First-order effects

• Cerebras can seek more proceeds and a higher initial valuation if it formally raises the range, while investors who want shares face tighter allocations because orders exceed available stock.
• The underwriting group gains evidence to support a more aggressive price-setting process, rather than relying on the original range as the ceiling.

Second-order effects

• A higher range and oversubscribed book can pull additional demand into the offering, but also raise the bar for post-listing performance once scarcity-driven IPO demand gives way to public-market trading.
• The subsequent upsizing and final price above the later range suggest that early order strength translated into materially greater fundraising capacity for Cerebras.

Third-order effects

• If similar demand patterns persist, IPO issuers with strong institutional books may increasingly test higher prices and larger deal sizes before listing, shifting more value capture from first-day trading into the offering itself.
• The later margin warning and share decline indicate that a strong IPO book does not remove the longer-term market emphasis on operating performance; public valuations can reset quickly when that evidence changes.
