Five Dates That Will Make or Break SpaceX Stock
By Mark Gardner, Investment Strategist, MPC Markets | 17 June 2026
SpaceX has five dates between now and June 2027 that will decide whether this stock doubles or halves. There is no middle ground here, not at these multiples.
SPCX listed at $135, ran past $200 inside a week, and every single analyst price target is already underwater. The free float is 4.3%. That is not a typo. Four point three percent of the company trades freely. And the calendar ahead is unusually readable for a stock this young, but it is also unusually dangerous.
What follows are the five events that will shape the next twelve months for SpaceX shareholders. Each one has a bull case and a bear case. Some of them overlap. Some of them compound. The order matters because each outcome changes how the market interprets what comes next.
BULL The forced buying here is staggering. Index funds tracking the Nasdaq-100 need to purchase somewhere between $7 billion and $14 billion of SPCX. And they are buying into a 4.3% free float. CME's float multiplier treats the effective float as roughly 12.9%, which means the squeeze dynamic is about three times more violent than the raw number suggests. This all happens in a market-on-close auction on a single day. The concentration is extreme.
BEAR This is a zero-sum game. Every dollar going into SPCX comes out of Apple, Nvidia, Microsoft, and the rest of the QQQ basket. Fund managers selling winners to buy a company trading at 100 times sales. The inclusion date has been known since listing day, front-running has already happened, the stock is up 30% in a week.
MARK'S LEAN The sell-the-news risk is real. Yes the mechanics are genuinely powerful, $7 billion into a thin float produces fireworks. But the stock already reflects a lot of that. If you bought at $135 you are sitting pretty. If you are buying at $200 specifically for QQQ inclusion, you are paying for an event that every quant desk on Wall Street has already modelled. I would be cautious here.
BULL The angle most people are missing here is competitive. Blue Origin's New Glenn literally exploded on the pad in May 2026. That was supposed to be the credible alternative for heavy-lift launch. It's gone. SpaceX already had near-monopoly pricing power in the commercial launch market, and a clean Flight 13 cements it. One confirmed commercial Starship delivery transforms the revenue story entirely. The addressable market goes from billions to tens of billions overnight.
BEAR The FAA is the gating item, not the engineering. Two consecutive booster losses would kick the revenue thesis down a quarter, maybe two. And at 100 times sales, duration matters enormously. Every quarter of delay compresses the present value of those future revenues. Flight 12's booster loss was not catastrophic but it was not clean either.
MARK'S LEAN Analyst models have not caught up to the New Glenn collapse yet. SpaceX's competitive position got meaningfully stronger in a way that takes months to show up in consensus price targets. The market is still pricing this as a launch company with a competitor. It is now a launch monopoly with regulatory risk. Those are different things.
The Five Events at a Glance
| # | Date | Event | What to Watch |
|---|---|---|---|
| 01 | Jul 6-7 | QQQ Inclusion | $7-14B forced buying into 4.3% float. CME multiplier amplifies squeeze 3x. Sell-the-news risk after 30% run-up. |
| 02 | c. Jul 3 | Starship Flight 13 | Blue Origin's New Glenn grounded after May explosion. Clean flight cements SpaceX heavy-lift monopoly. FAA is gating item. |
| 03 | Aug 2026 | Q2 Earnings + 20% Unlock | First public earnings. Starlink subscriber trajectory is key. Float doubles by late August, 6x IPO float by September. |
| 04 | Nov 2026 | Q3 Earnings + 28% Unlock | Largest single tranche. Palantir/Lyft precedent: 10-20% drawdown over 8 weeks. MSCI inclusion is potential offset. |
| 05 | Jun 13 2027 | Musk 366-Day Lockup | Largest potential single supply event. Markets price overhang weeks early. Signal vs. silence determines outcome. |
Want Our Take on SPCX?
We cover SpaceX and other high-conviction ideas in our investment recommendations. No fluff, just the trades we're actually watching.
See Our RecommendationsBULL This is the first earnings report as a public company. If the Starlink subscriber trajectory is clean, the entire narrative flips from "loss-making rocket business" to "profitable internet business that also does rockets." The $175.50 performance trigger for the accelerated unlock is already cleared at current prices. And a strong Q2 print gives institutions the cover they need to add to positions ahead of the bigger unlock later in the year.
BEAR The float practically doubles from late August and keeps expanding. Six times the IPO float by the end of September. These are 10-year private market holders who have been sitting on paper gains for a decade. They are selling. Some of them were early employees who have been waiting years for liquidity. If Q2 numbers also disappoint, losses widening from Q1's $4.28 billion, you get an earnings miss and a supply shock arriving together. That is a toxic combination at any valuation.
MARK'S LEAN The earnings themselves are almost secondary. What matters is the tone. Does management talk about a path to profitability, or do they talk about investing for growth? At 100x sales, the market needs to hear the word "profitable" soon. But the supply dynamic is the real story here. Watch the volume in the two weeks after the lockup starts lifting. That tells you everything about insider conviction.
BEAR I'm leading with the bear case here because this is the scariest event on the calendar. Twenty-eight percent of outstanding shares potentially entering the market in a single tranche. Look at what happened to Palantir after its first major lockup expiry: the stock dropped 20% over eight weeks. Lyft was similar. The base rate for loss-making companies after a major lockup expiry is a 10 to 20 percent drawdown over eight weeks. SPCX is loss-making. The pattern fits.
BULL MSCI inclusion arrives around the same time, bringing institutional demand that could absorb the new supply. And if Starship has confirmed commercial launches by this point, the revenue picture looks entirely different. A company with a $25 billion-plus revenue trajectory is a different proposition to a company burning $4 billion a quarter. Context matters.
MARK'S LEAN Here's the catch. Those institutional buyers from MSCI inclusion have to actually show up. The 28% unlock lands regardless of whether they do. If Q3 numbers still show losses close to Q1 levels, demand will be cautious and supply will win. This is the event where I would want to be lighter going in and heavier coming out, not the other way around.
How Does SPCX Fit Your Portfolio?
If you're holding SpaceX or thinking about it, we'll show you how it sits against your existing positions. Free portfolio review, no strings.
Book a Portfolio ReviewBULL By June 2027, we will have twelve months of public earnings data. If profitability is on the visible horizon, the S&P 500 inclusion review becomes plausible. And that is a forced-buying event that makes QQQ inclusion look like a rounding error. If Musk signals publicly that he will not sell, this stops being a supply event and starts being a sentiment catalyst. Markets love certainty, even if the certainty is just one man saying he is staying.
BEAR Markets price the overhang weeks before the actual date. If Musk stays quiet, expect suppressed price action and elevated options volatility through May and June 2027. The overhang exists whether or not it actually materialises. And Musk has a track record of selling Tesla stock when nobody expected it. You do not get to assume he will hold just because he says he loves the company.
MARK'S LEAN This is the longest-dated event on the list and the hardest to handicap today. Too much changes between now and June 2027. But if the stock survives the Q3 unlock in November and earnings are trending in the right direction, the Musk lockup becomes more noise than signal. If the stock is already wounded by then, it becomes the final blow.
The Verdict
The bull cases require things to go right in sequence. Starship working. Earnings improving quarter over quarter. Institutional demand absorbing each lockup tranche on cue. It is a chain of events where each link depends on the one before it.
The bear cases only need one thing to go wrong at the wrong moment. One bad Starship flight. One ugly earnings print. One lockup tranche that overwhelms demand. And at 100 times sales, there is no valuation floor to catch you on the way down.
Watch July 3 first. Starship either sticks the landing or it doesn't. The answer to that question shapes how every single event after it gets interpreted by the market.
Five dates. Twelve months. One of the most asymmetric setups in years.

When does SpaceX join the Nasdaq-100?
SpaceX (SPCX) is expected to join the Nasdaq-100 on July 6-7 2026. This happens under the fast-track Day 15 inclusion rule that applies to mega-cap IPOs, which allows companies to enter the index just two weeks after listing. Index funds tracking the QQQ will need to buy between $7 billion and $14 billion of SPCX shares in a market-on-close auction. With the free float at just 4.3%, that forced buying creates extreme concentration into a very thin market.
When is the next Starship launch?
Starship Flight 13 is targeting early July 2026, likely around July 3, pending FAA clearance. Flight 12 ended with a booster loss during descent, so the FAA review is the gating item before the next attempt can proceed. A clean Flight 13 with a successful booster catch would be significant for the investment case, particularly because Blue Origin's competing New Glenn rocket exploded on the pad in May 2026, leaving SpaceX with an even stronger monopoly position in heavy-lift launch services.
When do SpaceX insider lockups expire?
SpaceX insider lockups expire on a staggered schedule designed to prevent a single massive sell event. The first 20% unlocks after Q2 earnings in August 2026. After that, 7% tranches unlock every 15 days through to October. A further 28% unlocks after Q3 earnings in November 2026. The general 180-day lockup expires on December 9 2026, releasing any remaining locked shares. Elon Musk has a separate, longer 366-day lockup that expires on June 13 2027. By the end of September 2026, the available float will be roughly six times the IPO float.
Will SpaceX join the S&P 500?
Not soon. The S&P 500 requires four consecutive quarters of GAAP profitability before a company becomes eligible for inclusion. SpaceX reported a loss of $4.28 billion in Q1 2026 and has never posted an annual profit. Even in an optimistic scenario where the company reaches profitability by late 2026, the earliest it could meet the four-quarter requirement would be mid-2027, with a realistic inclusion date in 2028 or later. The S&P index committee also exercises discretion beyond the minimum criteria, so meeting the threshold does not guarantee inclusion.
What happens when Elon Musk's SpaceX lockup expires?
Elon Musk's 366-day lockup expires on June 13 2027, about six months after the general insider lockup. Markets typically begin pricing the overhang weeks before the actual expiry date, which means you can expect suppressed price action and elevated options volatility through May and June 2027. If Musk publicly signals that he will not sell, the event could flip into a sentiment catalyst. If he stays quiet, the overhang effect persists whether or not he actually sells any shares. He has a track record of selling Tesla stock without warning, so the market will not give him the benefit of the doubt unless he makes a clear statement.
