Bitcoin News Today: Nvidia's Earnings Ignite AI Optimism, Skeptics Warn of Tech Bubble

Nvidia's record-breaking third-quarter earnings report, released Nov. 19, 2025, briefly reignited optimism in the AI and crypto markets, sending Bitcoin surging above $92,000 amid broader tech-sector gains. The semiconductor giant reported $57.01 billion in revenue-62% higher year-over-year-exceeding Wall Street's $54.7 billion estimate and signaling sustained demand for its AI chips. CEO Jensen Huang highlighted "overwhelming" demand, with Blackwell GPU sales described as "off the charts" and cloud GPU inventory sold out. The results temporarily eased concerns about an AI sector slowdown, lifting shares of crypto miners and tech stocks in after-hours trading.

The earnings surge underscored Nvidia's pivotal role in the AI boom, with analysts noting its performance now heavily influences broader market sentiment. Cantor Fitzgerald, which maintains an Overweight rating on Nvidia, called the report "THE event of earnings season" and reiterated a $300 price target, citing the company's 71.55% year-over-12-month revenue growth. Meanwhile, the firm's bullish stance contrasts with growing skepticism about AI valuations. Investors such as Michael Burry and Peter Thiel have exited Nvidia positions, raising concerns about a potential bubble.

Bitcoin's brief rebound followed a volatile week marked by record ETF outflows, including a $523 million single-day redemption from BlackRock's IBIT. The crypto market's alignment with tech stocks intensified after Nvidia's results, with Bitcoin's 92% correlation to the Nasdaq underscoring its transformation into a "high-beta tech stock" rather than "digital gold," according to analyst Jesse Colombo. The rally also benefited bitcoin miners, with Cipher Mining and IREN surging over 10% post-earnings as optimism about AI infrastructure spending boosted risk appetite.

However, analysts caution that the relief is temporary. The crypto sector remains under pressure from macroeconomic headwinds, including softening rate-cut expectations and liquidity constraints. Bitcoin's recent "death cross" technical signal-a bearish indicator-persists, with the asset trading below key moving averages and facing institutional outflows. While Nvidia's guidance for $65 billion in Q4 revenue-above the $61.98 billion consensus-reinforces confidence in the AI cycle, market watchers emphasize that demand must broaden beyond hyperscale cloud providers to sustain growth according to analysts.

Nvidia's earnings also highlighted structural shifts in the tech industry. The company's extended GPU lifespans and three-generation product roadmap (Blackwell GB200, Blackwell Ultra GB300, and Vera Rubin) position it to dominate AI infrastructure through 2026. Yet competition is intensifying, with OpenAI and Google expanding their chip supplier lists, and margin pressures looming as AI infrastructure costs rise.

As the market digests Nvidia's results, attention turns to the Federal Reserve's policy trajectory and the health of the broader AI ecosystem. While Wednesday's report stabilized risk-on sentiment, underlying tensions-ranging from Trump-era Fed tensions to ETF redemption trends-suggest crypto and tech stocks remain vulnerable to volatility. For now, Nvidia's performance continues to serve as a bellwether, with its guidance offering a critical litmus test for the sector's long-term trajectory.
