According to Eric Balchunas, IBIT options open interest has reached $38 billion and IBIT has surpassed Deribit as the largest venue for bitcoin options (source: Eric Balchunas on X, Oct 2, 2025). According to Eric Balchunas, this underscores that ETFs are materially impacting options activity and that "fat crypto margins" are in trouble (source: Eric Balchunas on X, Oct 2, 2025). According to Eric Balchunas, the data point was surfaced by Sidharth Shukla (source: Eric Balchunas on X, Oct 2, 2025).

According to the source, U.S. regulators at the SEC and CFTC are moving to harmonize crypto rules, signaling that a turf war is over (source: source post on X dated Sep 30, 2025). According to the source, BlackRock’s IBIT has surpassed Deribit to become the largest venue for Bitcoin (BTC) options (source: source post on X dated Sep 30, 2025). According to the source, Swift and Visa are using blockchain to address cross-border payments (source: source post on X dated Sep 30, 2025). Trading implications: If confirmed by primary releases from the SEC, CFTC, BlackRock, Swift, and Visa, traders should monitor BTC options open interest and implied volatility across U.S.-listed ETF options versus crypto-native venues, dispersion between BTC spot and derivatives basis, and headline risk around regulatory harmonization that could shift liquidity toward regulated venues.

According to the source, Bloomberg reports BlackRock’s iShares Bitcoin Trust (IBIT) has become the largest BTC options venue with nearly 38 billion dollars in open interest, overtaking Deribit at roughly 32 billion dollars, according to Bloomberg. Bloomberg states these figures offer traders a concrete benchmark to track positioning and liquidity in BTC options.

According to @GreeksLive, notional block trade volume totaled $720,519,908 for Sep 22-28, with $470.0 million executed on Deribit and $250.6 million on OKX; a recap of the top 5 block trades is available via greeks.live, source: @GreeksLive on X, Sep 29, 2025. Deribit and OKX accounted for approximately 65.2% and 34.8% of the reported weekly flow respectively, based on figures reported by @GreeksLive on X, Sep 29, 2025.

According to @GreeksLive, weekly notional block trading volume totaled $483,765,238 from Sep 15 to Sep 21, 2025, with $402.7 million on Deribit and $81.1 million on OKX (source: @GreeksLive). Based on these figures, Deribit accounted for about 83% of the week's block volume and OKX about 17%, with an average daily notional of roughly $69.1 million (source: @GreeksLive). @GreeksLive also noted a published recap of the top 5 block trades for the week on greeks.live for further detail (source: @GreeksLive).

According to the source, BTC options markets show traders paying up for downside protection as put prices outpace calls while 30-day implied volatility sits near a two-year low, indicating elevated demand for hedges despite subdued vol (source: Deribit). This positioning contrasts with supportive macro tailwinds cited in the market, including a recent U.S. policy rate cut and the SEC’s accelerated handling of crypto ETF filings (sources: Federal Reserve; U.S. SEC). For execution, the rich put skew versus low overall IV favors cost-controlled structures such as bear put spreads or protective collars over outright long puts to mitigate theta and skew costs (source: Deribit). Near-term risk management should account for potential sharp moves where skew implies improved downside payoff asymmetry if BTC weakens, while low IV increases carry risk if spot remains stable (source: Deribit).

According to @GreeksLive, from September 1 to September 7 the platform facilitated USD 497,448,991 in notional crypto options block trade volume, including USD 341.5 million on Deribit and USD 155.9 million on OKX (source: @GreeksLive).

According to @Andre_Dragosch, BlackRock’s tokenized money market fund BUIDL has begun trading on Deribit, which was recently acquired by Coinbase. This move signals further institutional adoption of tokenized assets within the crypto ecosystem, potentially increasing liquidity and trading opportunities for digital asset investors. The entry of a major traditional finance player like BlackRock into tokenized fund trading could impact both DeFi and CeFi markets by bridging traditional and crypto financial products (source: @Andre_Dragosch).

According to Henri Arslanian, regulatory uncertainty stands as the biggest challenge for crypto CEOs in acquiring new clients, as discussed in his interview with Luuk Strijers, CEO of Deribit. Strijers highlights how evolving compliance demands and differing global regulations complicate onboarding processes, impacting trading volumes and market participation. This regulatory landscape directly influences client trust and the speed at which exchanges like Deribit can scale, ultimately affecting liquidity and price discovery in crypto derivatives markets (source: Henri Arslanian interview with Luuk Strijers).

According to Greeks.Live, the platform recorded a notional trading volume of $277,199,832 ($277 million) in block trades from July 21st to July 27th, 2025. Of this total, $246.9 million was executed on Deribit and $30.3 million on OKX, reflecting robust institutional activity in crypto derivatives markets. This high volume signals continued trader interest and liquidity in Bitcoin and Ethereum options, potentially impacting volatility and pricing strategies for active traders (source: Greeks.Live).

According to @GreeksLive, the platform facilitated $309 million in notional trading volume through block trades for the week of July 14th to July 20th. The data reveals that the majority of this volume, amounting to $259.4 million, was executed on the Deribit exchange, while the remaining $49.8 million was traded on OKX. This significant block trade activity highlights institutional interest and large-scale positioning in the crypto derivatives market.

According to @GreeksLive, Bitcoin (BTC) is approaching a significant $14 billion options expiry on Deribit, which could heighten market volatility. The put-call ratio has climbed to 0.72, a level that typically signals bearish sentiment. However, the analysis suggests this rise is partly due to traders using "cash-secured puts" as a strategy to generate yield and accumulate BTC. Lin Chen of Deribit noted that nearly 20% of expiring call options are in-the-money, indicating many call buyers have profited this cycle. Crypto market maker Wintermute reports that recent market flows are neutral, with traders positioning for tight price action between $100,000 and $105,000 leading up to the expiry. The maximum pain price for this expiry is identified at $102,000, the level at which option buyers would incur the greatest losses.

According to @GreeksLive, reports that crypto exchange OKX is considering a U.S. initial public offering (IPO) triggered a significant, albeit temporary, 9.8% price spike in its native token, OKB, which jumped from approximately $50 to $55.11 before retracing. OKX's Chief Marketing Officer, Haider Rafique, confirmed the exchange would 'absolutely consider an IPO in the future,' with the U.S. as the preferred market, signaling growing confidence in its U.S. operations. This news aligns with a broader trend of crypto firms like Kraken and Bullish planning to go public. Concurrently, the institutional adoption of crypto is accelerating, as evidenced by derivatives exchange Deribit. Its Block Request-for-Quote (RFQ) tool for large institutional trades has processed over $23 billion in cumulative volume in less than four months since its March launch. Deribit CEO Luuk Strijers noted the system's success reflects 'strong institutional demand' for derivatives on assets like Bitcoin (BTC), Ether (ETH), and Solana (SOL), enhancing liquidity and execution for professional traders.
