NVDA $91B Guidance Confirms AI Capex Cycle, ARM Gains 15% on Repricing

Nvidia's Q1 earnings report shattered consensus expectations and eliminated the last lingering doubt that hyperscalers were pulling back on artificial intelligence spending. The company posted $81.6B in revenue, a record, with data-center revenue accounting for $75.2B and GAAP net income reaching $58.3B. The forward guidanceCompany-issued forecasts of future financial performance. of $91B for next quarter was the headline that mattered most: three weeks prior, every major hyperscaler (Microsoft, Google, Meta, Amazon) had guided up on capex, but bears argued these increases would bypass Nvidia entirely or redirect toward alternative chips. That thesis is now dead.

The earnings call reinforced that the AI buildout remains in early innings. Management made clear that the $91B guidanceCompany-issued forecasts of future financial performance. excludes any contribution from China data-center compute, a nod to both regulatory headwinds and the company's strategic pivot to other markets. Investors obsessed over the forward P/E (25x), which has compressed from recent highs despite the guidance beat, suggesting the market has already priced in a long runway of elevated demand. What changed this week is the removal of execution risk: Nvidia no longer has to defend its capex thesis; the numbers speak.

The semiconductor rally widened beyond Nvidia to AMD (+7.3%), which benefited from renewed conviction that the AI-driven margin expansion story extends across the entire chip complex. ARM Holdings surged 15% to $256.59 as investors repriced the value of royalty flows from Nvidia's announced standalone Vera CPU revenue of ~$20B. Broadcom, AVGO, and other AI-enabling chip suppliers all benefited from the knock-on lift. Yet the concentration risk remains acute: NVDA and the top four megacaps now drive over 40% of S&P 500 returns YTD, a level last seen before prior corrections.

The debate among portfolio managers now centers on breadth: will semiconductor strength and tech confidence spark broader rotation into cyclical and defensive names, or will the concentration deepen further as AI remains the only growth story credible enough to justify current valuations. Equal-weighted S&P 500 remains flat since the Iran war began, suggesting that gains are still narrowly distributed. If Nvidia can sustain this momentumThe empirical fact that winners keep winning over the medium term. through earnings season and capex revisions don't disappoint, the narrative could shift to 'rotation out of NVDA into chip suppliers and AI enablers.' Until then, the stock remains the sole fulcrum of equity risk appetite.
