Estimate

Current Assessment

Her largest visible asset is the Adelson family’s Las Vegas Sands stake. A 2023 securities filing showed the principal Adelson stockholder group would own about 392 million LVS shares after a stock sale tied to the Mavericks purchase. At a June 30, 2026 closing price of $46.19, that block was worth about $18.1 billion before discounts and taxes. The Dallas Mavericks stake is smaller but material: using a $5.1 billion Forbes team valuation, a roughly 69% family stake implies about $3.5 billion. The rest of the estimate reflects likely cash, dividends, private assets, and media holdings, calibrated against reputable wealth trackers that have placed Adelson in the $30 billion-plus range.

Key caveats

The estimate is for Miriam Adelson and attributable family-controlled wealth, because trusts and family vehicles obscure exact personal ownership.
The Mavericks stake should not be double-counted with external billionaire-list estimates.
Public stock values move daily and should be refreshed before publication.

Evidence gaps

Current 2026 LVS beneficial ownership filing was not located in accessible sources.
Exact split of Mavericks ownership among Miriam Adelson, Sivan and Patrick Dumont is not public.
Personal liabilities, tax obligations, and pledged shares were not disclosed in reviewed sources.

Confidence

Medium confidence

66/100

The estimate is supported by available evidence, with meaningful assumptions and caveats.

Key Evidence Gaps

Latest Las Vegas Sands proxy, Schedule 13D/G, or equivalent current beneficial ownership table.
Direct primary or top-tier evidence for the exact Adelson-Dumont Mavericks ownership percentage.
Direct Forbes, Sportico, or comparable current Mavericks valuation source instead of a Wikipedia-summarized Forbes table.
Direct current Forbes/Bloomberg billionaire profile access or equivalent transparent external net-worth calibration.
Documentation of private cash, dividends retained, media holdings, real estate, tax obligations, debt, pledges, or estate liabilities.

Public Caveats

This estimate is for Miriam Adelson and attributable family-controlled wealth, not a fully separable Miriam-only balance sheet.
The LVS share block is based on a November 2023 post-offering principal stockholder group share count marked to a June 30, 2026 market price; current beneficial ownership could differ.
The Mavericks stake is modeled as an approximate family-group stake because the exact split among Miriam Adelson, Sivan and Patrick Dumont, trusts, and other holders is not public.
The private-assets component is an implied bridge calibrated to external wealth trackers and is not directly documented from public filings.

Uncertainty Drivers

The exact split of Mavericks ownership among Miriam Adelson, Sivan and Patrick Dumont, family trusts, and other holders is not publicly clear.
The most recent accessible LVS beneficial ownership source was the November 2023 prospectus; later share transfers, sales, pledges, or estate planning could change the count.
External wealth trackers may include private assets, cash, taxes, and liabilities that are not visible in public filings.
The Mavericks valuation is a Forbes-derived secondary table, not a closed-market transaction on the access date.
Large blocks of public stock can be subject to liquidity discounts, tax effects, and control premiums depending on valuation purpose.
