Anniversary of August 7
On August 7, 2018, Elon Musk tweeted a 61-character message that would unleash euphoria in the markets and, at the same time, controversy with the SEC. Discover the fascinating story of how an Elon Musk tweet shook the market.
On August 7, 2018, Tesla CEO Elon Musk posted a tweet that sparked a storm in the financial world:
"I'm considering taking Tesla private at $420. Financing secured."
This message, just 61 characters long, sent shockwaves through the markets, attracted the attention of regulators, and generated scrutiny that still resonates throughout modern business history. What seemed like a casual Twitter post had enormous legal, financial, and reputational implications for Musk and Tesla.
The Context: Tesla in 2018
In 2018, Tesla faced multiple challenges. On the one hand, it struggled to increase production of the Model 3, its mass-market electric vehicle. On the other, it faced constant pressure from investors and analysts skeptical of its ability to generate sustainable profits. Added to this was growing speculation from "short sellers" (investors who bet that a stock's price will fall), who viewed Tesla as an overvalued company on the verge of collapse.
Elon Musk, known for his direct and often controversial style, regularly expressed his frustration with short sellers and criticism in the media. For him, taking Tesla private could mean escaping market volatility and short-term shareholder pressures.

The Tweet and its Immediate Repercussions
Musk's tweet was striking because it not only mentioned the possibility of taking Tesla private, but also claimed that the financing to do so was secured. According to Musk, the purchase price would be $420 per share, which represented a significant premium over the market price at the time, valuing Tesla at approximately $72 billion.
- Market Reaction
The market reacted immediately. Tesla shares soared more than 11% after the tweet, reaching $379 before trading was temporarily halted to prevent further volatility. - Confusion among Investors
The announcement didn't follow typical protocols for an official release, leaving shareholders, analysts, and regulators in a state of uncertainty. Many wondered whether Musk had actually secured the funding or if it was a maneuver to boost the stock's value and frustrate short sellers. - Tesla Board Response
Shortly after, Tesla's board of directors confirmed that Musk had discussed the idea of taking the company private, but offered no details about the alleged financing. This fueled doubts about the seriousness of the tweet.
The Key Phrase: "Funding secured"
The most controversial element of the tweet was the claim that funding was "secured." Further investigation revealed that Musk had had preliminary discussions with the Saudi Arabian Public Investment Fund, but these negotiations were far from a done deal. This was key to the development of the legal and regulatory implications of the incident.
The SEC Intervention
The Securities and Exchange Commission (SEC), the US securities regulator, opened an investigation almost immediately. According to the SEC, Musk's tweet could constitute market manipulation and securities fraud, as investors took the statement as a confirmed fact, significantly affecting Tesla's stock price.
In September 2018, the SEC filed a lawsuit against Musk for issuing false and misleading information. They argued that:
- Musk had not secured financing.
- The legal requirements for an announcement of such magnitude had not been met.
- The tweet had harmed investors, especially those who made decisions based on incomplete information.
The Settlement with the SEC
To avoid a protracted trial, Musk reached a settlement with the SEC in September 2018. The terms included:
- Economic fines
Musk and Tesla each paid a fine of 20 million dollars. - Temporary resignation as chairman of Tesla's board
Musk had to step down as chairman of the board for three years, although he remained CEO. - Increased oversight of Musk's public communications
Tesla's lawyers were required to pre-review any public statements Musk made that could affect the stock price.
Although Musk accepted the settlement, he expressed his disagreement with the SEC and continued to criticize it in interviews and on social media.

Impact on Musk and Tesla's Reputation
The incident reinforced Musk's image as an impulsive and unconventional entrepreneur. While some investors questioned his ability to lead Tesla responsibly, others saw him as a visionary willing to challenge established norms. Tesla's stock continued to be highly volatile, but interest in the company continued. In fact, many believe the controversy helped keep Tesla in the spotlight.
Lessons from the Incident
The episode left important lessons for the financial and technological world:
- The influence of social media on markets
Musk's tweet showed how a single message can significantly alter a company's value, underscoring the need for regulation in this area. - The importance of transparency
Investors need clear and verified information to make informed decisions. This incident highlighted the consequences of inaccurate statements by business leaders. - The role of regulators
The SEC's response demonstrated that even the most prominent figures can be held accountable for their actions.
Tesla's Future After Funding Secured
Despite the turbulence generated by the tweet, Tesla continued to grow. In the following years, the company achieved important milestones:
- In 2020, Tesla became one of the most valuable companies in the world, surpassing a market capitalization of 1 trillion dollars.
- Electric vehicle production increased significantly, cementing Tesla's position as a leader in the sector.
- Musk, despite his controversies, became the richest person in the world thanks to the rise in the value of Tesla shares.
Conclusion
Elon Musk's tweet of August 7, 2018, was a landmark moment in modern business history, illustrating the power and risks of social media in financial markets. While the incident generated legal and reputational issues, it also highlighted Tesla and Musk's ability to overcome adversity and redefine the automotive and technology industries. Today, that "Funding Secured" tweet remains a reminder of how innovation and impulsiveness can converge in the business world.
