As of August 2025, eleven companies have crossed the $1 trillion market cap mark. Aside from oil giant Saudi Aramco, Taiwan’s TSMC, and electric vehicle pioneer Tesla, all are U.S.-based tech firms, reflecting how digital innovation continues to dominate the world’s most valuable companies.
In a historic leap on October 29, 2025, American chipmaker Nvidia became the first company to surpass a $5 trillion market capitalisation, fueled by booming demand for AI infrastructure and a massive partnership with OpenAI (in which Nvidia may invest up to $100 billion) to expand high-power AI data-centres. Nvidia now clearly dominates the AI-accelerator market and stands to benefit significantly from new AI data-centre spending. Microsoft and Apple have also crossed the $4 trillion threshold, Apple briefly doing so for the first time on October 28, driven respectively by surging cloud and AI-service demand in Microsoft’s Azure division, and by Apple’s record iPhone 17 sales, alongside growing investor enthusiasm for its on-device ‘Apple Intelligence’ ecosystem. This reflects a broader trend: tech giants at the forefront of AI are not just redefining corporate value, they are reshaping the global economic hierarchy.
Inspired by these trends, our team at BestBrokers set out to forecast which of the current trillion-dollar giants is poised to be the next one to reach the $5 trillion milestone, which is likely to follow into the $4 trillion tier, and which companies with market caps still under $1 trillion are most likely to cross the trillion-dollar threshold next. We based our analysis on their market capitalisations as of October 29, 2025, extrapolating from their historical average growth rates since 2022.
Our projections indicate that Microsoft is on track to become the second company to top $5 trillion, potentially in less than 10 months. Google (Alphabet) is not far behind, with a $5 trillion market capitalisation possible in October 2026. Apple is projected to follow in early 2027, while Broadcom, propelled by an extraordinary 112.04% average annual growth rate, is expected to reach the milestone just a month later.
Microsoft and Google have the potential to reach $5 trillion market capitalisation in less than a year
The race to the next major market cap milestones is intensifying after Nvidia crossed the $5 trillion mark, with Microsoft leading the charge as its cloud and AI businesses scale rapidly. Valued at $3.94 trillion as of October 29, 2025, the tech giant’s market capitalisation surged 31.89%, compared to 2024. If the current pace continues, the company might reach a market cap of $5 trillion by August 18, 2026.
Google (Alphabet) is not far behind and is expected to follow in October, 2026, only two months after Microsoft. Recently, Google topped $100 billion quarterly revenue for first time ($102.35), which surpassed the estimated $99.89 billion, driven by 34% growth in Cloud, strong AI adoption, and a $155 billion backlog of enterprise contracts.
Hot on Google’s heels are Apple and Broadcom, with market capitalisations of $4.03 trillion and $1.78 trillion, respectively, and projected timelines to reach $5 trillion on January 14, 2027, and February 20, 2027. While Apple’s three-year average growth rate stands at a modest 18.47%, it remains the only company besides Nvidia to sit above the $4 trillion mark. Broadcom, on the other hand, has delivered an extraordinary 112.04% average annual growth rate despite its comparatively smaller valuation. This paints an intriguing competition: while Apple is advancing through steady, sustained expansion, Broadcom is sprinting ahead on explosive momentum.
Beyond the front-runners, a second tier of companies is emerging as potential future giants. Meta Platforms, with a market cap of $1.68 trillion and a staggering three-year growth rate of 97.06%, could reach $5 trillion by May 19, 2027, while Taiwan’s TSMC and Amazon are projected for October 2027 and May 2028, respectively. Tesla and Oracle are on longer trajectories toward $5 trillion, with expected milestones stretching into 2029-2030.
As 2025 unfolds, the race toward $5 trillion market caps is about more than just numbers, it reflects where innovation, strategy, and investor sentiment are converging to reshape the global economic landscape. Microsoft, Google, and Broadcom are rewriting expectations, while the industry watches keenly to see who will claim the next milestone.
Who’s Next to Join the $4 Trillion Elite?
While Microsoft reached $4 trillion earlier in 2025, Apple recorded the same success in late October. Less than a year ago, Apple was the world’s most valuable company, just some $150 billion short of а $4 trillion capitalisation. Following the announcement of U.S. President Donald J. Trump’s tariffs, its stock lost roughly 20% of its value within just three days in April. This wiped out nearly $640 billion of its market capitalisation amid a broader impact on the market resulting from the tariff announcements and the ensuing trade war. Since then, Apple stock has surged nearly 50%, bringing the market cap to over $3.8 trillion and eventually securing its position above the $4 trillion mark.
Alphabet (Google) also has the potential to join the $4 trillion elite soon. Now valued at $3.45 trillion with a 42.56% three-year growth rate, it’s projected to surpass $4 trillion by May 2026. Broadcom, meanwhile, shows the strongest growth rate among the top firms, but despite its impressive momentum, it’s unlikely to overtake Alphabet in the race soon, mainly due to Google’s almost twice larger market cap and more diversified global presence.
Meta also shows an impressive average annual growth rate of 97.06%, positioning it as one of the fastest-growing companies in the trillion-dollar group. Despite its current market cap of $1.68 trillion, which is notably lower than Amazon’s $2.40 trillion, the social media giant appears poised to overtake Amazon within the next few years. Projections show that while Meta may reach the $4 trillion mark in January 2027, Amazon is likely to be the final entrant of the year, reaching the mark on August 8.
JPMorgan, Oracle, Walmart, or Tencent – who will reach $1 trillion market cap first?
According to our estimates, five of the world’s largest public companies are on the cusp of joining the trillion-dollar club within the next year. Our projections, however, follow very bullish scenarios where these companies’ exceptionally fast growth continues at the same pace.
Financial powerhouse JPMorgan Chase, valued at around $842 billion, and Oracle, at approximately $766 billion, are racing neck and neck, both projected to join the trillion-dollar club just five days apart, on May 10 and May 15, 2026, respectively. JPMorgan’s expansion into AI-driven financial services and digital banking mirrors Oracle’s aggressive pivot toward cloud infrastructure and enterprise automation, illustrating how even traditionally conservative sectors are embracing innovation to sustain competitiveness in an AI-dominated era.
Walmart is in third position to join the $1 trillion club, with a market cap of $818.9 billion and an average annual growth rate of 29.84%. Its growth is fueled by e-commerce expansion, AI-driven inventory management, and logistics innovations. At this pace, Walmart is expected to reach $1 trillion by July 2026, reflecting its transformation into a tech-driven retail powerhouse.
Eli Lilly and Visa are among the fastest-growing non-tech companies nearing the trillion-dollar threshold. Eli Lilly, with a market cap of $738.59 billion and a 31.9% three-year growth rate, is projected to reach $1 trillion by November 2026, driven by strong pharmaceutical pipelines and ongoing breakthroughs in treatments. Visa, with a market cap of $669.65 billion and a more modest growth rate of 15.46%, is expected to surpass companies like Samsung (which recently entered the world’s top 20 by market capitalisation, replacing Netflix) and its financial rival Mastercard, potentially joining the club by July 2028.
Exxon Mobil, the energy giant valued at $494 billion, has a stagnant three-year growth rate of just 3.57%, suggesting it is unlikely to reach the $1 trillion mark before 2045. This illustrates how legacy industries are expanding far more slowly, while innovation-driven sectors, particularly in technology, pharmaceuticals, and finance, are redefining the speed of corporate value creation.
Methodology
Our team at BestBrokers looked at the 20 most valuable global companies as of October 29th, 2025, sourced from CompaniesMarketCap.com. We calculated how much each company’s market capitalisation has increased on а year-over-year basis between October 2022 and October 2025, and took the average of these percentages. We then applied this average growth rate to every firm’s market capitalisation as of the time of preparing this report. This allowed us to project the approximate time it will take for each company to reach a market value of $1 trillion, $4 trillion, and $5 trillion, starting from the date at the time of writing.
