The core of the claim—a massive ~$3 billion outflow from GLD on a single day in early March 2026—is corroborated by financial data reports. Specifically, Barchart reported a $2.91 billion outflow on March 4, 2026. While the 'two years' vs 'decade' record description varies by source, the magnitude and timing are accurate. The broader context of commodity outflows and Bitcoin ETF activity during this period is also supported by market summaries from ETF Action and Morningstar.
