Nvidia (NVDA 0.48%) announced its next-generation chip platform, Vera Rubin, in January this year, promising major cost reductions for training artificial intelligence (AI) models and running inference applications.
Nvidia claims that the Vera Rubin platform can reduce the cost of AI inference by 90% compared to the previous-generation Blackwell platform. Additionally, it can lower the number of graphics processing units (GPUs) needed to train AI models by 75%. These major gains explain why customers are probably lining up to purchase Nvidia's Vera Rubin chips.
CEO Jensen Huang recently pointed out that Nvidia has a whopping $1 trillion worth of combined orders for its Blackwell and Vera Rubin chips through 2027. That's a major increase when compared to Nvidia's previous guidance of $500 billion in combined orders for both these chip platforms through 2026. So, Nvidia stock could get a major boost when the Rubin chips hit the market in the second half of 2026.
But at the same time, two other companies could win big from the Rubin platform. Let's take a closer look at them and see why they are worth buying for investors looking to construct a million-dollar portfolio.

1. Micron Technology
Nvidia's Rubin chips are going to pack more memory capacity and higher bandwidth. The chip giant notes that the dynamic random-access memory (DRAM) capacity of the Rubin NVL72 rack-scale server will increase by 2.5 times over the Blackwell NVL72, and it will pack 1.5 times more high-bandwidth memory (HBM). What's more, the bandwidth of the HBM on Rubin chips will increase by 2.8 times over Blackwell, suggesting that they will be able to move more data at faster speeds in AI servers.
This is great news for Micron Technology (MU +4.80%) investors. The memory specialist has already commenced the high-volume production of HBM for Rubin chip systems, including both GPUs and central processing units. What's more, Micron is also producing enterprise solid-state drives (SSDs) for the Rubin platform.

Key Data Points
This explains why Micron's stunning growth is here to stay. The company expects $33.5 billion in revenue in the current quarter, a jump of 260% from the year-ago period. Even better, its earnings are set to jump to $19.15 per share in the ongoing quarter from $1.91 per share in the same period last year. HBM demand is playing a key role in this phenomenal earnings growth, driving an improvement in Micron's product mix due to the higher pricing that it commands.
Importantly, Micron's earnings are expected to grow at exponential rates from the previous fiscal year's reading of $8.29 per share.

Micron stock trades at just 20 times earnings right now, presenting investors with a great deal they should consider grabbing with both hands, as it can make them significantly richer in the long run. For instance, this AI stock could jump to $2,260 by the middle of next year if it trades at 23 times earnings at that time (in line with the tech-laden Nasdaq-100 index's forward earnings multiple), based on the $98.26-per-share earnings estimate shown in the chart above.
Micron can therefore jump sixfold from current levels, which is why investors looking to buy a potential growth stock for their million-dollar portfolio should consider buying it.
2. Taiwan Semiconductor Manufacturing
Nvidia relies on its foundry partner, Taiwan Semiconductor Manufacturing (TSM +0.42%), to produce the chips it designs. So, the massive sales forecast for the Blackwell and Rubin chip platforms through next year should ensure solid growth for TSMC, especially considering that it is on track to significantly expand its manufacturing capacity.
NYSE: TSM
Key Data Points
TSMC has guided for $52 billion to $56 billion in capital expenditures for 2026, up by almost a third over last year's $40.9 billion at the midpoint. The Taiwan-based company notes it will spend 70% to 80% of its budget on advanced process nodes. Given that the Rubin chips are reportedly going to be produced using TSMC's advanced 3-nanometer (nm) process node, it is easy to see why TSMC is going to aggressively bring additional capacity online.
Nvidia is TSMC's largest customer, accounting for 19% of its revenue, according to reports. TSMC reportedly received $23.2 billion in revenue from Nvidia in 2025, more than double the 2024 levels. As TSMC ramps up its production capacity and helps Nvidia fulfill the huge demand for its latest-generation chips, there is a good chance it will outperform Wall Street's growth expectations.
Consensus estimates project a 36% increase in TSMC's earnings in 2026 to $14.54 per share, followed by a relatively slower 23% increase in 2027 to $17.96 per share. However, the $1 trillion in orders Nvidia estimates through the end of next year should be enough for TSMC to clock faster growth.
Assuming TSMC's earnings jump to even $20 per share by the end of 2027 and it trades at 23 times earnings at that time, its stock price could reach $460.
That points to a potential 41% surge in TSMC stock, making the foundry giant an ideal investment for those looking to build a million-dollar portfolio.
