Selling covered calls on IBIT: the premium, and the weekend gap
IBIT premiums look rich because bitcoin swings hard. The catch is the calendar. Bitcoin trades seven days a week, but the fund and its options only trade on market days. So your covered call can sit through a weekend you can't act on.
The short answer
Yes, you can sell Covered calls on IBIT. You own 100 shares of the fund, sell a call against them, and collect the premium.
The premium is bigger than on most funds because bitcoin moves a lot. But the shares carry all of bitcoin's downside. And because bitcoin trades on weekends while IBIT doesn't, the fund can open Monday far from Friday's close.
This isn't a recommendation to buy or sell IBIT.
What IBIT is
IBIT is the iShares Bitcoin Trust, run by BlackRock. It's a spot bitcoin ETF: the fund holds real bitcoin, and its share price tends to follow bitcoin's price. Spot bitcoin funds started trading in the US in January 2024. Options on IBIT have traded since late 2024.
What that means for selling calls:
- No dividend. Bitcoin pays nothing, so the fund has nothing to pass on. There's no ex-dividend date to cause early assignment.
- Big swings. The fund moves with bitcoin, which is far more volatile than a stock index. That's why the Implied volatility is high and the premium looks rich.
- No earnings. There's no company report. The big moves come from bitcoin itself, any day of the week.
- Busy options. IBIT options trade in large numbers, with Weekly options and tight spreads near the price. Check the chain before every trade.
Some funds sell calls on bitcoin funds for you. If you'd rather not manage it yourself, see a covered-call fund vs doing it yourself. For how spot funds work, see bitcoin ETFs explained.
The weekend problem
US stock markets close Friday afternoon and open Monday morning. Bitcoin keeps trading the whole time.
If bitcoin falls hard on Saturday, IBIT can't move until Monday. Then it opens at the new price, with a Gap on the chart. Your shares took the hit, and you had no chance to sell them or close the call over the weekend.
The same is true for long weekends and market holidays. My page on weekend gaps covers why this happens.
A covered call doesn't protect you from that gap. The premium is a small cushion. The shares fall almost as much as if you'd sold no call at all.
A weekend gap, worked out (an illustration, not a trade idea)
These numbers are for a made-up bitcoin fund, XYZ. They are not IBIT's prices.
Friday. You own 100 shares of XYZ at $60. That's $6,000. You sell a 30-day $66 call for $1.50. You collect $150.
The weekend. Bitcoin drops sharply on Saturday. Markets are closed. You can't do anything.
Monday. XYZ opens at $48. Your shares are down $1,200. The call is now nearly worthless. That's fine, since you sold it. But the $150 you collected barely dents a $1,200 drop.
Expiry. XYZ ends the month at $50. The call expires. You keep the shares.
| XYZ at expiry | Shares vs $60 | Premium | Total |
|---|---|---|---|
| $40 | −$2,000 | +$150 | −$1,850 |
| $50 | −$1,000 | +$150 | −$850 |
| $58.50 | −$150 | +$150 | $0 (break-even) |
| $60 | $0 | +$150 | +$150 |
| $66 | +$600 | +$150 | +$750 |
| $80 | +$600 (called away at $66) | +$150 | +$750 (capped) |
The worst case is bitcoin going far lower. The best case is capped at $750, however high it climbs. A plain holder at $80 would be up $2,000.
The month after: making it back the wrong way
Down $850, you want to make it back fast. The $60 call pays almost nothing now. So you sell a $54 call, below your $60 cost, for $1.20 ($120).
Then bitcoin rebounds over another weekend. XYZ opens Monday at $64 and is still there at expiry. Your shares are called away at $54.
| Path | Shares | Premiums | Total |
|---|---|---|---|
| You sold the $54 call; called away | −$600 | +$270 | −$330 locked in |
| You held the shares, no second call | +$400 | +$150 | +$550 |
The rebound came. The call below your cost sold your shares before it arrived. On a fund that gaps both ways, a strike below your cost is a bet that the gap only goes one way.
How sellers handle the gap risk
- Size it like bitcoin, not like an index fund. Ask what a 20% drop over one weekend does to your account. If that's too much, own fewer shares.
- Pick strikes you're happy to sell at. If you'd be upset to lose the shares at $66, don't sell the $66 call.
- Keep calls at or above your cost. That's the rule the second table breaks.
- Decide your exit on Friday. You can't act on Saturday, so make the plan before the weekend.
Selling calls on IBIT is one half of the wheel strategy. The other half, selling puts to get the shares, carries the same weekend risk. Check how much cash that takes in our cash-per-stock table.
In Canada, covered calls are widely allowed in a TFSA or RRSP, but options permissions differ by broker. Check your broker's help page for US-listed funds.
Questions
Can you sell covered calls on IBIT?
Yes. You need 100 shares of IBIT for each call, and options approval at your broker. Covered calls are usually the lowest approval level.
Why are IBIT option premiums so high?
Because bitcoin moves a lot, and the market prices that in. A high premium is the price of a big expected move, in both directions. It isn't extra money for nothing.
What happens to my IBIT covered call over the weekend?
Nothing trades until Monday. If bitcoin moves a lot on the weekend, IBIT opens at a new price and your shares take the move. You can't close the call or sell the shares until the market opens.
Does IBIT pay a dividend I can add to the premium?
No. The fund holds bitcoin, which pays nothing. Your only cash flow from a covered call is the premium itself.
