On May 20, Cerebras Systems rose 7.45% in regular trading, trading at $327.14/share, with trading volume of $299 million.

On the news front, S&P Dow Jones Index confirmed that Cerebras meets the large IPO fast-track rapid inclusion rule, with the effective date set for May 25. Given that tens of trillions of dollars globally track S&P indices, index funds must allocate the stock by weight, creating significant passive buying pressure. Analysts noted the inclusion will substantially boost the stock's visibility among passive fund managers.

Additionally, ARK Invest ETFs rapidly built positions exceeding 105,000 shares post-IPO, signaling strong institutional appetite for AI infrastructure. A prior market misinterpretation of executive Form 4 filings — mistakenly viewed as insider selling when the transactions were actually tax-related share withholdings on RSU vesting — has also been clarified, restoring sentiment.

Cerebras debuted on Nasdaq on May 14 at $185/share, raising approximately $5.55 billion in the largest tech IPO in recent years. The company reported revenue of $510 million, up 76% year-over-year, and achieved profitability with net income of $238 million.
