Aug 12 (Reuters) - Wall Street's main indexes were on track

to open higher on Wednesday as investors assessed a largely

in-line inflation reading, while upbeat earnings from some AI

infrastructure companies provided additional support.

Labor Department data showed the consumer price index rose

3.4% in July from a year earlier, in keeping with the forecast

of 3.4% from economists polled by Reuters. On a monthly basis,

the CPI rose 0.1% compared with an expectation of a 0.1%

increase.

Traders are now pricing in a 55% chance the U.S. Federal

Reserve will hold rates at its September meeting, according to

CME's FedWatch Tool. Before the data, they were split between a

hike and no change.

Inflation figures have been in greater focus as elevated

energy prices stemming from the Middle East conflict ratcheted

up the odds of a rate hike.

Fed Chair Kevin Warsh's firm stance on muted forward

guidance has also meant investors focus on economic data for

clues about the central bank's policy direction.

"These backward-looking numbers kind of put the Fed in

exactly the position they want to be. They don't have to do

anything. It's the narrative they want, that we're seeing some

cooling, but there's no collapse in the economy," said Luke

Rahbari, CEO of Equity Armor Investments.

"But... we've had so many starts and stops to the war in

the Middle East and wild swings in oil and gasoline, that this

could totally change day by day."

The situation in the Middle East remained volatile as the

U.S. and Yemen's Iran-aligned Houthis reported separate attacks

on shipping on Tuesday as prospects for the war ending appeared

to dim.

At 08:52 a.m. ET, Dow E-minis rose 136 points, or

0.25%, S&P 500 E-minis gained 33 points, or 0.43%, and

Nasdaq 100 E-minis advanced 279.75 points, or 0.94%.

CoreWeave ( CRWV ) jumped 19.2% in premarket trading after

the AI cloud company lifted its annual capital spending forecast

and topped second-quarter earnings estimates.

Other AI infrastructure providers also rose, including

data-center operators IREN ( IREN ) and Applied Digital ( APLD )

, both up more than 8% each. Neocloud company Nebius

Group ( NBIS ) jumped 16.7%.

Super Micro Computer ( SMCI ) added 9.2% after the AI-server

maker forecast fiscal 2027 revenue above Wall Street

expectations.

The earnings underscore robust AI-related demand as Wall

Street giants continue to spend billions to scale up AI

infrastructure. Overall, current-quarter results have painted an

upbeat picture of corporate America, helping lift the S&P 500

and the Dow to record highs.

Most megacap and growth stocks rose on Wednesday, with

Nvidia ( NVDA ) up 1.6%.

Cava Group ( CAVA ) surged about 17.2% after the restaurant

chain beat Wall Street expectations for second-quarter sales and

core profit.
