June 16 (Reuters) - U.S. stock index futures were subdued on

Tuesday as investors switched focus to the first interest rate

decision under new Federal Reserve Chairman Kevin Warsh, while

SpaceX extended its post-IPO run for a third day.

Tech stocks were a bright spot in premarket trading, with

shares of SpaceX climbing 10%, putting the space and AI

giant on course to overtake Amazon ( AMZN ) in market value and

become the world's fifth-largest company.

Memory chip stocks also jumped, with Micron Technology ( MU )

, Western Digital ( WDC ) and Seagate Technology ( STX )

rising between 2.9% and 4.8%.

The blue-chip Dow closed at a record high on Monday

after U.S. President Donald Trump said a preliminary agreement

to end the conflict had been signed by the U.S. and Iran,

sending oil prices sharply lower and easing concerns about

inflation.

Still, doubts swirled around the deal as shippers said it

could take weeks for confidence to return after any reopening of

the Strait of Hormuz.

The Fed is widely expected to hold interest rates at the

3.50-3.75% range at the end of its policy meeting on Wednesday,

with investors closely watching Warsh's comments on inflation,

unemployment and the economic outlook, potentially market-moving

words of the world's most important central banker.

Inflation, in particular, seems stuck more than a percentage

point above the Fed's 2% target, and Warsh's characterization

about whether and when it is likely to fall will be a key first

step in the evolution of monetary policy under his leadership.

Traders see a 42% chance of a 25-basis-point rate hike in

December, as per CME Group's FedWatch tool, with rate cuts seen

coming only after mid-2027.

The Bank of Japan raised interest rates to a 31-year high

earlier on Tuesday, as it focused on taming price pressures from

the energy shock caused by the Iran war.

At 5:58 a.m. ET, S&P 500 e-minis were down 6 points,

or 0.08%. Nasdaq 100 e-minis were up 5.25 points, or

0.02%, and Dow e-minis added 20 points, or 0.04%.

The benchmark S&P 500 was also closing in on early

June record highs after a slump driven by concerns about high

valuations in the technology sector and the U.S.-Iran conflict.

Qualcomm ( QCOM ) rose 3.8% after the Information reported

that the chipmaker was in talks to acquire AI chip startup

Tenstorrent for $8 billion to $10 billion.

Shares of Dave & Buster's Entertainment fell 13.3%

after the entertainment firm missed analysts' expectations for

first-quarter earnings and revenue.
