The Most Profitable Crypto Airdrops of the Week: Week 38

Crypto airdrops in week 38: these claim windows are running now This week holds only one date that really bites, and it is now eleven days away. Anyone who held Beldex or Humanity at the crypto exchange Kraken has already been credited with the respective replacement token by airdrop. The only thing left to do with it is to withdraw it, and that option closes on September 25, 2026 at 14:00 UTC. After that the exchange liquidates whatever is left. This is the last full calendar week before that date, and there are two separate notices for two separate tokens: anyone who held both has two things to do. As in the previous week, a warning belongs at the top, because the pattern has repeated itself. Last week it was Holoworld AI, whose claim from September 2025 was circulating through search results as a fresh airdrop. This week it is Meteora (MET). The project confirmed its TGE and airdrop in an announcement dated September 10, from September 10, 2025. The TGE took place on October 23, 2025. Two weeks, two prominent “live” airdrops that actually date from the previous year. That is no coincidence. It is the basic pattern of this field: airdrop announcements display the day and the month prominently and the year almost never. Check it first. This overview lists the airdrops that either have a claim window open this week or have a confirmed date within the next 14 days. Every figure comes from the source linked alongside it, retrieved again on September 14, 2026. Where a project has published no end date, that is stated explicitly. There are no estimated deadlines here. For the state of play a week ago, see our piece on the airdrops of week 37.

Beldex and Humanity: eleven days until forfeiture This entry is the most unusual on the list, because nobody here had to claim anything. Both projects were attacked in June 2026, both responded by rolling out a new token contract and distributing the replacement one for one to holders as of the snapshot. Kraken handled the distribution for its customers and credited it automatically, which is why two additional lines have been sitting in those accounts ever since. An airdrop you never had to claim can still expire. The key data differ by project, and that is the reason for the two separate notices.
