Trade Desk Inc. (TTD) shares jumped more than 19% on March 5, 2026, following secondary reports linking the rally to insider buying and speculation about a potential OpenAI partnership. No SEC filings or company statements in the prior 72 hours confirmed these claims.
Surge and Insider Activity Discrepancies
The sharp intraday surge coincided with widespread secondary reporting attributing the move to insider trading and OpenAI partnership rumors. However, public records show no insiders purchased shares in the past 12 months. Instead, five insiders sold a combined $14.17 million, leaving insider ownership at roughly 10.0%. No Form 4 filings supported recent insider purchases, creating a clear conflict between the reports and official disclosures.
Earnings, Guidance, and Buybacks
The company’s Q4 2025 earnings, released on February 25, 2026, showed revenue growth of 19% year over year excluding political advertising and 14% including it. Adjusted EBITDA for the quarter was $400 million, or 47% of revenue. Operating cash flow reached $312 million, with free cash flow at $282 million. Connected TV remained the strongest growth driver.
For Q1 2026, Trade Desk guided revenue of $678 million, about 10% higher year over year, and adjusted EBITDA of $195 million. The company expects its full-year 2026 adjusted EBITDA margin to remain flat compared with 2025. Management indicated revenue growth should improve over time despite short-term headwinds from tariffs and competition.
The balance sheet showed $1.3 billion in cash and no debt as of the quarter. The company repurchased $423 million of stock in Q4 2025 and authorized an additional $500 million for buybacks, which it plans to use opportunistically to offset dilution.
The surge came after a weak start to 2026, with shares down 37% year to date and among the S&P 500’s worst performers. Some analysts described the recent earnings call as lacking conviction and highlighted competition from Amazon. The conflicting insider activity reports and absence of primary confirmation complicate interpreting the rally as either fundamentals-driven or rumor-based.
