Shares rallied 14.3% as investors rewarded Lightwave Logic’s materially expanded market opportunity and traction with multiple large customers amid robust AI-driven demand surging the total addressable market (TAM) significantly beyond prior estimates.

• The 2028 combined AI and data center optical transceiver TAM jumped from $17 billion to approximately $47 billion, reflecting rapidly increasing bandwidth requirements driven by AI infrastructure growth.
• The serviceable addressable market (SAM) for electro-optic polymer modulators widened to $2 billion–$4 billion, up from $1 billion–$2.5 billion last year.
• Lightwave Logic now counts four major Stage 3/prototyping customers, all Fortune 500 or Global 500 firms, with additional Tier 1 customers expected to reach this milestone by Q3 2026.
