The bigger story is the business mix: the Super Intelligence (SI) segment, previously reported as Artificial Intelligence, now generates more than half of group revenue.
On MEXC,
the SPCXUSDT perpetual contract rose about 8.2% in the five hours after the release, on turnover far above the same window a day earlier, while funding did not rise.
Key Takeaways
SI revenue: $7.56 billion, about 51.9% of total revenue, up 195% quarter over quarter; Cursor, acquired on August 14, contributed $608 million of group revenue during the period.
SI profitability: $431 million in operating income, swinging from a $1.26 billion operating loss in Q2, even after $1.2 billion of Cursor-related share-based compensation.
Capex: SI capex reached $16.444 billion, about 2.18 times SI revenue; group capex of $19.593 billion exceeded group revenue.
Starlink: 13.6 million consumer subscribers, up 1.6 million in the quarter; monthly ARPU rose 5% quarter over quarter to $69, though it remains below $83 a year earlier.
MEXC reaction: SPCXUSDT moved from 148.15 to 160.26 USDT in five hours, first-hour turnover was about 23 times the same hour a day earlier, and the first post-earnings funding settlement was 0%.
Where the Profit Came From
Income from operations was $2.791 billion, so the $4.404 billion net income figure was lifted by items below the operating line.
Those included $873 million of interest income, $1.025 billion of other income (net) and a $390 million income-tax benefit, partly offset by $675 million of interest expense.
Connectivity remained the steadiest profit engine, with revenue of $5.248 billion (up 69% year over year) and operating income of $2.367 billion (up 99%).
The Space segment was close to breakeven, posting $1.767 billion in revenue and a $7 million operating loss as Starship R&D spending rose; the quarter also included SpaceX's first revenue-generating Starship mission.
AI Growth Changes What Investors Need to Watch
SI generated $431 million in operating income, so the next question is whether earnings can scale alongside infrastructure investment.
Nameplate compute expanded to 1.7 GW at September 30 from 1.4 GW at the end of June, and SI capex has now exceeded $15 billion in each of the last two quarters.
The capex-to-revenue comparison illustrates investment intensity; it does not measure cash burn or the eventual return on those assets.
The cash flow statement gives a fuller picture: over the first nine months, operating cash flow was $13.097 billion against $48.069 billion of property and equipment purchases.
That gap is currently funded from the balance sheet, which held $51.294 billion in cash and $38.561 billion in marketable securities at September 30, after $85.675 billion in net IPO proceeds.
Starlink adds another dimension: subscriber growth accompanied by improving sequential ARPU is a stronger operating signal than subscriber growth alone.
Because ARPU is still well below its year-ago level, the next quarters will show whether the sequential improvement holds as the subscriber base expands.
How SPCX Futures Reacted on MEXC
Data snapshot: MEXC Futures, SPCXSTOCK_USDT hourly bars, index-price bars and funding history, retrieved 01:03 UTC on October 21, 2026. Figures will differ at later times.
The window starts with the hourly bar that opened at the 4:00 p.m. ET close on October 20 (20:00 UTC), during which the results came out ahead of the 4:30 p.m. ET call.
Price: SPCXUSDT went from 148.15 USDT at the close to 160.26 USDT by 9:00 p.m. ET, a gain of about 8.2%, while the contract's index price rose about 8.4% over the same five hours.
Trading activity: turnover in the first hour after the close was about 12.09 million USDT, compared with 0.53 million USDT in the same hour a day earlier and an average of 2.10 million USDT per hour over the preceding 24 hours.
Across the five post-earnings hours, turnover totalled about 39.27 million USDT, roughly matching the 37.27 million USDT traded from 9:00 a.m. to 4:00 p.m. ET that day, when the regular US session was open.
This compares an event window with like-for-like hours rather than attributing a rolling 24-hour turnover figure to the earnings release.
Premium to index: during the US session before the release, the contract traded 5–12 basis points above its index price; after the release, it traded at a small discount of up to 10 basis points.
In other words, the move followed the reference price rather than leveraged buyers bidding the contract above it.
Funding: SPCXUSDT settles funding every eight hours; the last settlement before the release (16:00 UTC) was 0.0182%, and the first one after it (00:00 UTC on October 21) was 0%.
The cost of holding a long position did not rise after the earnings jump.
Positive funding, when it appears, means longs pay shorts; it is a carrying-cost signal, not a count of bullish versus bearish traders.
Following SPCX Through MEXC
A useful assessment pairs price changes with funding, trading activity and the premium to index, rather than treating a rising contract price as sufficient evidence of sustained demand.
