What happens when crypto trades stocks while Wall Street sleeps?

The appeal of after-hours trading is easy to understand. In the past six months, we've seen some of the most influential and consequential announcements and decisions happen after market close, ranging from offhand comments from the US President to Nvidia earnings.

You might have an opinion about what semiconductor stocks will do when trading resumes, and you'd rather back it immediately than wait until morning.

There's a complication, though. When you trade a stock or an index of stocks whose primary market is closed, you're trading an estimate of what those stocks are worth. That estimate isn't necessarily the price you'd get if you tried to buy or sell the underlying shares.

Usually, the difference is manageable, and most traders don't notice it. But sometimes, especially with leverage, it can become the entire trade.

The bets aren't closed

MarketVector has licensed its US semiconductor index, which is tracked by VanEck's SMH exchange-traded fund, to Paragon for a perpetual futures contract on Hyperliquid. The product uses an extended-hours index calculated with Pyth price data, letting traders speculate on semiconductor stocks outside the regular US trading session.

Paragon says it has launched 29 markets and handled nearly $500 million in trading volume since April 2026, though those figures don't show how much activity the semiconductor contract itself has attracted.
