Top 15 public SaaS companies on United States stock exchanges 2024, by market cap

The software-as-a-service (SaaS) industry continues to dominate the tech landscape, with Salesforce leading the pack among public SaaS companies on U.S. stock exchanges. As of November 2024, Salesforce boasts a market capitalization of over 310 billion U.S. dollars, highlighting the immense value investors place on subscription-based software models. This trend reflects the growing preference of businesses worldwide for flexible, scalable solutions over traditional upfront software investments.

Global growth and regional disparities

The SaaS market is poised for significant expansion across all regions, with Latin America emerging as the fastest-growing market. Projections indicate that Latin America's cloud and SaaS revenue will surge from six billion U.S. dollars in 2021 to 20 billion U.S. dollars by 2026, representing a compound annual growth rate of 28 percent. This rapid growth underscores the increasing global adoption of SaaS solutions, particularly in emerging markets.

Adoption trends and security concerns

SaaS adoption varies by company size, with smaller firms leading the charge. In 2023, companies with 1–500 employees reported a nearly 70 percent adoption rate, compared to just over 50 percent for large enterprises with more than 10,000 staff. However, as SaaS usage grows, so do security concerns. Identity and access governance topped the list of security worries with 43 percent of respondents in 2023, followed closely by third-party application access and permissions at 40 percent. These concerns highlight the need for robust security measures as businesses increasingly rely on SaaS solutions.
