The Largest Private Crypto and Blockchain Companies in 2026

Crypto has produced some of the most dramatic rises and falls in startup history. Companies that were worth tens of billions in 2021 collapsed in 2022, while others survived the downturn and are now larger than ever, helped by clearer regulation, the growth of stablecoins and a new wave of institutional adoption. This guide ranks the largest private crypto and blockchain companies in our database by sourced valuation, explains the main business models in the industry, and looks at the risks that still make crypto valuations volatile.

Every valuation links to a full profile with its source and date. We cover only private companies; publicly traded crypto companies such as Coinbase, Circle, Galaxy and Bullish are mentioned for context.

The ranking

We also profile Kalshi, a US prediction market valued at US$22 billion. Kalshi is regulated by the Commodity Futures Trading Commission and settles in US dollars rather than crypto, so we don't rank it as a crypto company, but it competes directly with Polymarket.

The main types of private crypto companies

Payments and stablecoin infrastructure

Ripple, valued at US$50 billion in a March 2026 share buyback, is the largest private crypto company in our database. It provides cross-border payment services for financial institutions, holds large amounts of the XRP token, and has expanded into stablecoins with its RLUSD dollar token, custody and prime brokerage through acquisitions. Its settlement with the US Securities and Exchange Commission over XRP removed a major legal overhang. Stablecoins, digital tokens pegged to currencies like the dollar, have become crypto's most practical application, used for trading, remittances and business payments. Tether, the largest stablecoin issuer, is privately held and was reported in 2025 to be exploring a fundraise at a valuation of about US$500 billion; we don't yet profile it.

Custody and security

Institutions need secure ways to hold and move digital assets. Fireblocks supplies wallet and custody infrastructure to banks, fintechs and exchanges and was valued at US$8 billion in 2022. Ledger, the French maker of hardware wallets, sells devices that store users' private keys offline and has an enterprise business. Other private players include Anchorage Digital, a US federally chartered crypto bank, and BitGo.

Prediction markets

Polymarket lets users trade on the outcomes of events using stablecoins. After settling with US regulators in 2022, it acquired a licensed exchange to return to the US, and in 2025 Intercontinental Exchange, owner of the New York Stock Exchange, agreed to invest up to US$2 billion at a US$9 billion post-money valuation. Prediction markets became one of the fastest-growing areas of crypto and fintech in 2025 and 2026.

Exchanges and brokers

Bitpanda, based in Vienna, lets European retail investors buy crypto, stocks, ETFs and metals, and provides white-label services to banks. Canada's Shakepay offers a simple app for buying bitcoin and ether. Large private exchanges outside our database include Kraken, OKX and Bybit. Coinbase, the largest US exchange, is public.

NFTs and Web3 consumer apps

Dapper Labs, the Vancouver company behind CryptoKitties, NBA Top Shot and the Flow blockchain, reached a reported US$7.6 billion valuation at the 2021 NFT peak. NFT trading volumes fell sharply afterwards, and Dapper has cut staff and refocused. Its peak valuation is a reminder of how far some crypto valuations have fallen since 2021.

How crypto valuations changed

Crypto company valuations track the market cycle closely. In 2021, rising token prices and trading volumes pushed exchanges, wallets and NFT companies to record valuations. In 2022, the collapse of TerraUSD, Celsius, Three Arrows Capital and FTX wiped out hundreds of billions of dollars of value and destroyed trust. Venture funding for crypto fell sharply, and many companies raised at lower valuations or shut down. From 2024, the approval of spot bitcoin ETFs in the US, more favourable US policy, the GENIUS Act regulating stablecoins and institutional adoption led to a recovery. Companies that survived with strong businesses, such as Ripple, have since raised at higher valuations, while some 2021-era marks, such as Dapper Labs' and Fireblocks', haven't been updated publicly.

What drives crypto company value

• Token holdings: some companies hold large amounts of crypto, so their value rises and falls with token prices. Ripple's XRP holdings are an example.
• Trading volumes: exchanges and brokers earn more when markets are active.
• Recurring infrastructure revenue: custody, payments and software companies earn fees that are more stable than trading revenue.
• Regulatory licences: licences in major markets are hard to obtain and create moats.
• Institutional partnerships: deals with banks and exchanges, such as ICE's investment in Polymarket, signal legitimacy and open new revenue.

Regulation

Regulation is the biggest single factor for crypto companies. In the United States, the SEC's approach shifted from aggressive enforcement to a more accommodating stance in 2025, and Congress passed the GENIUS Act to create a federal framework for stablecoins. In Europe, the Markets in Crypto-Assets regulation (MiCA) created a licensing regime across the EU, benefiting licensed players such as Bitpanda. Other countries, including the UK, Singapore, Hong Kong and the UAE, have built their own frameworks. Companies that invest early in compliance often gain an advantage when rules tighten, but policy can change quickly with elections and market events.

Risks for investors and users

• Volatility: token prices can fall by more than half in months, hitting revenue and valuations.
• Security: hacks and thefts remain common, and a major breach can destroy a company's reputation.
• Counterparty risk: customers of failed exchanges have lost funds; check how assets are held and segregated.
• Regulatory change: new rules or enforcement can close business lines.
• Stale valuations: many private crypto valuations date from 2021 and may be far above current value.

Could more crypto companies go public?

Circle's successful IPO in 2025 and listings by other crypto firms showed public market appetite for crypto businesses with real revenue. Ripple, Kraken, Fireblocks and others are frequently mentioned as IPO candidates, though some, like Ripple, have said they have no immediate plans to list. Our guide to investing in pre-IPO companies explains how investors can gain exposure before a listing and the risks involved.

Using this list

Business development teams at banks and fintechs can identify infrastructure partners. Job seekers can compare funding and stability. Investors can track which companies have updated valuations since 2021. Researchers can start from the profiles and follow the sources; our guide to researching a private company explains how.

Stablecoins as the industry's growth engine

Stablecoins have grown into a market worth hundreds of billions of dollars, used for trading, cross-border payments, remittances and savings in countries with unstable currencies. Issuers earn interest on the reserves backing their tokens, usually held in short-term US government debt, which can be extremely profitable when interest rates are high. Payment companies, banks and fintechs are integrating stablecoins for faster settlement, and infrastructure providers such as Fireblocks benefit from the activity. Circle's listing in 2025 gave public investors a pure-play stablecoin company, and private players are positioning for the same opportunity.

Institutional adoption

Since US spot bitcoin ETFs launched in 2024, large asset managers, pension funds and corporate treasuries have gained easier access to crypto. Banks have begun offering custody and trading to clients, and traditional exchange operators have invested in crypto businesses, as ICE did with Polymarket. Institutional participation tends to favour regulated, well-capitalised companies with strong security records, which is a tailwind for infrastructure providers rather than speculative consumer apps.

Crypto companies in Canada and Europe

Outside the US, crypto companies operate under a patchwork of national and regional rules. Canada requires crypto trading platforms to register with securities regulators, which Shakepay and others have done. In Europe, MiCA licences let firms like Bitpanda serve customers across the EU from one authorisation, encouraging consolidation around licensed players.
