Nvidia Adds 442 Billion Dollars in a Day, Second Biggest Gain in Stock Market History
Nvidia added 442 billion dollars to its market value on Thursday, according to Bloomberg, which called it the second largest one-day gain by any stock in history. Shares rose 8.7 percent after the chipmaker’s second quarter results and forecast reassured investors that demand tied to artificial intelligence remains strong. The move trails only Microsoft’s 450 billion dollar surge on 30 July 2026, the largest single-day gain by any stock on record.
A near half trillion dollar day
Nvidia shares rose 8.7 percent Thursday, their biggest one-day advance since April 2025, according to Bloomberg. Separately, CNBC put the shares up 8.74 percent to 227.98 dollars and Thursday’s market value gain at about 440 billion dollars. Nvidia’s valuation stood at around 5.5 trillion dollars after the move, making it the world’s largest company by market value.
Nvidia’s 442 billion dollar gain on Thursday came within 8 billion dollars of Microsoft’s 450 billion dollar record from 30 July 2026, a gap of less than 2 percent, both figures on our calculation. Microsoft’s 450 billion dollar gain had itself eclipsed an earlier Nvidia one-day gain of about 440 billion dollars, which followed markets’ reaction to a tariff pause announced in 2025 and was, at the time, the largest single-day gain on record.
Largest one-day dollar gains by a single stock
| Company | Date | Value added |
|---|---|---|
| Microsoft | 30 July 2026 | $450 billion |
| Nvidia | 27 August 2026 | $442 billion |
| Nvidia | 2025 | $440 billion |
Ranked by value added. The 2025 Nvidia gain followed markets’ reaction to a tariff pause announced that year and was, at the time, the largest on record.
What drove the move
Nvidia reported second quarter revenue of 96.2 billion dollars, up 106 percent from a year earlier, with Data Center revenue of 89.0 billion dollars, up 117 percent. Data Center accounted for about 92.5 percent of total revenue in the quarter, on our calculation. The company guided to third quarter revenue of 108.0 billion dollars, plus or minus 2 percent. Nvidia Chief Financial Officer Colette Kress said the company expects revenue growth of about 70 percent for fiscal 2028, and Chief Executive Officer Jensen Huang said demand is running well ahead of that figure, though supply constraints limit how much the company can ship, according to CNBC. Huang added that artificial intelligence has reached an inflection point, pointing to a broader base of AI labs, startups and enterprise customers beyond the small number of large customers that drove the buildout a year earlier.
Chip stocks broadly rallied on the results. Broadcom and Intel both rose, and shares of neocloud provider Nebius also gained, while CoreWeave fell 1.37 percent.
Why it matters
A near half trillion dollar addition to a single company’s value in one session is a measure of how concentrated the current market’s largest gains have become in a small number of companies tied to artificial intelligence infrastructure. That Nvidia’s Thursday gain and Microsoft’s late July record both rank among the largest single day dollar gains for any stock, and that both were driven by cloud and AI-related guidance beating expectations, points to how sensitive the largest companies in the market now are to a narrow set of AI demand signals. Nvidia’s own supply constraints, repeated across its earnings commentary, are, on our reading, also a factor behind the size of these moves.
Outlook
Markets will watch whether Nvidia’s guidance for about 70 percent revenue growth in fiscal 2028 holds up against actual demand, which Huang has said is running ahead of that pace, and whether the supply constraints Huang described ease enough to let the company meet it. The comparison with Microsoft’s record will also remain a reference point for how markets are pricing the largest AI-linked companies going forward.
