The claim is an accurate summary of the X post by @KobeissiLetter (https://x.com/KobeissiLetter/status/2056811246801113562), published May 19, 2026. The post's figures are internally consistent: $8T + $9T + $10T + $4T = $31T cumulative since 2023, matching the claim exactly. The Kobeissi Letter is a prominent financial commentary account that routinely cites Federal Reserve Flow of Funds (Z.1) and DFA data for household equity ownership statistics. The Federal Reserve DFA table (federalreserve.gov/releases/z1/dataviz/dfa/distribute/table/) is the canonical source for such ownership share data, but its interactive content could not be directly verified in this run. The ~40% household ownership share and the year-by-year equity gain figures are plausible given documented equity market performance over 2023-2026. Confidence is medium rather than high because no independent primary data source (e.g., a Fed Z.1 release or Bloomberg data) was directly confirmed; the claim rests on a single social media post without a cited primary source link.
