Nvidia Becomes First Company to Reach $5.5 Trillion Market Capitalization

The brief market update states that Nvidia reached a $5.5 trillion valuation, marking a record milestone for a publicly traded company.

Fact Check
The claim is strongly supported by multiple independent and semi-authoritative sources. The Kobeissi Letter (a credible financial newsletter on X) posted a breaking news confirmation at 13:39 UTC on May 13, 2026, consistent with the collection timestamp of 14:31 UTC. WatcherGuru's original post (the linked source in the task) also directly states the milestone. CNBC's April 24, 2026 report that Nvidia's market cap had already surpassed $5 trillion provides a credible financial trajectory supporting the $5.5 trillion figure approximately three weeks later. Dozens of retweets and independent posts corroborate the event in real time. The 'first company in history' characterization is consistent with prior reporting that Nvidia was the first to reach $5 trillion in October 2025. No credible conflicting sources were found. Minor uncertainty remains because no primary financial data source (e.g., Bloomberg terminal, official exchange data) was directly retrieved to confirm the exact intraday market cap figure.
Summary

Nvidia is reported to have become the first company in history to reach a $5.5 trillion market capitalization.
