Cerebras raises $5.5B in comeback IPO

Cerebras nearly died. Then raised $5.5B died — The chip maker everyone wrote off just kicked off 2026's IPO season

THE COMEBACK

From near-bankruptcy to $5.5B valuation in 12 months. A year ago Cerebras was scrambling for bridge funding. Today they opened at $42 per share, pricing above range. Wall Street is betting big on AI chips that aren't Nvidia.

Step 01: Build wafer-scale chips

Cerebras makes chips the size of dinner plates. One wafer holds 850,000 cores vs Nvidia's 80. The physics shouldn't work but somehow does. They ship to 14 countries now.

Step 02: Survive the trough

Mid-2025 their biggest customer went dark. Burn rate hit $60M per quarter. Founders took zero salary for 8 months. Three board members quit. The pivot to inference chips saved them.

Timing beat technology Timing

  • Nvidia lead times hit 11 months in Q1 2026
  • Inference costs became the new bottleneck
  • Enterprises want chip diversity for leverage

The market opened because Nvidia couldn't ship fast enough

03. What this signals

First major AI hardware IPO since the GPU shortage began. If Cerebras holds above $40, expect Groq and SambaNova to file by Q3. The AI infrastructure layer is finally liquid.

The bottom line
