Tether has been buying 15% of its profits in Bitcoin since May 2023. Past inflows have been between 700 million to 1.4 billion dollars and they have had a tendency to coincide with markets of uncertainty. This recent addition can be seen as a legacy of that strategy according to analysts. Tether has an estimated unrealized profit of approximately $5.5 billion based on an average price of purchase of Bitcoin in its holdings of about 10 million Bitcoins at an average purchase price of $48542.

Stablecoin inflows strengthen USDT dominance

This is purchased as Tether remains the market leader in the stablecoin market. In 90 days, stablecoins had net inflows of over 45 billion, and Tether comprised of 19.6 billion. That provides USDT with a market share of approximately 59, to stay significantly ahead of its competitors.

Q3 inflows were a continuation of Q2, where Tether had minted 9.2 billion of new USDT. The market cap of the company is currently at 115.2 billion with the support of the 127 billion US Treasuries, and 5.47 billion excess reserves. The USDC of Circle also saw significant expansion, and the inflows reached 12.3 billion versus 500 million in the third quarter of the year.

Institutional demand is very robust, with ETFs controlling 410,000 BTC, or 33 percent of U.S. ETF offerings, and publicly traded companies controlling 725,000 BTC. Such demand exceeds the annual issuance of Bitcoin. Bitcoin was trading at $113,184, a day to the down by 0.67 percent, as of September 30.
