Wall Street’s major equity indexes climbed on Wednesday, buoyed by widespread optimism surrounding the artificial intelligence revolution. Investor sentiment received a notable boost as incoming corporate data provided concrete evidence of a return on investment from key players in the sector. Whether this upward trend will maintain its momentum remains the central question for market participants, particularly as more earnings reports and forward-looking guidance from the leaders of the new economy loom on the immediate horizon.

By the closing bell, the tech-heavy Nasdaq Composite rose 1.1% to finish at 26,702. The broad-based S&P 500 added 0.6% to reach 7,757, while the blue-chip Dow Jones Industrial Average advanced 0.7% to close at 52,856.

Price action in the fixed-income market remained relatively muted throughout the session. The 2-year Treasury yield ticked up 2.3 basis points to 4.81%. Meanwhile, yields on the 10-year Treasury inched up 0.6 basis points to 5.123%, and the 30-year Treasury yield drifted downward by 1.2 basis points to 5.413%.

Daniel Skelly, portfolio manager at Morgan Stanley Wealth Management, noted that while recent turbulence in the AI trade may have unnerved some investors, the movement can be interpreted as a healthy development, particularly against a macroeconomic backdrop characterized by solid economic growth and strong corporate earnings.

Skelly acknowledged that current anxieties regarding heavy corporate spending are merited, given the historical boom-and-bust cycles that have accompanied previous waves of U.S. innovation. However, he concluded that the long-term capital expenditure cycle for artificial intelligence remains firmly intact and should continue to favor large, established players with robust balance sheets.

Why a SpaceX-Tesla Merger Is Only a Matter of Time

SpaceX made a commanding debut on the earnings calendar after the closing bell on Tuesday, surging 7.8% following a substantial bottom-line beat. The stellar performance was primarily driven by rapid growth across its Super Intelligence and Starlink segments.

Yet, the most significant revelation of the day came from CEO Elon Musk, who addressed the prospect of what could become the largest mergers and acquisitions transaction in the history of the stock market: a long-rumored consolidation between SpaceX and Tesla, which saw its shares rise 3.4%.

According to Musk, the boards of directors at both SpaceX and Tesla have formally established special committees to evaluate a potential merger between the two entities.

"I do think there’s a lot of merit to combining the companies," Musk stated during a conference call with analysts and investors to discuss SpaceX’s financial results. "There’s a lot to be gained from cooperating on developing superintelligence software."

While predicting future corporate transactions is notoriously difficult, available indications suggest that the probability of the boards at SpaceX and Tesla aligning with their CEO’s vision is significantly higher than alternative outcomes.

What That Deal Means for AT&T

AT&T also delivered its third-quarter financial results, beating consensus expectations on both the top and bottom lines. Management responded to the strong performance by raising its full-year earnings guidance and accelerating the telecommunications giant’s stock buyback program.

Revenue for the quarter climbed 5.3% year-over-year to reach $32.3 billion, comfortably topping the consensus estimate of $31.7 billion compiled by FactSet. Earnings per share came in at 65 cents, beating expectations of 60 cents. Furthermore, AT&T projected that its earnings per share for 2026 will reach $2.40, marking an upward revision from the previous guidance range of $2.25 to $2.35 issued in July.

"The accelerated growth we delivered this quarter shows our structural advantages to lead the next era of connectivity," CEO John Stankey said in a public statement. "We are accelerating the pace of our planned share repurchases this year to approximately $10 billion, reflecting our confidence in our market position."

Despite these positive metrics, the blue-chip dividend stock suffered a sharp decline on Wednesday. The sell-off was triggered by AT&T’s report of 379,000 net new postpaid subscribers, which narrowly missed the consensus forecast of 379,300 additions and represented a deceleration from the 432,000 new subscribers added during the second quarter.

Postpaid subscribers are vital to telecommunications providers because they generate predictable, long-term recurring revenue. Any deterioration in this metric serves as an indicator of intensifying competitive pressures from existing market participants, such as Verizon Communications, which fell 2.2%, and T-Mobile US, which declined 2.5%. Shares of AT&T dropped 6.5% on the day.

Beyond traditional telecom rivals, financial markets are also pricing in the potential threat posed by emerging market-share contenders, such as SpaceX. Shares of AT&T, down 4.7% through October 20 compared to a modest 0.7% drop for the S&P 500, alongside Verizon and T-Mobile, have all faced downward pressure since October 8. On that date, SpaceX accelerated its plans to launch a consumer wireless telecom business backed by an $8 billion spectrum acquisition designed to allow Starlink to compete directly with traditional terrestrial carriers.

Tesla and fellow Magnificent Seven stock Meta Platforms prepared to report their own third-quarter financial and operational results after the closing bell. Independent tech analyst Luke Lango expressed particular optimism regarding Meta’s positioning.

"Meta heads into earnings as a frontier AI contender, not just an ad company, and the market hasn’t fully priced that shift," Lango observed. "The core business is humming, and we expect revenue to clear the $63.3 billion consensus by $1 billion or more on growth north of 20%, a pace few mega caps can touch."

According to Lango, Meta’s newly launched Muse application represents a pivotal narrative for the company, noting that the artificial intelligence agent surpassed 10 million downloads in approximately six weeks—a launch velocity achieved by only a dozen apps in history.

Lango pointed to SpaceX’s recent financial results as broader evidence that intelligent software agents and the immense computing power required to support them are already generating tangible revenue. In his view, this reality fundamentally reframes the ongoing debate surrounding capital expenditures.

"When compute is this scarce and this valuable," Lango wrote, "a bigger spending plan isn’t recklessness, it’s a land grab."

Looking ahead to Meta’s financial disclosure, Lango anticipated strong digital advertising figures alongside concrete metrics concerning user adoption of Muse. Trading at roughly 20 times projected earnings for the following year, the analyst concluded that Meta represents one of the most cost-effective avenues for investors seeking exposure to the emerging era of artificial intelligence agents.
