Why is Pony AI stock rising today?

Pony AI's stock price surged 5.5% to HK$61.85 today as investors returned after a three-day decline triggered by the company's Q2 earnings. Despite the recent drop, market participants appeared to re-evaluate the results more positively, particularly the significantly smaller-than-anticipated adjusted loss and a surge in robotaxi revenue.

The primary catalyst for the recovery today is the live rollout of Pony.ai's autonomous rides in Zagreb, Croatia, marking the first European deployment accessible through the Uber app. This development provides concrete evidence of the company's recent announcements of over 2,000 robotaxis set to be deployed across five European cities in partnership with Uber, with total international vehicles under discussion reaching more than 4,000.

The broader market sentiment on the day also favored risk assets, particularly technology, following a drop in U.S. Treasury yields overnight. The Hang Seng index climbed 0.8% during this period.
