Ark Invest, led by Cathie Wood (Catherine D. Wood), bought about $37.4 million worth of shares in payments and fintech company Block. With the big purchase coming on a day Block shares fell, some analysis points to improved recent results and an investment view tied to bitcoin and digital asset businesses.

On Sept. 1 (local time), blockchain outlet Decrypt reported Ark Invest bought 456,059 Block shares on Aug. 31 and split them among 3 exchange-traded funds (ETFs).

Block trades under the ticker symbol 'XYZ'. Of the shares bought, 191,732 were allocated to the ARK Innovation ETF, worth about $15.7 million. The ARK Next Generation Internet ETF received 88,065 shares, worth about $7.2 million. The ARK Fintech Innovation ETF took 176,262 shares, worth about $14.5 million.

The timing drew attention. Block shares fell 3.23 percent to close at $80.20 on Aug. 31, but Ark Invest increased its weighting in Block that day.

The purchase is seen as an investment that considers both Block’s improving results and exposure to its bitcoin business. Block is a company Jack Dorsey co-founded in 2009, and its former name was Square. Block currently runs the merchant payment service Square and the financial app Cash App, as well as a bitcoin mining hardware business. Co-founder Jack Dorsey is known as a leading bitcoin supporter.

Results also improved. Block said second-quarter gross profit rose 25 percent from a year earlier to $3.17 billion. The company also raised its 2026 full-year gross profit forecast to $12.51 billion. That represents 21 percent growth from the previous year. Second-quarter operating profit was $447 million, and adjusted operating profit came to $864 million.

Block also highlighted development efficiency using artificial intelligence (AI). The company said nearly all production code changes in June were written and reviewed with AI’s help.

Efforts to improve the cost structure are also continuing. Since restructuring in February, Block cut its total workforce from more than 10,000 to less than 6,000.

Ark Invest also invested in stablecoin-related shares the same day, not only Block. Ark Invest’s fintech fund bought 35,192 shares of Circle Internet Group, the issuer of USDC, for about $3.36 million. Circle shares rose 9.65 percent to close at $95.55 that day.

Ark Invest, meanwhile, partially sold shares of Palantir, Shopify, Roblox, AMD and Tempus AI that day. It was not disclosed whether the proceeds from those sales were used directly to buy Block and Circle.

The market is watching whether the trades show Ark Invest’s portfolio moving back toward digital asset-related finance such as bitcoin, payment infrastructure and stablecoins. Block is directly involved in a bitcoin business while being based on payment and financial services, and some interpretation holds Ark Invest is betting again at the intersection of fintech and digital assets.

The next focus is whether Ark Invest will make additional purchases of Block and Circle. With both companies pursuing businesses that connect the traditional financial system with the digital asset market, there is a view that Ark Invest’s follow-on trades could be a signal of investment direction for related sectors.
