Cathie Wood is doubling down on Palantir Technologies, highlighting her confidence in the company’s ability to lead the enterprise AI revolution as market dynamics reshape the competitive landscape. On Saturday, Wood responded to a post from Ark Invest's chief futurist Brett Winton, predicting Microsoft Excel's decline. Wood said she believes Palantir CEO Alex Karp’s assertion that the company will become the largest pure-play enterprise AI software firm. Palantir is Ark Invest’s second-largest holding after Tesla, with a stake valued at $640 million, or about 7% of Ark's total assets.
