Here's how SpaceX's Nasdaq-100 inclusion might affect options pricing

SpaceX bulls are proving a devout lot, not unlike the Tesla traders that came before them. Daily options flows still lean heavily bullish almost a month into trading and one day ahead of the stock's accelerated inclusion into the Nasdaq 100, the index behind the roughly $500-billion Invesco QQQ fund , of which Elon Musk's new giant will garner a roughly 1% weighting. About half-a-million SpaceX options traded by midday Monday, a little below the average since inception, but still enough to be the fifth-most popular stock for options trading. More than 300,000 calls traded, compared to less than 130,000 puts, with almost five times as many calls bought versus puts, according to ThinkOrSwim data. Tesla, Musk's other trillion-dollar company, is consistently among the most active stocks for options traders. Nasdaq's inclusion of SpaceX will in theory make the tech-heavy index marginally more volatile overnight given SpaceX's wild swings, but the Nasdaq's rules limit the weight of low float stocks, so the impact will likely be minimal. How SpaceX releases shares around its lockup timeline, how passive index buyers handle its inclusion, and overall demand for options, will determine if SpaceX stays as wild as it did when it came out to market.
