Eligibility matrix

Six ETFs. Six different inclusion timelines.

QQQ● Eligible

Nasdaq listing + market cap easily clears Nasdaq-100 threshold. Fast-track entry possible if market cap exceeds existing constituent (top 25% rule).

Timing: Next quarterly rebal or special inclusion ~3-5 days post-IPO if mega-cap
IPO● Eligible

Renaissance IPO ETF adds large US IPOs ~5 trading days after listing. Will likely enter as a top-3 holding given mega-cap size.

Timing: ~5 trading days post-IPO
VTI● Eligible

CRSP US Total Market includes all US-listed common stocks. Added at next quarterly rebalance (typ. ~30-90 day lag).

Timing: Next quarterly rebalance
SPY● Excluded

Multi-class structure historically blocks/delays inclusion (Snap precedent in 2017); Profitability requirement (4 consecutive profitable GAAP quarters) likely not met; Public float below 10% threshold

Timing: Blocked until criteria met
VGT● Excluded

GICS Aerospace & Defense (Industrials sector). Excluded from VGT despite AI compute exposure.

Timing: N/A
ARKK● Conditional

Active fund — Cathie Wood's stated convictions strongly favor frontier-AI and space themes. Position size at PM discretion.

Timing: Any time post-listing
The playbook

Three trades the inclusion math points to.

i.

The largest IPO in history — by far

At $1.75T, SPCX dwarfs Saudi Aramco's record. QQQ ($327B AUM) and QQQM ($94B) become forced buyers — even at a tiny ~4% float, the entry weight in Nasdaq-100 is unprecedented. The IPO ETF (Renaissance) will cap-weight at 10% but SPCX likely dominates inclusion. First-day pop risk works against the inclusion trade — wait for the IPO ETF rebalance window.

ii.

The 4.3% float bottleneck

$75B raise / $1.75T valuation = ~4.3% public float. That fails S&P 500's 10% float minimum mechanically, blocking SPY/IVV/VOO inclusion at the first review. ETFs forced to buy must absorb their pro-rata share from an artificially restricted supply. Watch borrow rates spike in the first month — short interest will be extreme.

iii.

Space sector instant rerating

SPCX immediately becomes the comparable for every space-adjacent ticker: RKLB, ASTS, PL, IRDM, EchoStar, Globalstar. ITA (US Aerospace & Defense ETF) and UFO (Procure Space ETF) face forced rebalancing. The sympathy bid on these names typically peaks 2-3 days post-pricing then fades — that's the trade.
