Multiple credible and relevant sources report that ARK Invest purchased approximately $15.2 million worth of Coinbase shares and that Coinbase's stock rose about 16% around the same time. The most relevant reports from Investing.com and The Block both provide consistent information about the purchase amount and the price surge, directly aligning with the statement. Although secondary sources such as CryptoRank and CoinMarketCap Academy repeat this information rather than cite official filings, they are consistent with ARK’s public trading disclosures. The CNBC market wrapup has limited relevance but does not contradict the claim. Yahoo Finance mentions a later sale rather than a purchase, which refers to a different timeframe and therefore does not undermine the statement. Considering the agreement among key primary reports and absence of any direct contradictions, the information is well supported and the statement is very likely accurate.
