Nvidia reclaimed the $5 trillion market capitalization mark on Friday, gaining 5.2% in afternoon trading and adding roughly $260 billion in value in a single session as a powerful chip-sector rally pushed the Nasdaq Composite toward a fresh record. Shares traded around $209, just shy of the $212.19 all-time intraday high set on October 29, 2025, when the company first crossed the $5 trillion threshold.
A $1 Trillion Lead Over Alphabet
The advance restored Nvidia's status as the world's most valuable public company by a wide margin. With the chipmaker back above $5 trillion, Nvidia now sits roughly $1 trillion ahead of second-place Alphabet, which carries a market cap near $4.1 trillion. The gap underscores how concentrated the AI trade has become in a single name, even as the broader semiconductor complex extends one of its longest winning streaks on record.
The PHLX Semiconductor Index notched its 18th consecutive day of gains on Friday, a stretch that has carried the broader chip group to record territory alongside its largest member. Intel's blowout first-quarter report — which sent that stock up roughly 27% — provided additional fuel for the group, but Nvidia did the heavy lifting on the day in dollar terms.
The Oklo Catalyst
A second catalyst arrived from an unexpected corner of the market. On April 23, small modular reactor developer Oklo announced a three-way collaboration with Nvidia and Los Alamos National Laboratory targeting nuclear fuel validation and AI-driven reactor research. The arrangement pairs Nvidia's accelerated computing infrastructure with Oklo's reactor development pipeline and Los Alamos's modeling expertise.
Oklo shares responded with a 15.65% rally on Thursday and added another 5% on Friday, climbing to roughly $80. HSBC initiated coverage of the company with a Buy rating and a $96 price target, citing the strategic value of locking in dedicated baseload power for AI data centers.
The deal speaks to a constraint that has quietly become the central bottleneck for the AI build-out. Nvidia's customers are racing to stand up "AI factories" that require power profiles measured in gigawatts and uptime that intermittent renewables cannot deliver alone. Nuclear, and small modular reactors in particular, have moved from the margins of the energy debate into the heart of hyperscaler capacity planning over the past twelve months.
Macro Backdrop
The chip rally landed against a constructive macro tape. The Department of Justice announced it would drop its criminal probe into Federal Reserve Chair Jerome Powell, removing an overhang that had weighed on broader market sentiment and potentially clearing a path for the confirmation of President Trump's nominee Kevin Warsh. The S&P 500 added 0.7% on the session, while the Dow Jones Industrial Average slipped 0.3%, a divergence that reflected the rotation into mega-cap technology.
Investors now turn to the April 28-29 Federal Open Market Committee meeting, where the central bank is widely expected to hold the federal funds rate in its current 3.5%-3.75% range. The March CPI print showed headline inflation accelerating to 3.3% year over year — the hottest reading since April 2024 — a backdrop that complicates the Fed's stated preference for one rate cut later this year.
For Nvidia bulls, however, the macro debate has been a sideshow. The combination of relentless data center capex, an expanding power-supply ecosystem now spanning hyperscalers and nuclear startups, and a chip cycle that has shrugged off every macro headwind thrown at it has left the stock sitting on a market cap larger than the GDP of every country except the United States and China.
