Cathie Wood isn't backing away from her Bitcoin bet. On Tuesday, Ark Invest doubled down on crypto exposure by adding shares of the ARK 21Shares Bitcoin ETF (ARKB) even as Bitcoin itself keeps swinging through choppy U.S. trading sessions and investors debate whether a six-figure price tag is realistic this year.

Building the Bitcoin Position

Ark's flagship innovation funds are steadily accumulating Bitcoin-linked exposure. The ARK Blockchain & Fintech Innovation ETF (ARKF) picked up 5,754 shares of ARKB, while the ARK Next Generation Internet ETF (ARKW) bought 49,246 shares. Based on ARKB's closing price of $30.92, the combined transaction totaled $1.7 million.

The timing is notable. Recent analysis has highlighted a frustrating pattern for crypto bulls: repeated sell-offs at the start of U.S. trading sessions have been erasing earlier Bitcoin gains. Some market observers chalk this up to aggressive high-frequency trading strategies that exploit liquidity windows before reversing course, creating choppy intraday action that's made sustained rallies difficult.

But Ark appears to be looking past the short-term noise. At the time of the purchases, Bitcoin was trading 2.49% higher over 24 hours at $92,269.08 as Wall Street priced in expectations of a rate cut.

New Regulatory Framework Expands Bitcoin's Role

Meanwhile, the regulatory landscape is shifting in Bitcoin's favor. The Commodity Futures Trading Commission recently announced a new framework under Acting Chair Caroline Pham that widens Bitcoin's role inside traditional finance. Approved intermediaries can now accept major tokens and stablecoins as margin, provided they follow strict custody and reporting rules.

That's a meaningful development for institutional adoption. It signals that regulators are creating pathways for crypto to integrate more deeply into conventional financial plumbing, rather than treating it as a fringe asset class.

At the same time, crypto prediction markets now assign roughly even odds that Bitcoin can break above $100,000 before the end of 2025. So Ark is operating in a macro environment where regulatory tailwinds and expectations for Federal Reserve rate cuts are offsetting near-term volatility.

Other Portfolio Moves

Alongside the ARKB accumulation, Ark made several notable adjustments across its sector-focused funds during the same Tuesday session.

• Ark trimmed its position in Ibotta (IBTA), unloading 52,047 shares from ARKF and another 47,141 shares from ARKW.
• The firm continued reducing exposure to satellite operator Iridium Communications Inc. (IRDM), selling 23,994 shares from ARKK, 5,681 shares from ARKQ, and 1,575 shares from ARKX.
• In the genomics sleeve, ARKG offloaded 90,807 shares of Adaptive Biotechnologies Corp (ADPT) while adding 17,732 shares of Arcturus Therapeutics Holdings Inc. (ARCT) and 1,653 shares of GeneDx Holdings Corp (WGS).
• ARKQ also pared back its semiconductor testing exposure by selling 2,253 shares of Teradyne Inc. (TER), aligning with Ark's recent pattern of reallocating capital from mature hardware names to higher-growth innovation themes.

Market data indicate ARKB falters on short, medium, and long price trends, though the ETF maintains stronger performance on other parameters. That hasn't stopped Wood from adding exposure at current levels, betting that the combination of regulatory clarity, potential rate cuts, and growing institutional acceptance will eventually push Bitcoin higher despite the turbulence.
