Bryan Johnson’s net worth is estimated at $400-500 million in 2026. He built that fortune by selling payment processing company Braintree to PayPal for $800 million in 2013. Now he’s spending approximately $2 million per year trying to reverse his biological age through a protocol called Blueprint. Whether you think he’s a visionary or a cautionary tale depends on how you feel about a 48-year-old man getting blood transfusions from his teenage son.
Johnson represents something new in the Longevity Era. He’s not a doctor marketing wellness, not a podcaster selling supplements. He’s a tech entrepreneur who decided to treat his body like a startup, complete with metrics dashboards, A/B testing, and a burn rate that would make most VCs nervous.
How Bryan Johnson Made His Money
Johnson’s wealth traces back to a single transaction. In 2007, he founded Braintree, a payment processing company based in Chicago. The company’s breakthrough came when it acquired Venmo in 2012 for $26.2 million. One year later, PayPal (then owned by eBay) acquired Braintree for $800 million in cash. As founder and CEO, Johnson’s stake generated an estimated $300-400 million before taxes.
Following the sale, Johnson launched OS Fund in 2014, a venture capital firm investing $100 million in frontier technology companies working on genomics, synthetic biology, and artificial intelligence. He then founded Kernel in 2016, a neurotechnology company building devices to measure brain activity. Kernel raised over $110 million in funding. These ventures diversified his portfolio beyond the Braintree exit.
The Blueprint Protocol: What $2M/Year Buys
In 2021, Johnson launched Project Blueprint, a comprehensive anti-aging regimen managed by a team of over 30 doctors and health professionals. The protocol involves over 100 daily supplements, rigorous dietary restrictions, extensive medical testing, and experimental treatments. According to Bloomberg’s detailed reporting, the annual cost runs approximately $2 million.
The daily routine starts at 5 AM with precise caloric intake, carefully measured supplements, and monitored biomarkers. Johnson tracks over 70 organs through regular testing. His team publishes the data openly. The results have been polarizing. Johnson claims his heart functions like that of a 37-year-old and his fitness levels match a typical 18-year-old. Critics point out that many of his results reflect benefits achievable through basic exercise, sleep, and nutrition at a fraction of the cost.
Bryan Johnson Net Worth Breakdown
Calculating Johnson’s precise net worth involves several components. The Braintree exit provided the foundation. OS Fund investments in companies like Ginkgo Bioworks (which went public at a $15 billion valuation) and others have generated returns. Kernel represents both a substantial investment and a potential future payoff if neurotechnology scales commercially.
However, Johnson’s spending rate is extraordinary. Beyond the $2 million annual Blueprint cost, he funds a full-time medical team, maintains research operations, and invested heavily in Kernel. Conservative estimates place his current liquid net worth at $400-500 million after a decade of significant expenditure. Forbes has not included Johnson on its billionaire list, suggesting his total assets remain below $1 billion.
The Don’t Die Movement
Johnson expanded Blueprint into a consumer brand called Don’t Die. The product line includes Olive oil supplements and a “Blueprint Stack” of daily supplements priced for consumers at a fraction of his personal protocol’s cost. This pivot from personal experiment to consumer brand mirrors the trajectory of Dave Asprey’s Bulletproof Coffee empire, though Johnson’s marketing leans harder on scientific data than lifestyle aspiration.
The Don’t Die brand also includes a book, documentary appearances, and a social media presence that reaches millions. Johnson’s willingness to document everything publicly, including the controversial plasma exchange experiment with his son, generates enormous earned media value. Love him or hate him, the algorithm rewards his transparency.
Controversies and Criticism
The “blood boy” headlines wrote themselves. In early 2023, Johnson underwent a plasma exchange procedure involving his 17-year-old son Talmage and his 70-year-old father. The procedure, called plasmapheresis, has limited evidence supporting anti-aging benefits. Johnson discontinued it after the data showed minimal improvement, but the publicity cemented his reputation as someone willing to push ethical boundaries in pursuit of longevity.
Medical professionals have offered measured criticism. While individual components of Blueprint like exercise, sleep optimization, and plant-based nutrition have strong evidence, the extreme supplementation and experimental treatments lack long-term safety data. Peter Attia, who represents the more conservative end of longevity medicine, has notably avoided endorsing Johnson’s approach despite sharing similar goals.
Bryan Johnson’s Influence on Longevity Culture
Whether or not Blueprint delivers on its promises, Johnson shifted the Overton window for anti-aging investment. Before Blueprint, spending significant money on longevity was considered eccentric. After Blueprint, it became a recognized category in wealth management conversations. Family offices now allocate to longevity as an asset class. Concierge medicine practices report increased demand from clients referencing Johnson’s approach.
His real legacy may be economic rather than scientific. By making anti-aging aspirational and data-driven, he created market demand that funds legitimate research. The $29 billion longevity industry benefits from every headline Johnson generates, even the controversial ones.

Frequently Asked Questions
What is Bryan Johnson’s net worth in 2026?
Bryan Johnson’s net worth is estimated at $400-500 million in 2026. His wealth primarily comes from selling Braintree to PayPal for $800 million in 2013, supplemented by returns from OS Fund venture investments and his stake in Kernel neurotechnology. His net worth has decreased from the post-sale peak due to substantial spending on Blueprint, Kernel development, and philanthropy.
How did Bryan Johnson make his money?
Bryan Johnson made his fortune by founding Braintree, a payment processing company, in 2007. Braintree acquired Venmo in 2012, and PayPal then acquired the combined company for $800 million in cash in 2013. Johnson’s stake as founder generated an estimated $300-400 million before taxes. He subsequently invested through OS Fund and founded Kernel.
How much does Bryan Johnson spend on anti-aging?
Bryan Johnson spends approximately $2 million per year on his Blueprint anti-aging protocol. This covers a team of over 30 medical professionals, 100+ daily supplements, extensive diagnostic testing, experimental treatments, and specialized nutrition. His consumer brand Don’t Die offers simplified versions of the protocol at significantly lower price points.
Does Bryan Johnson’s Blueprint protocol actually work?
Results are mixed. Johnson’s team publishes biomarker data showing improvements in cardiovascular function, inflammation markers, and fitness metrics. However, medical experts note that many of these improvements are achievable through standard healthy lifestyle practices at dramatically lower cost. The experimental components like plasma exchange have shown limited benefits. No long-term safety data exists for the full protocol.
