Estimate

Current Assessment

Williams' fortune is mainly tied to Twitter. The company's 2013 IPO filing listed him with 56.9 million shares, or 12.0% before the offering. Twitter later agreed to sell to Elon Musk for $54.20 per share in cash. A full-retention calculation would exceed $3 billion before taxes, but public reporting said Williams planned to sell 30% of his Twitter stock in 2017. After allowing for that sale, taxes, and unknown later transfers or investments, a roughly $2 billion estimate is the most defensible center point. Forbes' publicly indexed 2025 estimate of $2.0 billion is consistent with that range.

Key caveats

Exact Twitter sale history after the IPO is not fully public in the reviewed evidence.
Medium, Obvious Ventures, Mozi, and private investments may add value, but the public record does not support a precise number.
Company funding and venture fund assets are not counted as personal wealth.

Evidence gaps

Complete Form 4 sale ledger
Current private-company valuations and ownership percentages
Liabilities, taxes, philanthropy, and estate-transfer effects

Confidence

Medium confidence

72/100

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

Key Evidence Gaps

Complete Evan Williams Twitter Form 4 and sale proceeds ledger from IPO through the 2022 take-private.
Verified remaining Twitter share count or acquisition payout at closing.
Current transparent Forbes, Bloomberg, or equivalent wealth estimate as of July 2026.
Personal tax, residency, charitable transfer, estate planning, divorce, or liability evidence affecting net proceeds.
Current ownership percentages and valuation evidence for Medium, Mozi, Obvious Ventures economics, and private angel investments.

Public Caveats

This is a model-based estimate, not a complete personal balance sheet.
The largest component is inferred from Twitter's 2013 S-1 share count, a reported 2017 partial sale, and the 2022 $54.20-per-share acquisition price.
Exact post-IPO Twitter sale proceeds, taxes, transfers, liabilities, and remaining shares at acquisition were not fully reconstructed from the supplied evidence.
Medium, Obvious Ventures, Mozi, and other private investments are treated as qualitative context unless ownership and valuation data are public.

Uncertainty Drivers

Exact Twitter share sales after 2013 are not fully reconstructed in this source-limited run.
Tax basis, state residency, charitable transfers, divorce/estate planning, and liquidity management are unknown.
Medium, Obvious Ventures, Mozi, and personal angel-investment stakes have no public ownership-value disclosure in the reviewed sources.
Forbes' estimate is reputable but opaque and appears dated to May 2025 rather than July 2026.
