The claim about IGV's trading volume reaching $10.96 billion is supported by credible, authoritative sources that directly report trading volume statistics. The official ETF statistics site and the iShares BlackRock product page are highly authoritative sources likely to contain the most accurate and verified figures. Market data providers with high relevance also show consistent trading volume figures close to the claimed number. Additionally, the CNBC report relaying the figure from The Kobeissi Letter adds corroboration, although it is secondary in nature. There is no evidence from any reputable source contradicting the reported $10.96 billion volume. The combination of high-authority primary sources and consistent supporting market data suggests that the statement is highly likely to be true.
