Shares of companies involved in Bitcoin mining and AI infrastructure surged, causing losses for short sellers. On Thursday, July 30, 2026, Keel Infrastructure (formerly Bitfarms) led the gains, rising 29.13%, followed by Nebius Group, Cipher Digital, and IREN Limited with jumps over 27%. Other notable gainers included Riot Platforms, Bitdeer, Core Scientific, Hut 8, and Cleanspark, with increases mostly ranging from 17% to 24%. The rally was attributed to a short squeeze triggered by a hedge fund's forced liquidation of its holdings, which were largely bought by Citadel. Additionally, Bitcoin trading above $64,000 and strong Microsoft earnings, highlighting AI's profitability, boosted market sentiment. Coreweave also announced a deal to provide AI cloud services for U.S. defense and intelligence agencies. This surge reflects a broader, longer-term trend of Bitcoin miners pivoting to AI data centers, leveraging their existing energy infrastructure and land. Recent multi-billion dollar deals by companies like Hut 8, IREN, and Terawulf for AI cloud services underscore this strategic shift. Other gainers, including Sandisk, Micron, Bloom Energy, and Cerebras, are suppliers critical to the AI infrastructure build-out. While the rally provided relief after July's losses, questions remain about capital expenditures, power availability, and long-term AI demand. The sustainability of these gains depends on these companies successfully converting their energy contracts and AI service deals into stable revenue streams.

Bitcoin briefly reclaimed the $65,000 level on Thursday, continuing a gradual recovery fueled by the Federal Reserve's decision to pause interest rate hikes. The price action was volatile following the announcement, dipping to $63,199 before a sustained rally to a daily high of $65,100. Although the move solidified a monthly gain exceeding 10% for July, profit-taking later pulled the price back to around $64,700. The broader crypto market saw over $243 million in leveraged position liquidations in the past day. Beyond monetary policy, markets digested U.S. macroeconomic data including 1.5% Q2 GDP growth and a 3.2% rise in the core PCE index, signaling persistent household demand. However, ongoing Middle East geopolitical tensions, highlighted by recent Iranian strikes, pose an inflation risk by potentially pushing crude oil above $90 per barrel. Sustained high oil prices could lead to renewed inflationary pressure, increasing the likelihood of further Fed tightening—a potential headwind for risk assets like Bitcoin.

Coldcard manufacturer Coinkite has issued a security alert after reports surfaced of a coordinated loss of approximately 594 BTC (worth around $38 million) from numerous old, single-signature addresses on July 30, 2026. CEO Rodolfo Novak stated the company is prioritizing the investigation, though it has not officially confirmed a direct link to Coldcard devices. Preliminary findings indicate a potential vulnerability affecting Coldcard Mk3 devices that generated seeds using firmware versions from 4.0.1 (March 2021) to 5.0.3. Mk4, Q, and Mk5 models are reportedly not affected. The suspected issue relates to weak randomness in seed generation on some older Mk2 and Mk3 firmware, not a supply chain compromise. Coinkite notes wallets protected by a user-set BIP-39 passphrase appear at minimal risk. For vulnerable Mk3 users not using a passphrase, the company recommends migrating funds to a new seed generated on an unaffected device, advising caution and test transactions first. As temporary measures for those with only an Mk3, Coinkite suggests either setting a strong BIP-39 passphrase and moving funds, or generating a new seed via the device's "dice roll" import method, which bypasses its internal random number generator. A full technical analysis is pending as the investigation continues. The incident has drawn significant attention within the Bitcoin community given Coldcard's reputation as a secure, air-gapped hardware wallet.

In July 2026, U.S. spot Bitcoin ETFs posted their worst performance since their January 2024 launch, attracting a net inflow of only about $204.67 million according to SoSoValue. This starkly contrasts with July 2025, which saw inflows exceeding $6 billion. The month's performance was uneven, with a seven-session mid-month period drawing nearly $1 billion and marking the first three consecutive weeks of inflows since early May. However, major outflows of $225 million and $240 million on July 23 and 24, respectively, erased most of these gains. Despite being the weakest month on record, July still ended with a net positive inflow. This followed two months of significant outflows: $2.43 billion in May and a record $4.51 billion in June. From early May to late June, these ETFs lost over $8.2 billion over eight consecutive weeks of outflows. The total net assets for all U.S. spot Bitcoin ETFs now stand at approximately $77.46 billion. This represents a decline of roughly half from the peak of $150 billion recorded in September 2025.
