Cathie Wood remains an anomaly in the investment sphere, treating stocks as long-term “technological revolutions” rather than quarterly trades.
The fund manager buys and sells
Through ARK Invest, he runs a concentrated, high-conviction portfolio spanning disruptive themes, including areas such as artificial intelligence, robotics and cryptography.
A big part of the reason investors follow it closely is because of its transparency.
He posts his trades daily and isn’t afraid to lean into volatility.
Perhaps your best bets include backing Tesla, pioneer of electric vehicles in 2016, long before the company reached cruising altitude or captured the investor zeitgeist with robotaxis and Optimus robots.

So far in 2025, its flagship ARK Innovation ETF is up nearly 55% to 60% so far this year, compared to nearly 13% for the S&P 500 in terms of total return.
In other words, Wood’s flagship fund is outperforming the broader market more than 4x this year.
Now, the ARK Invest boss is buying CoreWeave’s dip.
she picked up 350,734 sharesspending almost $24 million as the stock fell almost 30% in recent trading sessions.

It has tiptoed back into Nvidia, adding more shares for the first time since August. she picked up 93,374 shares from the chip giant ($17 million worth). While not a huge position, it is a clear re-entry into the name that defines AI trading.
Overall, Wood remains a fan of AI and boldly stated on CNBC in October that while there could be fixes, there are still more opportunities:
Meanwhile, CoreWeave’s gains tested investors’ patience.

It’s a timing headache, not a demand problem: The downgrade is apparently due to a delay at a single third-party data center developer (reportedly CoreScientific), which pushed some Q4 2025 GPU capacity and sales into early 2026. Meanwhile, the The sales portfolio skyrocketed to $55.6 billion, representing a quarter-on-quarter increase of 85%.
CoreWeave for rent Nvidia-powered data centers to hyperscalers and other tech companies to build AI models. So it’s essentially renting GPU power to companies that avoid the costs of running their own hardware.
It’s basically a power grid for AI, where companies can simply connect and pay for your use.
Furthermore, it is a factory floor cloud where CoreWeave provides the heavy machinery (GPU, networks, infrastructure), while its clients provide their plans (models) and data.

Furthermore, the two AI giants also have a $6.3 billion “take or pay” cloud capacity agreement that will extend until 2032.
Nvidia CEO Jensen Huang even publicly noted that his stake in CoreWeave is the type of “big startup” the tech giant backs within its AI infrastructure ecosystem.
Wood didn’t stop at CoreWeave. It also expanded bets on crypto and biotechnology.
ARK added 49,900 Bullish sharesa popular public crypto exchange that owns CoinDesk. In addition, it has been one of the most striking debuts of 2025, with a huge $1.1 billion IPO and a Valuation of $5.4 billion.
Wood combined that with 31,890 BitMine shares and 20,700 shares of the ARK 21Shares Bitcoin ETFeven as Bitcoin fell below $85,000its weakest level since April.
Additionally, ARK bought 67,078 shares of CRISPR Therapeuticsa $3.3 million nod to his long-held belief that gene editing is the next chapter of medicine.
