America’s 10 most valuable tech companies list has a new entrant that has ‘beaten’ IBM, Salesforce and Cisco

Palantir, a data analytics software company, climbed into the top 10 US technology firms by market capitalization after an 8% stock surge on Thursday (May 8), reaching a valuation of $281 billion. This leap pushed it past Salesforce, valued at $268 billion, which previously held the tenth spot. Earlier this year, Palantir also overtook tech stalwarts Cisco and IBM. Palantir’s stock has soared, more than quintupling in value over the past year and gaining 58% in 2025, making it the S&P 500’s top performer for the second consecutive year. While the Nasdaq has declined 7% this year amid tariff concerns and economic slowdown fears, Palantir has defied the trend.
