In late June 2026, Monolithic Power Systems, Inc. was added to the Russell Top 200 Index and Russell Top 200 Growth Benchmark while being removed from the Russell Midcap and Russell Midcap Growth indices, shifting it into a larger-cap benchmark universe. This index migration coincides with heightened expectations for AI and data center demand, as management raised enterprise data growth guidance and expanded manufacturing capacity. The company’s April 30 guidance for Q2 2026 revenue of US$890 million to US$910 million and mid 50s gross margins anchors expectations around the same enterprise data and AI themes. Monolithic Power Systems' narrative projects $5.5 billion revenue and $1.6 billion earnings by 2029, implying 23.1% yearly revenue growth and an earnings increase of about $920 million from $679.7 million today. Some analysts were already cautious, assuming revenue of about US$5.3 billion and earnings near US$1.5 billion by 2029, highlighting how delayed ramps in AI data center and automotive products could still weigh on outcomes despite the recent index upgrade.
