SpaceX closed at $133.11, rising 15.83%. Despite the sharp rally, a massive $19.07 million synthetic short position dominated the tape, overwhelmingly shaping a bearish big-money sentiment. This conviction clashed with a $17.43 million bullish put sale, creating a starkly divided, conflicting flow picture on a single day of elevated options activity.

Options Indicators

SPCX’s implied volatility stands at 90.55%, and with an IV percentile of 87.20%, current option pricing sits in an elevated regime where contracts are relatively expensive versus the stock’s own recent volatility history. The IV/HV ratio of 1.10 further suggests implied volatility is running modestly above realized volatility, indicating the market is building in a premium for forward uncertainty rather than pricing options cheaply. The Call/Put volume ratio is 1.42.

Large Trades

A synthetic short position worth $19.07 million was the largest featured trade, built by buying 6,030 contracts of the 140.0 put expiring September 18, 2026, and selling 6,030 contracts of the 140.0 call with the same expiration. This is a classic bearish directional strategy designed to replicate short stock exposure, typically used to express downside conviction or hedge against a decline. Based on the listed legs, the trader paid $11.95 million for the long puts and received $7.12 million from the short calls, resulting in a net premium of -$4.82 million, or a net debit. With SPCX referenced at $133.11, the 140.0 put was in the money while the 140.0 call was out of the money, reinforcing that the structure was positioned to benefit from weakness and carried a clearly bearish message.

A PUT sale worth $17.43 million was the other standout trade, involving the sale of 5,000 contracts of the 130.0 put expiring September 17, 2027. This was a bullish single-leg position, as short puts generally reflect willingness to buy the underlying at a lower effective level while collecting premium income upfront. Since SPCX was trading at $133.11, the 130.0 strike was out of the money at the time, indicating the seller was expressing constructive or at least moderately confident downside-tolerant positioning rather than immediate distress. Strategically, this kind of trade often signals a view that the stock or ETF will stay above the strike over time, with the trader seeking premium capture and potentially using the short put as an income-generating bullish entry framework.

Overall, large-trade sentiment in SPCX leaned bearish. Although there was meaningful bullish activity, including sizable put selling and some bullish spread structures, the dominant tone was shaped by heavier bearish premium concentrated in downside-oriented positions, especially synthetic short exposure and outright put buying. The character of the flow suggests investors were more focused on protecting against or positioning for weakness than on chasing upside, so the broader read from the full large-trade tape is cautiously to clearly negative.

Strategy Reference

For those seeking to follow the income-oriented bullish flow while managing risk, a seller could consider a further out-of-the-money put like the 110.0 strike expiring in 2027 to achieve a lower assignment probability, or alternatively employ a bull put spread to strictly define maximum loss and reduce margin requirements.
