Cathie Wood’s ARK Invest made a clear statement with its semiconductor trades on Thursday, May 14, 2026. The firm sold shares in three established chip companies while buying into one of the most talked-about IPOs in recent memory.

The biggest sale was 41,540 shares of Taiwan Semiconductor, bringing in roughly $16.6 million. The trade came on a day when the stock climbed 4.4% to close at a record high of $421.97. ARK has been trimming its Taiwan Semiconductor position over several recent sessions.

ARK also sold 11,510 shares of Advanced Micro Devices for about $5.1 million. That continues a trend of reducing AMD exposure that has played out over the past week across ARK’s funds.

Teradyne was another chip-related name ARK moved away from. The firm sold 22,576 shares valued at around $8.2 million. That follows earlier selling in Teradyne, pointing to a deliberate exit from the stock.

Outside of chips, ARK sold shares in three other companies. These included 11,602 shares of Twist Bioscience for $631,032, 35,073 shares of Adaptive Biotechnologies for $460,508, and 13,525 shares of CareDx for $278,750.

ARK Jumps Into Cerebras After Record IPO Demand

On the buying side, ARK’s moves centered entirely on Cerebras Systems. The firm picked up 105,616 shares across two ETFs — the ARK Innovation ETF and the ARK Next Generation Internet ETF — for a combined $4.85 million.

Cerebras is an AI chip company known for building wafer-sized processors designed for AI inference work. The company priced its IPO at $185 per share on May 13. Demand reportedly came in at more than 20 times the available supply.

When Cerebras shares began trading publicly on May 14 under the ticker CBRS, they opened at $350. The stock closed its first day at $311, still well above the IPO price.

That first-day performance pushed Cerebras to a valuation of roughly $49 billion. The company has drawn investor attention through its ties to OpenAI and a partnership with Amazon Web Services.

What the Trades Say About ARK’s Strategy

The pattern in Thursday’s trades is straightforward. ARK sold positions in companies that have seen strong recent price appreciation, including Taiwan Semiconductor at its record high, while directing fresh capital toward a newer, higher-growth name.

This approach fits ARK’s broader track record of rotating out of stocks that have run up and into early-stage companies in fast-moving technology areas.

Cerebras fits that profile. The AI chip space has attracted heavy investment as demand for data center infrastructure grows. Cerebras sits in the middle of that trend, with real commercial relationships already in place.

The trades were disclosed through ARK’s daily fund updates, which the firm publishes after each trading session. As of the close on May 14, Cerebras had one of the strongest IPO debuts in the AI hardware space to date.
