Tether has added another major block of Bitcoin to its reserves. As per reports, the USDT stablecoin issuer completed a $1 billion purchase on September 30, the final day of the third quarter.
The transaction marks one of the largest inflows this year for Tether. At a price of roughly $113,000 per coin, the company secured 8,888.889 BTC. This move reflects Tether’s pattern of making bold reserve allocations at critical financial reporting periods.

Observers noted that the purchase carried symbolic weight. Tether has a long history of using round or repeating figures when allocating reserves, often to highlight financial milestones. Market analysts added that such transactions tend to reinforce confidence across the market. For instance, one X (formerly Twitter) user namely Solano, wrote: “That explains the pump.”
Tether’s purchase of $1 billion-worth of Bitcoin comes at a time when uncertainty is peaking across the crypto market. In particular, Bitcoin is trading at $113,300 level as volatility from ETF approvals prevail in the market. Tether has on several occasions intervened with huge Bitcoin purchases at such times, enhancing its contribution to stabilizing influence on its dollar-pegged stablecoin USDT.
Tether’s Expands Its Bitcoin Reserves
Tether’s Bitcoin reserve has grown steadily over the past two years. The USDT stablecoin issuer disclosed in its June 30 attestation report that it held nearly $9 billion worth of BTC at the end of the second quarter (Q2) of 2025. The new $1 billion purchase pushes that total up by roughly 11%.
The latest purchase increased BTC’s share of Tether’s reserves, surpassing gold in relative size and approaching a double-digit percentage share of its balance sheet. Unlike traditional bonds or commercial paper, BTC gives Tether exposure to an asset class that can rise significantly in value during periods of inflation or monetary tightening.
On-chain history confirms this pattern. Tether has often injected big amounts of Bitcoin into its reserves, with transactions typically ranging between $700 million and $1.4 billion. All these acquisitions occurred at a time when there was a liquidity or regulatory issue that put pressure on the crypto market. The strategy has so far paid off, allowing the company to show robust profits even while maintaining the dollar peg of USDT.
‘Tether Could Eclipse Saudi’s Aramco,’ Says Bitwise CIO
Beyond reserve growth, Tether’s business trajectory has caught the attention of institutional investors. In a memo dated September 29, Bitwise Chief Investment Officer Matt Hougan suggested that Tether could soon become the world’s most profitable company.
Hougan argued that Tether’s explosive growth, if sustained, might even eclipse Saudi Aramco’s 2024 record. The Saudi oil giant reported $120 billion in annual profit, the highest ever achieved by a corporation. According to Hougan, Tether’s model could deliver higher earnings if its assets reach the $3 trillion mark. That figure would represent about 3% of the global money supply.
Hougan’s statements stem from reports that Tether was aiming to raise capital at a valuation of $500 billion, which highlights the extent of its expansion ambitions.
8/ I was reminded of this phenomenon recently when news broke that stablecoin issuer Tether was trying to raise money at a $500 billion valuation. This would make Tether one of the most valuable startups in the world, in line with OpenAI and SpaceX.

The $1 billion Bitcoin purchase thus indicates that Tether is committed to expanding its reserves as well as solidifying the foundation of its USDT stablecoin. If the company reaches the level predicted by Bitwise’s Hougan, it could rival not only crypto firms but also the biggest corporations in the world.
