TLDR
Nvidia shares reached an all-time intraday high of US$239.86 on 5 October 2026, lifting the chipmaker's market capitalisation to roughly US$5.80 trillion. Revenue guidance of US$108 billion for the third quarter of fiscal 2027 is driving confidence, though analysts warn valuations may already price in peak AI demand.
A number that took decades to reach
Nvidia shares touched US$239.86 intraday on 5 October 2026, an all-time high for the stock.[1] With 24.2 billion shares of common stock outstanding as of May 2026, that intraday print placed market capitalisation at roughly US$5.80 trillion.[2] A US$6 trillion valuation, a threshold no publicly listed company has previously crossed, sits less than 4 per cent above Monday's peak.
The revenue guidance doing the heavy lifting
Nvidia's outlook for the third quarter of fiscal 2027 calls for revenue of US$108.0 billion, plus or minus 2 per cent, and the market is treating that figure as the floor rather than a ceiling.[4] The second quarter of fiscal 2027 delivered record total revenue of US$96.2 billion, up 106 per cent on the prior year, which gives the guidance line some empirical grounding.[3]
Data-centre hardware is carrying nearly all of that revenue. Second-quarter data centre revenue reached US$89.0 billion, up 117 per cent year-on-year, accounting for about 92 per cent of everything Nvidia earned that quarter.[3] Chief executive Jensen Huang put the scale of the cycle plainly: "The buildout of AI factories, the largest infrastructure expansion in human history, is accelerating at extraordinary speed," Huang said.[3]
On the second-quarter earnings call in August, Huang pointed to a broadening customer base sustaining that pace. "The surge in AI demand is driving a global infrastructure buildout, supported by an expanding and diverse set of growth opportunities, spanning hyperscalers, AI labs, AI natives, enterprises, and sovereign customers," Huang told investors.[5]
Australian super funds and ASX-listed tech
Superannuation funds with global technology mandates have lifted their offshore allocations as domestic bond yields and real estate returns have compressed, and Nvidia sits as the largest holding in several global technology strategies accessible through the ASX.[1] A single-day swing of Monday's magnitude translates quickly into fund-level performance numbers that members read in their quarterly statements.
Where the scepticism sits
Some analysts argue that valuations at current levels already embed assumptions of peak AI demand being sustained indefinitely, leaving little margin for the operational frictions now visible in the supply chain. Memory shortages and component pricing pressures are flagged as a potential cap on margins, while supply bottlenecks could delay delivery of next-generation AI-optimised chips into calendar 2027.[1]
The forward revenue multiple implied by a US$5.80 trillion market capitalisation against US$108 billion in quarterly guidance, annualised approaching US$432 billion, leaves no room for a guidance miss. Nvidia's next scheduled financial results will provide the first hard test of whether the third-quarter forecast actually lands above the US$96.2 billion second-quarter print it is meant to surpass.
