Summary

IBIT Options Limits Raised to 250,000
If you trade options on the iShares Bitcoin Trust ETF (IBIT), BOX increased the per-side position and exercise limits from 25,000 contracts to 250,000 contracts. This change became operative upon filing on August 15, 2025.
Exchange Says Liquidity and Hedging Improve
BOX states that increasing IBIT position limits to 250,000 contracts should create a more liquid and competitive market for IBIT options, let institutional investors use IBIT options for hedging, and reduce incentives for participants to move trades to opaque over-the-counter (OTC) markets.
Reporting and Surveillance Requirements Stay
BOX will keep its existing reporting and surveillance rules for IBIT options. Member firms must still report positions and hedging information, customer large-position reporting will remain at 200 contracts, and Market Makers remain exempt from the reporting requirement though the Exchange may access their position data.
Position Limits Will Be Reviewed Every Six Months
IBIT will be removed from the IM-3120-2 table and, under BOX rules, its position and exercise limits will be subject to six-month reviews to determine future limits. The Exchange will review limits under Rule 3120(e) on the same schedule as other options.
