Shares of MARA Holdings (MARA) tumbled in early morning trade on Tuesday after the company launched its MARA Foundation at the Bitcoin 2026 Conference the day before
Chief executive Fred Thiel said the foundation's goal is to support Bitcoin’s (BTC) long-term growth beyond mining through research, education, and open-source development.
He added that the foundation will focus on key areas like Bitcoin security, which includes quantum resistance research, as well as open-source development, global self-custody tools, policy advocacy, and Bitcoin education for developers and regulators.
MARA’s stock fell over 3% in pre-market trade, with retail sentiment on Stocktwits around the company trending in ‘bearish’ territory over the past day and chatter at ‘high’ levels. MARA was among the top trending tickers on the platform at the time of writing.

Some traders on Stocktwits expressed their frustration against the CEO for "giving away" money while the stock price was struggling. MARA shares were up more than 20% year to date but remain down over 22% over the past 12 months.
MARA's dip comes alongside weakness in the equity and cryptocurrency markets. Bitcoin’s price tumbled nearly 2% in the last 24 hours, trying to hold above its key support level of $76,000. Retail sentiment around the apex cryptocurrency on Stocktwits trended in ‘bullish’ territory over the past day, accompanied by chatter at ‘normal’ levels.
Thiel also announced a $100K community grant vote in which the Bitcoin community will choose one of three organizations. The first option he gave was the 256 Foundation, which funds open-source Bitcoin mining hardware and software as well as developer education.
The other two were the Libreria de Satoshi, which aims to spread BTC technical education globally in multiple languages, and SateNet, which builds community-run internet networks in the Global South using BTC support.
On the balance sheet, MARA holds roughly 38,689 BTC, placing it among the largest institutional Bitcoin holders. It trails Strategy (MSTR), which holds over 818,000 BTC, as well as other corporate holders and Twenty One Capital XXI, which holds 43,514 BTC.
The announcement comes as MARA transitions from a pure-play Bitcoin miner to powering data center operations. On Monday, Morgan Stanley raised its price target on MARA Holdings to $8.50 from $8 but maintained an ‘Underweight’ rating.
