OKX Opens Pre-Subscription for USDT Yield Event With 1M USDT Pool

The split of the pool toward ETH over BTC is the detail worth noticing: it signals where OKX expects user demand to concentrate, and reward allocation is a soft read on platform incentives rather than a market call. For yield-seeking stablecoin holders, the structure matters more than the headline number, since simple earn interest accrues from pre-subscription while token rewards only count from the official start date, creating a gap between when funds are committed and when the full campaign economics apply. Whether such pre-subscription windows become a standard feature across exchanges is the open question.
