Person profile
Co-founder and chief executive of Atlassian
"Valued as of" is the effective date of the market closes, exchange rates, and filings inside the estimate. "Sources checked" is when the pipeline last verified those sources successfully. A weekend check can confirm a Friday valuation without inventing weekend movement.
As of September 4, 2026, Mike Cannon-Brookes's estimated net worth is about $9.0B(9.0 billion US dollars). That places Mike Cannon-Brookes at #22 among the people Net Worth Leader currently tracks.
This is an estimate of assets minus documented liabilities. It is not a cash balance, and many holdings may be restricted, pledged, illiquid, or difficult to value.
Mike Cannon-Brookes co-founded Atlassian in 2002 with Scott Farquhar and has been its sole chief executive since 2024. His estimate values the high-vote Class B shares his family trust reports in its May 2026 Schedule 13G/A at Atlassian's Class A price.
The two founders bootstrapped Atlassian on a credit card, built Jira and Confluence into standard developer tools, listed on Nasdaq in 2015, and redomiciled the company to the United States in 2022. Cannon-Brookes also invests in renewable energy through his private vehicle.
The estimate tracks Atlassian's share price. Scheduled sales of Class A shares under prearranged plans reduce the count gradually.
Mike Cannon-Brookes's estimate declined mainly because Atlassian Corporation shares decreased from the prior comparable close.
A one-day estimate change is not the same as income, profit, or a realized gain or loss.

Liabilities without a documented value are never shown as zero; they are simply not included, and that limitation is part of source coverage below.
100.0% of this profile's modeled gross value is supported by Tier 1 or Tier 2 evidence (primary filings, official documents, licensed market data, or audited accounts). The profile carries a strong coverage label.
No meaningful range beyond the central estimate is supported for this profile, so only the central value is published. Unknown liabilities are not evidence that no liabilities exist. No personal liability is documented for this profile, so none is deducted.
The timeline runs from June 12, 2026 to September 4, 2026; the latest estimate is higher than the first point. Points before August 20, 2026 are labeled modeled reconstructions: today's reviewed ownership records applied to the closing prices of each earlier market date. Published history begins August 20, 2026 and grows one point per completed market date.
