- Block delivered Q2 revenue of $6.62 billion, representing 9% annual growth, while adjusted earnings per share reached $1.02, surging 65%.
- Mizuho analysts warned that operational costs are projected to climb from $4.48 billion in the first half to $4.56 billion in the second half.

Shares of Block ended Thursday’s session at $79, reflecting a 6.15% decline, as investors digested the company’s second-quarter financial results that spotlighted cost structure challenges.
The downturn didn’t discourage Cathie Wood from adding to her position. Her investment firm, Ark Invest, purchased 267,676 shares of Block distributed across three exchange-traded funds during the same trading session that saw the stock retreat.
The aggregate acquisition amounted to roughly $21 million. Within Ark’s ARKW ETF, Block represents the 10th-largest position, valued at approximately $60 million and accounting for 3.51% of the fund’s total holdings.
Ark’s investment framework limits individual positions to a maximum of 10% of any fund’s total assets, maintaining portfolio balance and risk management.
Block’s second-quarter performance showed strength across several metrics. The company posted revenue of $6.62 billion, marking a 9% increase from the prior year and surpassing analyst projections.
Adjusted earnings per share reached $1.02, representing a robust 65% annual increase. Gross profit expanded 25% to $3.17 billion.
Rising Expense Trajectory
Beyond the positive top-line figures, Mizuho analysts identified a troubling trend: operational expenses continue their upward trajectory, despite Block implementing significant workforce reductions of 40% earlier in February.
According to Mizuho’s analysis, adjusted operating costs are expected to increase from $4.48 billion during the year’s first six months to $4.56 billion in the latter half, based on company-provided guidance.
This widening disconnect between impressive revenue momentum and escalating operational spending triggered Thursday’s share price decline.
Additional Thursday Portfolio Activity
Beyond the Block acquisition, Ark executed numerous portfolio adjustments on Thursday. The firm divested 117,172 shares of Shopify across ARKK, ARKW, and ARKF, representing $16.9 million in total value. This transaction extends Ark’s ongoing strategy of reducing its Shopify exposure throughout the week.
On the acquisition front, Ark accumulated 239,907 shares of MercadoLibre through ARKW, valued at $4.6 million.
Within the biotechnology sector, Ark purchased 422,198 shares of Intellia Therapeutics distributed between ARKK and ARKG, totaling a $4.6 million commitment.
The firm also liquidated 23,907 shares of Palantir across several ETFs for $3.79 million, while reducing its Roblox position by 65,036 shares through ARKK for $2.35 million.
Cybersecurity holdings faced additional reductions. Ark sold $2.79 million worth of Cloudflare and $2.76 million in CrowdStrike shares, scaling back exposure to both security-focused companies.
In a separate transaction, Ark acquired 20,318 shares of SpaceX valued at $2.3 million. SpaceX had experienced a 13.6% decline the previous session as investors processed news of $18.4 billion in second-quarter capital expenditures, representing a sixfold annual increase. The stock rebounded 6.14% on Thursday, finishing at $114.92.
Ark additionally sold 39,509 shares of Bullish through ARKW for $910,287. The cryptocurrency exchange declined 3.36% on Thursday, ending the session at $23.04.
Thursday’s decline to $79 represented Block’s steepest single-session loss in recent trading history, coinciding precisely with Ark’s decision to expand its stake.
