Forbes estimates Mark Zuckerberg’s net worth at $243.3 billion (real-time estimate, 18 October 2026, #5 in the world). Most of it is his Meta stock: Meta’s 2026 proxy lists 639,347 Class A and 341,823,978 Class B shares as of 1 April 2026, which give him 60.8% of Meta’s voting power. The figure is an outside estimate that moves with Meta’s share price, not a number Zuckerberg or Meta discloses.
Zuckerberg started Facebook in 2004 and took it public in 2012; Forbes says he now owns about 13% of the company's stock.
02
Control through Class B shares
His 341.8 million Class B shares are 99.8% of that class and carry 60.8% of total voting power (Meta proxy, as of 1 April 2026), so he controls Meta while owning a minority of its equity.
03
Value set by the market
Because the share count is public, most movement in any estimate comes from Meta's share price, which in turn reflects Meta's results and spending.
04
Pledged to be given away
In 2015 Zuckerberg and Priscilla Chan pledged to give away 99% of their Meta stake over their lifetimes (Forbes).
What changed in 2025-26
A fortune riding on the AI build-out
In its Q2 2026 earnings release of 29 July 2026, Meta said it expects 2026 capital expenditures, including principal payments on finance leases, of $130-145 billion. Investors’ view of that spending now drives the share price and so the estimate.
Meta’s revenue was $60.8 billion in the quarter to 30 June 2026, up 28%, while operating income fell 8% to $18.8 billion as costs rose 55%, including legal charges and severance for the May 2026 headcount reduction.
Forbes' annual lists
On Forbes’ World’s Billionaires lists his estimate went from $56 billion in 2017 to $177 billion in 2024, $216 billion in 2025 and $222 billion in 2026; the real-time figure was $243.3 billion on 18 October 2026.
Control confirmed
The April 2026 proxy again shows Zuckerberg with 60.8% of the voting power, the reason Meta can keep spending heavily on AI with a founder, not outside shareholders, deciding.

What it means for you
Read any net-worth figure with three questions: who estimated it, on what date, and at what share price.
Compare figures only from the same outlet; Forbes, Bloomberg and others value private assets differently.
Look at the proxy for the share count and voting power; that part is disclosed, the dollar value is not.
Investors: dual-class control means one person decides on spending such as Meta's AI capex; price that governance in.
Founders: control and wealth can be separated; Class B shares kept Zuckerberg in charge with about 13% of the stock.
The Business Engineer lens
Zuckerberg’s fortune is a leveraged bet on Meta’s AI spending, and his voting control is what lets that bet be made without outside shareholders’ approval. The Business Engineer’s view is that founder control is now a strategic asset in the AI race: it allows capex on a scale that consensus boards would hesitate over.
Forbes estimates it at $243.3 billion (real-time, 18 October 2026), #5 in the world. It is an estimate that changes with Meta's share price.
How much of Meta does Zuckerberg own?
Meta's 2026 proxy lists 639,347 Class A and 341,823,978 Class B shares as of 1 April 2026, 99.8% of the Class B stock and 60.8% of total voting power; Forbes puts his ownership at about 13% of the stock.
Why do net-worth figures for Zuckerberg differ?
Each outlet multiplies the share count by the share price on a given day and adds its own estimate of other assets, so figures differ by source and date.
How did Mark Zuckerberg make his money?
By founding Facebook in 2004, now Meta, and keeping a controlling stake after the 2012 IPO.

In short
Forbes estimates Mark Zuckerberg’s net worth at $246.5B (real-time, 10 Oct 2026, #6 in the world). Most of it is his Meta shares: Meta’s latest filing lists 639,347 Class A and 341,823,978 Class B shares, 99.8% of Meta’s Class B stock and 60.8% of the total voting power. It is an outside estimate that moves with the share price, not a disclosed figure.
Correction (10 Oct 2026): this page previously showed undated or unsourced net-worth figures. We replaced them with one dated, named estimate and the holdings disclosed in filings, and we now tag every input as filing, reported or estimate.
How we source: figures on this page come from the company’s own filings (SEC 10-K, 10-Q, prospectus and earnings releases, or its annual report), with the period stated next to each number; outside estimates appear only labelled, with their source and date. Last refreshed October 2026. Our methodology.
An estimate is only as good as its date: it moves with share prices.
How much is Mark Zuckerberg worth?
The most widely cited figure is Forbes’s: $246.5B on 10 Oct 2026, #6 in the world. It is an outside estimate, not a figure Zuckerberg or any company has disclosed.
Other outlets publish different figures, and each changes with share prices. Use one source consistently, and always note its date.

Control confirmed in the proxy
Meta’s proxy lists 341.8 million Class B shares (99.8% of the class) and 60.8% of the total voting power.
What drives the number
Every estimate of Zuckerberg’s wealth is the same model: his Meta shares, times Meta’s share price, plus other assets (property, cash from share sales). The share count is public, so most of the movement comes from the share price.
Using one consistent source, Forbes’s annual World’s Billionaires lists, the estimate moved from $56.0B (Mar 2017) to $222.0B (Mar 2026). Because most of it is Meta stock, the line largely tracks the share price.

What he does now
He remains Meta’s chairman and CEO. Through his Class B shares he holds 60.8% of the voting power, so he controls the board and the company’s direction, including its shift to AI.
The Business Engineer view
What Zuckerberg’s fortune really measures
His share count is filed, so the estimate mostly tracks Meta’s share price. For founders with filed stakes, the share count is public and only the price moves; the estimate is then close to a measurement.
