Elon Musk, never one to miss a chance for a bit of market theater, just gave the "Inverse Cramer" meme his unofficial seal of approval. The Tesla Inc. (TSLA) CEO took a playful swipe at CNBC host Jim Cramer on Monday, reacting with a laughing emoji on X to a 16-year-old video clip.

In the vintage clip, Cramer is seen writing off Tesla as a sound investment. Musk’s response wasn't just a trip down memory lane; it was a direct nod to the "Inverse Cramer" phenomenon. The idea is simple, if a bit cheeky: if Jim Cramer says something is going to happen in the markets, bet on the opposite. The meme posits that this contrarian approach can lead to significant profits.

Musk didn't stop there. In another post, he took a dig at Cramer's more recent prediction of no de-escalation in U.S.-Iran tensions. "Phew, now I can rest easy…Inverse Cramer is incredible," Musk wrote, clearly enjoying the bit and further cementing the idea that the opposite of Cramer's forecasts has a habit of coming true.

Tesla's Trillion-Dollar Rebuttal

The timing of Musk's comments adds another layer. They came as crude oil prices spiked above $100 amid escalating Middle East tensions. Cramer himself had warned late Sunday that "A sudden oil shock is always bad for stocks," adding, "I don't see a path to de-escalation." He expressed skepticism, fearing a repeat of 2022 or "worse."

But the real punchline to the 2010 video is Tesla's performance. When Cramer expressed his doubts, Tesla's market cap was under $2 billion. Fast forward to today, and the electric vehicle maker has soared to a valuation well over $1 trillion. It's the kind of growth that makes a 16-year-old skeptical take look, well, inversely prophetic.

The Meme With Momentum

The "Inverse Cramer" idea isn't just a joke among online traders anymore; it's gained real traction as a concept people are actually tracking. Earlier this year, a report from a tracker following Rep. Nancy Pelosi's (D-Calif.) stock picks—often seen as a strong market indicator—stated, "The Queen has been dethroned. Inverse Cramer officially beats out Pelosi for the top portfolio on Autopilot." The report noted that in 2025, the strategy of investing opposite to Cramer's picks had outpaced the trades made by Paul Pelosi, which are typically strong performers.

And it's not just stocks. In late November, Cramer warned that a recent bounce in cryptocurrency "makes no sense" and highlighted risks in leveraged positions. Contrary to that warning, Bitcoin (BTC) proceeded to surge nearly 6.8% over the next five days, climbing from around $85,973 on Nov. 21 to roughly $90,473 by November 26.

So, what are we left with? A billionaire CEO having a laugh at an old TV clip, a popular market meme that keeps finding new examples to fuel it, and the enduring question of whether the loudest voice on financial TV is a reliable indicator—just in the wrong direction. It's a reminder that in the markets, sometimes the biggest returns come from betting against the conventional wisdom, especially when that wisdom is being broadcast to millions.
