Wall Street’s first look at Big Tech’s $6 trillion combined market cap comes with >25% earnings growth expectations for Alphabet and Tesla and a recent 25% IBM
Investors will get their first look at how the four biggest U.S. tech firms—Alphabet, Tesla, IBM and ServiceNow—are performing on Wednesday after the bell, a batch that represents roughly $6 trillion in market value, or about 21% of U.S. GDP, making the earnings season a macro‑level health check for the economy【1】.
| At a glance | |
|---|---|
| Combined market cap | $6 trillion (≈21% of U.S. GDP) |
| Expected YoY earnings growth | >25% for Alphabet and Tesla |
| IBM prior reaction | Stock fell 25% on July 14 after weak Q2 preview |
| S&P 500 status | No new all‑time high since early June |
Analysts, according to LSEG data, are forecasting year‑over‑year earnings growth of more than 25% for both Alphabet and Tesla, while IBM and ServiceNow are expected to post modest profit expansion versus a year ago【1】. These projections come after IBM’s preliminary Q2 results missed consensus, triggering its steepest single‑day decline on record—down 25% on July 14【1】. The market’s sensitivity to these reports is heightened by the fact that the S&P 500 has stalled below its early‑June peak, and early trade on Wednesday already showed equities slipping as higher oil prices and rising U.S.–Iran tensions weighed on sentiment【1】.
Ben Emons, CIO of FedWatch Advisors, notes that the combined market cap of the four companies equals roughly one‑fifth of U.S. GDP, meaning that strong earnings from Alphabet or Tesla could validate the ongoing AI capital‑expenditure ripple through upstream industrial supply chains【1】. Conversely, IBM and ServiceNow results may signal whether downstream software and services revenue are stabilizing, potentially supporting the broader memory and software sectors that have been under pressure【1】. The earnings season therefore acts as a “micro event” with the potential to influence macro‑economic narratives, especially as investors gauge the sustainability of AI‑driven growth and its impact on the overall market.
The outcomes of these four earnings reports will either reinforce the current optimism around AI‑driven growth or expose vulnerabilities that could dampen the broader market’s trajectory, leaving investors to watch closely how the “health check” translates into macro‑level market moves.
