May 6 (Reuters) - Wall Street futures climbed on

Wednesday, buoyed by hopes of a U.S.-Iran peace agreement and

unrelenting optimism around artificial intelligence.

The rally, which took the S&P 500 and the Nasdaq

Composite indexes to record highs on Tuesday, showed few

signs of easing after Advanced Micro Devices ( AMD ) forecast

second-quarter revenue above expectations, helped by robust

demand for its data-center chips.

"Wall Street continues to double down on its bet that the

war in the Middle East will not re-escalate and disrupt the

market's earnings-driven surge to all-time highs," said Kyle

Rodda, senior financial market analyst at Capital.com.

"The signals sent from the United States appear to offer

reassurance that it's not interested in renewing hostilities."

U.S. President Donald Trump said "great progress" had been

made toward a peace agreement with Iran, while Tehran said it

will only accept "a fair and comprehensive agreement."

Oil prices fell for a second consecutive day, with Brent

crude futures slipping 3.3%.

The gains reflect rising risk appetite among investors,

provided corporate earnings remain strong and hopes for a peace

deal stay alive.

But the more the stocks rise, the greater is the chance of a

pullback if the diplomatic efforts to end the Iran war derails.

At 4:43 a.m. ET, Dow E-minis rose 126 points, or

0.25%, S&P 500 E-minis gained 23.25 points, or 0.32% and

Nasdaq 100 E-minis were up 228 points, or 0.81%.

AMD jumped 18.1% in premarket trading, while rival Intel ( INTC )

rose 6.1%. Super Micro also jumped 17.7%

following a stronger-than-expected forecast for fourth-quarter

revenue and adjusted profit.

Alphabet jumped 1.4%, narrowing the gap with

Nvidia ( NVDA ) in the race to become the biggest company by

market value. Nvidia ( NVDA ) rose 0.44%.

Arm Holdings gained 11.3% ahead of its quarterly

results.
