AI ambitions are getting bigger. SoftBank is now trying to raise up to US$100b from Gulf investors to buy and build businesses around artificial intelligence. That kind of money concentrates attention on companies already targeting strong expansion, backed by confident management teams and bullish analysts. This article walks through three high conviction, high growth stocks from the screener that aim to capture that momentum for long term focused investors.
The three stocks highlighted next are just a sample, and the full screen surfaced 48 more businesses with similarly strong growth stories and confident outlooks that are not covered here.
If you want to identify and analyze the highest conviction ideas in one place, head straight into the High Growth High Conviction screener .
Arista Networks (ANET)
Overview:Arista Networks builds data center and AI-focused cloud networking hardware and EOS software that connect large-scale internet, cloud, and enterprise environments worldwide.
Operations:Arista generates about US$10.54b from computer networking products and services, supported by sizeable demand across the United States, EMEA, Asia Pacific, and the rest of the Americas.
Market Cap:US$272.21b
Arista Networks fits the High Growth High Conviction theme because its Ethernet switches and software are directly wired into the buildout of AI and cloud data centers, giving the business a central role in how hyperscalers move enormous amounts of data efficiently.
"Accelerated adoption of AI and machine learning workloads continues to increase demand for high-bandwidth, low-latency networking infrastructure, and Arista Networks is now guiding AI fabrics revenue of at least US$3.5b to US$3.6b in 2026 with Etherlink already used by more than 100 customers."
What matters next is how one pressure on Arista Networks' AI buildout plans ultimately feeds through to earnings power and long term demand.
To see how that pressure could reshape Arista Networks' AI earnings profile, read the full narrative for Arista Networks to understand what accelerating or stalled demand might really signal.
ERock (EROC)
Overview:ERock provides modular, natural gas based distributed power systems and long term service support for data centers, utilities, and industrial customers.
Operations:ERock generates about US$162 million from electric equipment solutions across the United States, tied to distributed modular power projects.
Market Cap:US$3.53b
ERock matters for this High Growth High Conviction screen because its modular, dispatchable power units are directly aligned with rising on site demand from AI heavy data centers and grid constrained customers. This is an area where many investors are currently focusing on scalable growth stories.
"AI driven load growth and grid constraints are increasing demand for rapid, on site generation, and ERock's 1.7b contracted backlog and production capacity sold out through 2027 and into 2028 create visibility that can support future revenue and EBITDA as projects convert."
What happens to ERock's margins and cash generation will depend on how one unseen pressure in those long duration contracts ultimately plays out.
If that contract risk feels pivotal, read the full narrative for ERock to see whether ERock's backlog is quietly masking upside or compressing future returns.
Nu Holdings (NU)
Overview:Nu Holdings runs Nubank, a digital banking platform offering app based accounts, cards, payments, lending, and financial services across Latin America.
Operations:Nu Holdings generates about US$8.44b from banking activities, primarily across Brazil, Mexico, and other Latin American markets.
Market Cap:US$75.26b
Nu Holdings fits the High Growth High Conviction screen because Nubank's fast growing personal, credit card, and business account ecosystem directly supports management and analyst expectations for sustained expansion.
"The Central Bank of Brazil (Banco Central do Brasil) has watched Nu's rise with a mixture of admiration and caution. In late 2025, it issued new requirements that will compel Nubank to obtain a full banking license in Brazil by 2026."
What happens to Nu Holdings' profitability profile may hinge on how that single regulatory shift interacts with its low cost digital model at scale.
That licensing pivot is the real hinge for Nu Holdings, and the full narrative for Nu Holdings shows whether regulatory friction is actually accelerating Nubank's scale advantage.
