Strategy Resumes Bitcoin Buying as Fed Rate-Hike Odds Climb

Bitcoin traders woke up to two conflicting signals on September 1. On one side, the largest corporate holder of Bitcoin just came back to the market with a nine-figure purchase. On the other, Wall Street is pricing in real odds of a Federal Reserve interest rate hike this month — a scenario that would work directly against risk assets like crypto. Together, the two stories capture exactly the tension defining the US market as autumn trading gets underway.

Strategy Ends Its Ten-Week Pause With a $370 Million Buy

Strategy, the company formerly known as MicroStrategy, disclosed in a filing with the US Securities and Exchange Commission that it purchased 4,603 BTC between August 24 and August 30 for approximately $369.7 million, at an average price of roughly $80,318 per coin. The move ends a pause of more than two months, during which the firm had been a net seller of Bitcoin as it rebuilt its cash reserves and repurchased preferred shares.

The new acquisition lifts Strategy's total holdings to 845,050 BTC, acquired at a cumulative cost of about $63.73 billion and an average price near $75,412 per Bitcoin. That stake represents roughly 4% of Bitcoin's total eventual supply sitting on a single corporate balance sheet.

Executive Chairman Michael Saylor signaled the shift ahead of the filing with a post on social media reading "We're back," accompanied by a chart tracking the firm's purchase history. Strategy funded the entire buy through its at-the-market stock program, selling millions of MSTR shares rather than tapping existing reserves — a structure that also let the company reduce its outstanding STRC preferred stock and add to its unrestricted cash position. Management still has authority to sell billions more in MSTR shares under its existing offering, leaving room for further purchases if it chooses to keep buying.

Rising Fed Rate-Hike Odds Add a Counterweight

The renewed buying comes against a more cautious macro backdrop. Following Federal Reserve Chair Kevin Warsh's remarks at the Jackson Hole symposium, traders sharply repriced the odds of a rate increase at the Fed's September 15–16 meeting. CME FedWatch pricing put the probability of a hike in the high-50% range by August 31, up from roughly a third just days earlier.

Warsh did not commit to a hike outright, but his inflation commentary rattled markets: he noted that annual core inflation remains well above the Fed's 2% target, with a majority of items in the price basket still rising faster than 3% a year. Higher-for-longer rate expectations tend to lift yields on dollar-denominated assets, which can make speculative holdings such as Bitcoin comparatively less attractive.

Adding to the uncertainty, several major US economic reports — including the ISM Manufacturing Purchasing Managers' Index — are due this week and could sway the Fed's decision either way. A weaker reading would likely support hopes that the central bank holds rates steady, while stronger data could reinforce the case for a hike. Wall Street banks remain split: some, like Barclays, now expect hikes in both September and December, while others still see the Fed's next move as a cut later in the year.

What It Means for the Market

The combination gives US crypto markets a split narrative heading into September. Strategy's return to accumulation signals that at least one major institutional player still sees value in Bitcoin near current levels, reinforcing a long-term corporate-adoption thesis that has underpinned much of 2026's rally. At the same time, a genuine shift toward tighter Fed policy would be a headwind few in the market are fully prepared for after months of rate-cut optimism.

With Bitcoin trading in the high-$70,000s and several market-moving US data releases due before the Fed's mid-September meeting, the next two weeks are likely to determine whether institutional buying or macro tightening sets the tone for the rest of the year.
