Cathie Wood's ARK Loads Up on Tempus AI, Cuts Roku and Block

July 10 – Cathie Wood’s ARK Invest purchased 150,563 shares of Tempus AI (NASDAQ:TEM), worth about $8.8 million, according to a Wednesday regulatory filing with the SEC.

The bulk of the buy flowed through the ARK Innovation ETF (ARKK), with the remainder acquired via the ARK Genomic Revolution ETF (ARKG). Tempus AI applies artificial intelligence to clinical decision?making, a focus area for Wood’s disruptive?tech strategy.

At the same time, ARK trimmed its position in Roku (NASDAQ:ROKU), selling 50,823 shares, roughly $4.5 million, also via ARKK. This marks a second consecutive day of reductions in the streaming platform stock.

The fund likewise pared back exposure to Block, offloading 56,503 shares worth about $6.5 million, as part of a broader pullback from fintech names.

These moves illustrate ARK’s ongoing pivot toward AI health plays and away from streaming and payments.
