The revenue gap between AppLovin and Fastly has grown into a defining story within the tech sector, with the two companies on markedly different financial trajectories.
AppLovin (NASDAQ: APP) provides specialized software infrastructure designed to help mobile application developers market their creations efficiently, optimize their ad campaigns, and generate consistent advertising income worldwide.
Fastly (NASDAQ: FSLY) offers an advanced edge cloud computing infrastructure designed to efficiently manage, distribute, and secure digital applications for a wide array of clients across global markets.
Over the last eight quarters, AppLovin has experienced substantial quarter-over-quarter revenue expansion, while Fastly has maintained a much slower, more stable growth trend without major fluctuations.
AppLovin’s revenue climbed from $711.0 million in Q2 2024 to $1.8 billion by Q1 2026, demonstrating consistent and rapid upward momentum across every reporting period.
Fastly’s revenue grew more modestly over the same stretch, rising from $132.4 million in Q2 2024 to $173.0 million in Q1 2026, reflecting steady but unspectacular expansion.
AppLovin reported a net income margin of 65% for the quarter ended March 31, 2026, while also launching a new social networking application called Gist alongside ongoing regulatory inquiries.
Fastly recorded a net income margin of -12% for the quarter ended March 31, 2026, while opening a new data center facility in West Florida and addressing a performance incident in Tokyo.
AppLovin’s Q1 2026 revenue skyrocketed a whopping 59% year over year, underscoring the deeply lucrative nature of the mobile advertising market it operates within.
Fastly’s Q1 2026 sales represented year-over-year growth of 20%, yet its stock fell in May after it forecasted 2026 full-year sales between $710 million and $725 million.
If Fastly reached the top of that range, it would represent approximately 16% year-over-year growth over 2025 revenue of $624 million, a pace that failed to impress Wall Street investors.
AppLovin expects its Q2 2026 sales to continue growing, forecasting approximately $1.9 billion, extending its remarkable streak of quarter-over-quarter revenue increases.
The valuation gap between the two companies is significant, with AppLovin trading at a price-to-sales ratio of 28 compared to Fastly’s much lower sales multiple of four.
Fastly has not been without its own achievements, recording a record first-quarter gross margin of 62.5%, driven by its steady expansion through high-margin products and services.
Investors should watch whether the revenue gap between the two companies continues to widen rapidly or if AppLovin’s growth rate begins to moderate in upcoming quarters.
