Quantum Breakthrough or Bubble? Rigetti Stock Rockets 5,000% in 2025
Rigetti Computing shares soared nearly 5,000% in 2025, peaking at $56 in mid-October before dropping to the high $30s. The company won a $5.8 million U.S. Air Force contract and launched a 36-qubit processor, but Q2 revenue was just $1.8 million against a $39.7 million net loss. Market cap reached $12–17 billion, drawing analyst warnings of overvaluation. U.S. policy speculation fueled further volatility.
