and lists no net worth, and we found no figure from Bloomberg or other major financial outlets. The figures that circulate online come from net worth and crypto content websites.
Celebrity fortunes are estimated the same way; see, for example, how DJ Khaled built a $95 million empire.
| Source | Estimate | Date | Basis stated |
|---|---|---|---|
| Datawallet | $50 million to $100 million | Last updated August 9, 2026 | Strike equity, an undisclosed Twenty One stake, bitcoin bought since 2013 and other investments; the site says every published figure is an aggregator estimate, not a disclosure. XXI’s filings show it bought back his XXI shares in July 2026 |
| CoinCodex | $50 million in its fact table and $50 million to $100 million in its text, which elsewhere calls his net worth “probably well over nine figures” | No date shown; marked “updated 8 months ago” | No method stated |
| Forbes | No figure | Profile last updated December 31, 2020 | 30 Under 30 listing only |
What the inputs show:
- Strike equity: Strike is private. Its blog lists one funding announcement, an $80 million Series B led by Ten31 in 2022, which did not state a valuation, and Mallers’ ownership has not been disclosed.
- Bitcoin: Mallers has not disclosed how much bitcoin he holds personally.
- Twenty One Capital: XXI’s July 21, 2026 filing sets out separation payments and option terms under his separation agreement, and a Form 4 filed the same day shows that XXI bought back all of his Class A shares. The filings do not say what his options were worth; the agreement gave him 90 days from his departure to exercise them.
Because the largest inputs are not public, we do not publish our own estimate. An earlier version included a breakdown based on an assumed Strike valuation and founder stake; neither has been disclosed, so we removed it.

Who Is Jack Mallers?
Jack Mallers is a Chicago-based bitcoin entrepreneur best known for building payment apps on the Lightning Network, a system for fast, low-cost bitcoin payments. When Forbes named him to its 30 Under 30 Finance list for 2021, it described Zap Solutions as a bitcoin investment and payments company that transacts over Lightning, with a $3.5 million seed round led by Greenoaks Capital, about 20 employees and work underway with Visa. Forbes also wrote that he was introduced to bitcoin in 2013 through his father.
Mallers first built Zap, a Lightning wallet app, and then Strike, which the company says was founded in 2019 and launched publicly in January 2020. Our earlier report on Strike’s launch covers the original app. He also hosts “The Jack Mallers Show” on YouTube, which Strike links from its website.
Strike: The Company Mallers Runs
Strike is operated by Zap Solutions, Inc. from Chicago and lists Mallers as its founder and CEO. Its website says it is available in more than 100 countries and shows about 1.57 million app downloads; it does not publish a customer count beyond “millions.”
| Date | Strike milestone (official sources) |
|---|---|
| 2019 | Strike founded |
| January 2020 | Public launch |
| June 2021 | Expansion to El Salvador |
| September 2022 | $80 million Series B led by Ten31; Blackhawk, NCR and Shopify named as partners |
| May 2023 | Global launch in more than 65 countries |
| February 2024 | Strike Africa launches in seven countries |
| April and June 2024 | Strike Europe and Strike UK launch |
| December 2024 | Bill Pay launches |
| May 2025 | Bitcoin-backed loans launch |
Products in 2026. Strike lets customers buy bitcoin from $1 up to $2.5 million per order, set recurring buys, withdraw to their own wallets with free on-chain withdrawals, receive paychecks by direct deposit and pay bills from a bitcoin balance. Strike Private serves high-net-worth clients, family offices and institutions, and Strike Business offers treasury, payroll and invoicing tools. Bitcoin-backed loans are available in select US states, and Strike warns that price falls can trigger margin calls and liquidations.
2026 launches. In March, Strike said New York’s Department of Financial Services had granted it a BitLicense and a money transmitter license, and it began offering loans there in April. On June 30, it said its European entity, Zap (Strike) Europe Limited, had been authorized under MiCA, the EU’s crypto rules, by the Malta Financial Services Authority. On October 6, it launched interest on US dollar balances, currently 3.6% and paid in bitcoin, on cash held at Cross River Bank; Strike notes that it is not a bank.

Twenty One Capital: From NYSE Listing to Mallers’ Exit
Twenty One Capital is a bitcoin treasury company announced in 2025 with backing from Tether, Bitfinex and SoftBank. It went public through a merger with Cantor Equity Partners that closed on December 8, 2025, when its Class A stock began trading on the NYSE as XXI. Its closing filing named Mallers Chief Executive Officer, President and director, and listed Tether with 45.1% of the Class A shares, SoftBank with 25.7% and Bitfinex with 17.1%.
| Date | Bitcoin held by XXI | Source |
|---|---|---|
| December 8, 2025 (closing) | About 43,500 BTC | 2025 annual report |
| December 31, 2025 | 43,515 BTC | Q2 2026 quarterly report |
| June 30, 2026 | 43,514 BTC, fair value about $2.55 billion at $58,605 per BTC | Q2 2026 quarterly report |
| October 28, 2026 | About $3.54 billion at about $81,465 per BTC | Our calculation on the June 30 holdings |
XXI’s Q2 2026 quarterly report, filed August 11, is its latest disclosure of holdings. It reported a net loss of about $1.27 billion for the first half of 2026, mostly from the fall in bitcoin’s price, which dropped from $87,316 at the end of 2025 to $58,605 on June 30. On May 19, SoftBank transferred its Class A shares to Tether, and its Class B shares were cancelled.
The Strike deal that did not happen. On April 29, 2026, Mallers presented at the Bitcoin 2026 Conference on an operating strategy “centered on potential acquisition of Strike” and Elektron, a bitcoin mining platform, according to an XXI filing that identified him as Strike’s founder and CEO. The Block reported that Tether, XXI’s majority shareholder, had proposed a two-stage merger of the three companies.
Resignation. XXI’s July 21 filing said Mallers had resigned as CEO and director effective July 20, 2026, a departure “not related to any disagreements with the Company.” Raphael Zagury, an XXI director and founder of Elektron Enterprises, became CEO, and the company said it was no longer pursuing the acquisition of Strike while still considering an acquisition of Elektron Energy. Mallers wrote on X: “My life’s work remains Bitcoin. My Bitcoin company is Strike. The work continues,” according to The Block, which reported that XXI shares fell more than 14% to $4.54 after the news. In an August 11 letter, Zagury said Tether is XXI’s controlling shareholder and that the stock “trades at a material discount to the Bitcoin we hold.”
Jack Mallers and El Salvador
On June 5, 2021, at the Bitcoin 2021 conference in Miami, President Nayib Bukele announced in a video that he would propose making bitcoin legal tender in El Salvador. The Block reported that the government was working with Strike on the plan and quoted Mallers: “This is the shot heard ’round the world for Bitcoin.” Strike expanded to El Salvador that month, according to its timeline. Lawmakers approved the Bitcoin Law days later, and it took effect in September 2021.
The policy has since changed. In late January 2025, El Salvador’s Legislative Assembly voted 55 to 2 to make bitcoin acceptance voluntary for private businesses, following a $1.4 billion loan agreement with the International Monetary Fund reached in December 2024, The Block reported on January 30, citing Reuters. Our bitcoin price prediction tracks the asset at the center of Mallers’ companies.
How Has Jack Mallers Impacted the Cryptocurrency Industry?
Mallers’ impact comes mainly from promoting bitcoin as a way to pay, not only as an investment, from Strike’s role in El Salvador’s bitcoin law and from his time leading a listed bitcoin treasury company.
- Lightning payments. He built Zap, a Lightning Network wallet, and then Strike, whose operating company, Zap Solutions, Forbes described in 2021 as a bitcoin investment and payments company that transacts over Lightning. When Strike announced its $80 million Series B in 2022, it named Blackhawk, NCR and Shopify as partners.
- El Salvador. Strike worked with the government on the 2021 plan to make bitcoin legal tender and expanded to the country that June.
- Access to bitcoin. Strike says it operates in more than 100 countries and lets customers buy bitcoin from $1, withdraw it free to their own wallets and pay bills from a bitcoin balance. In 2026 it received a New York BitLicense and a MiCA license in Malta.
- Bitcoin treasury companies. He led Twenty One Capital, a NYSE-listed company that held 43,514 BTC on June 30, 2026, from its listing in December 2025 until he resigned effective July 20, 2026.
Some of these efforts have since been scaled back. In January 2025, El Salvador made bitcoin acceptance voluntary for businesses, and after Mallers left XXI the company said it was no longer pursuing an acquisition of Strike.
