POLITICO Playbook directly supports the core claim: Trump purchased $1M-$5M in Broadcom, Meta, Amazon, Apple, Microsoft, and Nvidia on the same day the White House launched its AI Action Plan, which benefited those firms. NBC News corroborates the value bands and specific names via OGE financial disclosures. The specific date of July 23, 2025 is not explicitly confirmed in the provided source summaries, and the 'benefited those companies' framing is attributed to the post rather than independently verified, which limits confidence.
