Pony AI Inc's stock surged 5.14% during Tuesday's trading session, reflecting strong investor optimism following the company's latest financial results and updated guidance.

The autonomous-driving company reported first-quarter revenue of $34.25 million, representing a 145% year-over-year increase, driven primarily by explosive growth in its robotaxi business. Robotaxi services revenue skyrocketed 395.4% to $8.6 million during the quarter, while fare-charging revenue jumped more than 456.5% following the launch of the company's Gen-7 fleet.

Management significantly raised its 2026 outlook, increasing the global robotaxi fleet target to more than 3,500 vehicles from a previous goal of 3,000, and boosting the robotaxi revenue target to more than 3.5 times 2025 levels, up from a prior forecast of 3 times. The company also reported an adjusted loss of 9 cents per share, which was notably better than the 25-cent loss per share analysts had projected.
