Pony AI stock has fallen sharply year to date, yet the valuation checks still suggest the shares are not a clear bargain. This is an unusual combination that investors will want to unpack carefully.

• Year to date, Pony AI has declined 51.8%. Anyone buying earlier in 2026 is sitting on a sizeable loss and the stock is now being reassessed by the market.
• The planned deployment of more than 2,000 robotaxis in Europe and a possible expansion to the Middle East can support long term revenue expectations. At the same time, execution risks around large scale autonomous rollouts may weigh on how much value investors are willing to assign today.
• Pony AI scores 2 out of 6 on the broader valuation checks. This points to a stock that leans expensive rather than a clear bargain on traditional measures such as multiples and cash flow quality, even after the recent share price fall.

The issue now is whether Pony AI's current share price already reflects the risks around its robotaxi ambitions or still embeds expectations that may be too optimistic for the fundamentals to support.

Does Pony AI Look Pricey on Sales?

P/S is often a cleaner way to look at a high growth software and mobility stock like Pony AI where earnings are not yet a key anchor. On this measure, Pony AI trades on a P/S of 26.9x, compared with a software industry average of 3.9x and a peer group average of 5.5x. That is a very large premium to both broad sector norms and closer comparable companies.

The fair P/S ratio from the model is 7.5x. This is already tailored to Pony AI’s revenue profile, scale and risk, yet it still sits far below the current 26.9x. The gap is so wide that the output is better read as a warning that the framework sees the stock as screening very expensively rather than as a precise target. Despite the recent robotaxi partnership with Uber lifting interest in the story, the present P/S level still asks investors to pay a high price for each dollar of Pony AI’s sales.

On the preferred P/S yardstick, Pony AI stock currently appears significantly more expensive than the levels indicated by the model.

Bull case: 23% undervalued

"Long term technology advantages in world model based closed loop training, a 70% reduction in autonomous driving kit BOM cost for both Gen 7 robotaxis and Gen 4 robotrucks, and strong global OEM and platform partnerships across eight countries position Pony AI to benefit disproportionately from secular adoption of autonomous mobility, which could drive sustained revenue growth and margin expansion..."

Bear case: 115% overvalued

The Bottom Line

Pony AI still screens as overvalued on the preferred P/S yardstick, even after a steep year to date share price decline. The gap between the tailored fair multiple and where the stock currently trades reflects how much optimism the market is placing on long term robotaxi deployment and monetisation. For you as an investor, the key question is whether Pony AI can turn its partnerships and technology into profitable scale quickly enough to justify paying such a premium today, or whether execution risks around large autonomous fleets keep that premium exposed to disappointment.
