Nasdaq will add Lumentum Holdings to its Nasdaq-100 index on May 18, 2026, replacing CoStar Group and extending the benchmark to 100 non-financial companies with over $600 billion in assets under management. The inclusion underlines Nasdaq’s role as an index provider with more than 35,000 benchmarks, potentially boosting future licensing revenue.
1. Index Rebalance Details
Effective May 18, 2026, Lumentum Holdings will join the Nasdaq-100 index in place of CoStar Group following the scheduled quarterly rebalance. The Nasdaq-100 tracks the largest 100 non-financial companies listed on Nasdaq, managing over $600 billion in assets across more than 200 investment products.
2. Implications for Nasdaq
