According to Mars Finance, on August 1, Bloomberg ETF senior analyst Eric Balchunas posted on social media that ARKK attracted $800 million in a single day - setting a record for the largest single-day inflow in history. This is likely due to the fact that the fund has surged 50% over the past three months, which is double the increase of SPY, QQQ, and IBIT. ARKW saw an inflow of $150 million, and the total inflow for the entire ARK series of funds approached $1 billion in a single day.
