Weighting Increase

SpaceX's weighting in the Nasdaq 100 is expected to rise to about 2.82% from roughly 1.28%, based on pro forma data from Nasdaq's Global Index Watch circulated late Friday. The final weighting will be determined later this month. SpaceX's relatively small weighting dates to its addition to the gauge in July. Most of its shares were still locked up and unavailable for public trading, limiting the weighting it received even after Nasdaq changed its rules to allow newly listed large-cap companies to enter sooner and eliminated a requirement that at least 10% of their shares be publicly tradable.

Lockup Expirations

As those lockups expire, more SpaceX shares are becoming available for trading. That increases the company's free float, which can, in turn, increase its weighting in the Nasdaq 100. Additional SpaceX shares are scheduled to come out of lockup, potentially lifting its index weighting again. SpaceX's first lockup expiration came in August, alongside its first earnings release as a public company, prompting concern that a surge in newly tradable shares could overwhelm demand. The selloff didn't materialize, including after a second lockup expired a week later.

Market Impact

Wall Street expects the change to result in billions in new buying by index funds and exchange-traded funds that track the benchmark. They include the $481 billion Invesco QQQ Trust Series 1, known as QQQ. Roughly $1.7 trillion in assets tracked the Nasdaq 100 as of the end of the second quarter, according to Nasdaq. The Nasdaq 100 tracks the largest non-financial companies listed on the Nasdaq Stock Market. There is no minimum market capitalization for inclusion, though companies must have average daily trading volume of at least 200,000 shares and meet other requirements.
