eToro Data Shows Retail Investors Broaden AI In Q2 2026

eToro has released its second-quarter (Q2) 2026 retail investor data, revealing the companies that recorded the largest quarter-on-quarter increase in holders, alongside the platform’s 10 most-held stocks.

Flash memory and storage company SanDisk recorded the biggest increase in holders globally during the quarter. ServiceNow ranked second, followed by Marvell Technology, Constellation Energy, and Planet Labs.

The data indicates that retail investors expanded their exposure beyond large technology companies and into businesses supporting artificial intelligence infrastructure. SanDisk saw a 151% increase in holders, while Western Digital recorded a 49% rise, reflecting growing interest in memory and storage companies as demand from AI data centres continues to grow. Marvell Technology also posted an 84% increase, highlighting continued investor interest in networking and semiconductor hardware.

Software companies remained popular as ServiceNow recorded a 102% rise in holders for the second consecutive quarter on the top-risers list, while Intuit gained 68%. eToro said the figures suggest investors remain confident in enterprise software companies integrating AI capabilities.

Energy infrastructure also attracted attention. Constellation Energy, the largest operator of nuclear power plants in the United States, recorded an 83% increase in holders, while Bloom Energy narrowly missed the top 10 with a 38% rise.

Lale Akoner, Global Market Strategist at eToro, said the data suggests retail investors are entering a more mature phase of AI investing by looking beyond the largest technology firms and identifying businesses with supply-chain advantages, including memory storage and power generation. She added that investors continue to hold major technology stocks while diversifying into other parts of the AI ecosystem.

The commercial space sector also gained momentum during the quarter. Planet Labs recorded a 75% increase in holders, while Intuitive Machines rose 60%. AST SpaceMobile also featured among the strongest performers, suggesting increasing retail interest in satellite communications and space-related businesses.

Meanwhile, the biggest declines in holders came from Sezzle, followed by Oscar Health, Equinor, ConocoPhillips, Occidental Petroleum and Petroleo Brasileiro. According to Akoner, the reduction in energy holdings reflects investors rotating away from trades driven by earlier oil supply concerns and toward emerging AI-related themes.

Despite these portfolio shifts, Nvidia, Tesla, Amazon, Microsoft and Apple remained eToro’s five most-held stocks, with little change in investor ownership during the quarter.
