Multiple sources confirm the core claim. The Kobeissi Letter X post directly supports both the SOXS 1.3 billion-share figure (third-highest single-session US ETF volume in 20 years) and the record ~$90 billion leveraged/inverse ETF notional turnover. The cryptobriefing article independently confirms the 1.36 billion SOXS shares and the third-highest ranking. A Goldman Sachs/Bloomberg-referenced Substack further corroborates the 1.3 billion-share figure. The only minor inconsistency is a one-day date variation between sources (June 9 vs June 10), which does not undermine the substance of the claim; the 'Tuesday' framing aligns with June 9, 2026.
