Can China's Stock Market Rout Pull Bitcoin Lower?

China's artificial-intelligence stock bubble continues to deflate. The STAR50 index dropped 4.81% on October 27, carrying a slide of roughly 40% since July that has wiped out about $480 billion.

Bitcoin, meanwhile, continues to hold around $80,400, and whether the selloff spreads to digital assets may come down to two scenarios.

Scenario One: How Global Contagion Could Reach Bitcoin

The more immediate risk may be a spillover effect on Wall Street rather than a direct crypto selloff out of China. Should upcoming US technology earnings reveal that heavy AI infrastructure spending is still running ahead of realized revenue, worries about overvaluation could ripple outward.

The gauge finished at 1,252.28, while the CSI 300 fell roughly 4.81% over the past 24 hours. Technology shares, according to market data, spearheaded the late-session decline.

Nonetheless, China prohibits crypto trading and has in the past pushed mining operations offshore, leaving no direct route from Chinese selling into bitcoin.

The real dangers, however, lie elsewhere:

• US tech results could reveal that AI outlays are still exceeding revenue.
• Spot bitcoin ETFs have linked BTC more tightly to tech shares.
• Fund managers tend to sell liquid holdings during steep stock-market declines.

Prediction markets, too, indicate elevated odds of further strain on Western chip and AI equities.

Scenario Two: Could Funds Rotate Back Into Bitcoin?

Ki Young Ju, chief executive of CryptoQuant, argued recently that an AI collapse would barely touch bitcoin. In his view, bitcoin largely sat out the AI rally.

Scott Melker, in the meantime, flagged remarks from ARK's Brett Winton.

Winton described AI computing as a “black hole” for capital, a dynamic that raises the opportunity cost of holding bitcoin.

The bull case rests on three factors:

• Investors who sold bitcoin to chase AI shares could come back.
• Bitcoin is not reliant on chip supply chains or state subsidies.
• Once the initial risk-off selling fades, rotation may underpin prices.

Ju stressed, however, that an AI crash is not automatically positive or negative for bitcoin.

I don't think an AI bubble burst would hurt BTC much.

Bitcoin missed the entire AI rally. Those who bought AI stocks may have already sold their BTC. Now it may be time to rotate back into Bitcoin.

AI crash isn't necessarily bullish or bearish for BTC. They seem unrelated.

Where Analysts See Bitcoin's Price Heading Next

Traders are keeping an eye on key levels in the near term. Ted Pillows observed that Binance continues to buy and said bitcoin needs a daily close above $81,000 to restore momentum.

Michaël van de Poppe, meanwhile, pointed to a crowded week of macro events and earnings. A strengthening bearish consensus, he noted, often shows up near a local bottom, so an upside surprise is still possible.

There are many macroeconomic events that will move markets this week.

However, the consensus seems to be that we must fall down with #Bitcoin and other markets.

The consensus is even getting stronger.

Ultimately, bitcoin's direction may hinge less on China and more on whether the US AI spending narrative holds up. For now, markets are waiting on earnings and signals from the Fed.
