The Dow Jones rose 0.15% to 52,978 points, the S&P 500 gained 0.41% to 7,513, and the Nasdaq climbed 0.58% to 25,982. Trump highlighted the new "Trump Accounts" program for children’s investment accounts, which has attracted more than six million families.

Concerns were amplified by a Reuters report that China’s DeepSeek is developing its own AI chip, threatening Nvidia’s dominance; Nvidia’s shares dropped more than 2%. Investors also awaited U.S. trade‑deficit data and upcoming Federal Reserve minutes.
