It's Jim Kramer here. You're listening to the opening bell of CNBC Squawk on the Street.

Don't miss a minute of the action.

Good Wednesday morning. Welcome to Squawk on the Street. I'm Carl Kintanilla with Jim Kramer and David Faber at the New York Stock Exchange.

Pretty steady pre-market on this Fed day. Decision at 2 o'clock Eastern, followed by Powell's Presser.

Lots to watch, though, Saudi Aramco, Boeing, Home Depot, as we wait for clarity on China tariffs.

Europe has mixed, UK election tomorrow, and then CPI just ahead of estimates.

Core rate up 2, 3 year-on-year.

Our roadmap begins with an historic IPO.

Shares of Saudi Aramco surge 10% in its debut, now valued at nearly

$1.9 trillion, the largest listed company in the world. Plus the Fed and a trade waiting game.

Stocks are poised for a muted open as investors seek further tea leaves on trade and the fate of monetary

policy. And monopolies aren't bad if they are not abused.

Apple's Tim Cook coming to the defense of monopolies in business, but says Apple isn't one.

We'll begin with Saudi Aramco, though, a strong public debut after raising a record 25.6 billion in the IPO.

Shares jumped on the open, the maximum 10% on the stock exchange in Riyadh.

Limit up. As a result, the state-owned oil giant is the world's most valuable company listed at almost $1.9 trillion.

That's about six Exxons and above Apple, which has a market cap of almost $1.2 trillion.

Well, a well-placed deal.

Apparently, a lot of people in Saudi Arabia decided to buy the stock, and that boosted

it.

I think that they, you know, sometimes you get these deals, and they pretty much determine

where it's going to be.
