The U.S. stock market has never been higher, even though the list of challenges chipping away at it keeps growing.

The S&P 500 climbed 0.6% Tuesday to a record after topping its prior all-time high set in August.

The Dow Jones industrial average added 253 points, or 0.5%, while the Nasdaq composite tacked 0.4% onto its own all-time high set the day before.

AI stocks have been a huge force driving the U.S. market to records, including Nvidia’s 28.3% surge so far this year. That’s roughly double the broad market’s gain.

Constellation Energy jumped 12.2% for one of Tuesday’s biggest gains in the S&P 500. It announced a long-term deal to supply Google with about as much electricity as a new nuclear reactor makes.

Elsewhere on Wall Street, Option Care Health soared 32.6% after CD&R and McKesson said they’re buying the provider of infusion services. The two are paying $32.05 for each Option Care Health share, valuing it at roughly $5.8 billion.

All told, the S&P 500 rose 44.98 points to 7,818.93. The Dow added 253.38 to 51,521.28, and the Nasdaq composite climbed 122.48 to 27,599.79.
