ARK Invest Adds to Robinhood While Trimming AMD and Palantir Positions

Cathie Wood’s ARK Invest disclosed a fresh round of portfolio moves on Tuesday, expanding its stake in Robinhood Markets while continuing to reduce exposure to two other high-profile technology names: chipmaker Advanced Micro Devices (AMD) and software firm Palantir Technologies.

The trades, revealed through ARK’s daily disclosures, show the investment firm rotating within its actively managed funds. Robinhood, the retail trading platform, has been a recurring addition to ARK portfolios in recent sessions, while AMD and Palantir have appeared on the sell side of the firm’s updates.

Palantir, a Denver-based company that builds data-integration platforms used by government intelligence agencies as well as commercial customers, remains one of the most closely watched defence-adjacent software stocks. Its Gotham platform is deployed in support of analytical work by intelligence communities in the United States and the United Kingdom, among other markets.

Shares of Palantir Technologies (PLTR) traded at $170.30 in recent activity, down 2.37% from the previous close of $174.43. The company’s market capitalization stands at roughly $439.7 billion, placing it among the largest software-infrastructure names in the sector.

ARK’s decision to scale back its Palantir position comes despite the stock’s prominent place in the firm’s flagship innovation-focused funds, where it has long ranked among the largest holdings. Daily trade disclosures from ARK frequently move in small increments, and portfolio managers at the firm have previously described such sales as routine rebalancing when a single position grows too large a share of a fund.

Palantir’s valuation has expanded sharply over the past year, driven by strong growth in its commercial and government segments. That run-up has made the stock a frequent subject of debate among analysts weighing its premium multiples against its growth trajectory — a discussion that continues even as institutional holders adjust their positions.

Neither ARK’s disclosure nor the underlying trade indicates any change in Palantir’s fundamentals or its government contract base; portfolio sales of this kind reflect fund-management decisions rather than company announcements.

What to watch

  • Palantir’s next quarterly earnings report, expected to provide updated guidance on government and commercial revenue growth.
  • Further ARK Invest daily trade disclosures for additional changes to its PLTR position.
  • Any new Palantir government or commercial contract announcements, which the company typically discloses publicly.
  • Upcoming index and institutional ownership filings that will show broader fund positioning in the stock.
