Software ETF Drops 4.2% as Atlassian Falls 8.6% and Circle Sinks 20%
iShares Expanded Tech-Software Sector ETF constituents slumped 4.2% as Claude’s browser-based AI release coincided with Atlassian shares falling 8.6%, Salesforce down 6%, and Adobe/SAP each down 4%. A mix of headwinds—slowing Atlassian partner tracking, rising 10-year yields, Circle’s 20% collapse on stablecoin bill concerns and AWS AI-related layoffs—added to sector pressure.
1. Major ETF and Stock Moves
The iShares Expanded Tech-Software Sector ETF fell 4.2%, with Atlassian down 8.6%, Salesforce off 6%, Adobe and SAP each down 4%, ServiceNow down 5% and Microsoft slipping 3%. This broad sell-off highlights investor caution over near-term software growth prospects.
2. Claude’s Browser AI Release
Mizuho’s Daniel O’Regan cited the launch of Claude’s new browser-based AI task feature as a catalyst for selling, arguing that easier access to on-device AI may dilute enterprise software demand and pressure valuations across the group.
3. Compound Sector Headwinds
Additional factors weighed on the pullback: a negative update on Atlassian partner performance and decelerating CY26 growth, an Anthropic usage report showing productivity gaps between expert and novice users, and 10-year Treasury yields hitting eight-month highs, raising discount rate concerns.
4. Circle Collapse and AWS Layoffs
Circle shares plunged 20% after proposed stablecoin legislation would ban yield offerings, undermining its fintech business model. Concurrently, recent AWS layoffs tied to AI agent deployments in sales and business functions underscored tech firms’ cost-cutting and automation shifts.
