Tesla stock steadies after Musk’s $2 billion xAI bet and a $20 billion spending jolt

NEW YORK, Jan 29, 2026, 09:38 EST — Regular session

  • Tesla shares barely moved in early trading, following swings triggered by earnings and spending plans.
  • Investors are balancing Tesla’s move into robotaxis and robotics with a weaker core EV market.
  • Attention is turning to cash burn, regulatory challenges, and upcoming rollout targets.

Tesla shares edged up 0.07% to $431.46 in early Thursday trading, following a close of $431.16 the previous day.

The stock’s recent jump comes amid a flurry of headlines: a new investment linked to Elon Musk’s AI goals, plus a steep increase in planned expenditures.

Here’s why it matters now: Tesla’s market value hinges largely on its bets on autonomy and robotics. That’s despite growing challenges in its car segment, where demand is cooling, prices are under pressure, and rivals are closing in.

Tesla announced a roughly $2 billion investment in xAI, the AI firm started by Musk, while reaffirming that its Cybercab robotaxi production remains on schedule. Thomas Monteiro, senior analyst at Investing.com, described Tesla as “entering a transition phase,” noting that “rollout metrics” now carry more weight than vehicle delivery numbers. 1

During the earnings call, Tesla’s ramped-up spending plans stood out. Musk described it as “a very big capex year,” referring to capital expenditures—funds allocated to factories and equipment—as the company expands production lines for the Cybercab, the Optimus humanoid robot, and other ventures. Scott Acheychek, COO of REX Financial, pointed to a “business model transition now underway” as the bigger story. 2

The steep rise in spending dampened the early rally. Tesla shares gained roughly 3.5% in after-hours trading following the earnings release, only to pull back as investors weighed the costs. On Thursday, Tesla’s shares listed in Frankfurt climbed 1.8%. 3

Tesla filed its annual report and an 8-K on Wednesday, company documents reveal, offering investors fresh details on the AI initiatives and financing strategy. 4

There’s still plenty that could derail progress. Regulators haven’t approved fully driverless cars for wide use, and Tesla is wagering big on tech that hasn’t been tested at scale. Missed deadlines or a sudden need for more funding could easily weigh on the stock again.

Tesla’s next milestones are near. In its quarterly update, the company reported 2025 revenue dipped 3% to $94.83 billion. It closed the year with $44.06 billion in cash, cash equivalents, and investments. Tesla expects its xAI investment to wrap up in Q1 2026 and plans to launch a Gen 3 Optimus in the same quarter. Production for Cybercab and Tesla Semi is set to start in the first half of 2026. 5
