The Trade Desk just got kicked out of the S&P 500 on the same day it fired 575 people.

575 jobs cut. 15% of the workforce. Largest layoff in company history.

But the number that should terrify you is this: The Trade Desk was dropped from the S&P 500 on September 4th — the exact same day those 575 employees officially left.

Not a coincidence. A consequence.

This was the crown jewel of independent adtech. A $2.9B revenue company with $1.5B cash and zero debt. And it just posted its slowest revenue growth since COVID — 3% year-over-year. Analysts are now projecting 15% sales declines in the second half of 2026.

CEO Jeff Green is calling this a "restructuring into smaller pods." The financial reality: $39M to $51M in restructuring charges. A stock down 70% over the past year. A CFO, CRO, CSO, and CMO all gone. Four board members departed. An insider trading charge against a former finance director.

And Amazon is eating their lunch. The same DSP competition that was a background threat two years ago is now the primary growth engine eating The Trade Desk's market share.

If your adtech stack depends on a single demand-side platform, you just watched your counterparty risk multiply overnight. Audit your vendor dependencies today.
