NYSE Arca, with SEC approval, has eliminated the 25,000-contract position limit cap and lifted trading restrictions on flexible-settlement options (FLEX options) for eleven major Bitcoin and Ethereum ETFs. The rule change took effect immediately upon filing on March 10, 2026 — no waiting period required.

Key Points

  • What: NYSE Arca removed the 25,000-contract position and exercise limit for most crypto ETF options and opened all listed crypto ETF options to FLEX trading
  • Who: Options traders and investors in Bitcoin and Ethereum ETFs including IBIT, FBTC, ARKB, ETHA, FETH, GBTC, BTC, BITB, ETHE, ETH, and ETHW
  • When: Operative immediately upon filing (March 10, 2026); comment period open until April 13, 2026
  • Impact: Institutional and sophisticated traders can now hold larger options positions and use customizable FLEX contracts on crypto ETFs, potentially increasing market liquidity and flexibility

What Changed and Why

When crypto ETF options first launched on NYSE Arca in late 2024 and early 2025, the exchange imposed a 25,000-contract ceiling on positions — a conservative guardrail while regulators got comfortable with a new asset class.

That cap is now gone for most products. Specifically, the 25,000-contract limit has been removed for:

  • Fidelity Wise Origin Bitcoin Fund (FBTC)
  • ARK21Shares Bitcoin ETF (ARKB)
  • Grayscale Ethereum Trust ETF (ETHE)
  • Grayscale Ethereum Mini Trust ETF (ETH)
  • Bitwise Ethereum ETF (ETHW)
  • iShares Ethereum Trust ETF (ETHA)
  • Fidelity Ethereum Fund (FETH)

Position limits for these products will now follow standard NYSE Arca rules (Rule 6.8-O), the same framework applied to all other equity options — meaning limits scale based on the underlying's float and trading volume rather than a fixed ceiling.

For GBTC, BTC (Grayscale Mini), BITB, and IBIT, which had already received expanded treatment in mid-2025, the new rules remove the special aggregation requirement that counted FLEX and non-FLEX positions together. Going forward, these are treated like any other options — a simpler, more standard approach.

FLEX Options: Now Fully Open

FLEX options (Flexible Exchange Options) allow traders to customize key contract terms — expiration dates, strike prices, and settlement style — within limits. Previously, only a handful of the crypto ETFs (GBTC, BTC, BITB, and IBIT) were allowed FLEX trading.

This rule change removes the carve-out that blocked the remaining Ethereum and Bitcoin ETFs from FLEX trading. All eleven crypto ETFs now qualify for FLEX options on equal footing with standard equity options.

The SEC waived the normal 30-day waiting period, citing consistency with other exchanges (Nasdaq ISE, MIAX, and Nasdaq PHLX had already made similar changes) and the absence of novel regulatory issues.

What You Should Do

If you're an options trader or institutional investor in crypto ETFs: the expanded position limits and FLEX access could meaningfully change your hedging and strategy options. Check with your broker or advisor on how the new limits apply to your current positions.

For most retail investors, no immediate action is needed — but this signals continued regulatory normalization of crypto ETF derivatives, which could affect pricing and liquidity in products you already hold.
