Brendan Blumer Net Worth: From a $4 Billion ICO to Becoming a Billionaire on His Own Terms

Brendan Blumer’s career contains one of crypto’s strangest contradictions: a company that raised the largest ICO in history, settled fraud allegations with the SEC, burned through $150 million on a social media platform that quietly became a dead NFT marketplace, lost its founder over $70 million on a single bank investment — and yet, in August 2025, made him an actual billionaire anyway.

Blumer is the co-founder and CEO of Block.one, the company behind the EOS.IO blockchain. As of 2026, his net worth is estimated at approximately $750 million to over $1 billion, depending on how Bullish — the crypto exchange he also founded — is valued following its 2025 public listing.

This is the complete story of how he built it, lost a significant chunk of it, and then built it again through an entirely different company.

The Teenage Entrepreneur: Gamecliff to Hong Kong

Brendan Blumer was born on August 8, 1986, and raised in Cedar Rapids, Iowa, attending Linn-Mar High School. At just 15 years old, while still in high school, he built Gamecliff — a website selling virtual in-game items like weapons, armour, and characters for massively multiplayer online games including EverQuest and World of Warcraft.

In 2005, immediately after graduating high school, Blumer sold Gamecliff to IGE and relocated to Hong Kong to continue running its operations — an unusually early and decisive move into the virtual goods economy, years before most people had heard the term.

He continued building in this space, founding The Accounts Network in 2007, which reached $1 million in monthly revenue selling MMORPG avatars and in-game assets. In 2010, alongside Kokuei Yuan — a business partner who would remain central to Blumer’s career for the next two decades — he launched Okay.com, a real estate data-sharing platform for Asia-Pacific property brokers.

This pattern — identifying overlooked digital or data marketplaces and building infrastructure around them — became the throughline of Blumer’s career long before blockchain entered the picture.

Block.one and the EOS ICO: Crypto’s Most Controversial Fundraise

In 2016, Blumer co-founded Block.one alongside Dan Larimer, setting out to build EOS.IO — a blockchain platform explicitly positioned as a faster, more scalable alternative to Ethereum, sometimes nicknamed within the community as “Ethereum on Steroids.” To understand the broader blockchain landscape EOS was competing within, read our what is Bitcoin guide.

In May 2017, Block.one launched the EOS Initial Coin Offering. By the time it concluded in June 2018, the sale had raised approximately $4.1 billion — the largest ICO in cryptocurrency history at that time, and a figure that remains among the largest token sales ever conducted. The offering was deliberately structured to exclude purchasers from the US and China, a decision later scrutinised heavily by regulators.

In February 2018, Forbes listed Blumer among the “richest people in cryptocurrency” — recognition that arrived even before the ICO had fully concluded, based on the scale of capital Block.one was raising and Blumer’s substantial personal EOS holdings.

The SEC Settlement and Investor Lawsuits

The EOS ICO’s massive success quickly attracted equally massive regulatory and legal scrutiny.

In September 2019, Block.one settled with the US Securities and Exchange Commission for $24 million, after the SEC alleged the company had conducted an unregistered securities sale. SEC co-Director of Enforcement Steven Peikin stated that Block.one had failed to provide investors with the disclosures typically required in a securities offering. Block.one settled without admitting or denying the SEC’s findings — a standard structure for this type of regulatory resolution.

The regulatory settlement was followed by private investor litigation. A class action lawsuit, filed in the Southern District of New York by the Crypto Assets Opportunity Fund and investor Johnny Hong, named Blumer personally as a defendant alongside Block.one, Dan Larimer, former Chief Strategy Officer Brock Pierce, and former partner Ian Grigg. The complaint characterised the EOS offering as arising from “a fraudulent scheme, fueled by a global frenzy over cryptocurrencies,” alleging the company artificially inflated the EOS token price and failed to decentralise the network as promised to investors.

This litigation resulted in a $27.5 million class-action settlement in 2021. However, that settlement was later blocked by a federal judge in 2023, with District Judge Lewis Kaplan questioning whether the token sales — conducted while Block.one was based in Hong Kong — even fell under US jurisdiction as “domestic transactions.”

It is important to note: Blumer has never been personally charged with fraud in a criminal sense, and Block.one resolved both the SEC action and investor litigation without formal admissions of wrongdoing. However, his executive role placed him at the centre of allegations that one legal complaint went so far as to call “the biggest of all crypto frauds” — a characterisation Blumer and Block.one have disputed.

Voice: The $150 Million Social Media Platform That Failed

Following the ICO’s massive cash haul, Block.one needed to demonstrate genuine utility for the EOS ecosystem — and Blumer’s answer was an ambitious social media platform called Voice.

Announced in June 2019 and launched in beta in August 2020, Voice was built on the EOSIO protocol and marketed as a transparent, blockchain-based alternative to mainstream social media — sometimes informally described as a “decentralised Facebook.”

Block.one reportedly invested approximately $150 million into building Voice, separately spending an additional $30 million simply to acquire the Voice.com domain name. Despite this substantial investment, the platform never achieved meaningful user adoption or engagement at scale.

By the time references to Voice were quietly removed from Block.one’s own website, the domain had been repurposed into an NFT marketplace — one that, according to industry reporting, has since maintained negligible trading volume. The $180 million combined investment in Voice and its domain stands as one of the most expensive failed product launches in crypto history.

The Silvergate Bank Disaster: A $70 Million Personal Loss

Perhaps the most dramatic single chapter in Blumer’s financial history involves Silvergate Capital — a bank that had built a reputation as one of the few crypto-friendly banking institutions in the United States.

Beginning around November 16, 2022, Blumer — both personally and through Block.one — accumulated a stake in Silvergate, eventually controlling approximately 9.27% of the bank’s stock, having spent over $90 million on the position. Block.one owned roughly 7.5% of this stake, with Blumer personally holding the remaining 1.7%, though he was listed as the beneficial owner of the full position for regulatory purposes.

The timing could not have been worse. Silvergate’s largest account holders included FTX and Alameda Research — both of which collapsed into bankruptcy just five days before Blumer’s investment began. As the fallout from the FTX collapse spread through the crypto banking sector, Silvergate’s stock collapsed by more than 80%.

Blumer personally lost an estimated $74 million on the position. In the press release announcing the original investment, Blumer had been described as a “passive investor” — a characterisation that, in hindsight, did little to soften the scale of the loss once Silvergate’s collapse fully unfolded. For more on how the FTX collapse triggered this broader banking contagion, read our FTX collapse explained guide.

Bullish: The Comeback That Made Him an Actual Billionaire

Despite Voice’s failure and the Silvergate loss, Blumer’s most financially significant venture arrived through a different company entirely.

In 2020, Blumer co-founded Bullish alongside his longtime business partner Kokuei Yuan — a cryptocurrency exchange built using technology originally developed for EOS, but positioned as an entirely separate, institutionally focused trading platform rather than another EOS ecosystem product.

Bullish proceeded methodically over several years, building out its exchange infrastructure and institutional client base away from the intense public scrutiny that had surrounded Block.one and EOS. The strategy paid off decisively: Bullish’s initial public offering in August 2025 made Blumer a billionaire — the first time his net worth crossed that threshold based on a single, clearly verifiable, publicly traded asset.

Separately, Block.one’s post-ICO capital was directed into a range of strategic investments beyond Silvergate, including significant Bitcoin accumulation, leading CoinDCX’s Series B funding round, and stakes in companies including Northern Data and CipherTrace. Block.one was also involved in Bullish’s 2023 acquisition of CoinDesk, the cryptocurrency news outlet — adding media ownership to Blumer’s expanding portfolio of crypto-adjacent assets.

Why Net Worth Estimates Vary So Significantly

Brendan Blumer’s net worth is genuinely difficult to pin to a single figure for several specific reasons.

Bullish’s stock price directly drives the estimate. As a newly public company, Bullish’s valuation — and therefore Blumer’s stake — fluctuates with normal stock market volatility, unlike a fixed, privately-held asset.

Block.one’s remaining holdings are not fully disclosed. The company’s Bitcoin holdings, its stakes in companies like Northern Data and CipherTrace, and its exact current EOS token holdings are not comprehensively public, making a complete asset-by-asset calculation impossible from outside sources.

Past losses complicate historical comparisons. The Silvergate loss alone demonstrates how dramatically Blumer’s net worth can shift within a single year based on a concentrated bet — a pattern that likely continues to apply to his current holdings to some degree.

FAQ

What is Brendan Blumer’s net worth in 2026?

Estimates place his net worth between $750 million and over $1 billion, with the wide range reflecting Bullish’s fluctuating public stock valuation following its August 2025 IPO, alongside undisclosed details of Block.one’s remaining asset holdings.

Did Brendan Blumer commit fraud with the EOS ICO?

Blumer has not been personally charged with fraud in a criminal proceeding. Block.one settled with the SEC for $24 million in 2019 over unregistered securities allegations, and separately faced a $27.5 million investor class-action settlement (later blocked by a federal judge), both without formal admissions of wrongdoing.

What happened to Voice, Block.one’s social media platform?

Voice, launched in beta in 2020 after a reported $150 million investment plus $30 million for its domain name, failed to gain meaningful user adoption. References to the platform were later removed from Block.one’s website, and the Voice.com domain was repurposed into an NFT marketplace with reportedly negligible trading activity.

How much money did Brendan Blumer lose on Silvergate Bank?

Blumer personally lost an estimated $74 million when Silvergate Capital’s stock collapsed by more than 80% following the FTX and Alameda Research bankruptcies in November 2022 — both of which had been major Silvergate account holders.

How did Brendan Blumer become a billionaire?

Bullish, the cryptocurrency exchange Blumer co-founded in 2020 with Kokuei Yuan, completed its initial public offering in August 2025. The IPO’s valuation pushed Blumer’s net worth above $1 billion for the first time, based on a publicly verifiable, traded asset rather than private company estimates.

Is Brendan Blumer still involved with EOS?

Block.one, the company Blumer continues to lead as CEO, remains associated with the EOS ecosystem, though the company’s strategic focus has expanded significantly into other investments, including Bitcoin holdings, venture stakes, and the Bullish exchange, rather than EOS-specific development being its sole focus.

Final Word

Brendan Blumer’s financial story resists a simple narrative of either triumph or failure — it genuinely contains both in significant measure.

The EOS ICO made him one of crypto’s most recognised early billionaires-in-waiting, then immediately entangled him in years of regulatory settlements and investor litigation. Voice consumed $150 million and produced essentially nothing of lasting value. The Silvergate investment cost him tens of millions personally during one of crypto’s most damaging contagion events. And yet, through Bullish — a separate venture built quietly while EOS-related controversies played out — he ultimately became an actual, publicly verifiable billionaire in 2025.

That trajectory offers a genuinely useful lesson distinct from most crypto billionaire stories: sustained entrepreneurial activity across multiple ventures, even when several fail expensively and publicly, can still eventually produce a successful outcome — provided the underlying business model of the surviving venture is genuinely sound.
