Cathie Wood's ARK Buys $16 Million CoreWeave Dip, Trims Palantir

ARK Invest bought 283,022 shares of CoreWeave (NASDAQ: CRWV) worth roughly $16 million on Thursday, November 12, 2026 — the same day the stock fell 6.86% to $56.60. The purchase, disclosed in Cathie Wood's fund filings, marks a deliberate bet on a debt-funded AI infrastructure builder right after a sharp sell-off, and it came paired with the opposite trade: ARK sold 58,339 Palantir (NASDAQ: PLTR) shares worth about $10 million while trimming one of the AI software market's most expensive winners.

The moves matter beyond ARK's own book. They show how a prominent AI investor is now splitting the sector into two very different bets — raw compute capacity financed with heavy debt, and high-margin software trading at extreme multiples — and choosing to load up on the former at a discount.

What did ARK actually buy and sell?

Both trades ran through the ARK Innovation ETF (BATS: ARKK) and a sister internet fund. The November 12 holdings file for ARKK shows about 2,431,528 CoreWeave shares, or 2.37% of the fund, and about 948,590 Palantir shares, or 2.63%.

The Palantir sale wasn't a standalone verdict. On the same day, ARK also bought about $8.9 million of Twist Bioscience (NASDAQ: TWST) and sold pieces of several other holdings, so the Palantir trade was one part of a wider rotation. Palantir remains one of ARKK's larger positions, which makes the sale a trim rather than an exit.

ARK has not said why it made the trades. The pattern speaks for itself: it added to a debt-funded AI infrastructure builder after a decline and reduced an AI software winner that trades at a premium price.

Why was CoreWeave falling in the first place?

CoreWeave reported third-quarter results on November 10 and closed that day at $48.73. On November 11, the stock surged 24.71% to $60.77. On November 12, it fell as low as $50.17 before closing at $56.60. That close still sits above the pre-earnings level, but the stock was down 27.26% for the month through November 12.

Two reasons were reported for the slide:

• Soft guidance from a rival, an AI-focused cloud provider called Neocloud.
• Doubt about support from NVIDIA (NASDAQ: NVDA) after Jensen Huang resigned as its CEO.

NVIDIA invested $2 billion in CoreWeave stock in January 2026, so the leadership change feeds directly into questions about how durable that relationship is. CoreWeave's CEO said he saw "no reason" for the partnership to change — but he said it on November 11, before Huang left. That timing leaves the reassurance untested.

How big is each business behind the trade?

CoreWeave is valued at about $25.97 billion. Its third-quarter revenue grew 168% to $3.66 billion, and its backlog stands at $132.5 billion. The company plans $37 billion to $39 billion of capital spending and lost $709 million in the quarter, which included $846 million of net interest expense.

The backlog locks in future revenue. It does nothing to address the cost of financing all that spending, or how much CoreWeave depends on a few buyers — its top customer generated about 67% of 2025 revenue.

Palantir is a different animal. It is valued at about $395.78 billion, with a debt-to-equity ratio of 0.03, a net margin of 36.3%, and third-quarter revenue up 95.9% to $2.313 billion. The cost of that quality is a price of about 244 times earnings.

What are analysts saying?

On November 12, Barclays cut its CoreWeave price target to $85 from $105, and Argus cut its target to $100 from $150. Both targets remain well above the share price, so neither firm is calling the story off.

The timing is the telling part. Analysts cut those targets right after a quarter that beat estimates, which suggests they now see more financing risk in the name than they did before.

What risks should investors weigh?

For investors near retirement, the source flags significant risk in CoreWeave. The company carries heavy debt, and it has an at-the-market program — new shares sold gradually into the market — of up to 35 million shares that could dilute existing holders. Its key supplier, NVIDIA, also now has new leadership.

ARK itself holds CoreWeave at 2.37% of ARKK. That's small enough for a high-risk fund to absorb if the investment goes wrong.

Palantir has the stronger financial profile, even though ARK reduced it. The company expects $4.8 billion to $5.0 billion of adjusted free cash flow for 2026, and its 17.77% drop through November 12 has cut the price investors pay for that growth.

What comes next?

Watch NVIDIA's earnings report on November 17. If CoreWeave ends below $48.73 after that report, it will have given back its entire post-earnings rally — and that would point to deeper concern about its financing. If it closes back above $60.77, the November 12 drop was probably just noise.
