Odaily News: Rodrigo, an official from Polymarket, announced in Discord that the platform will extend its fee mechanism to the college basketball (NCAA) and Serie A markets.

Starting from 00:00 UTC on Wednesday, February 18, 2026, all newly created events related to NCAAB and Serie A after this time will be subject to the new fee mechanism. Existing events will not be affected. The first rebate distribution will occur at 00:00 UTC on February 19.

Odaily News Bitcoin payment application Strike announced on the X platform that it will adjust its margin call policy. Its founder, Jack Mallers, clarified that Strike's loan mechanism will not conduct full liquidation of Bitcoin collateral. When a loan falls below the maintenance margin level, the platform will only perform partial liquidation to restore the loan to a healthy loan-to-value (LTV) ratio of approximately 65%. Jack Mallers added that this mechanism aims to protect users' Bitcoin assets as much as possible while maintaining loan health and buying more time for both customers and the Bitcoin price to recover. Based on this mechanism, the overall liquidation ratio of Strike's loan book is maintained in the low single-digit range of the total outstanding loans, approximately 1%–3%.
