- Ark Invest boosts Coinbase and Tempus AI holdings while selling Bitcoin ETF shares.
- Ark’s rebalancing strategy includes key buys in AI, healthcare, and crypto sectors.
- Ark Invest sells Bitcoin ETF and defense stocks, focusing on high-growth opportunities.
The investment firm Ark Invest, under the leadership of Cathie Wood, conducted significant trading activity in its exchange-traded funds on March 3rd, 2025. The firm invested $8 million by purchasing 38,865 shares in Coinbase Global Inc. (COIN) for its Next Generation Internet ETF (ARKW). Through this recent strategic action, Ark continues to show its dedication toward cryptocurrency assets despite fluctuating markets. The corporation distributed 95,769 shares of its ARK 21Shares Bitcoin ETF (ARKB) for $8.2 million in its diversified investment approach.
These transactions align with Ark’s approach to rebalancing its funds ensuring no holding exceeds 10% of any fund’s portfolio. Coinbase now ranks as the sixth-largest holding in ARKW, with a 6% weighting and a market value of about $99.1 million as of March 3. Despite the sale ARKB remains the top allocation in ARKW, holding a 10.3% weighting valued at roughly $169.8 million.
Ark Invest’s Focus on Fintech and Technology Stocks
Ark Invest also strengthened its position in fintech and technology sectors. The firm acquired 74,111 shares of Airbnb Inc. (ABNB) for its Fintech Innovation ETF (ARKF), with the trade valued at around $10.45 million based on Monday’s closing price of $140.98. The acquisition comes after Airbnb achieved strong performance in its fourth quarter through enhanced bookings and increased market capture from traditional hotels.
Ark acquired 9,100 shares of Tempus AI Inc. (TEM) for its Innovation ETF (ARKK) and Genomic Revolution ETF (ARKG), a combined purchase of $500,082. Tempus AI’s potential growth attracts Ark as the company evaluates the market despite its reported revenue difficulties. During Q4 2024, the company demonstrated a 35.8% increase to $200.7 million. Ark’s strategic approach centers predominantly on acquiring technological and health-oriented businesses.

Market Context and Crypto Volatility
The trades occur against a backdrop of cryptocurrency market volatility. On March 3, Coinbase shares closed down 4.6% at $205.75, reflecting a nearly 20% year-to-date decline. Bitcoin and other cryptocurrencies retraced gains from President Trump’s announcement of a U.S. Crypto Strategic Reserve, due to concerns over new tariffs on Canada, Mexico, and China. Despite Ark’s ARKB sale, the ETF saw $58.2 million in net inflows on March 3, making it the only U.S. spot Bitcoin ETF to attract inflows that day.
While other crypto markets are uncertain, going down by 11% in the last day, Ark has made changes. Coincident with Ark, these moves indicate Ark’s active management approach, with exposure to high-growth sectors and movement with the market.
