Oppenheimer upgrades Fastly as agentic AI drives growth, stock rockets 16%

Fastly shares surged nearly 16% on Friday after Oppenheimer upgraded the edge cloud platform provider, citing growing contract values and early monetisation of agentic AI traffic. The brokerage expects these trends to sustain stronger growth over the next few years, driving the stock to a higher valuation as Fastly delivers growth and margin expansion. Oppenheimer's industry checks indicated higher contract values alongside early monetisation of traffic from agentic AI applications. The firm believes these trends could drive growth in the high teens to low 20s over the next few years. Fastly's second-quarter revenue grew 23% to $183.3 million, with security revenue up 43% to $41.7 million. The company is scheduled to report third-quarter earnings on 4 November.

Comcast and Fastly deploy edge computing to boost Peacock's live sports streaming quality

Comcast and Fastly have partnered with NBCUniversal to improve streaming quality for Peacock's live sports events by moving content closer to viewers. The collaboration runs Fastly's content delivery software directly on Comcast's distributed network of over 200 edge computing centres across the US. The approach addresses the massive infrastructure demands of live sports streaming, where millions of viewers arrive simultaneously. By processing content within Comcast's network rather than from centralised external locations, the system reduces duplicate traffic and delivery distances. The model particularly benefits major sporting events on Peacock, including NFL, NBA, and MLB games. Beyond live streaming, the underlying technology could support gaming, cybersecurity, AI inference, and enterprise cloud services. Comcast continues exploring additional applications for its edge computing resources.
