Options on spot Bitcoin ETPs

Tomáš sees an IBIT option in his trading app and imagines a right to buy bitcoin. But there is another layer between him and the coin: a share of an exchange-traded product, or ETP. That share is the option’s underlying asset. In September 2024, the U.S. Securities and Exchange Commission, SEC, approved rules for IBIT options with American-style exercise and physical settlement. Physical means delivery of ETP shares, not BTC to a wallet. A standard contract usually represents 100 shares. Adjusted contracts or individually specified terms can differ, so identifying the underlying and the deliverable quantity comes before any calculation. [1] [2]

In our own example, Tomáš buys a call with a strike of 50 USD, a premium of 3 USD per share and a multiplier of 100. The right costs him 300 USD, rather than the single quoted figure on the screen. The multiplier converts the quote to the number of shares covered. The premium buys the opportunity to purchase at the agreed price during the option’s life; it is not a down payment on shares. Exercising would require another 5,000 USD for the purchase. He can also sell the option before expiry if he finds a counterparty, but the sale price cannot be guaranteed in advance. [2] [3]

Take the same example at expiration, the end of the option’s life. If the share price is 55 USD, the right to buy at the agreed price has an intrinsic value of 500 USD for the whole contract. That is the value of the advantage over buying in the market. Deducting the premium leaves a profit of 200 USD before costs. The break-even price, where the advantage just covers the premium, is 53 USD per share. At a share price of 50 USD or less, the call has no intrinsic value in this expiration model; letting it expire unused loses the 300 USD premium. That is the risk of the purchased option alone before costs, not a ceiling on losses from shares subsequently bought through exercise. [3]

A put works in the other direction. Our example has a strike of 50 USD, a premium of 2 USD per share and a multiplier of 100. If the share price is 45 USD at expiration, the contract’s intrinsic value is 500 USD and profit after the premium is 300 USD before costs. This right can help protect shares already held against a decline, but protection costs money and expires. Exercising this physically settled put means delivering 100 relevant shares and receiving 5,000 USD, not automatically receiving only the cash difference. Anyone without the shares must first understand their broker’s rules and available arrangements. [4]

American-style exercise lets the holder exercise before expiration. On the other side, a writer may be assigned an obligation to deliver or buy shares. OCC, the U.S. clearing institution that handles option settlement, specifies T+1 delivery for weekly equity and ETF options: the next business day after exercise. Tomáš needs to know his broker’s instruction deadline and so-called automatic exercise procedures; doing nothing does not always mean the option simply disappears. Exercising a call leaves him holding purchased shares with subsequent share-price risk. Selling the option and exercising it are different ways of ending the position. [2] [4]

Before expiry a call’s price is more than the difference between the share price and strike. It also reflects the chance of a favorable move during the remaining time. Passing time generally reduces that component if other conditions stay unchanged. Implied volatility is the expected degree of fluctuation inferred from the option’s market price. A decline in it can reduce the call’s value enough to outweigh a rising share price. Tomáš can therefore predict the direction correctly and still sell at a loss. The 53 USD expiration break-even from our example is not a universal threshold for a profitable sale before expiry. [3]

If Tomáš writes a call instead, he receives a premium and takes on an obligation. Delivering a standard contract requires 100 of the relevant shares. BTC in his own wallet does not automatically substitute for them. Holding those shares alongside a written call is called a covered call: delivery is covered, but the shares can still fall, and assignment gives up their rise above the strike to the buyer. The premium is not risk-free income. For an uncovered call without matching shares or other protection, losses from a sharp rise in the underlying have no theoretical upper bound. A writer’s risk must not be confused with the buyer’s limited premium at risk. [4] [6] [7]

Technical terms evolve. On May 19, 2026, MIAX announced an increase in the position and exercise limits for IBIT options to 1,000,000 contracts. That is a dated fact for the named venue and product, not a universal limit for every bitcoin ETP or an entitlement to open such a large customer position. A broker can impose stricter restrictions. The historical 25,000 contracts in the original approval cannot be presented as today’s rule without checking either. For an actual option, verify the current specifications, date, deliverable share quantity, exercise method and account terms. Only then does calculating a possible outcome have a clear meaning.
