Q2 2026 Earnings Review: Performance, Market Revisions, Sentiment

The S&P 500 continued its march to fresh all-time highs through Q2 2026, extending a rally that has defined much of the year, before a bout of late-summer volatility took hold as renewed US-Iran hostilities reignited the energy-price and inflation concerns that first surfaced back in February.

The index has pulled back modestly from its highs heading into September, with oil prices and Treasury yields climbing on the fresh round of strikes in the Persian Gulf, and rate-hike speculation creeping back into the conversation as inflation data runs hotter. Against that backdrop, Q2 earnings delivered another standout quarter, with 78% of companies beating EPS estimates and a year-over -year increase in earnings of a whopping 53%.

As has been the pattern for some time now, the AI theme remained the dominant driver within IT, with the Magnificent Seven's cloud and AI revenues broadly outpacing expectations once again and the sector leading year-over-year earnings growth. With the market now digesting both a historic earnings season and a reignited geopolitical shock, the key question heading into Q3 is whether corporate fundamentals can continue to outrun the macro overhang.
