Tesla, Inc., TSLA

The broader market gave Tesla a tailwind. The S&P 500 gained 0.2% on the day, moving toward a new intraday all-time high. The Nasdaq Composite added 0.5%. Investor sentiment was lifted by expectations that the Iran conflict may be approaching a resolution.

But Tesla had its own story to tell.

Elon Musk announced on social media that the company’s AI chip design team had completed the “tape out” of the AI5 self-driving chip. He called it a key milestone as the chip moves into manufacturing, and thanked Samsung and TSMC for their production roles.

Musk said AI5 could become “one of the most produced AI chips ever,” with high-volume production expected in 2027. The chip is designed to eventually replace the AI4 chips currently used in Tesla vehicles. He also mentioned a potential tape-out for the next-generation AI6 chip as early as December 2026.

Wall Street Weighs In

Not everyone was rushing to pile in.

Barclays analyst Dan Levy reiterated an Equalweight rating with a $360 price target. He noted Tesla’s fourth-quarter results marked the end of Model S and Model X production — a sign the company is pivoting away from traditional car-making toward what it calls “Physical AI.”

Levy outlined Tesla’s ambitious plans: a proposed “Terafab” facility with 1 terawatt of AI computing capacity — roughly 50 times current global AI compute — and a goal to build 100 gigawatts of solar capacity. Barclays estimates the Terafab alone could cost trillions of dollars.

Despite the vision, Barclays flagged limited visible progress on Robotaxi, Full Self-Driving, and the Optimus humanoid robot program.

UBS moved differently. Analyst Joseph Spak upgraded Tesla to Hold from Sell, keeping a $352 price target. Spak said current price levels “more evenly balance” near-term risks, but warned the stock may stay volatile — driven more by sentiment than fundamentals.

UBS projects Tesla vehicle deliveries of around 1.6 million units in 2026, roughly flat year-over-year, before a 7% compound annual growth rate brings it to about 2 million by 2030. That’s well below broader market estimates of 3 million.

Valuation Still a Talking Point

Tesla’s P/E ratio sits at 363x on a trailing twelve-month basis — 238% above its five-year median of 107.4x. GuruFocus places fair value at $254.36, putting the current price at a 54% premium.

Insider activity adds another layer. Over the past three months, insiders sold $20.9 million worth of stock with no recorded purchases on the other side.

Tesla is still down 19% year-to-date, compared to a 2% gain in the S&P 500 over the same period.
