US equity-index futures rose on October 21, 2026, as strong results from some of the biggest beneficiaries of the artificial intelligence boom revived optimism over the tech trade. Nasdaq 100 futures climbed 0.7% after SpaceX reported quarterly net income that more than doubled estimates, sending its shares up around 7% in extended trading. S&P 500 futures rose 0.2% after the underlying benchmark advanced 0.3% on Tuesday. Futures for Australia, Japan and South Korea also pointed to gains, according to the Bloomberg markets wrap published October 21, 2026.
The numbers behind the move were striking. SpaceX, now described as Elon Musk's satellite, rocket and AI conglomerate, posted $4.4 billion in net income for the quarter ended September against an analyst average estimate of $1.88 billion. Revenue surged 161% from a year earlier and also beat expectations. Super Micro Computer topped expectations too, surging 15% in post-market trading and lifting AI-infrastructure shares, while Netflix fell after issuing a disappointing forecast.
The results offered some reassurance after concerns over AI valuations and financing rattled technology shares last week. Tim Waterer, chief market analyst at KCM Trade, said clear earnings beats and constructive corporate updates are helping to ease the AI anxiety that has surfaced in recent sessions, but framed the next test explicitly: if Meta and Tesla deliver similarly strong results and guidance when they report Wednesday, it could reignite broader AI enthusiasm and give the sector more sustained momentum.
A structural wildcard now sits alongside the earnings test. Musk said SpaceX and Tesla have formed special committees to explore a potential merger, a preliminary step toward what would rank as the largest corporate tie-up of all time. That announcement landed separately from the earnings beat, and it ties the fate of the AI trade's most-watched report card to a deal whose terms, structure and regulatory path remain entirely undefined.
Not everyone is convinced. Billionaire Ken Griffin said investors are almost certainly in the midst of an AI bubble, with many companies still grappling with how much to spend on the technology and its potential to transform the economy. The caution has market fingerprints: in Australia, data-center developer Nextdc plunged 44% after cutting its outlook and renewing its capital expenditure program, and in South Korea, AI infrastructure company Elice slumped 32% on its trading debut, one of the country's worst on record.
The macro backdrop is shifting too. Long-term Treasuries advanced Tuesday as oil retreated from recent highs, with yields from 10 to 30 years falling three to four basis points and the benchmark 10-year rate declining to 5.11%. Izaac Brook, US rates strategist at RBC Capital Markets, said the AI risk-off trade that bubbled up last week is still top of mind in rates markets and appears to be driving price action, though the move lower in oil also helped pressure yields. Brent crude settled near $109 a barrel after a choppy session shaped by conflicting headlines on efforts to end the US-Iran war.
A new wrinkle came from the Federal Reserve. Chicago Fed President Austan Goolsbee said on October 21, 2026 that inflation fueled by the AI boom is crossing the line and starting to drive up prices in previously unrelated areas of the economy. He pointed to sharp rises in land, electricity, water, infrastructure construction and electrical components needed for data centers, said he is increasingly concerned this is classic aggregate demand overheating, and suggested that if inflation remains persistently high the answer to what the Fed should do is self-evident. He noted such increases have not yet passed through to consumer items like groceries and haircuts.
The setup for Wednesday is therefore a collision of three forces: earnings that must justify billions poured into computing infrastructure, a merger exploration that could redraw the corporate map of the AI economy, and a central bank openly debating whether the boom itself is an inflation problem. Anthropic's reported potential $750 billion in additional computing spend, per a Wall Street Journal report, underscores how much capital is riding on the answer. If Meta and Tesla deliver, the AI trade regains momentum; if they stumble, last week's risk-off move may resume with a Fed warning attached.
Why it matters
Meta and Tesla report Wednesday with AI sentiment fragile after last week's selloff. SpaceX's beat and the merger-committee news raise the stakes, while a Fed president's warning that AI is driving inflation adds a policy dimension that could outlast any single earnings report.
Builder angle
For builders, the signal is that AI infrastructure costs are now a macro story. Goolsbee's list of rising input prices, land, power, water and electrical components, is a pricing-power map for anyone selling into data-center supply chains, and the SpaceX-Tesla committee news shows corporate structure itself is becoming a lever in the AI race.
What to watch next
Meta Platforms and Tesla earnings on Wednesday, October 22, 2026, including any guidance on AI capital spending. Any further detail on the SpaceX-Tesla merger committees. The Fed's policy meeting later this month, where Goolsbee's inflation concerns will be tested against his colleagues' views.
