Good Morning Blocksignal Community,
Executive Summary
Bitcoin broke back above $85,000 on Monday for the first time since January, a short squeeze on top of a broader risk-on mood in equities and oil that capped the best quarter for bitcoin since late 2024. Corporate treasuries kept buying through the move: Strategy and Strive both added bitcoin, and Bitmine chairman Tom Lee called the current stretch a bull market while his firm pushed closer to owning 5% of all ether. On the political side, crypto's largest PAC opened its most aggressive midterm spend yet, committing $30 million against a Clarity Act opponent days after the bill failed a Senate procedural vote.
Market action & drivers
Bitcoin opened Monday near $81,200 and climbed to an intraday high of $85,134, a gain of more than 5% in 24 hours and the highest level since January. The move built on a recovery from a mid-September low near $75,000 and left bitcoin up 44% for the third quarter, its strongest three months since the fourth quarter of 2024 and well ahead of gold (up 8.7%) and the S&P 500 (up 2%) over the same stretch. Bitcoin closed the week above its 50-week moving average for the first time in 45 weeks, a level some traders watch as a marker of trend change, though it says nothing on its own about what happens next. Ether traded up 5.6% to $2,717, XRP rose 7.8% to $1.49, and Solana gained 7.2% to $115.75. Analysts pointed to a mix of causes rather than one clean story: Asian and European equities advanced, oil fell around 1.5% on expectations Saudi Arabia would restore damaged pipeline capacity, and oversold positioning after the mid-September selloff left the market primed for a squeeze once buyers stepped back in.
Derivatives & positioning
The move higher forced a wave of short covering. CoinGlass recorded roughly $750 million in liquidations across crypto markets over 24 hours, with $648.3 million of that on short positions. Bitcoin alone accounted for $360.7 million of the liquidated positions, including a single $11.3 million order on Binance's BTCUSDT pair. That skew toward shorts is consistent with a squeeze rather than a broad shift in conviction, and it cuts both ways: the same mechanics that accelerated Monday's rally can accelerate a pullback if momentum stalls.
Adoption & industry
Corporate accumulation continued on both sides of the bitcoin/ether split. Strategy bought 950 BTC for about $75.7 million between September 14 and 20, taking its total to 846,000 BTC — over 4% of bitcoin's fixed 21 million supply. Strive added 1,355 BTC for roughly $107.7 million over a similar window, bringing its holdings to 26,355 BTC as it chases a self-set goal of becoming the second-largest corporate bitcoin holder by year-end. On the ether side, Bitmine bought 27,562 ETH in the past week, pushing its stake to roughly 4.9% of circulating supply and about $16.3 billion in value; chairman Tom Lee described a "crypto bull market" underway since late June, pointing to rotation out of AI trades and what he called strengthening fundamentals. That is Lee's read on the market as the head of a firm with a direct stake in ether's price, not a neutral data point, and Blocksignal treats it as one voice among many rather than as guidance. Separately, Coinbase opened IPO share allocations to eligible US retail customers for the first time, starting with wearables maker Oura, extending its push beyond trading into primary securities offerings.
Regulation
The Clarity Act, which would have set a federal regulatory framework for crypto, failed a Senate procedural vote last week after Democrats objected that President Trump stood to personally benefit from crypto ventures under the bill as written. In response, the industry PAC Fairshake committed $30 million to campaign against former Senator Sherrod Brown, a longtime crypto skeptic, ahead of Ohio's November midterm race — the PAC's most aggressive single commitment yet, with more spending expected in the weeks ahead. It is a marker of how much political capital the industry is now willing to spend on individual races, not a signal about whether the Clarity Act itself will eventually pass.
Today's Watch
The SEC's tokenized-securities pilot framework, which lets qualified venues facilitate secondary trading of tokenized US stocks on public blockchains, opens today. A roughly $51 million TON token unlock is also scheduled for today. Price momentum extended into the early hours, with bitcoin briefly touching the high-$86,000s to low-$87,000s on continued short covering — worth watching for two-way volatility given how much of Monday's move was liquidation-driven rather than fresh buying. Later this week: a possible Trump-Xi meeting Thursday (timing unconfirmed), US jobless claims and new home sales data Thursday, and durable goods orders plus the Michigan consumer sentiment index Friday. With leverage and liquidations elevated, this is a week to watch position sizing rather than chase the move.
