Cathie Wood's ARK Sells Chip Giants, Buys The Dip In Crypto Exchange Bullish And Two Others

• On Thursday and Friday, Cathie Wood’s ARK Invest aggressively bought Bullish shares, purchasing more than 164,000 shares of Bullish across ARKK, ARKW, and ARKF.
• The firm also cut two large semiconductor names, selling 2,131 shares of Taiwan Semiconductor on Thursday and 1,859 shares of Advanced Micro Devices on Friday, both from the ARKW fund.
• In its first large bet on Nvidia rival Cerebras Systems, ARK bought 38,646 shares for ARKK and 3,480 for ARKW on Friday.

Cathie Wood’s ARK Invest rebalanced its actively managed exchange-traded funds on two consecutive days this week, cutting positions in two of the world’s largest semiconductor names while adding to positions in crypto exchange Bullish (BLSH). 

The firm purchased 99,580 shares of BLSH for its flagship ARK Innovation ETF (ARKK), which accounts for 0.06% of the fund. ARK also increased its stake in BLSH by 27,057 shares in the ARK Next Generation Internet ETF (ARKW) and by 12,480 shares in the ARK Fintech Innovation ETF (ARKF), with both stakes accounting for about 0.056% of each fund.

The buying binge was among the largest one-day allocations by ARK to a crypto-related equity, reinforcing Wood’s long-standing thesis on digital asset infrastructure and exchanges. ARK sold 2,131 shares of Taiwan Semiconductor Manufacturing (TSM) from ARKW, representing 0.05% of the fund. 

ARK continued its Bullish accumulation on Friday, buying another 17,974 BLSH shares for ARKK, 4,829 shares for ARKW, and 2,226 shares for ARKF. The two-day total for all three ETFs topped 164,000 shares.

BLSH stock was up over 0.06% in after-hours. The stock hit its monthly low on Friday despite active purchases by Ark Invest. On Stocktwits, retail sentiment around BLSH remained in the ‘bullish’ zone, while chatter stayed at ‘high’ levels over the past day.

ARK Bets On Nvidia Rival Cerebras, Boosts Twist Bioscience Stake

ARK also began a new position in Cerebras Systems (CBRS) during Friday's session, the wafer-scale AI chip maker that recently went public. ARKK also bought 38,646 shares of CBRS for ARKK, or 0.16% of the fund, and an additional 3,480 shares for ARKW. The purchases are among the first big bets that ARK has made on an Nvidia (NVDA) rival.

The firm also raised its stake in Twist Bioscience (TWST), buying 105,810 shares in ARKK, the largest single-stock buy by share count across the two days. On the sell side, ARK sold 1,859 shares of Advanced Micro Devices (AMD) from ARKW, or 0.05% of the fund. The sale comes as AMD continues its battle with Nvidia for dominance in the AI accelerator market.
