3 High-Conviction Growth Stocks Set to Outperform in 2026

The 2026 investment landscape is poised for a seismic shift as artificial intelligence (AI), e-commerce, and space technology converge to redefine global markets. Strategic catalysts-ranging from infrastructure investments to geopolitical demand-are accelerating market realignment, creating opportunities for companies with first-mover advantages. Below, we analyze three high-conviction growth stocks across these sectors, each positioned to capitalize on transformative trends.

1. NVIDIA (NVDA): The AI Infrastructure Engine

NVIDIA remains the linchpin of the AI revolution, with its data-center revenue surging 93% year-over-year in Q1 2025. The company's GPUs power everything from generative AI models to autonomous systems, making it indispensable for enterprises seeking to scale AI capabilities. A critical catalyst is NVIDIA's partnership with U.S. infrastructure firms to build up to $500 billion in AI infrastructure over four years. This aligns with PwC's prediction of disciplined AI adoption, where targeted deployments drive value.

Moreover, NVIDIA's dominance in AI chips ensures it benefits from the "barbell portfolio" strategy recommended by JPMorgan, which pairs high-growth AI stocks with cyclical plays. As AI adoption accelerates in e-commerce (e.g., Amazon's AI assistant "Rufus") and space tech (e.g., satellite data processing), NVIDIA's ecosystem of hardware and software will remain a critical enabler.

2. AST SpaceMobile (ASTS): Redefining Satellite Connectivity

AST SpaceMobile is disrupting the space tech sector with its direct-to-device (D2D) 5G and LTE satellite connectivity. A $175 million prepayment from Saudi Arabia validates its commercial viability, as the company bypasses traditional ground infrastructure to deliver broadband directly to mobile devices. This innovation addresses a $1.2 trillion global market gap for reliable connectivity in remote and underserved regions.

The strategic acquisition of SciTec by Firefly Aerospace and Voyager Technologies' Starlab project highlight the sector's competitive intensity. However, AST SpaceMobile's first-mover advantage in D2D technology, coupled with growing defense and national security demand, positions it to outperform peers. As JPMorgan notes, space tech stocks are ideal for portfolios seeking exposure to "moonshot" innovations with clear revenue catalysts.

3. MercadoLibre (MELI): E-Commerce's Latin American Powerhouse

MercadoLibre, the dominant e-commerce platform in Latin America, is leveraging AI and financial technology to solidify its market leadership. Its gross merchandise volume (GMV) grew 35% year-over-year in Q3 2025, driven by expanding digital payments and logistics networks. The company's financial services arm, which includes credit and insurance products, now accounts for 30% of revenue, creating a sticky ecosystem for users.

AI integration is a key differentiator: MercadoLibre's use of machine learning for personalized recommendations and fraud detection mirrors Amazon's strategies but is tailored to Latin America's fragmented market. As e-commerce adoption accelerates in the region-projected to grow at 15% annually through 2026-MercadoLibre's dual focus on AI-driven retail and financial inclusion positions it as a regional bellwether.

Conclusion: A Barbell Strategy for 2026

The three stocks above represent a balanced approach to 2026's investment opportunities. NVIDIA embodies the AI infrastructure boom, AST SpaceMobile captures the space tech renaissance, and MercadoLibre taps into e-commerce's untapped potential in emerging markets. Together, they align with JPMorgan's barbell strategy, combining high-growth AI plays with cyclical and international opportunities.

As market realignment accelerates, investors should prioritize companies with clear strategic catalysts-whether through technological innovation, geopolitical demand, or regional expansion. These three stocks offer a compelling roadmap for navigating the next phase of the AI-driven economy.
