The source material provided does not contain any information about a transaction between Instacart and Doordash. The passages concern a content licensing deal between Anthropic and the Associated Press, and briefly mention a potential bid by Savage Ventures for OpenWeb. No facts about an Instacart–Doordash merger, the reported $17,000,000,000 purchase consideration, or the announced deal stage appear in these sources.
I cannot write the article from this evidence without inventing details, which the rules prohibit. Please supply source passages that actually report the Instacart–Doordash transaction, and I will write the article from those.
