AI Market Summaries With Stale Data: How to Detect Unsupported Claims

An AI summary can describe yesterday's market in today's tense. Timestamps and tool calls reveal stale or unsupported claims.

Short answer

Detect stale or unsupported claims in AI market summaries by checking: whether each number has a timestamp, whether that timestamp is recent enough for the claim, whether a tool call fetched it (rather than the model recalling it), whether present-tense statements ('funding is high') match current data, and whether the summary mentions events you can't find. Ask the agent to timestamp every value and to say explicitly when data could not be retrieved.

Example

Illustrative: a summary says 'funding is elevated at +0.04%'. The tool call shows the value was fetched 30 hours earlier; current funding is +0.008%. The claim was true yesterday and misleading today.

A two-minute routine

Before acting on any AI summary: highlight every number and event, check that each has a timestamp within your decision window, open the tool call or source for the two most important ones, and re-fetch them. If anything is stale or unsupported, ask the agent to redo the summary with current data.

Conclusion

Require timestamps and sources for every claim in AI summaries, and re-fetch anything stated in the present tense.
