You pose a very good, timely question. There are indeed bullish signals for Tesla, Inc. (TSLA) — but whether it can reach or exceed its prior high around US$ 488 by year-end is less certain. Below is a balanced assessment of the upside potential — plus the risks.

✅ What speaks in favour of a rally

Strong China sales momentum. Tesla’s China-made electric-vehicle deliveries in November reportedly rose ~9.9 % year-on-year — the biggest growth in over a year. That helps reaffirm demand in one of its most important markets.

Government tailwinds on robotics/AI. The new push by the United States Department of Commerce (and broader U.S. administration) to accelerate robotics — including an anticipated executive order — has revived investor interest in Tesla’s non-automotive bets. 

The “Optimus / robot + AI” optionality remains a potent wildcard. Tesla’s humanoid robot project Optimus is being re-emphasised by markets as a major long-term value driver. Some analysts have even modelled substantial future revenue from robotics, which could support lofty valuations. 

Recent technical & sentiment rebound. The stock recently found support around the mid-US$ 420s, and surged ~4 % following the robotics-push news — signalling renewed bullish momentum among some investors. 

Valuation models by some bulls target > US$ 500. As per a recent analyst note, one firm projects a share-price target around US$ 548 on optimised robotics + robotaxi + core business assumptions.

⚠️ Why hitting US$ 488 (or higher) by year-end could remain challenging

Robotics & robotaxi remain speculative. While “optional value” like Optimus and autonomous driving is alluring, it currently contributes little to revenue, and commercial scale remains unproven. 

Automotive business under pressure. Despite the uptick in China, Tesla faces stiff competition globally — and reports indicate pressure on margins, declining regulatory-credit revenue, and weaker demand in other regions. 

Valuation already reflects “future hope.” The current share price likely already incorporates a considerable premium for AI/robotics potential. Achieving ~8–10 % upside to US$ 488 would require not only bullish sentiment to persist, but robust execution — especially on the non-car front.

Time is short. We are in early December; for a move from today’s ~US$ 455 to US$ 488 requires a ~7 % rise. That’s not impossible — but it will depend on favourable news (e.g. strong December China sales, clear roadmap for robot/prod launches, or macro tailwinds) before 2026 begins.

🔎 Final view

Yes — there is a credible path for Tesla to rally toward or even slightly beyond US$ 488 by year-end, particularly if investors buy heavily into the “robotics + AI future” narrative on top of improving core sales. The convergence of strong China demand, U.S. robotics policy tailwinds, and renewed investor optimism about Optimus and robotaxi gives the stock a plausible shot at a rally.

That said, this would amount to a “bull-case rally” rather than a baseline expectation — it hinges on more than just favourable sentiment. If execution or news disappoints, the rally could stall or reverse.
