What Happened?
A number of stocks jumped in the afternoon session after shares across the enterprise software, cybersecurity, and cloud infrastructure sectors caught a massive bid in Tuesday's premarket session. The rally was ignited by a blockbuster earnings report from data analytics giant Palantir (NYSE: PLTR), whose stock skyrocketed over 26%, acting as a rising tide that lifted dozens of high-growth tech peers—ranging from data players like Snowflake and Datadog to cybersecurity leaders like CrowdStrike and Palo Alto Networks.
The primary catalyst for the sector-wide surge was Palantir’s exceptional second-quarter print and upwardly revised full-year revenue outlook. Citing unprecedented demand for its Artificial Intelligence Platform (AIP), Palantir posted explosive growth in both its core U.S. commercial business and government contracting segments. By explicitly demonstrating that enterprise customers are aggressively deploying—and paying for—advanced AI capabilities, Palantir extinguished lingering market fears that the AI boom was merely infrastructure hype without near-term software monetization.
Beyond Palantir's blowout quarter, this "risk-on" environment was heavily turbocharged by shifting macroeconomic and geopolitical winds. News that the U.S. and Gulf allies are shifting toward diplomatic talks to reopen the Strait of Hormuz effectively de-escalated fears of a broader Middle East conflict. This geopolitical relief valve caused a sharp pullback in oil prices and inflation expectations, driving Treasury yields lower. For software companies—whose valuations are highly sensitive to borrowing costs and the discount rates applied to future cash flows—this sudden drop in rates provided the perfect macro tailwind. Together, the combination of lower yields and definitive proof of AI monetization sparked an aggressive premarket rotation back into growth-oriented tech equities.

Zooming In On Fastly (FSLY)
Fastly’s shares are extremely volatile and have had 61 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.
The previous big move we wrote about was 11 days ago when the stock gained 3.7% on the news that the company joined Experian's Agent Trust™ ecosystem to help businesses verify AI agents and authorize transactions in real time. The collaboration with Experian, a global information services company, aims to enhance security and trust as autonomous commerce, or AI-driven transactions, continues to grow. By integrating with Experian's system, Fastly, a global edge cloud platform, is positioned as a key player in the infrastructure for secure AI commerce. This news prompted a positive investor reaction, with traders seeing the move as strengthening Fastly's role in AI-focused infrastructure and its strategic position in edge computing.
Fastly is up 144% since the beginning of the year, but at $24.85 per share, it is still trading 25.8% below its 52-week high of $33.50 from April 2026. Despite the year-to-date gain, investors who bought $1,000 worth of Fastly’s shares 5 years ago would now be looking at only $557.93.
