The USย programmatic advertisingย market posted a 33.9% year-over-year overall CPM gain in April 2026, according to DataBeat's May 2026 Programmatic Trends Report published on May 22, 2026. Month-over-month, overall CPMs climbed 25.9%, driven by a 2.6% rise inย display CPMsย and an 8.3% rebound inย video CPMs. The figures, drawn from anonymized data across the DataBeat network, cover more than $55 million in tracked monthly revenue, more than 35 billion monthly impressions, and signals from over 200 tracked bidders.

OpenX follows at 17% share of voice with a CPM of $1.09, though it recorded a 26.4% month-over-month decline. Amazon sits at 8% share with a $1.56 CPM, up 41.8% year-over-year. At the other end, VRTCAL and The Trade Desk each hold 6% share but recorded month-over-month CPM declines of 66.3% and 57.1%…
