Introduction to Wealth Lists and Public Fascination

• Forbes and Bloomberg publish richest people lists as popular business publications
• Top Google searches for celebrities = net worth queries
• Society uses wealth accumulation as universal success benchmark
• Forbes billionaires list requires dozens of reporters, many hours of work
• Most people don't know their own net worth accurately

Net Worth Calculation Fundamentals

• Formula: Assets minus liabilities = net worth
• Math is simple, getting reliable data is extremely difficult
• Challenge: Billionaires are very protective of privacy
• Hedge fund managers (Ray Dalio, Jim Simons, David Shaw) frequently in top 100
  • Don't know day-to-day asset composition due to algorithmic trading
  • Frequently trade in/out of positions based on advanced algorithms

Bloomberg's Methodology and Reliability

• Bloomberg most reliable list publisher with published methodology
• Primary business: selling market data to financial firms
• Bloomberg terminals start at $24,000/year for single user standard license
• Billionaires list = marketing tool for terminal subscriptions
• Bloomberg terminal = industry standard for big finance firms
• Bloomberg billionaires index updated daily at NYSE close
• New billionaire created every 26 hours (described as "frightening")

Public Company Founders - Easy Calculations

• Wealth strongly correlated with publicly traded companies
• Jeff Bezos example: owned <10% of Amazon
  • Market cap ÷ 10 + documented assets (mansion, private jets, space company)
• SEC filing requirements for large shareholders:
  • 5-10% ownership: Form 13D or 13G (beneficial owner)
  • >10% ownership: Form 3
  • Purpose: level playing field, prevent market manipulation
• 13G = passive investor, 13D = potential company changes
• Bloomberg terminal can lookup filings by individual for 5%+ stakes

Bill Gates Case Study

• Sold most Microsoft shares, diversified through Cascade Investments
• Holdings tracked through private investment firm filings
• Alternative investments: 270,000 acres farmland, Seattle home, $50M Leonardo da Vinci manuscript
• Net worth calculation: total assets minus $20B pledged to charitable foundation
• Gates has good reputation for following through on charity pledges

Private Company Valuation Challenges

• Tightly held private companies = much harder to value
• No public reporting requirements, less average investor involvement
• Kylie Cosmetics example:
  • Kardashian-Jenner family claimed Kylie = youngest self-made billionaire
  • Business valuable but not liquid (difficult to convert to cash)
  • Value dependent on Jenner's continued involvement
  • No longer considered billionaire by reputable publications
  • Would need 5x wealth to make bottom of Bloomberg index

Bloomberg's Private Company Framework

• Compare to similar size/industry public companies
• Subtract 5% liquidity adjustment (hard to sell private businesses)
• Additional 25% subtraction for "key man risk"
  • One individual has disproportionate influence on success/failure
  • Trump example: personal brand worth significant money in certain markets
  • Mar-A-Lago couldn't charge $200K/year membership fees without Trump

Hedge Funds and Alternative Investments

• Large share of Bloomberg index but tricky to value
• Method: look at assets under management (AUM) through SEC ADV forms
• ADV form required for funds >$25M
• Lists key officers and total client asset value
• Imperfect strategy: Jim Simons' Renaissance Technologies worth more than another fund with $130B AUM
  • Higher fees, higher returns, lower expenses
• Bloomberg admits this isn't perfect science

Confidence Rating System

• Bloomberg includes star rating for confidence in net worth figures
• 1 star: companies/assets impossible to accurately value
• 5 stars: entirely liquid publicly traded companies with verifiable valuations
• Business valuation complex even with full financials access

Hidden Wealth and Detection Limitations

• Much wealth not on public record
• Only attributed to individuals with >5% company ownership
• Well-diversified portfolios avoid concentration requirements
• Multi-billionaires can exist undetected by index
• Celebrity net worth predictions completely unreliable
  • Bloomberg techniques don't work on celebrities
  • Most would get 1-star rating
  • Celebrity net worth sites not rigorous like Bloomberg

Direct Contact Method

• Bloomberg contacts every billionaire through representatives
• Asks to comment on wealth estimate validity/accuracy
• Most choose not to comment
• Some try to adjust figures up/down for public image reasons
• Likely adjustments to appear less wealthy, avoid public attention

Notable Omissions

• Michael Bloomberg ($77B estimated by Forbes) not on own list
  • Company policy: no reporting on own company/founder/CEO
• Porsche Piëch family missing despite enormous fortune
  • Own 100% voting power, 50% of company owning Volkswagen + subsidiaries
  • Stayed off list through clever corporate structuring
