- Nasdaq put forward a “Fast Entry” rule aiming to bring the largest new listings onto the Nasdaq-100 in just 15 trading days.
- To qualify, the newcomer must have a market value placing it within the top 40 of the current index members.
- This move arrives amid a growing pipeline of mega IPOs, ramping up the strain on index providers and the passive funds that follow them.
Nasdaq has put forward a “Fast Entry” rule aimed at letting certain new heavyweights join the Nasdaq-100 in just 15 trading days, cutting down the current wait that stretches for months.
Timing is crucial. A surge of major IPOs, like Elon Musk’s SpaceX and AI firm Anthropic, is gearing up for 2026. Funds tied to indexes might have to hold back or shell out more once these new entrants join the lineup.
Advisers for SpaceX, which Reuters recently reported acquired xAI, have reached out to major index providers about the possibility of an accelerated inclusion in key indexes, a source close to the matter told Reuters. SpaceX didn’t immediately respond to requests for comment, and Nasdaq declined to comment. Reuters
The proposal allows a newly Nasdaq-listed company, ranked in the top 40 by market cap among current Nasdaq-100 members, to join after at least five trading days’ notice and 15 sessions delay. Nasdaq clarified the company wouldn’t replace an existing member right away, temporarily increasing the number of constituents until the next annual reconstitution — the yearly index reshuffle.
“Faster inclusion makes Nasdaq a more complete ecosystem,” said Michael Ashley Schulman, partner and chief investment officer at Running Point Capital Advisors. He highlighted tighter spreads and improved liquidity driven by growing passive ownership.
The shift comes as index providers adapt to companies staying private longer, pushing massive market value into the spotlight at IPO. Bloomberg reported that SpaceX might target a valuation near $1.3 trillion in a possible IPO, potentially making it one of the Nasdaq-100’s largest members. The Nasdaq-100 underpins more than $600 billion in ETFs, with Invesco’s $410 billion QQQ as its biggest fund, according to the report. Theedgesingapore
“The proposed change would make the index more representative of the market in a timely way,” said Kaasha Saini, Jefferies’ head of index strategy. She also warned that passive funds risk missing early moves and then dealing with higher turnover when they eventually add positions.
Nasdaq’s consultation paper links the Fast Entry cutoff to overall size: by Dec. 31, 2025, ranking in the top 40 means having a market cap above roughly $100 billion. The exchange plans to apply any changes after the March 2026 quarterly rebalance, effective March 23. Comments are open until Feb. 27. Nasdaqomx
Nasdaq is looking to adjust weights for low-float stocks, where insiders hold most shares and daily trading is minimal. The proposal would multiply a company’s free float—the shares open to trading—by five, then cap that figure at 100%. This change would eliminate the existing 10% minimum float requirement.
Parameter.io announced that the package aims to maintain index stability by opting for temporary expansion instead of displacing current members. The proposal also reduces the waiting period for the largest newcomers to just 15 trading days. Nasdaq plans to implement the revised approach following its next quarterly rebalance. Parameter
The proposal remains under consultation, and rushing entry might drive up costs for index-tracking funds. They’d have to buy shares in a newly listed stock when trading is often thin and volatile. If a mega IPO falters early on, passive funds could end up forced to buy into a sinking stock.
Thursday’s early session saw the Nasdaq Composite slide roughly 1.4%, MarketScreener data showed. Marketscreener
