Derivatives trading platform Variational Omni launches public mainnet

Variational's derivatives trading platform Omni exited private beta and launched its public mainnet on November 12, removing the referral code requirement for registration. The platform, which began private testing in January 2025, reported over $1.5 billion in open interest and more than $450 billion in cumulative trading volume. Omni now offers access to over 550 traditional finance and crypto markets and has made zero trading fees a permanent rule following the private testing period. The public launch matters as it opens a high-volume, fee-free derivatives venue to retail users without gating. What to watch next is whether open interest and volume sustain their growth now that registration is unrestricted.
