This is a niche market topic focused on specific pop culture (K-Pop). For K-Pop fans, this is a very standard and hot topic; however, for the general public or pure financial traders, it falls into a relatively exotic and entertainment-oriented category. Especially since 2026 is a critical juncture for contract renewals or hiatus periods for many groups (like Blackpink's activity status), this question involves industry speculation beyond simple release predictions.

Comeback plans of K-Pop groups directly impact the stock prices of their respective listed entertainment agencies. These groups (e.g., Blackpink for YG, NewJeans for HYBE, Twice for JYP) are core revenue drivers. Specifically, whether Blackpink releases a new song as a full group in 2026 has a significant impact on YG Entertainment (KOSDAQ: 122870), as the market relies heavily on their IP value. For other agencies, while the impact of a single group might be smaller, it still serves as a catalyst for stock volatility.

April 26, 2026 - April 28, 2026, NewJeans' price surged from 20.5c to 64.5c, driven by ADOR's official confirmation that some members are in Copenhagen for new music pre-production, vastly boosting expectations for a 2026 release. April 15, 2026 - April 16, 2026, Twice's price crashed from 93c to 68.7c before partially rebounding to 81.15c in the following days, likely driven by rumors or insider hints that the group will focus predominantly on solo or sub-unit activities in 2026, drastically lowering the probability of a full-group release. April 9, 2026 - April 10, 2026, NewJeans' price crashed from 47c to 17.5c, driven by worsening conflicts between HYBE and ADOR, leading to extreme market fears of a complete halt in their yearly activities. April 8, 2026 - April 11, 2026, Le Sserafim's price recovered from 79.3c to 98.45c, and Itzy's price rebounded from 75.65c to 98.4c, as the market quickly corrected from a brief panic sell-off or liquidity shock back to the fundamental certainty of top girl groups releasing songs. April 3, 2026 - April 6, 2026, Le Sserafim's price surged from 70.65c to 96.95c, as the market aggressively corrected previous undervaluation to align with the fundamental certainty of annual releases for top girl groups. April 4, 2026 - April 6, 2026, Itzy's price surged from 72.5c to 95c, similarly driven by a market correction aligning with JYP Entertainment's regular comeback schedules. March 29, 2026 - March 31, 2026, Twice's price corrected from 93.5c to 83.5c without major fundamental deterioration, likely due to high-level profit-taking. March 19, 2026 - March 20, 2026, Illit's price surged from 81.5c to 94.5c, likely due to an official comeback teaser or media confirmation of Q2 plans, eliminating uncertainty. March 5, 2026 - March 6, 2026, (G)I-DLE crashed from 89c to 49c, and Le Sserafim crashed from 86.5c to 50.5c, likely due to a liquidity crunch or panic selling on rumors, causing prices to default to the uncertainty median of 0.50.

Polymarket currently prices NewJeans at 64.5c, yet ADOR has officially confirmed that the group is undergoing pre-production for new music in Copenhagen. Mainstream media and industry consensus interpret this as a highly probable 2026 comeback. The market may not have fully priced in this highly certain official statement, indicating an undervaluation divergence.
