Nvidia’s earnings report today could shake global markets – here’s what to watch
As Wall Street braces for Nvidia’s fourth-quarter fiscal 2026 earnings report after the bell today, the chip giant’s performance is poised to send shockwaves through global markets.
With a market capitalisation exceeding $4 trillion, Nvidia has become the world’s most valuable company, wielding outsized influence on everything from US indices to international tech sectors.
Investors are on edge, as the results could either reignite enthusiasm for the AI boom or amplify growing skepticism about the sustainability of massive spending on artificial intelligence infrastructure.
Nvidia’s tame 2026
Nvidia’s stock has underperformed broader markets this year, rising just 2% amid a Nasdaq decline of over 2.5%, while peers like Microsoft and Amazon have suffered double-digit drops.
This muted performance reflects broader concerns over Big Tech’s projected $630 billion in capital expenditures for AI has sparked doubts about whether returns justify the costs.
Analysts like those at Wedbush Securities note that hyperscale capex for 2026 has exceeded prior forecasts, with AI servers driving much of the growth.
Nvidia itself has fuelled uncertainty by scaling back a potential $100 billion investment in OpenAI, one of its key customers.
A behemoth in the stock market
The stakes are high because Nvidia’s weighting in major indices amplifies its impact. It accounts for nearly 8% of the S&P 500 and about 7% of the Morningstar US Market Index, making it a lynchpin for many mutual funds and ETFs.
Over the past year, Nvidia has contributed 15% to total market returns, underscoring the risks of such concentration. A strong report could create a ‘halo effect’ for the semiconductor sector, boosting stocks like AMD and TSMC, while a miss might drag down the broader tech ecosystem.
Analysts project revenue of $65 to $66 billion for the quarter, a 68% year-over-year jump, driven largely by the data centre segment at around $60 billion. Earnings per share are forecasted at about $1.52, with full-year 2027 estimates ranging from $6.28 to $9.68.
The company’s Blackwell GPUs are a focal point, with revenue expected to surge to $93.7 billion this year from $7.1 billion last year.
Prediction markets give Nvidia a 95% chance of beating estimates, supported by strong demand signals from clients like Microsoft and Amazon.
Darkening clouds
However, headwinds loom. Competitive pressures are mounting as hyperscalers develop their own AI chips to cut costs. Geopolitical risks, including potential U.S.-China trade tensions under a Trump administration, could disrupt exports – Nvidia has faced bans before.
Market watchers highlight the report’s potential to trigger volatility in the S&P 500, with implied moves suggesting a significant swing in Nvidia’s stock.
If Nvidia delivers another blowout, it could validate the AI supercycle and propel indices higher. But any signs of slowing growth might confirm fears of an AI bubble, leading to a broader sell-off.
