Ad Tech Briefing: The Trade Desk’s CFO search indicates a tough road ahead for independents

Earlier this week, The Trade Desk announced the exit of Alex Kayyal, the demand-side platform’s finance chief who has been in role since August 2025 and served on its board from the February prior to that, topping off what’s been a tumultuous 12 months.

The Trade Desk’s chief accounting officer Tahnil Davis will serve as interim CFO, while the search for a more permament replacement is conducted.

The termination of such a senior executive after a short time in office raises questions – NewStreet Research’s Dan Salmon has a concise analysis – with The Trade Desk’s share price plunging 5% in the early hours after the January 2026 announcement.

The departure also echoes similar moves from other DSPs, including layoffs at challengers in the sector such as Yahoo in earlier months, with sources telling Digiday the moves were signs of a financially challenging 2025 for the sector.

A November survey from Digiday Research noted the marked rise of Amazon’s DSP, with the results showing that decline of The Trade Desk – dropping from 55% in Q1 2024, to 29% Q3, 2025 – contrasting with the rise of the e-commerce giant’s fortunes – shooting up from 29% to 50% during the same period.

Of course, the rise of Amazon contrasting with the rocky fortunes of independent DSPs helps resurface “the Open Internet vs. Wall Gardens” debate, although, a report released this month point to a wind in the sail of the latter.

According to a report from Winterberry Group, which characterizes the following 12 months as one of “continuous evolution” as opposed to runaway growth or sudden contraction, with advertising spend projected to grow to $664 billion in 2026, up 9.4% year over year when political advertising is included.

However, in a market that is stabilizing after several years of volatility, while also undergoing structural change driven by AI, marketers are being asked to “do more with the same,” per Winterberry’s researchers.

All of this means performance advertising will likely be marketers’ cause célèbre in the months ahead as their peers in the finance department ask for immediate results for their marketing investment, making the jobs of sales staff at platform-providers – read Amazon, Google and Meta, etc. – equipped black boxes primed to take further advantage.   

What we’ve heard

“According to a reputable leaker on TeamBlind; the layoffs are pushed right one day- i.e. 28 JAN 2026 [sic] is purportedly the new day. Everything else should be consistent/correct.”

— As Amazon is expected to follow up on its series of 2025 layoffs, reputedly preparing to cut 30,000 jobs, ahead of its Feb. 5 earnings call, one anonymous source forecasts the precise date the axe will fall.
