Why is Trade Desk Stock Surging Today?

The primary reason why TTD stock outshined its peers on Thursday was due to the largest insider trading announcement. Precisely, Trade Desk CEO Jeffrey Terry Green purchased 6.4 million TTD shares at $22.93 and $25.25 per share, for a whopping $148 million, between March 2 and 4.

Remarkably, the massive insider trading coincided with reports of OpenAI talks to automate ChatGPT as sales through TTD’s platform. With OpenAI seeking to monetize its more than 200 million weekly users, the reports of a potential partnership with the Trade Desk sparked traders’ optimism.

What’s the legality of TTD insider trading?

While the move from Green signaled a strong executive confidence, TTD traders are concerned about whether the United States Securities and Exchange Commission (SEC) will take legal action. However, the SEC’s filing of the insider trading will unhook Green’s move from potential SEC’s legal action.
