Estimate

Current Assessment

The latest located SEC filing shows Buffett with 196,290 Berkshire Hathaway Class A shares and 1,162 Class B shares after a May 2026 charitable gift. At May 29 market prices, those shares were worth about $139.86 billion. Buffett has said he has no debts and that his Berkshire A shares account for well over 99% of his net worth. A small allowance for non-Berkshire assets brings the base estimate to roughly $140.3 billion to $140.8 billion.

Key caveats

The estimate changes almost dollar-for-dollar with Berkshire Hathaway’s share price.
Non-Berkshire assets are not publicly itemized.
Future charitable giving is not deducted until shares are transferred.
A newer SEC Form 4 would supersede the share count used here.

Evidence gaps

No audited personal balance sheet is public.
No current itemized cash, securities, real estate or tax-liability schedule was found.
No public evidence was found that updates Buffett’s June 2025 no-debt statement.

Confidence

Medium confidence

82/100

The draft is publishable and generally well supported. Identity is clear, the dominant Berkshire Hathaway share position is backed by SEC filings, and the market-value calculation is internally consistent. The main limitations are the unitemized non-Berkshire asset allowance, reliance on a June 2025 self-reported no-debt statement, and price sensitivity. The public estimate should be presented as a medium-confidence, as-of-date mark-to-market estimate rather than a high-confidence comprehensive personal balance sheet.

The core public-stock calculation is strong, but the draft’s Medium-High confidence label is slightly optimistic because the base range depends on a small residual asset allowance supported partly by a secondary Bloomberg model and a broad concentration statement, while liabilities are based on a self-reported June 2025 statement rather than current audited evidence. Medium confidence better matches the supplied source coverage and caveats.

Key Evidence Gaps

No audited personal balance sheet.
No itemized current cash, securities, private investments, real estate valuation, or tax-liability schedule.
No public evidence in the supplied artifacts updating Buffett’s June 2025 no-debt statement.
No confirmation that no newer Form 4 exists after the May 26, 2026 filing.
Market prices are timestamped and should be refreshed for publication if the as-of date changes.

Public Caveats

Estimate is as of May 29, 2026 and changes with Berkshire Hathaway share prices.
The Berkshire share count is based on the latest located Form 4 filed May 26, 2026; any later Form 4 would supersede it.
Non-Berkshire assets are not publicly itemized and are treated only as a small approximate allowance.
The no-debt assumption relies on Buffett’s June 2025 public statement, not an audited personal balance sheet.

Uncertainty Drivers

BRK.A and BRK.B prices move daily and dominate the estimate.
A newer Form 4 after May 26, 2026 would change the share count if another gift or conversion occurred.
Non-Berkshire assets are not itemized publicly; the estimate relies on Buffett’s concentration statement and secondary context.
The no-debt input is based on a June 2025 self-report, not a current audited personal balance sheet.
Potential tax effects, estate-planning structures or pledges are not visible from the reviewed sources.
