Nasdaq Slides 1.5% as Inflation Fears Return; Cerebras Surges 68%
Published on May 15, 2026
Wall Street faced renewed selling pressure on Thursday as the Nasdaq Composite slid 1.5%, extending its recent pullback amid growing concerns that inflation may be staging a comeback. The Dow Jones Industrial Average also fell 1%, reflecting broad-based weakness across sectors. The moves came as U.S. equity futures pointed to further declines, with traders bracing for a potentially hawkish shift in Federal Reserve policy.
Inflation Fears Resurface
The latest sell-off was triggered by a hotter-than-expected producer price index (PPI) report, which reignited fears that the Fed's battle against inflation is far from over. The data showed a surprise uptick in wholesale prices, driven by rising energy and food costs. This follows a string of resilient economic data that has kept the central bank on edge. Market participants are now pricing in a higher probability of rate hikes later this year, a stark contrast to the dovish expectations that fueled the rally in early 2026.
“The market is grappling with the reality that inflation may not be as transitory as hoped,” said Sarah Thompson, a senior economist at Vertex Analytics. “The Fed’s next moves will be critical, and any hint of tightening could trigger further volatility.”
Cerebras Systems Soars in Nasdaq Debut
Amid the broader sell-off, Cerebras Systems provided a bright spot for tech investors. The AI chipmaker surged 68% in its Nasdaq debut, closing at $78.40 per share, well above its IPO price of $46. The strong debut underscores the insatiable demand for AI-related stocks, even as the broader market struggles. Cerebras, known for its massive wafer-scale chips, has positioned itself as a key player in the AI hardware race, competing with Nvidia and AMD.
The company’s IPO raised $1.2 billion, making it one of the largest tech listings of the year. Analysts attribute the pop to a combination of strong fundamentals and a scarcity of pure-play AI chipmakers in the public markets. “Cerebras offers a unique value proposition, and investors are willing to pay a premium for exposure to the AI revolution,” said Michael Chen, an IPO strategist at Renaissance Capital.
SpaceX IPO Prospectus Could Drop Next Week
In another development that could reshape the market landscape, sources indicate that SpaceX’s IPO prospectus could be released as soon as next week. The highly anticipated offering is expected to be one of the largest in history, with valuations exceeding $200 billion. SpaceX’s Starlink division, which provides satellite internet, has been a key growth driver, and the company’s Starship program continues to attract attention.
If SpaceX goes public, it would provide a major catalyst for the Nasdaq and could reignite interest in the space and technology sectors. However, some analysts caution that the timing of the IPO, amid inflation fears and market volatility, could temper initial gains. “SpaceX is a unique asset, but market conditions will play a big role in its debut,” noted Laura Bennett, a portfolio manager at Horizon Investments.
Original Commentary: A Tale of Two Markets
The juxtaposition of Cerebras’ meteoric rise and the Nasdaq’s decline highlights a growing divergence in the market. While AI and space-themed stocks continue to attract speculative capital, the broader market is weighed down by macroeconomic headwinds. This bifurcation suggests that investors are increasingly selective, favoring companies with disruptive technologies over traditional growth stocks. Historically, such periods of divergence have often preceded market corrections, as speculative excesses in certain sectors can mask underlying fragility.
Looking ahead, the key risk is that the Fed may be forced to act more aggressively if inflation persists. This could lead to a sharp repricing of risk assets, particularly those with high valuations and no earnings. Investors should monitor the PCE data due next week for further clues on the inflation trajectory.
