In November, Musk asked a federal court to block OpenAI from converting to a for-profit entity.

[PRO] Eyes on rates and prices
Interest rates and inflation are in focus this week. The U.S. Federal Reserve's rate-setting meeting ends Wednesday, while the personal consumption expenditures price index, the Fed's preferred gauge of inflation because it reflects how consumers actually spend money, comes out on Friday.

The bottom line

A near-surefire of figuring out where markets are heading is to make a prediction — and disregard it.

The S&P 500 may have slipped 0.6% last week, snapping its three-week winning streak. But it's still up almost 27% this year, shattering the 6,000 level for the first time on its journey upward.

That's way ahead of forecasts made by top financial strategists at the end of 2023, notes CNBC's Pia Singh. JPMorgan's chief U.S. equity strategist, Dubravko Lakos-Bujas, for instance, expected the broad-based index to close the year at just 4,200. Even the most optimistic prediction — a 5,200 target from John Stoltzfus, chief investment strategist at Oppenheimer — didn't capture the exuberant stock rally this year.

And that's why even though market strategists anticipate the S&P to finish 2025 at 6,630, according to the average forecast from the CNBC Market Strategist Survey, investors should take it with a pinch of salt. Granted, there's positive sentiment bubbling among investors, thanks to Trump's high regard for the stock market as a barometer for his presidential tenure, steadily loosening monetary policy, the prospect of lower corporate taxes, among other factors. But, in markets — as in life — the best laid plans of mice and men often go awry.

Inflation might make an unwelcome return — like measles and possibly polio in the U.S. — because of Trump's promised tariffs and the tit-for-tat trade wars that could ensue. Indeed, inflation already "looks a little stuck," said Goldman Sachs' vice chairman Robert Kaplan, previously president of the Dallas Fed.

Still, despite my skepticism of predictions, I'd love it if Bank of America's Savita Subramanian proves to be a prescient market forecaster. Imagine ending 2025 with the S&P at Subramanian's target of 6,666.
