Projected income on $10K

Projections assume the current yield and share price remain constant. Actual results will vary.

Total returns

100% reinvested · ex-date convention. Period returns use this fixed assumption, independent of chart settings. YTD and 1Y are cumulative period returns; 3Y, 5Y, and 10Y are annualized. The shared Since-start window is annualized only when it covers at least one year.

ARKB has lagged IBIT over the trailing twelve months, posting a -24.90% total return against -24.87%. Measured from Jan 2024 — the start of shared available history — IBIT has compounded at 22.02% a year versus 22.00% for ARKB. Figures are total returns: price change plus every distribution reinvested.

Total return with all distributions reinvested on the ex-dividend date (a modeling convention, not the cash-settlement date), split-adjusted, as of October 16, 2026. YTD and 1Y are cumulative period returns; 3Y, 5Y, and 10Y are annualized. The shared Since-start window is annualized only when it covers at least one year. “Since Jan 2024” measures every fund from January 11, 2024 — the start of shared available history — so all funds share one comparison window. Volatility is the annualized standard deviation of daily total returns over the past year. Sharpe and Sortino divide the annualized return in excess of the risk-free rate by, respectively, that volatility and the downside deviation (both over the past year) — higher is better. Max drawdown is the largest peak-to-trough total-return decline over the same window — shallower is better.

How the risk works

Read this before the income numbers below: the strategy mechanics on this page shape what those payouts can cost you.

  • Crypto volatility. ARKB and IBIT sit on top of crypto-asset prices, which routinely swing far more than equities. A single drawdown can exceed a year of distributions, so income projections deserve extra skepticism here.

What is the difference between IBIT and ARKB?

ARKB vs IBIT — at a glance

Generated October 17, 2026.

Overview

ARKB and IBIT are both spot bitcoin ETFs launched within a day of each other in January 2024, offering direct exposure to bitcoin's price movement without intermediaries or derivatives. Both charge low fees and neither distributes income, making them structurally similar but vastly different in size.

How they differ

The most significant difference is asset base. Neither fund pays distributions; both track bitcoin's spot price with similar beta readings (ARKB 1.8783, IBIT 1.8887), suggesting comparable responsiveness to bitcoin moves.

Who each is best for

ARKB: Fits investors who favor ARK's brand and research philosophy and are comfortable with a smaller, younger fund structure. Also suited for those with smaller positions or lower-friction access through certain broker platforms.

Key risks to know

  • Bitcoin price volatility. Both funds experience direct price swings tied to bitcoin's underlying volatility, which exceeds that of traditional equity and bond markets. The comparable betas (near 1.9) confirm this sensitivity.
  • Regulatory and custody risk. Bitcoin remains an unregulated asset class in many jurisdictions. Changes to U.S. or international policy, or loss of custody provider insurance or operational failure, could materially harm fund value.
  • Inception recency and track record. Both funds launched in January 2024 and have no extended performance history. Fee structures and fund closures of competing bitcoin products have varied; longevity cannot be assumed. If you value ARK's investment approach or seek a lower expense ratio, ARKB offers a 0.21% alternative. Both carry identical bitcoin exposure risk; your choice hinges on issuer preference, broker access, and position size. Past performance doesn't predict future results.
