APP — Nasdaq-100 index addition

AppLovin (APP) entered the Nasdaq-100 at the close on Dec 22, 2025, replacing GlobalFoundries. The recorded announcement came 10 calendar days before the effective close, on Dec 12, 2025. The company is classified in Information Technology in this dataset. The same ticker also appears in the tracked S&P 500 addition register. That record alone does not establish a transfer between indexes.

In the 30 calendar days leading into the effective close, APP moved +12.5%. The median 30-day run-up among the 14 Nasdaq-100 entries with a recorded announcement and prices for that interval was +12.2%; this stock was 0.3 percentage points above that median. Measured from the effective close, APP returned 1W: -0.7% versus -2.2% for the 14-entry index median; 1M: -4.2% versus +0.8% for the 14-entry index median; 3M: +5.6% versus +5.6% for the 13-entry index median. These figures do not measure movement from the announcement price.

At 1M, it ranks 9th of 14 measured Nasdaq-100 additions and lagged the benchmark by 5.7 percentage points. At 3M, it ranks 7th of 13 measured Nasdaq-100 additions and beat the benchmark by 3.3 percentage points. The 1Y window ends on Dec 22, 2026; a result needs a usable close. The other 8 Information Technology additions with a measured 1M return averaged -5.5%. This is historical context, not a projection.
