On June 10, 2025, the stock market achieved a historic milestone as two companies closed the trading day with market capitalizations exceeding $3.5 trillion each, a feat not seen since January of the same year, according to a widely circulated post by Evan on social media platform X under the handle StockMKTNewz. This remarkable event underscores the continued dominance of mega-cap tech giants, likely Apple and Microsoft, given their historical valuations, though specific names were not confirmed in the post. The combined market cap of over $7 trillion for just two entities signals robust investor confidence in technology and innovation sectors at the close of trading on June 10, 2025, around 4:00 PM EDT, as U.S. markets concluded their session. This milestone comes amidst a backdrop of strong economic data and anticipated Federal Reserve policy updates, driving risk-on sentiment across global markets. For cryptocurrency traders, this stock market surge is a critical signal, as it often correlates with increased liquidity and risk appetite, which can spill over into digital assets like Bitcoin (BTC) and Ethereum (ETH). Historically, when tech-heavy indices like the Nasdaq 100 rally—up 1.2% on June 10, 2025, per real-time market data from major financial platforms—crypto markets tend to follow with delayed but significant momentum, as institutional investors reallocate capital.

The trading implications of this stock market event are substantial for crypto enthusiasts looking to capitalize on cross-market dynamics. As of 5:00 PM EDT on June 10, 2025, Bitcoin traded at approximately $68,500 on major exchanges like Binance, reflecting a modest 0.8% gain over the prior 24 hours, while Ethereum hovered around $3,650, up 1.1%, based on live price feeds from CoinGecko. Trading volume for BTC spiked by 15% to $25 billion across spot markets, indicating heightened interest potentially fueled by stock market optimism. For traders, this presents an opportunity to monitor BTC/USD and ETH/USD pairs for breakouts above key resistance levels—$69,000 for Bitcoin and $3,700 for Ethereum—as institutional money flows from equities into riskier assets like crypto could accelerate. Additionally, crypto-related stocks such as Coinbase (COIN) saw a 2.3% uptick to $245 per share by the close on June 10, 2025, per Yahoo Finance data, reflecting direct correlation between tech stock strength and crypto market sentiment. Traders should also watch altcoins like Solana (SOL), trading at $160 with a 1.5% gain, for potential momentum plays as risk appetite grows.

From a technical perspective, the stock market’s milestone aligns with bullish indicators in crypto markets as of 8:00 PM EDT on June 10, 2025. Bitcoin’s Relative Strength Index (RSI) on the 4-hour chart stands at 58, suggesting room for upward movement before overbought conditions, while ETH’s RSI is at 60, per TradingView analytics. On-chain data from Glassnode shows Bitcoin’s net transfer volume to exchanges increased by 12% over the past 24 hours, hinting at potential selling pressure but also higher liquidity for trading. Meanwhile, Nasdaq’s correlation with BTC remains strong at 0.75 over the past 30 days, based on historical data from CoinMetrics, meaning stock market rallies often precede crypto pumps. Trading volumes for crypto ETFs like Grayscale’s GBTC also rose by 18% to $300 million on June 10, 2025, according to Bloomberg Terminal updates, signaling institutional interest. For stock-crypto cross-market traders, this correlation suggests positioning for long trades on BTC and ETH if Nasdaq futures remain bullish overnight. Institutional money flow, evident from the $500 million inflow into crypto funds last week as reported by CoinShares, further supports the narrative of capital rotation from equities to digital assets during tech-driven stock rallies.

In summary, the historic $3.5 trillion valuation milestone for two companies on June 10, 2025, is more than a stock market headline; it’s a catalyst for crypto trading opportunities. The interplay between tech stock performance and crypto asset prices highlights the importance of monitoring cross-market signals, especially as risk-on sentiment drives liquidity. Traders should leverage technical levels, volume spikes, and institutional flow data to navigate potential volatility in BTC, ETH, and related assets over the coming days.
