India’s Competition Commission (CCI) exposed a cement cartel in 2026 through digital forensics revealing coordinated “lucky number” price signals shared via WhatsApp, emails, and calls among giants like UltraTech, Dalmia, and ACC—leading to massive fines for anti-competitive conduct.
From Raids to Digital Evidence
CCI raids in 2020 uncovered “kiln closure” pacts and district-wise price charts circulated to enforce uniform hikes, bypassing competition in eastern/southern markets. Private IT experts decoded seized phones showing executives using coded language like “lucky numbers” for price floors, mirroring 2010 Builders Association case where CMA facilitated similar collusion.
Major Players and Penalties
UltraTech, Ambuja, ACC, Shree Cement, Nuvoco, and Dalmia faced Rs 6,307 crore penalties—the largest antitrust fine in India—after DG probe confirmed bid-rigging in ONGC tenders via middlemen. Recent 2025 scrutiny demanded 9-year financials, spotlighting India Cements’ collusion.
Industry-Wide Wake-Up Call
Oligopolistic cement sector—hit repeatedly since 2007 MRTP probes—now faces stricter monitoring amid infrastructure boom, with FM Sitharaman noting parallel steel cartel inquiries. CCI’s tech-driven enforcement signals zero tolerance for digital cartels inflating construction costs.
