Ark Invest bought $21 million in Block shares and added a $2.3 million stake in SpaceX on Thursday, according to the firm's daily trading disclosure. The purchases sit at the intersection of bitcoin and Elon Musk's business empire — Block has built its treasury around the asset, and SpaceX is Musk's privately held rocket company.
The two trades
Block is the bigger buy. Ark's $21 million position adds to a holding the firm has accumulated over years as part of its fintech-and-crypto thesis. The SpaceX purchase is smaller but carries its own weight: stakes in private companies are harder to source, and Ark has been building exposure through vehicles that trade in the secondary market.
Both moves landed in the same daily report, which Ark publishes every session. That report is the window into how Cathie Wood and her team are repositioning — and Thursday's version shows money flowing into two companies tied to the same broad bet on digital assets.
Why bitcoin ties them together
Block, the payments firm formerly known as Square, has made bitcoin central to its strategy. The company holds the asset on its balance sheet and has built products around it. Musk, for his part, has kept SpaceX and his other ventures in the crypto conversation, and his companies have at times held or transacted in digital assets.
For Ark, the two trades read as one thesis: infrastructure and adoption. Block covers the payments rail, SpaceX covers the frontier of Musk's operations. Wood has talked for years about bitcoin as a monetary network and innovation asset, and these buys fit that framing.
An open book
Ark's daily trading disclosures are unusual in the asset management business. Most firms report positions quarterly, with a lag. Ark shows its hand every day, and investors have learned to read those filings for signals about where Wood thinks the market is heading.
Thursday's report is a straightforward signal: Ark is still buying into the crypto-adjacent names it has championed, even as the broader market digests a busy stretch of news.
The next daily disclosure will show whether these positions grow or get trimmed. Ark doesn't signal its next move in advance — it just publishes the trades.
