July 10 (Reuters) - The Standard & Poor's 500 index rose to close on Friday near its record high, as the stunning listing of South Korea's SK Hynix on the Nasdaq Composite boosted optimism about chipmakers as investors await the start of next week's quarterly earnings season.

AI stocks returned to the spotlight after SK Hynix shares opened 14 percent above their IPO price of $170 in a major US listing. The semiconductor company raised more than $26 billion on Thursday by selling American Depositary Receipts (ADRs) at $149 each.

U.S. stocks extended their gains after U.S. President Donald Trump said Iran had asked to continue talks and the United States had agreed, but the ceasefire reached in June was "over".

The tit-for-tat attacks between the United States and Iran this week renewed concerns that high energy prices could exacerbate inflation and force the Federal Reserve (the US central bank) to raise interest rates.

The London Stock Exchange Group notes that reports from major US banks will kick off the second-quarter earnings season next week. Analysts expect the S&P 500 to rise 24 percent year-on-year, with technology companies driving much of that growth.

"This is a high-standard, narrow-margin quarter," said Terry Sandphin, senior equity strategist at U.S. Bank Wealth Management in Minneapolis, Minnesota. "The banks will give us a good indication of underlying economic strength and what consumers and businesses are doing."

Chipmakers are among the biggest beneficiaries of the AI-led boom this year, fueled by expectations of massive spending by tech giants. But concerns about high valuations and profit-taking have recently led to volatility in the sector.

Preliminary data indicates that the S&P 500 closed up 28.72 points, or 0.38 percent, at 7,572.36, while the Nasdaq Composite rose 77.52 points, or 0.25 percent, to 26,273.21. The Dow Jones Industrial Average gained 148.28 points, or 0.28 percent, to 52,635.69.
