# Bitcoin Miners Plummet Amidst Sharpest Wall Street Selloff Since July Hotter inflation data triggers a broad market decline impacting AI infrastructure and crypto miners. - **Source:** [Cointelegraph.com News](https://brifing.si/source/2e81e982-0137-4db0-8ac2-351f37085775) - **Published:** 2026-10-15 - **Topic:** [Finance](https://brifing.si/c/finance) - **Original article:** - **On Brifing:** https://brifing.si/s/31f16c86-f5fd-400e-a3cb-63addb174e89 ## Market Selloff Triggers US stocks experienced their sharpest decline since July on Wednesday, driven by hotter-than-expected inflation data. The S&P 500 dropped 1.1%, while the Nasdaq Composite fell 1.9%. This broader market downturn significantly impacted technology and AI infrastructure companies, creating a ripple effect that extended directly into the Bitcoin mining sector throughout the trading session. ## Bitcoin Miners Hit Hard Bitcoin miners faced substantial losses, with several firms dropping over 12% in a single day. TeraWulf led the decline with a 12.64% fall, followed closely by Core Scientific at 12.44%, Cipher Mining at 12.35%, and IREN at 12.2%. Other major players like Riot Platforms, Bitdeer, MARA, and CleanSpark also recorded significant daily valuation losses. ## AI Infrastructure Correlation The selloff heavily targeted companies operating within the AI infrastructure space. Data center operator CoreWeave fell 16%, while Nebius dropped 11% and Oracle declined 9%. According to the PRISM AI Data Center and Infrastructure Index, 21 out of 23 tracked stocks declined, showing an average loss of 7.46% across the sector during the trading day. ## Inflation Data Impact US consumer prices rose 3.7% in September compared to the previous year, surpassing the 3.6% expectation and remaining well above the Federal Reserve's 2% target. Analysts attributed this spike primarily to rising gasoline prices resulting from ongoing conflicts in the Middle East, which intensified concerns regarding persistent inflationary pressures across the domestic economy. ## Interest Rate Pressures Higher interest rates pose a specific threat to AI infrastructure companies that rely heavily on debt to finance massive data center expansions. Increased borrowing costs directly impact the profitability and growth projections of these capital-intensive firms. Consequently, market participants are re-evaluating the valuation of miners that have recently pivoted their business models toward AI. ## Fed Policy Expectations The latest inflation report fueled market expectations for a potential interest-rate hike in October. The implied probability of such a move briefly exceeded 50% on Wednesday before retreating slightly. Investors are closely monitoring these shifts, as the cost of capital remains a critical factor for companies managing high debt loads in the current environment. ## Fed Stance on Urgency San Francisco Federal Reserve President Mary Daly indicated that while further rate hikes might be necessary to control inflation, there is no immediate urgency to act this month. Daly emphasized that the Fed has sufficient time to evaluate incoming data before making definitive policy decisions, aiming to avoid hasty actions based on limited information sets. ## Strategic Market Outlook The convergence of Bitcoin mining and AI infrastructure has created a new risk profile for investors. As miners expand into data centers, they become increasingly sensitive to macroeconomic indicators like CPI and interest rates. Future performance will depend on how these firms manage debt-fueled growth while navigating a volatile interest rate environment and inflationary pressures. ## Sources covering this story - https://cointelegraph.com/markets/bitcoin-miners-plunge-up-to-13-in-wall-streets-worst-selloff-since-july?utm_source=rss_feed&utm_medium=rss&utm_campaign=rss_partner_inbound — --- _Summary written by Brifing from the original reporting.
