Brian Armstrong was worth about $9.3 billion on Sept. 28, 2026. His giving philosophy differs from MacKenzie Scott because he backs targeted builder projects while she makes large unrestricted gifts to nonprofits.
Armstrong co-founded Coinbase, a U.S. cryptocurrency exchange, in 2012. His fortune rises and falls with Coinbase shares, while Scott's fortune rests on Amazon stock and her gifts flow much faster.

Where does Armstrong's money come from?
Armstrong holds roughly 14-19% of Coinbase stock, so his net worth moves almost in real time with COIN shares. That stake links his wealth directly to crypto markets rather than cash or diversified holdings.
Forbes estimated his net worth at about $9.3 billion on Sept. 28, 2026, ranking him 396th globally, according to Forbes real-time reporting via Datawallet in the Datawallet net worth profile. Other 2026 snapshots ranged from $7.7 billion to $10.5 billion as Coinbase shares fluctuated.
What does Armstrong try to build with gifts?
Armstrong signed the Giving Pledge in 2018 as the first crypto billionaire, pledging most of his wealth to education, level playing fields, and economic freedom, according to Philanthropy News Digest in the pledge announcement report. His approach favors starting or funding ventures that test a solution.
He founded GiveCrypto.org in 2018 to send direct cryptocurrency aid. Coinbase wound it down in December 2023 after concluding unconditional cash transfers alone did not create lasting change. Remaining funds went to Brink and GiveDirectly.
How does MacKenzie Scott give instead?
Scott received about 4% of Amazon in her 2019 divorce from Jeff Bezos. Forbes listed her at $28.6 billion and 84th globally on the March 1, 2026 billionaires list.
Through Yield Giving, she has donated over $26.3 billion in more than 2,700 gifts since 2019, according to Yield Giving in the official Yield Giving database. That total includes $7.1 billion in 2025, her largest annual total. Her philosophy is large, unrestricted, no-application gifts that let nonprofits decide how to use the money.
What is the core difference for wealth watchers?
Armstrong acts like a builder. He funds crypto aid trials, open-science infrastructure through ResearchHub, and longevity work through NewLimit and its focus on epigenetic reprogramming. The goal is new tools and research capacity.
Scott acts like a distributor. She moves large sums quickly, trusts recipients, and avoids narrow program rules. Readers tracking Armstrong should watch Coinbase shares for net-worth shifts, while readers tracking Scott should watch new Yield Giving entries because her 2025 pace set a record at $7.1 billion.
