Frederick G. Thiel, CEO of Marathon Digital Holdings (MARA), has demonstrated a consistent pattern of selling activity in the company’s stock, with no recorded purchases across 24 Form 4 filings since mid-2025. His transactions, totaling over $9.6 million in sales, have been concentrated exclusively in MARA shares, with the most recent sale occurring on March 17, 2026, for $252,495. The filings reveal a mix of open-market sales (coded "S") and dispositions due to tax withholding obligations (coded "F"), with the latter accounting for some of the largest transactions, including a $685,170 disposition on February 20, 2026, and a $737,888 disposition on November 3, 2025.
The pace of Thiel’s selling has remained steady, with 10 sales recorded in the most recent six-month period. Notable open-market sales include $538,272 on October 17, 2025, and $478,036 on September 17, 2025, while tax-related dispositions peaked at $670,208 on August 6, 2025. The absence of any buy transactions suggests a one-sided liquidity strategy, though the reasons behind the sales—whether for diversification, tax planning, or other purposes—are not disclosed in the filings. The activity underscores a clear divestment trend, with Thiel systematically reducing his MARA holdings over time.
