While the US stock market was closed, cryptocurrency perpetual contracts were already pricing in the US stock market. Regarding the Nvidia situation, I initially just wanted to see how much it dropped over the weekend. Later, after calculating the trading volume on Binance and the US stock spot market together, I realized I had underestimated the size of this market. On November 9th, during the 6.5 hours of regular trading on the US stock market, approximately 460 million Nvidia shares were traded in the spot market, roughly equivalent to over $82 billion based on the closing price. During the same 6.5 hours, a single Nvidia perpetual contract on Binance traded 885 million USDT, roughly equivalent to 1.1% of the spot trading volume. By the full day (UTC), Nvidia perpetual contracts traded 1.667 billion USDT, four times the daily average of the previous five trading days, and nearly half of the trading occurred outside of regular US stock trading hours. Micron also traded 1.092 billion USDT that day. Including Google, Intel, and AMD, five US stock perpetual contracts saw a trading volume of 3.515 billion USDT in a single day. This figure was unexpected before I checked. Looking further back, there was a cross-platform 24-hour snapshot before the US stock market opened on Monday. Binance's Nvidia perpetual contracts traded $360 million, accounting for 44% of the trading volume across the eight platforms surveyed, nearly double that of the second-ranked platform. Its open interest was $90.57 million, also the highest. In terms of price, Nvidia closed at $186.64 on Friday. Around 7 PM EST on Sunday, more than 14 hours before the Nasdaq opening, Nvidia perpetual contracts on Binance had already reached $178.21, 4.5% lower than Friday's close. The spot market opened at $173.07 on Monday, a 7.3% lower opening. From now on, I'll pay more attention to perpetual contract trading volumes when I encounter such weekend news. Where Nvidia will open on Monday is unknown on Sunday. But hundreds of millions of dollars worth of transactions have already been digesting this news before the spot market even opens.
