Talent watch: Polymarket hires CFO as Channel 4 cuts jobs

The latest round up of people moves include Polymarket, Allwyn, Omnicom, and Puma.

Polymarket has hired former finance veteran Warren Jenson as its first chief financial officer role.

This is the latest in a number of appointments made by Polymarket as it looks to compete with prediction market rivals in the US such as Kalshi.

Jenson was an early builder of Amazon, and he brings extensive experience from the finance sector, having held positions in some of the biggest US companies, including Delta Air Lines, and Electronic Arts.

Channel 4 announces largest round of layoffs ever

Channel 4 is set to make huge layoffs with roughly 300 jobs cut – equivalent to roughly a quarter of its workforce.

The restructure is the most dramatic in the organisation’s history. Chief executive, Priya Dogra, told staff the cuts came as part of a new strategy and structure.

This follows a huge round of layoffs just two years ago, when around 200 jobs were cut in what was, at the time, the biggest round of layoffs for 15 years.

Channel 4 experienced a pre-tax loss of £10m in 2025, which makes it the third annual loss in a row after a £12m deficit in 2024, and a £52m loss in 2023.

Advertising revenue fell by 2%, and total revenue dropped by 1% to just over £1bn in the last year.
