On May 21, 2025, Nvidia Corp. (NVDA) named a partner for its new 800-volt data center architecture.

For Navitas Semiconductor Corp. (NVTS), a small power-chip maker, it was the most important day in the company’s history. Shares spiked more than 180% in a single session.

Two completely different outcomes for the same press release.
