SpaceX and OpenAI: The Mega IPO Grift
Ben Felix
0:00 Some massive companies are set to go
0:01 public very soon.
0:02 Private companies like SpaceX, OpenAI and Anthropic would rank
0:06 among the largest companies if they went
0:08 public and index funds would be forced
0:10 to buy their stock.
0:12 That means that if
0:12 you are an index fund investor, you may
0:14 soon be investing in these companies
0:16 whether you like it or not.
0:18 The problem is that most IPOs are terrible
0:20 investments and these ones in particular
0:23 raise some questions.
0:24 I'm Ben Felix, chief investment officer at PWL Capital,
0:27 and I'm going to tell you what the
0:28 upcoming mega IPOs mean for you and your
0:31 portfolio.
0:36 In this video, I'm going to take you
0:37 through how stock indices and the index
0:40 funds tracking them include IPOs, how
0:42 this might affect index fund returns,
0:44 and what you can do about it.
0:46 I'll also cover whether index fund investors are
0:48 missing out on private market returns,
0:50 which is a common perception based on
0:53 companies staying private longer.
0:55 Index funds are generally great investments
0:57 because they roughly deliver the returns
0:59 that the public stock market has to
1:00 offer.
1:01 Since their primary role is
1:03 representing the stock market, some
1:05 stock indices aim to include new IPOs
1:08 soon after the company goes public.
1:10 This makes sense for the purpose of
1:12 representing the public stock market.
1:14 But the problem for index fund investors
1:16 is that IPOs have had historically
1:19 terrible returns.
1:20 I'll come back to that
1:20 point later.
1:21 Index funds today control
1:23 trillions of dollars.
1:24 So, if you're a
1:25 new company listing on the stock market
1:27 or an investment bank facilitating an
1:29 IPO, getting the stock included in a
1:32 major index or multiple indices can mean
1:34 huge investment dollars flowing into its
1:37 shares on the public market as index
1:39 funds are forced to buy, giving sellers
1:41 liquidity and pushing up the share
1:43 price.
1:44 This makes index inclusion very
1:47 desirable for shareholders of the newly
1:49 listed company, but probably not so much
1:51 for the index fund investors who are
1:53 left holding the bag.
1:55 And it is often a
1:56 bag that they are left holding.
1:58 Companies tend to go public when they
1:59 think they can sell their stock at a
2:01 high price.
2:02 Meaning, the moment you can
2:03 buy their stock on the secondary market
2:05 is precisely when the insiders believe
2:07 it's overvalued or at least nicely
2:10 valued.
2:10 If you're an investor, you
2:12 probably don't want to buy an overpriced
2:14 stock, but index funds don't have that
2:16 kind of discretion.
2:17 They're forced to gobble up whatever is included in the
2:20 index, regardless of its price.
2:22 The IPO inclusion rules vary across indices.
2:24 For example, as of right now, the S&P 500
2:27 requires a stock to have been trading on
2:29 a public exchange for 12 months before
2:32 inclusion, while the S&P total market
2:34 index allows for inclusion within 5 days
2:36 for stocks that meet certain criteria.
2:38 This is called fasttrack entry which is
2:40 important to understand.
2:41 Basically stocks that meet certain criteria can be
2:45 eligible for near immediate inclusion in
2:47 some total market indices.
2:49 As I mentioned, the S&P 500 has historically
2:52 required shares to trade for a year
2:54 before inclusion.
2:55 But as reported by
2:56 Bloomberg, S&P may be considering an S&P
2:58 500 rule change to accelerate the
3:01 inclusion of mega IPOs like SpaceX.
3:04 NASDAQ is considering similar changes
3:06 for the NASDAQ 100 to accelerate
3:08 inclusion.
3:08 The implications here for
3:10 index fund investors are important.
3:12 A 2025 paper looks at how fast track entry
3:15 into Crisp, that Center for Research and
3:17 Security Prices Indices affects stock
3:20 returns and IPO deal structure.
3:22 VTI, for example, a large ETF, tracks the CRISP
3:26 US total market index.
3:27 Crisp adds eligible securities to the index within
3:30 as few as 5 days for fasttrack entry.
3:33 The authors of this paper show that
3:35 expected index investor demand for IPO
3:37 shares causes FastTrack IPOs to
3:40 outperform their non-fastrack counterparts by over 5 percentage points
3:44 following their listing.
3:45 This outperformance peaks at the index
3:47 inclusion date and reverts significantly
3:49 within two weeks thereafter.
3:51 Basically, index funds are being frontr run by
3:53 intermediaries like hedge funds who know
3:56 that index funds are going to be buying
3:58 the shares once they become eligible for
4:00 index inclusion and then the index funds
4:02 end up holding the shares as they revert
4:04 back down closer to their IPO price.
4:07 The authors call this a shadow tax largely
4:09 paid by index fund investors.
4:11 It's like ticket scalpers for concerts and sports
4:13 events.
4:14 Another important index definition that's proving to be relevant
4:16 to mega IPOs is the concept of free
4:19 float.
4:19 Free float is the proportion of a
4:21 company's shares that are available for
4:22 purchase in the public equity market.
4:24 Most major indices have a minimum float
4:26 requirement and weight stocks by their
4:29 public float.
4:30 A company could go public
4:31 while only making a small portion of
4:33 their overall market capitalization
4:34 freely available on the public exchange.
4:36 This would be referred to as a lowflat
4:39 IPO.
4:40 As reported by the Financial Times,
4:42 SpaceX plans to float less than 5% of
4:44 its equity, much lower than the average
4:46 IPO.
4:47 With a$ 1.75 trillion valuation,
4:50 but only a 5% public float, most indices
4:53 would weight it at its float of 88
4:55 billion, and many would actually exclude
4:57 it altogether.
4:58 NASDAQ currently has a
4:59 10% minimum float and weight stocks
5:01 based on the value of all listed shares
5:03 of the company with no regard for free
5:05 free float, which is unique.
5:07 But they recently approved rule changes following
5:09 a public consultation to speed up IPO
5:11 inclusion, eliminate the lowflat cutoff,
5:13 and introduce a float factor in their
5:16 waiting of lowflat stocks.
5:17 The cynical view on this is that NASDAQ is changing
5:21 the NASDAQ 100 index rules to win SpaceX
5:24 over in an effort to get their listing
5:26 on the NASDAQ exchange.
5:28 including in the index would force significant index fund
5:31 buying, which likely ends up being good
5:33 for SpaceX, its early investors, and
5:36 NASDAQ, but potentially comes at the
5:38 expense of NASDAQ 100 index fund
5:41 investors.
5:42 Some indices like the crisp
5:43 US total market index tracked by VTI
5:46 continue to have a low float cutoff of
5:48 10% for fasttrack entry into the index.
5:51 Between inclusion criteria and index
5:53 waiting methodologies, there's some
5:55 uncertainty about how these mega IPOs
5:57 will initially show up in indices.
5:59 But there's no question that their listings
6:01 will change the public market over time.
6:03 That's likely why index providers are
6:05 considering making changes to get these
6:07 companies represented in their indices.
6:09 To reiterate a point from earlier,
6:11 indices are meant to represent the stock
6:13 market.
6:13 A blog post from index provider
6:15 S&P Global shows that just SpaceX,
6:17 OpenAI, and Anthropic would make up 2.9%
6:20 of the S&P World Index at their full
6:23 market caps.
6:24 That's almost as much as
6:25 Canada.
6:26 But these numbers assume that
6:27 the total market cap of the companies is
6:29 included in the index.
6:30 Since many of these IPOs are expected to have low
6:32 public floats, that should be accounted
6:34 for in estimating their market impact.
6:36 In another blog post, index provider
6:38 MSCI calculated the potential changes to
6:40 the MSCI allcountry world investable
6:43 market index in the event of some of the
6:45 largest private companies going public
6:47 in 2026.
6:48 This was written back in
6:50 February 2026 when SpaceX had a quaint
6:53 valuation of only 800 billion, but the
6:56 general points are still relevant.
6:58 They ask in the blog post what would happen
6:59 to the index to this world index if the
7:02 10 largest companies from the Msei all
7:05 country venturebacked private company
7:07 index went public.
7:09 Since the free float
7:10 at the time of listing is unknown, they
7:12 go through a few scenarios.
7:13 At a 5% float, only four of the 10 large private
7:16 companies would achieve index inclusion
7:18 based on MSCI's inclusion rules.
7:20 At a 10% float, seven of the 10 companies
7:23 would achieve index inclusion, but not
7:25 at enormous weights in the index.
7:27 While the overall market weight changes in
7:29 percentage terms would not be huge, even
7:31 at a 25% float scenario, MSEI finds that
7:34 the dollar flows just for funds tracking
7:36 MSCI indices would be huge with newly
7:39 listed private companies receiving
7:41 billions in investor dollars and the
7:43 largest existing public companies seeing
7:45 billions in outflows.
7:47 These flows are what ultimately matter to index fund
7:49 investors who are being forced to buy
7:51 shares.
7:52 Okay, so index funds, depending
7:54 on the rules of the specific indices
7:56 they track, may or may not invest in
7:58 these mega IPOs.
7:59 And even if they do, it
8:00 will likely be at a weight reflecting
8:02 their public float, except for the
8:04 NASDAQ 100, which as of recently would
8:06 use its newly adopted float factor.
8:09 An important piece of understanding this
8:10 whole situation is the empirical fact
8:12 that investing in IPOs is one of the
8:15 worst investment strategies that exists.
8:17 Before I get to that though, make sure
8:19 to subscribe if you haven't already.
8:20 I make nerdy research-driven videos to
8:22 help you make more informed financial
8:24 decisions.
8:24 Okay, IPOs tend to have a
8:26 first day pop where the price on the
8:29 public market jumps up relative to the
8:31 IPO price, but most investors don't get
8:33 the IPO price.
8:34 Investing in the shares
8:35 once they are listed on the public
8:37 market, so after the pop has been rough
8:40 to say the least.
8:41 The consistent pattern of IPO underperformance even has a name.
8:44 It's the new issues puzzle coined in a
8:46 highly cited 1995 paper which found that
8:49 companies issuing stock from 1970 to
8:51 1990 tended to be poor investments.
8:54 The paper finds that investors in IPOs
8:56 receive average returns of only 5% per
8:58 year while similar listed firms returned
9:01 12% over the same period.
9:03 The paper notes that to achieve the same wealth 5
9:05 years later, an investor would have had
9:07 to put 44% more money into the new
9:10 issues in the sample than into
9:12 established firms of the same size.
9:14 A more recent 2019 study from Dimensional
9:16 Fund Advisors looked at the first year
9:18 secondary market performance of more
9:20 than 6,000 IPOs from 1991 to 2018 and
9:24 found that a portfolio of IPOs generally
9:26 underperformed the market and a small
9:27 cap index by about 2% per year.
9:30 The main exception to this finding was in the
9:32 1992 to 2000 period when the IPO
9:34 portfolio outperformed the small gap
9:36 index by about 1.1% annually mainly due
9:39 to IPOs consisting of small tech
9:42 companies that took off in the dotcom
9:44 boom and uh I mean we all know what
9:47 happened after that.
9:48 The study found that these poor returns were largely
9:50 explained by the factors in the FM and
9:52 French five factor asset pricing model.
9:54 The IPO portfolio behaves like a
9:56 portfolio of small growth,
9:58 lowprofitability, high investment stocks, also known as junk or small crap
10:02 growth.
10:03 These types of stocks are more
10:05 volatile and tend to lag behind the
10:06 broader market.
10:07 We don't even need these
10:08 papers though.
10:08 These findings are easy
10:09 for anyone to replicate and update today
10:12 because of course there is an ETF for
10:14 IPOs.
10:15 The Renaissance IPO ETF
10:17 exclusively invests in large US IPOs
10:20 when they list and then sells the shares
10:23 after they've been public for three
10:24 years.
10:25 It has underperformed VTI which
10:27 tracks the total US market by more than
10:30 six percentage points annualized since
10:32 inception in October 2013.
10:34 And as expected, it behaves like a portfolio of
10:38 small stocks with high prices, low
10:40 profitability, and aggressive asset
10:42 growth.
10:43 Similar results can be found
10:44 internationally since 2014 with the
10:47 Renaissance International IPO ETF IPOS.
10:51 Yes, that is the real ticker.
10:53 Professor Jay Ritterder, co-author of the new
10:55 issues puzzle, maintains an up-to-date
10:57 database of IPO returns.
10:58 In that data spanning 1980 through 2023, the average
11:03 three-year buy and hold return for IPOs
11:05 purchased on the secondary market trails
11:08 the market by 19 percentage points.
11:10 Lowflat IPOs look particularly bad.
11:13 Remember, a lowflat IPO means that only
11:15 a small portion of the company's shares
11:17 are available for public trading, which
11:19 can amplify price swings because demand
11:21 is concentrated on a limited supply.
11:24 This is widely expected to be the
11:25 approach for companies like OpenAI and
11:28 SpaceX.
11:28 Lowflat IPOs for high revenue
11:31 companies are rare, but they're not
11:33 totally unheard of.
11:34 I reached out to
11:34 Professor Ritterder, a past guest on my
11:36 podcast, to see if he had any data on
11:39 large lowflat IPOs specifically.
11:42 He sent me this table, which you nerds are
11:44 getting an exclusive look at.
11:46 He found 11 lowflat, that is below 5% float IPOs
11:50 for companies with inflationadjusted
11:52 trailing 12-month sales of $100 million
11:56 or more going back to 1980.
11:58 10 of the 11
11:59 IPOs underperformed the market within
12:01 three years with average
12:03 underperformance of roughly 50% from the
12:05 offer price and over 60% from the first
12:08 day close suggesting that constrained to
12:11 supply may drive early price spikes but
12:14 tends to be followed by significant
12:16 underperformance.
12:17 He also mentioned that
12:18 these examples tended to have high price
12:20 to sales ratios at the time of IPO which
12:23 is very relevant for the current
12:25 potential mega IPOs.
12:27 If SpaceX were to
12:28 achieve a$ 1.75 trillion valuation, it
12:32 would have a price to sales ratio of
12:33 more than 100 times based on trailing
12:36 sales.
12:36 For context, the highest price to
12:39 sales ratio for an S&P 500 constituent
12:41 today is Palanteer's 73 times, while the
12:45 index as a whole trades at a price to
12:46 sales of 3.1 times.
12:49 In general, high valuations are associated with low
12:52 expected future returns.
12:53 For index fund investors, this problem is complicated.
12:56 When large private companies go public
12:58 with high valuations, they change the
13:00 landscape of the broader market.
13:02 In response, indices must rebalance to
13:05 remain reflective of the broader market.
13:07 Market cap weighted indices must
13:09 rebalance in response to stock market
13:11 composition changes, which in some cases
13:13 can include IPOs.
13:14 In doing so, index
13:16 funds implicitly engage in market
13:18 timing.
13:19 The problem is that it tends to
13:20 be really bad market timing.
13:23 Issuers, that's like companies listing on the
13:25 public market, will generally want to
13:27 issue stock when their valuation is
13:29 high, when when they believe their
13:31 valuation is high and buy it back when
13:33 their valuation is low.
13:35 Index funds in their effort to track the indices that
13:38 reflect the market end up buying high
13:41 and selling low.
13:42 The 2025 paper index
13:44 rebalancing and stock market
13:45 composition, do indexes time the market?
13:48 estimates that this timing ends up
13:50 creating a performance drag of between
13:52 47 and 70 basis points per year relative
13:55 to a delayed rebalancing approach.
13:58 In other words, there is a lasting negative
14:00 effect on your portfolio that could have
14:02 been avoided had your index fund
14:03 prioritized expected returns rather than
14:06 tracking error to its index.
14:08 Listen, I'm a huge fan of index funds, but this
14:12 issue right here is one of the reasons
14:13 that I don't use them personally or for
14:15 the clients of PWL Capital.
14:17 I use funds from Dimensional Fund Advisors, which
14:20 are a lot like index funds, but don't
14:21 track an index, and intentionally avoid
14:24 investing in IPOs for about a year after
14:26 the company lists.
14:27 They also intentionally tilt away from the junk
14:30 that IPOs tend to behave like more
14:32 generally.
14:32 To be clear, my firm PW
14:34 Capital does use Dimensional Funds, but
14:36 I was not paid by Dimensional or anyone
14:38 else to say this, and I gain nothing
14:41 from you using their products.
14:43 With companies staying private longer and
14:45 going public when they're larger, the
14:47 next question that is natural to ask is
14:49 whether investors should be seeking
14:50 exposure to private company shares
14:52 before they go public.
14:54 There are a couple of things to think about here.
14:56 There's a huge amount of survivorship
14:58 bias in private company outcomes.
15:00 For every SpaceX or Open Eye that we hear
15:02 about, there are thousands of companies
15:04 that did not grow or failed entirely.
15:07 This skewess exists in public markets
15:09 too, but it's even more brutal, even
15:11 more pronounced in private markets.
15:13 Additionally, the fees and costs
15:14 associated with private company
15:16 investments can often absorb the
15:17 financial benefits of owning them.
15:19 This has been true with private equity funds
15:21 in general, which have delivered net of
15:23 fee returns in line with public markets.
15:25 There are some wild stories floating
15:27 around right now about the lengths
15:28 people have gone to to buy what they
15:30 hope is exposure to companies like
15:32 SpaceX.
15:33 One specialurpose vehicle reported on by Wall Street Journal had a
15:37 4% upfront fee with an additional fee of
15:40 25% of future profits.
15:42 There are also questions about who owns what due to the
15:44 complicated structures.
15:45 And of course, there are stories of outright fraud.
15:48 I think people imagine all the money they
15:50 will make if they can buy some SpaceX
15:52 shares at a low valuation and then sell
15:54 when it goes public.
15:56 But unless you're an employee or otherwise have direct
15:58 access to the company's shares,
16:00 financial intermediaries that do have
16:02 access are not typically going to give
16:04 you access to the equity on terms that
16:07 are better for you than they are for the
16:09 intermediary.
16:10 Financial intermediaries don't tend to be in the business of
16:13 giving you money for free.
16:15 Some ETFs have gotten exposure to SpaceX shares
16:17 either directly or through specialurpose
16:19 vehicles.
16:20 One example that has attracted
16:21 a lot of attention is the ERS shares
16:23 private public crossover ETF.
16:26 It bought into SpaceX through an SPV in December
16:28 2024.
16:29 SPVS are not particularly liquid.
16:31 So, this ETF has had to deal with some
16:33 unique practical issues as a liquid ETF
16:36 holding a large stake in an illlquid
16:38 asset.
16:39 But even more interesting to me
16:40 at least is that despite SpaceX
16:43 reportedly rising in value substantially
16:45 since this ETF invested in it back in
16:47 December 2024, the fund has lost money
16:50 in absolute terms and even more so
16:52 relative to the market.
16:54 There are multiple reasons for this and it gets
16:55 complicated quickly and that's part of
16:57 the problem.
16:58 As Jeff Tac, managing
16:59 director for Morning Star Research
17:00 Services, widely noted in his analysis
17:03 of XOVR, when it comes to investing, the
17:06 more you covet something, the more you
17:07 should probably question your desire to
17:09 own it in the first place.
17:11 Investors are so eager to get a piece of SpaceX that,
17:14 at least in this case, they got burned.
17:16 Some good news is that while it's
17:17 generally difficult to get access to the
17:19 private company shares that you really
17:20 want, a lot of public companies make
17:23 strategic investments into private
17:24 companies.
17:25 Public market investors are
17:26 not entirely locked out of private
17:28 markets.
17:29 Okay.
17:29 What does all this mean
17:30 for you, the index fund investor?
17:33 Yes, it's possible that these upcoming mega
17:36 IPOs will affect market indices and the
17:38 index funds tracking them, especially if
17:40 these companies are fasttracked for
17:42 index inclusion.
17:44 Due to index fund
17:45 mechanics, index funds will buy up IPO
17:48 shares that are included in the index at
17:50 any price, leading to adverse selection
17:53 and potentially even making the problem
17:55 worse for themselves as they bid the
17:57 price of the stocks up.
17:58 If you're an index fund investor already, this is a
18:01 cost you have been paying an implicit
18:04 cost.
18:04 Maybe these cases are a bit more
18:06 extreme, but this is part of the
18:07 indexing lifestyle.
18:09 You can either accept it and carry on or look at
18:11 alternatives like dimensional funds that
18:13 are similarly lowcost and broadly
18:15 diversified but don't auto invest in
18:17 IPOs.
18:18 No, you probably can't get access
18:19 to these private company shares prior to
18:21 their IPOs.
18:23 When everyone wants to buy
18:24 something, either its price or the cost
18:26 of accessing it will absorb a huge
18:28 portion of the benefit you think you're
18:30 going to get from investing in it.
