Elon Musk Buys Tesla Stock for First Time Since 2020 — Confidence Is Back

What Happened

On Friday, Elon Musk made headlines by purchasing around 2.57 million Tesla shares in multiple open-market transactions.

  • Total value: Roughly $1 billion
  • Price range: Between $371 and $396 per share
  • First buy since 2020: This marks Musk’s first open-market Tesla stock purchase since February 2020.

This was disclosed in a regulatory filing and instantly caught the attention of Wall Street and retail traders alike.


Why It Matters

  • Confidence signal: CEO stock purchases are often read as bullish indicators. Musk is showing conviction that Tesla is undervalued or entering a new growth phase.
  • Stock reaction: Shares jumped more than 5–7% after the disclosure, reflecting renewed investor optimism.
  • Strategic timing: Tesla is doubling down on AI, robotaxis, and robotics, and this move strengthens the perception that Musk is betting big on Tesla’s future.

What It Means for Investors

Key Point Why It Matters
First open-market buy in 5 years Shows Musk’s renewed public confidence in Tesla’s outlook.
$1B purchase size Symbolic in scale — meaningful for sentiment, less so for voting control.
Price range ($371–$396) Suggests Musk sees value in this zone; becomes a reference point for traders.
Alignment with compensation goals Musk has ambitious performance targets; buying shares ties him even closer to execution.
Volatility remains Even with insider buying, Tesla still faces risks from competition, regulation, and macroeconomics.

My Take — Why I’m Bullish

Tesla is my favorite stock at the moment, and this buy only reinforces my conviction.

Back in April, after Tesla dipped post-earnings, I reminded investors to think bigger. Tesla is not just a car company. Read Article here from April 23, 2025 TESLA HITS A SPEED BUMP - TIME TO HIT BUY?

They are building in:

  • AI — powering autonomous driving and future robotaxi networks
  • Robotics — Optimus humanoid robot projects and automation in manufacturing
  • Energy & storage — solar, battery technology, and grid-scale solutions
  • Auto — still a market leader in EV innovation and scale

When you look at the big picture, Tesla is positioning itself as a multi-industry technology powerhouse — not just an automaker.

That’s why I remain BULLISH TESLA and believe the best is yet to come.


What to Watch Next

  1. Share price action — Does Tesla hold its gains after this news, or fade lower?
  2. Progress toward goals — Production, robotaxis, AI, and robotics execution will be key.
  3. Competitor landscape — EV, AI, and robotics competitors could shift sentiment.
  4. Macro and regulatory factors — Interest rates, subsidies, and trade tensions remain risks.
  5. More insider activity — Additional stock buys could reinforce confidence.

Bottom Line

Elon Musk’s $1 billion Tesla purchase is more than just a transaction — it’s a statement. After years without buying, Musk is signaling he believes Tesla’s next chapter is bright.

For new investors and traders:

  • It’s a positive sentiment shift, but not a guarantee of success.
  • Use it as a chance to dig deeper: is Tesla’s valuation compelling at current levels?
  • Think in scenarios — what happens if Tesla misses, and what happens if it massively over-delivers on its AI and robotics vision?

Musk has put his money back on the table. And for me — this remains my favorite stock with big things ahead. Tesla is more than cars — it’s AI, robotics, energy, and autonomy all in one. BULLISH TESLA.
