MIAX Sapphire has filed a proposed rule change with the U.S. Securities and Exchange Commission (SEC) to enable options trading on the VanEck Bitcoin Trust, marking a pivotal step in expanding regulated crypto derivatives. The filing, submitted on July 31, 2025, aims to amend Exchange Rule 402 to include the trust as an eligible underlying security for options contracts. This move follows a competitive push by Cboe Exchange, which has also sought similar approvals, signaling a race to dominate the emerging Bitcoin ETF derivatives market.
The VanEck Bitcoin Trust, structured as a commodity-based ETF, holds Bitcoin as its primary asset and provides investors with exposure to Bitcoinβs price movements without direct ownership. MIAX Sapphire argues that listing options on this trust will enhance market competition and align with existing SEC precedents, such as the approval of CboeBZX-2023-040 for Bitcoin-based trust shares. The proposal emphasizes the trustβs compliance with initial listing standards, including substantial outstanding shares and a broad investor base.
MIAX Sapphire’s Regulatory Push
MIAX Sapphireβs filing underscores its strategic focus on crypto derivatives. The exchange, part of the MIAX Global network, has positioned itself as a leader in innovation, with this proposal building on its earlier efforts to integrate blockchain-based assets into traditional markets. By targeting the VanEck Bitcoin Trust, MIAX aims to capitalize on the growing institutional demand for Bitcoin exposure through regulated instruments.
The proposed amendment to Exchange Rule 402 aligns with Section 19(b)(1) of the Securities Exchange Act of 1934 and Rule 19b-4, ensuring compliance with federal securities laws. MIAX Sapphireβs legal justification draws parallels to prior SEC approvals, reinforcing the argument that Bitcoin ETFs are suitable for options trading.
VanEck Bitcoin Trust’s Market Position
The VanEck Bitcoin Trust has established itself as a key player in the Bitcoin ETF landscape, offering a cost-efficient alternative to direct Bitcoin ownership. As of recent filings, the trust has demonstrated robust liquidity and investor participation, with a substantial number of beneficial holders. Below is a summary of its investor base growth:
| Date | Beneficial Holders |

Cboe’s Competitive Countermove
Cboe Exchange has emerged as a direct competitor to MIAX Sapphire, submitting its own application to list Bitcoin ETF options. This dual push highlights the broader industry trend toward institutional adoption of crypto derivatives. Both exchanges aim to leverage the SECβs openness to Bitcoin ETFs, which gained momentum after the approval of spot Bitcoin ETFs in 2023.
Analysts note that the SECβs response to these filings will set a precedent for future crypto derivatives products. A favorable ruling could accelerate the development of Bitcoin options markets, potentially driving increased volatility and liquidity in the underlying asset.
MIAX Sapphireβs proposal also addresses concerns about market manipulation, emphasizing the trustβs alignment with existing commodity-based ETF standards. The exchange argues that the VanEck Bitcoin Trustβs structure mitigates risks associated with direct Bitcoin ownership, making it suitable for options trading.
Regulatory clarity remains a critical factor. The SECβs accelerated approval process for CboeBZX-2023-040 suggests a willingness to support innovation in crypto derivatives, provided filings meet rigorous standards. MIAX Sapphireβs application follows this precedent, reinforcing the trustβs eligibility under Exchange Rule 402.
Market participants anticipate that the introduction of Bitcoin ETF options could attract new institutional investors, particularly those seeking hedging tools. This development aligns with broader trends in the crypto market, where derivatives trading has become a dominant force.

Market Impact: If approved, MIAX Sapphireβs proposal could significantly expand the Bitcoin derivatives market, offering investors new ways to gain exposure to Bitcoinβs price movements. This may lead to increased institutional participation, further legitimizing Bitcoin as a mainstream asset class. However, critics caution that excessive derivatives activity could amplify market volatility, particularly during periods of high leverage.
