Aug 4 (Reuters) – Wall Street’s benchmark S&P 500 hit an intraday record high for the ​first time since early June ‌on Tuesday, boosted by upbeat AI-driven forecasts from Caterpillar and Palantir and hopes for an imminent deal to end tensions ‌in ​the Middle East.

Recent ⁠gains on Wall Street ⁠have been driven by strong earnings from AI heavyweights such as Amazon and Microsoft that reassured ​investors that their billion-dollar investments were yielding returns.

The blue-chip Dow ⁠was also trading ⁠at a fresh intraday record ​high.

The S&P 500 had retreated from ​all-time highs as tensions between Iran ‌and the U.S. resurfaced in early June and concerns about elevated valuations following a strong second-quarter ⁠rally weighed on AI-related stocks through July.

The Dow Jones Industrial Average rose 462.8 ⁠points, or ‌0.87%, at the open ⁠to 53,641.21. The S&P ​500 ‌rose 30.1 points, or 0.40%, ​at ⁠the open to 7,630.62, while the Nasdaq Composite rose 174.1 points, or 0.67%, to 26,088.042 at the opening bell.
