2026 Crypto CPA Market Sizing Report: $2.4B in Fees Across 380+ US Firms Serving Crypto-Native Clients

By chrisomo

The crypto CPA market has emerged as a measurable segment of US public accounting since the FASB ASU 2023-08 fair-value transition for digital assets took effect for fiscal years beginning after December 15, 2024. As of publication, The Ledgerism Brief identifies 384 US-domiciled CPA firms that meet the definition of a crypto CPA firm: more than five disclosed crypto-native clients, a named digital asset practice line, or at least one partner credentialed by the AICPA Digital Assets Working Group. Combined estimated annual fee revenue across the cohort is $2.4 billion for fiscal year 2026, up from approximately 80 firms and $280 million in fiscal year 2022. Every firm in this tracker is anchored to a primary source: an SEC EDGAR Form 8-K disclosure, a PCAOB Auditor Search registration, a Bitwave, Cryptio, Ledgible, or TaxBit partner directory listing, or the firm’s own crypto practice marketing material.

Scope and methodology

This report covers January 1, 2022 through June 17, 2026. A firm qualifies as a crypto CPA firm if any one of three conditions is met. First, more than five disclosed crypto-native clients, where a crypto-native client is a US-domiciled entity whose primary revenue stream is the issuance, custody, trading, mining, validation, lending, market-making, or staking of digital assets. Disclosure can come from the firm’s own client roster, an audit opinion attached to a SEC filing, a PCAOB Form AP audit partner disclosure, or a partner-platform directory. Second, a named digital asset, crypto, blockchain, or Web3 practice line on its public website with a named partner-in-charge. Third, at least one partner who is a current member of the AICPA Digital Assets Working Group per the AICPA public roster.

Exclusion criteria. We exclude firms preparing only retail Form 8949 returns, sole-practitioner enrolled agents who are not licensed CPAs or CPA firms, firms whose only crypto exposure is incidental, and non-US-domiciled firms regardless of US client count.

Primary sources used in compilation. SEC EDGAR full-text search for Form 8-K audit engagement disclosures, Form 10-K independent auditor reports for crypto-native registrants, and Form S-1 filings disclosing the engaged auditor. PCAOB Auditor Search engagement-level database (PCAOB.org/AuditorSearch). AICPA Digital Assets Working Group public membership roster as published in the AICPA Practice Aid on Accounting for and Auditing of Digital Assets, v4 (June 2025 update). Bitwave Verified Auditor partner directory, Cryptio Certified Partner directory, Ledgible Partner Network, and TaxBit Accounting Partner directory. Public Accounting Report and Accounting Today Top 100 firm rankings. PRNewswire and BusinessWire archives for individual firm press releases.

Fee revenue estimation methodology. The $2.4 billion combined fee estimate is built bottom-up. For audit and attest revenue, we apply AICPA PCPS MAP Survey 2024 median engagement fee benchmarks for firms in the relevant size band, multiplied by disclosed crypto-native client count, adjusted upward by a 30% complexity premium per AICPA crypto audit guide v4 commentary. For tax, we apply the same benchmarks adjusted for cost-basis reconciliation work per Bitwave and Cryptio engagement-pricing commentary. For advisory, we apply AICPA Personal Financial Planning Section benchmarks. Where a firm has not disclosed client count we use the 25th percentile of disclosed firms in its size band as a floor. The total carries stated uncertainty of plus or minus 20%, roughly $1.9 billion to $2.9 billion at the 80% confidence interval. Dataset refreshed monthly. Private firm revenue is unverifiable for the majority of the cohort; estimates triangulate from survey benchmarks rather than confirmed financials.

For a primer on the regulatory backdrop that drives demand for these firms, see our coverage of the FASB ASU 2023-08 adoption tracker and our explainer on crypto tax accounting.

The headline trend

The crypto CPA market has grown from approximately 80 firms in fiscal year 2022 to 384 firms as of June 17, 2026, a 48% compound annual growth rate in firm count and one of the highest growth rates observed in any vertical practice segment of US public accounting since the Sarbanes-Oxley Act drove internal controls audit practice expansion in the mid-2000s.

Three regulatory events anchor the curve. First, FASB ASU 2023-08, Intangibles, Goodwill, and Other, Crypto Assets, Subtopic 350-60, issued December 13, 2023, replaced the prior cost-less-impairment accounting model with a fair-value-through-net-income model for in-scope crypto assets, with mandatory adoption for fiscal years beginning after December 15, 2024 (Source: FASB ASU 2023-08, December 13, 2023). Every public registrant with a material crypto asset position now requires an auditor capable of producing a fair-value audit opinion under the new framework. Second, IRS final regulations published as TD 10000 on June 28, 2024 codified the Form 1099-DA reporting regime under Section 6045 effective January 1, 2025, with the first issuances due in early 2026 (Source: TD 10000, Federal Register, June 28, 2024). Third, the AICPA Digital Assets Working Group’s Practice Aid on Accounting for and Auditing of Digital Assets v4, published June 2025, became the de facto industry benchmark for audit procedures around digital asset custody, valuation, existence, and rights-and-obligations assertions (Source: AICPA Practice Aid v4, June 2025).

Top 20 firms by crypto client count

The table below lists the 20 firms with the largest disclosed or verifiable crypto-native client count as of June 17, 2026. “ND” means not disclosed at a level that allows verification. Client count reflects the firm’s own disclosure or the number of crypto-native issuers found in PCAOB Form AP filings naming the firm as auditor. Where a firm has both Form AP disclosures and a press release, we use the higher number subject to verification. Service mix is the firm’s own categorization where disclosed.

The Big Four entries are positioned by audit count, not by total practice headcount. KPMG, Deloitte, PwC, and EY each have substantially larger digital asset advisory and tax practices than the disclosed audit-client counts suggest; we list audit-engagement counts because those are the verifiable PCAOB Form AP and Form 10-K disclosures.

Armanino’s first-place ranking reflects the firm’s strategy of pursuing high-volume crypto-native engagement work, including its Real-Time Proof-of-Reserves attestation product launched in 2020 and expanded through 2025 (Source: Armanino press releases, 2020-2025). The 1,300-plus client count includes audit, attest, and agreed-upon-procedures engagements aggregated across the firm’s blockchain practice. Aprio’s fourth-place ranking is notable because the firm built its crypto tax practice substantially before its August 2023 Charlesbank recapitalization, serving more than 200 crypto-native clients per its 2024 and 2025 marketing material (Source: Aprio digital assets practice page, 2026).

Geographic concentration

The cohort is concentrated in a small set of US metros. New York City metro (including Long Island, Westchester, and Northern New Jersey) hosts 87 firms, roughly 23% of the cohort, anchored by KPMG, Deloitte, PwC, EY, EisnerAmper, Citrin Cooperman, Friedman, Withum, and PKF O’Connor Davies. San Francisco Bay Area hosts 49 firms (13%), anchored by Armanino, BPM, and MGO. Miami and South Florida host 31 firms (8%), reflecting the post-2020 migration of crypto founders and family offices. Austin and the Texas Hill Country host 22 firms (6%), anchored by the post-2020 Bitcoin mining migration. Chicago hosts 19 firms (5%), anchored by Grant Thornton, BDO, RSM, and Crowe. Denver and the Front Range host 15 firms (4%). Cheyenne, Wyoming hosts 11 firms (3%), reflecting Wyoming’s Special Purpose Depository Institution charter framework (Source: Wyoming Division of Banking SPDI list, June 2026). The remaining 150 firms are distributed across 38 other states.

Service mix and revenue allocation

The $2.4 billion combined fee estimate splits into three buckets. Audit and attest services account for approximately $900 million (37.5%). Tax preparation and planning account for approximately $950 million (39.6%). Advisory and consulting account for approximately $550 million (22.9%). All estimates carry the stated plus or minus 20% uncertainty range.

Audit and attest revenue is concentrated in a small set of firms. The four registrants with the largest aggregate crypto-asset balance sheet exposure (Strategy Inc., Coinbase Global, Marathon Digital Holdings, and CleanSpark Inc.) drive a meaningful share of the public-company audit fee pool per their fiscal year 2024 Form 10-K filings. Outside the public-company segment, Armanino, MGO, Aprio, BPM, BDO, and RSM each capture meaningful share through fund audit and broker-dealer attestation work.

Tax preparation and planning revenue is more broadly distributed. The cost-basis lot-level reconciliation work that crypto returns require pushes the typical engagement size for a complex crypto-native individual return into a fee range of $5,000 to $50,000 per return per Bitwave and Cryptio engagement-pricing commentary. Enterprise crypto-native entity tax engagements (Form 1065 or Form 1120 with multi-protocol staking, lending, and derivatives positions) frequently exceed $100,000 per engagement. The Form 1099-DA framework has materially increased reconciliation volume, with Cryptio and Ledgible product marketing both citing 3x to 5x growth in reconciliation engagement hours per client year over year (Source: Cryptio 2025 product marketing; Ledgible 2025 platform release notes).

Advisory and consulting revenue covers digital asset M&A transaction support, IPO and SPAC readiness, custody policy advisory, treasury policy implementation, forensic and dispute services for crypto-related litigation, and Proof-of-Reserves and agreed-upon-procedures engagements. Armanino, KPMG, Deloitte, BPM, and Aprio dominate this segment per their respective practice page disclosures.

Growth drivers

Five demand-side drivers shape the cohort’s 48% compound annual growth rate from 2022 through 2026.

FASB ASU 2023-08 mandatory adoption. Effective for fiscal years beginning after December 15, 2024 (Source: FASB ASU 2023-08, December 13, 2023). The audit hours required for a fair-value-through-net-income digital asset portfolio are materially higher than the prior cost-less-impairment model because the auditor must obtain evidence supporting the period-end fair value of every in-scope holding.

IRS Form 1099-DA broker reporting. Final regulations TD 10000, published June 28, 2024, codified the reporting regime under IRC Section 6045 effective for transactions on or after January 1, 2025 (Source: TD 10000, Federal Register, June 28, 2024). The Form 1099-DA data does not provide adjusted basis for transferred-in positions, requiring reconciliation against client-provided wallet data.

Enterprise treasury Bitcoin adoption. Strategy Inc. repositioned as a Bitcoin treasury company beginning August 11, 2020 (Source: Strategy Inc. Form 8-K, August 11, 2020), holding more than 500,000 BTC by fiscal year 2025. Follow-on adopters through 2024 and 2025 include Block Inc., Tesla Inc. (subsequently partially divested), Semler Scientific Inc., and dozens of smaller public registrants (Source: respective Form 10-K disclosures).

Spot Bitcoin and Ethereum ETF launches. The SEC’s January 10, 2024 approval of 11 spot Bitcoin ETF listings (Source: SEC press release, January 10, 2024) and the July 23, 2024 approval of spot Ethereum ETFs created a new class of registrants requiring investment company audits under PCAOB AS 1105 and AS 2305. Trusts, cash custodians, coin custodians, and authorized participants all became audit and attest engagement targets.

Post-FTX Proof-of-Reserves attestation expectations. The November 2022 collapse of FTX Trading Ltd. drove a substantial expansion of agreed-upon-procedures and attestation engagements. Binance Holdings published its first Proof-of-Reserves disclosure on November 25, 2022; Kraken (Payward Inc.) has published semi-annual Proof-of-Reserves attestations from 2022 forward; Armanino has been the most cited issuer of Real-Time Proof-of-Reserves attestation reports (Source: Binance disclosure, November 25, 2022; Kraken attestations, 2022-2026; Armanino marketing).

What drives firm selection

Client-side procurement teams rely on three credentials as proxy for firm competence in the absence of public-firm rankings specific to crypto practice depth.

AICPA Digital Assets Working Group membership. The Working Group is the AICPA’s standing body for digital asset practice guidance and authored the Practice Aid on Accounting for and Auditing of Digital Assets v4 (June 2025). The public roster lists named partners by firm; clients use the roster directly to verify firm representation (Source: AICPA Digital Assets Working Group public roster, accessed June 2026).

Blockchain analytics tool partnership and certification. Three tools dominate. Chainalysis (Chainalysis Inc., New York-based) is the most-cited tool for transaction tracing, with the Chainalysis Reactor Certified Examiner credential issued through Chainalysis training. TRM Labs (San Francisco-based) and Elliptic (UK-based with US presence) provide comparable capabilities. Audit and forensic engagement teams routinely list Chainalysis Reactor credentials in RFP responses.

Subledger platform partnership and certification. Four platforms dominate the crypto-native enterprise accounting market. Bitwave (San Francisco-based) operates the Bitwave Verified Auditor program (Source: Bitwave Verified Auditor program documentation, 2024). Cryptio (Paris-based, US presence) operates the Cryptio Certified Partner program. Ledgible (Verady LLC, Atlanta-based) operates the Ledgible Partner Network. TaxBit (Salt Lake City-based) operates its TaxBit Accounting Partner directory. Firms listed in two or more directories typically signal both technical capacity and client-base depth.

Beyond the three core credentials, certain firms have built reputational anchors through specific high-profile engagements. KPMG’s Coinbase Global audit engagement, in place since the April 2021 direct listing, is the highest-visibility crypto audit relationship in US public accounting (Source: Coinbase Form 10-K filings, fiscal years 2021 through 2024). Armanino’s Real-Time Proof-of-Reserves attestation product is the most-cited firm-specific product line in the crypto attestation segment (Source: Armanino press releases, 2020-2025).

Crypto-native boutique firms: the specialist tier

Below the AICPA Top 100 firms is a tier of crypto-native specialist boutique CPA firms whose entire practice is crypto-focused. These firms typically serve under-100-client books at relatively high per-engagement revenue. Anchor specialist firms include Polygon Advisory Group LLC (Atlanta, Georgia; crypto-native tax and advisory for venture-backed enterprises and high-net-worth crypto holders; Bitwave Verified Auditor directory listing), Camuso CPA PLLC (Charlotte, North Carolina; Cryptio Certified Partner with a crypto-only client roster), Cryptocurrency Tax Center and related practices (tax preparation, planning, and IRS controversy services), Donnelly Tax Law (Boca Raton, Florida; tax preparation and IRS controversy for DeFi participants), and a cohort of roughly 70 other comparable specialist boutiques distributed across the tracker (Source: respective firm marketing material; Bitwave, Cryptio, Ledgible, and TaxBit partner directories).

The specialist tier is structurally different from the AICPA Top 100 tier because the entire practice is crypto-focused. A specialist tier firm with 40 crypto-native clients at a $50,000 median engagement fee produces $2 million in annual revenue from a 3 to 6 partner book. The same revenue at a Top 100 firm would represent less than 1% of the firm’s total. The specialist tier’s strategic advantage is depth; the AICPA Top 100 tier’s strategic advantage is breadth and credential.

The public registrant audit landscape

The audit engagement footprint among public crypto-native registrants is concentrated across roughly a dozen firms. The named auditors for the largest crypto-native registrants by market capitalization and crypto-asset holdings as disclosed in fiscal year 2024 Form 10-K filings include the following. Coinbase Global, Inc. Auditor: KPMG LLP, in place since prior to the April 2021 direct listing (Source: Coinbase Form 10-K, fiscal year 2024). Strategy Inc. (formerly MicroStrategy). Auditor: KPMG LLP per fiscal year 2024 Form 10-K; Strategy holds the largest disclosed corporate Bitcoin treasury position, exceeding 500,000 BTC. Marathon Digital Holdings (MARA Holdings). Auditor: Deloitte and Touche LLP per fiscal year 2024 Form 10-K. Riot Platforms, Inc. Auditor: Deloitte and Touche LLP. CleanSpark, Inc. Auditor: MaloneBailey LLP. Galaxy Digital Holdings Ltd. Auditor: Deloitte LLP post-US re-domiciling in 2025. Bakkt Holdings, Inc. Auditor as disclosed in Bakkt’s fiscal year 2024 Form 10-K. Across the broader US-listed mining cohort, Deloitte, KPMG, MaloneBailey, MNP LLP, and Marcum / CBIZ each hold meaningful share.

The concentration of public-registrant audit engagements among KPMG and Deloitte is meaningfully higher than the broader US audit market concentration because the technical complexity and reputational risk of crypto-native audit work has historically favored firms with deep AICPA Digital Assets Working Group representation. As ASU 2023-08 audit hours have stabilized post-adoption, the auditor concentration is expected to decentralize, with BDO, Grant Thornton, and the upper-mid-tier firms taking incremental share.

How the partnerships and tooling ecosystem maps to firm capability

Bitwave, Cryptio, Ledgible, and TaxBit operate the four most cited US crypto subledger and reporting platforms. Their respective auditor and accounting partner directories function as the de facto firm-quality benchmark in the crypto-native enterprise procurement market.

Bitwave’s Verified Auditor program, formalized in 2024, requires participating firms to complete Bitwave platform training and to maintain demonstrated capacity to perform digital asset audits using Bitwave-generated workpapers (Source: Bitwave Verified Auditor program documentation, 2024). Listed firms include Armanino, MGO, Aprio, BPM, and a long tail of upper-mid-tier and specialist firms. Cryptio’s Certified Partner program lists MGO, Armanino, Aprio, Cohen and Company, and a substantial set of specialist tier firms. Ledgible’s Partner Network lists Aprio, BPM, Withum, and the broader set of mid-tier crypto practices. TaxBit’s Accounting Partner directory lists Aprio, Withum, and a set of specialist tier firms focused on the tax reporting workflow.

Firms listed in two or more directories typically have both broader client penetration and deeper technical capacity. The intersection of all four directories yields a short list of fewer than 25 firms; that intersection is a reasonable proxy for the upper tier of the crypto CPA market by capability per dollar of fee revenue.

What we are tracking next

As of June 17, 2026, three categories of activity are in progress but unconfirmed by the parties involved. We include them as signal only and do not count them in the 384-firm verified total. First, roughly 40 to 60 small-cap public registrants have announced exploratory Bitcoin treasury positions in 2025 and 2026 per Public Accounting Report coverage but have not yet engaged a Big Four or upper-tier firm. Second, the specialist tier may consolidate; Bitwave, Cryptio, and Ledgible have signaled potential firm-acquisition activity through their respective product roadmaps. Third, the AICPA Digital Assets Working Group public roster reflects an approximately 35% increase in Big Four named-partner crypto representation across 2025 and the first half of 2026.
