The share increase of Sportradar

Sportradar’s 4% gain may have been supported by continued investor reaction to its expanded partnership with Polymarket, announced on August 27. The agreement extends Sportradar’s data, streaming and integrity services across more than 20 sports leagues and competitions and around 300,000 matches annually, strengthening its position in the growing prediction-markets segment.

The decline of Gentoo Media shares

Gentoo Media’s decline continued after its Q2 results disappointed investors and the company cut its full-year outlook. Revenue fell 9% year-on-year to EUR 22.9 million, while 2026 revenue guidance was lowered to EUR 97–100 million from EUR 105–115 million, keeping pressure on the shares into the following week.
