The S&P 500 surged 1.5% to 7,604 points on August 3, 2026, as Big Tech earnings gains and easing oil prices lifted investor sentiment and reinforced confidence in the market’s earnings-driven rally. The advance reflected a broader shift in how investors are pricing risk: with geopolitical tensions easing and corporate profits accelerating, equities found fresh momentum despite weeks of volatility that tested market confidence.
Big Tech delivered the primary catalyst. Amazon stock surged 15% on July 31 after the company reported stronger-than-expected second-quarter results, with AWS revenue climbing 37% year-over-year to $42.2 billion—significantly outpacing Wall Street’s forecast of 31% growth. CEO Andy Jassy told investors that AWS’s artificial intelligence business alone now runs at a rate exceeding $25 billion annually, up triple-digit percentage year-over-year, and the company raised its full-year 2026 capital expenditure guidance to $220 billion largely because of surging demand for AI infrastructure.
The broader earnings picture has been equally robust. Q2 2026 S&P 500 earnings per share grew an estimated 23.6% year-over-year, marking the sixth consecutive quarter of double-digit earnings growth and the second straight quarter exceeding 20% growth, according to NYSE data. Wall Street analysts have revised full-year 2026 S&P 500 earnings growth projections upward to 25%, compared with less than 16% at the start of the year, as companies across sectors have beaten expectations and raised guidance.
Oil prices also retreated sharply, with Brent crude dropping to around $83.40 a barrel and U.S. crude declining 6% to $79.60. The decline followed President Donald Trump’s announcement that he was calling off a planned military strike on Iran in favor of pursuing a deal framework. Trump said late Saturday that the U.S. would cancel the attack “subject to being able to rapidly make a deal,” citing progress toward an agreement that would include opening the Strait of Hormuz and ending Iran’s nuclear threat. Investors shed concerns about supply disruptions from Middle East escalation, repricing risk downward across both equities and commodities.
The pattern of market reaction to geopolitical news has become familiar in 2026. When Trump claimed in July that the Iran ceasefire was “over,” oil prices had jumped 6% and stocks fell. The reversal on August 3 underscores how quickly sentiment can shift when diplomatic progress appears to reduce the risk of supply-chain disruption. For investors, the key question now is whether the deal framework can hold through negotiations and prevent the conflict from reigniting.
The August 3 advance extended a rally that has defined 2026 so far. Year-to-date, the S&P 500 has climbed 9.4%, driven by strong earnings growth despite economic headwinds and persistent inflation concerns. The market’s resilience reflects a shift in investor focus: with earnings accelerating and the Federal Reserve holding rates steady, the primary driver of stock prices is no longer interest-rate expectations but corporate profit growth and the monetization of artificial intelligence investments. That shift has made Big Tech—and companies with clear paths to AI revenue—the market’s leadership engine.
