Retail options traders piled into bullish bets, lifting options volume in Robinhood Markets, Tesla, Palantir Technologies and SpaceX and signalling aggressive risk appetite as September opened. Activity was concentrated in a handful of high-volatility, retail-favourite names, where calls outnumbered puts by at least two-to-one and overall flows leaned decisively bullish.
Robinhood stood out as the most overtly bullish name on Thursday. Calls traded more than twice as often as puts, and buyers took nearly three times as many calls as puts, while put selling exceeded put buying. Volume ran at more than triple the stock's average daily level. The underlying stock turned positive year to date after Thursday's large gain and moved within striking distance of a fresh year-to-date high.
Palantir also attracted heavy options interest, ranking inside the top 10 most traded single-stock options and trading at roughly double its typical daily volume. Traders bought about twice as many calls as puts in the software name, and more puts were sold than bought, a pattern consistent with directional bullish positioning.
Musk-linked names were central to the surge. Both Tesla and SpaceX ranked near the top of single-stock options volume, and traders bought roughly twice as many calls as puts in each, with significant put selling on both names. SpaceX reclaimed the $150 price level, a mark it had not closed above since early July, even as its 30-day implied volatility sits in the 4th percentile and at about half its historical average since the company went public June 12.
Broader volatility metrics reinforced the backdrop for this activity. The Cboe Volatility Index, or VIX, traded below 15, reflecting a notable decline in implied volatility across the S&P 500 and individual stocks. That drop makes call buying and put selling comparatively cheaper, encouraging directional bets ahead of company-specific catalysts.
Event risk is already shaping the flows: the week includes a Tesla Cybercab event in Austin, Texas, which may be amplifying bullish positioning in Musk-related equities. Traders appear to be exploiting low volatility to lever bets into names that move sharply on news, a dynamic that could intensify if volatility stays compressed or if any of the anticipated events deliver a market surprise.
