Arm Holdings (NASDAQ: ARM) has surpassed x86 as the leading platform in AI servers, according to new data from research firm IDC, reinforcing its unique position in the semiconductor industry.
IDC’s first-quarter AI infrastructure report revealed that accelerated server value on Arm climbed to $53 billion, up from below $30 billion as recently as the third quarter of 2025.
The research firm also raised its full-year forecast for AI infrastructure spending to $497 billion, a figure that underscores the scale of capital flooding into the sector.
Arm’s business model sets it apart from every other player in the chip industry, because it licenses its architecture and collects a royalty on every chip shipped using it.
This means that competition among chipmakers is, in practical terms, a competition among Arm’s own customers, leaving the company to collect revenue from all sides.
Apple (NASDAQ: AAPL), Qualcomm (NASDAQ: QCOM), Samsung, and MediaTek all build their smartphone chips on Arm’s architecture, giving the company deep penetration across the consumer device market.
In fiscal 2026, which ended March 31, Arm posted record revenue of $4.92 billion, a 23% increase year-over-year, with royalty revenue alone reaching $2.6 billion.
Analysts expect earnings per share growth of 23% in fiscal 2027, followed by 42% in 2028, 32% in 2029, and 50% in 2030, reflecting the delayed but durable nature of royalty income.
The company carries a forward GAAP price-to-earnings ratio of 239.88x and a price-to-sales ratio of 51.84x, signaling that markets have already priced in years of anticipated royalty growth.
Arm’s balance sheet provides a degree of financial stability, with roughly $310 billion in market capitalization, virtually no debt, and $3.6 billion in cash on hand.
One area of investor uncertainty surrounds reports that Arm may begin selling its own chips, a move that would put it in direct competition with its own licensees and introduce lower-margin silicon business into the mix.
Building chips carries far thinner margins than licensing architecture, and at current valuation multiples, the market is clearly pricing Arm as a high-margin licensing company rather than a hardware manufacturer.
Over the past year, ARM stock has returned approximately 75%, a strong result in absolute terms, though it trailed the iShares Semiconductor ETF (SOXX), which gained around 126% in the same period.
That performance gap suggests the AI investment wave lifted the broader chip sector more evenly than expected, rather than concentrating gains in a handful of dominant names.
