The Trade Desk, a leading digital advertising platform, has been added to the S&P 500 index, a significant milestone reflecting the company's growth and success in the digital advertising space. The inclusion in the S&P 500 index is expected to drive increased visibility, liquidity, and potentially lower the cost of capital for the company [1].

The Trade Desk specializes in online advertising space purchase and optimization, serving over 1,100 customers, primarily advertising agencies and independent advertisers. The company has experienced a notable market cap hit this year, with shares down 36% in 2025, following a 63% jump in 2024 and a 61% increase in 2023. However, the recent addition to the S&P 500 is likely to boost investor confidence and drive stock performance [2].

The S&P 500 index typically attracts significant buying pressure when new companies are added, as index funds need to rebalance their portfolios. The Trade Desk's inclusion comes amidst growing importance of digital advertising technology companies in the broader market landscape [3].

The company, founded in 2009 by CEO Jeff Green and David Pickles, went public on the Nasdaq in 2016. With over 3,522 employees as of Dec. 31, The Trade Desk competes against companies including Amazon and Google. The company's addition to the S&P 500 replaces software maker Ansys, which is being acquired by Synopsys [1].
