Jack Dorsey’s net worth is $5 Billion. Jack Patrick Dorsey is an American technology entrepreneur and businessman, best known as the co-founder of Twitter, Inc. and the co-founder, principal executive officer, and chairman of Block, Inc. — the developer of the Square financial services platform. He is also the founder of Bluesky, the decentralized social media protocol.
Updated March 2026: According to Forbes’ real-time net worth tracker, Jack Dorsey’s net worth was estimated at approximately $6 billion as of early March 2026, consistent with the $5.9 billion figure cited by Forbes as of February 2026. His wealth is primarily tied to his stake in Block, Inc., whose stock performance fluctuates with broader fintech and cryptocurrency markets.
Jack Patrick Dorsey was born on November 19, 1976, in St. Louis, Missouri. Growing up, Dorsey developed an early interest in maps, transportation systems, and dispatch routing — a fascination that would later directly influence his thinking about real-time information networks. He attended Bishop DuBourg High School in St. Louis. He later enrolled at Missouri University of Science and Technology before transferring to New York University, which he attended but did not graduate from.
As a teenager, Dorsey became fascinated by how taxi cabs, emergency services, and courier companies communicated and coordinated through dispatch systems. He wrote open-source dispatch software while still in his teens, and his interest in these real-time communication networks became the intellectual foundation for both Twitter and the early concepts behind Square.
Dorsey co-founded Twitter, Inc. in 2006 alongside Evan Williams, Biz Stone, and Noah Glass. He served as the company’s first CEO from 2006 to 2008, during which the platform launched and began attracting its initial user base. After a period away from the CEO role, Dorsey returned as CEO from 2015 to 2021, during which Twitter went through significant product evolution, content moderation controversies, and a period of renewed growth.
In 2009, alongside Jim McKelvey, Dorsey co-founded Square, Inc. (now Block, Inc.), a financial services company initially built around a small card-reader dongle that allowed small businesses and individuals to accept credit card payments via smartphone. Square went public in November 2015, and Dorsey retained a substantial ownership stake. The company subsequently acquired music streaming service TIDAL in 2021 and rebranded as Block, Inc. in December 2021. Block’s ecosystem includes Square (merchant payment processing), Cash App (peer-to-peer payments and banking), Afterpay (buy-now-pay-later), and TBD (a decentralized Bitcoin-focused platform).
In 2021, Dorsey stepped down as Twitter CEO for the second time, and the company was subsequently acquired by Elon Musk in October 2022 for $44 billion and rebranded as X. That same year, Dorsey founded Bluesky, a project originally incubated within Twitter to develop a decentralized social media protocol, which launched publicly in 2023 and grew rapidly as an alternative to X.
As of March 2026, Dorsey remains CEO of Block, Inc., though the company has faced significant challenges. A March 2026 Forbes analysis noted that Block has struggled to recapture the growth momentum of its earlier years.
Dorsey’s wealth is almost entirely derived from his equity positions in the companies he co-founded and led:
Jack Dorsey has never married and has no children, according to public records. He is known for an ascetic personal lifestyle that includes intermittent fasting (often eating one meal per day), daily meditation, cold water therapy, and long-distance walking.

Dorsey is based primarily in Miami, Florida, having relocated from San Francisco around 2022. He is an avid user of Bluesky and has posted extensively about his personal philosophies, technology views, and Bitcoin advocacy. His minimalist aesthetic extends to his personal style — he is frequently photographed in simple t-shirts.
