Financial news feed benchmark

We polled 43 public financial-news RSS/Atom endpoints and measured how fast each one actually publishes. 35 had enough dated items to measure. Last run 2026-08-13 17:46 UTC.

What is measured

• Items/day — publishing rate across the most recent items in the feed.
• Cadence — average time between consecutive items in that window.
• Freshness — age of the newest item at the moment we polled.
• Fetch — median time to retrieve the feed document (2 pulls).

This is feed publication cadence and transport latency. It is not event-to-headline latency — measuring that needs a known event timestamp, which RSS does not give you. No claim here goes beyond what the feeds themselves report.

Ranked by publishing rate

Method

Each endpoint fetched twice with a 300 ms gap; fetch time is the median. Items parsed from RSS <item> and Atom <entry> elements, dates from pubDate/published/updated. Rate is computed over the most recent 11 items only — using the whole feed lets one ancient item crush the average, and a bare median gap breaks when a source batch-publishes on identical timestamps. Sources with fewer than 5 dated items are dropped rather than guessed at. 8 endpoints were dropped this run (timeouts, 403/404, or too few dated items).
