Cathie Wood’s ARK Makes Bold Moves: Buys Broadcom, Joby, Archer While Dumping $10 Million in Palantir Stock

Cathie Wood just reshuffled the deck—and Wall Street is watching.

The Big Bet on Broadcom & Flying Taxis

ARK Investment Management loaded up on semiconductor giant Broadcom and doubled down on the future of urban air mobility with fresh buys in Joby Aviation and Archer Aviation. The moves signal a continued conviction in tech infrastructure and next-gen transportation—the kind of frontier bets Wood's known for.

The $10 Million Palantir Exit

Meanwhile, ARK slashed its position in Palantir Technologies, offloading roughly $10 million worth of stock. The sale trims exposure to the data analytics firm as Wood pivots toward other disruptive themes. It’s a classic portfolio rebalance—cutting winners to fund new convictions, or maybe just locking in gains before the next earnings whisper.

Why This Trade Matters

Wood’s buys highlight a focus on enabling technologies—chips that power AI and electric aircraft that could redefine cities. The Palantir sale, though, reminds us that even high-conviction investors take profits. After all, in finance, sometimes the smartest trade is knowing when to walk away—especially before a stock’s narrative gets too, well, data-driven.

Cathie Wood’s ARK Invest made several portfolio changes on January 8, buying chip stocks and electric air taxi companies while reducing holdings in Palantir Technologies. The trades show ARK’s focus on technology and aviation sectors.

ARK’s biggest purchase was 31,573 shares of Broadcom through the ARK Next Generation Internet ETF. The purchase was worth $10.4 million. Broadcom stock fell 3.2% on January 8 during a market decline.

Broadcom Inc., AVGO

Wood also bought shares in two flying taxi companies. ARK purchased 162,270 shares of Joby Aviation through the ARK Space Exploration & Innovation ETF for $2.5 million. The purchase came after Joby bought a 700,000-square-foot manufacturing facility in Dayton, Ohio.

The facility will be used to produce electric air taxis. These aircraft are also called eVTOL aircraft. Joby stock dropped 1.9% on the day of ARK’s purchase.

ARK added 73,097 shares of Archer Aviation after the company announced a partnership with Nvidia. The deal focuses on bringing AI systems into future aircraft. Archer stock ROSE 3.4% on the news.

Wood also bought 22,395 shares of Personalis for the ARK Genomic Revolution ETF. The genomics company’s stock fell 10.4% before ARK’s purchase. This follows Wood’s recent buying pattern in the stock.

ARK Sells Palantir Stake

On the selling side, ARK dumped $10.4 million in Palantir Technologies. The fund sold 58,741 shares of the AI software company. This happened as President Donald TRUMP proposed a $1.5 trillion defense budget by 2027.

The proposed budget represents an increase from current spending levels. Palantir gets much of its revenue from government contracts for AI services. However, Palantir stock dropped 2.7% on January 8.

ARK also reduced positions in defense and space companies. The fund trimmed stakes in Aerovironment, Rocket Lab, and Kratos Defense. These sales were smaller than the Palantir transaction.

Wood separately sold $2.29 million in Roku stock on January 7. ARK offloaded 20,203 shares of the streaming platform company. This came after Roku gained 10% in the past month.

Roku posted a 42% gain in 2025. The stock outperformed the S&P 500 last year. Even after the sale, Roku remains a top holding in ARK Innovation ETF.

ARK Innovation gained nearly 38% in 2025. The fund benefited from gains in AI and software stocks. Wood’s investment approach focuses on disruptive technology companies.

The January 8 trades show Wood buying during price declines in chip and aviation stocks. She sold positions in companies that had recent gains or faced market pressure.
