BNP Paribas Launches Crypto ETNs, First Bitcoin Mortgage, Polymarket Valued at $2 Billion
📋 En bref (TL;DR)
- BNP Paribas launches 6 crypto ETNs: starting March 30, 2026, French retail clients can invest in Bitcoin and Ethereum through their regular brokerage accounts
- Bitcoin-backed mortgages in the US: Coinbase and Better launch the first Fannie Mae-compliant home loan collateralized by Bitcoin or USDC
- No sale, no tax: the crypto mortgage lets BTC holders use their coins as collateral without triggering a taxable event
- Polymarket valued at $2 billion: ICE (NYSE parent company) invests an additional $600 million in the prediction markets platform
- California vs insider trading: Governor Newsom bans state officials from betting on prediction markets using privileged information
- Massive institutional adoption: these three announcements illustrate the accelerating integration of crypto into traditional finance
The week of March 28, 2026 marks a turning point in institutional crypto adoption. In France, BNP Paribas is opening access to Bitcoin and Ethereum through ETNs for its retail clients. In the United States, Coinbase is making the first Bitcoin-backed mortgage compliant with Fannie Mae standards a reality. And the NYSE’s parent company is investing $2 billion in Polymarket, the prediction market platform shaking up finance.
Three strong signals confirming a trend: crypto is no longer a fringe asset — it’s being woven into everyday financial products.
BNP Paribas opens crypto to French retail investors
Starting March 30, 2026, BNP Paribas and Hello bank! clients will be able to invest in six ETNs (Exchange Traded Notes) tracking Bitcoin and Ethereum. These products will be accessible directly from a standard brokerage account, with no need for a crypto wallet or specialized platform.
This is a first for Europe’s largest bank by assets. BNP Paribas had already explored tokenization on Ethereum in February 2026, but this time it’s targeting individual savers directly.
How it works
ETNs are exchange-listed financial instruments that replicate the performance of an underlying asset — in this case, Bitcoin or Ethereum. The investor does not directly hold the cryptocurrencies: they purchase a financial security issued by a recognized issuer, within the MiFID II regulatory framework.
The 6 ETNs will be available to retail clients, business accounts, private banking, and Hello bank! customers. BNP Paribas plans a gradual rollout to its Wealth Management clients internationally.
A massive adoption signal in France
Until now, investing in crypto in France required using specialized platforms (Binance, Coinbase, or an AMF-registered provider). With BNP Paribas, crypto enters the traditional banking distribution channel. For millions of French clients, accessing Bitcoin becomes as simple as buying a stock.
The risk not to overlook: ETNs carry counterparty risk. If the issuer goes bankrupt, the investor can lose everything — unlike directly holding cryptocurrencies in a personal wallet.
First Bitcoin-backed mortgage in the United States
Coinbase and mortgage lender Better have launched the first Fannie Mae-compliant home loan backed by cryptocurrency. This is the first time the US federal agency — which guarantees the majority of the country’s mortgages — accepts Bitcoin as collateral.
How the mechanism works
The structure relies on two separate loans:
- A standard mortgage taken out through Better, compliant with Fannie Mae standards
- A second loan, backed by Bitcoin or USDC, that funds the down payment
The borrower transfers crypto assets to a custody wallet managed by Better and retains ownership of their BTC. The interest rate runs 0.5 to 1.5 percentage points higher than a standard 30-year mortgage, depending on the borrower’s profile.
Collateral ratios
For Bitcoin, the collateral deposited must represent at least 250% of the funded down payment. For USDC, the ratio drops to 125%, as the stablecoin is less volatile.
Crucially: no margin calls. If Bitcoin’s price drops, the loan terms remain unchanged and no additional collateral is required. Liquidation only occurs after 60 days of missed payments, just like a conventional mortgage.
The tax advantage
For US Bitcoin holders, selling BTC to fund a home down payment triggers a taxable event (capital gains). This product lets holders keep their crypto and avoid taxes, while using it as a wealth-building tool. It’s a paradigm shift: Bitcoin becomes a productive asset, not just a speculative one.
Polymarket: the NYSE bets $2 billion on prediction markets
Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange, has finalized an additional $600 million investment in Polymarket. In total, ICE will have injected nearly $2 billion into the prediction market platform — $1 billion in October 2025 and $600 million in March 2026.
Why the NYSE’s owner cares about betting
ICE’s thesis isn’t about Polymarket’s valuation itself, but about the data generated by its users. Prediction markets produce real-time sentiment indicators on geopolitical, economic, and political topics. ICE plans to distribute this data globally, creating a new layer of financial intelligence.
Polymarket hit nearly $10 billion in monthly volume in March 2026. Its competitor Kalshi, recently valued at $22 billion, generates approximately $1.5 billion in annual revenue.
California legislates against insider trading
This growth hasn’t been without controversy. California Governor Gavin Newsom signed an executive order banning state officials and public employees from using privileged information to bet on prediction markets.
The move followed concrete cases: six suspicious accounts allegedly pocketed $1.2 million betting on a US military strike against Iran, funded just days before the operation. Newsom stated: “Public service shouldn’t be a get-rich-quick scheme.”
The ban extends to spouses, family members, and former business partners of the officials concerned.
What these announcements mean for investors
These three stories point to a common trend: crypto’s integration into traditional financial systems.
- In France, BNP Paribas makes Bitcoin accessible through a simple brokerage account, removing the technical barrier
- In the United States, Bitcoin becomes a wealth asset usable as mortgage collateral through Fannie Mae
- On the markets, data from crypto prediction platforms is valued at billions of dollars by the world’s largest exchanges
For crypto investors, the lesson is clear: institutions are no longer asking whether to integrate crypto, but how. The open question remains regulation — and David Sacks’ departure as Trump’s “crypto czar” after his 130-day term reminds us that the US legislative framework remains unfinished.
Glossary

- Bitcoin (BTC): The first and largest decentralized cryptocurrency, created in 2009 by Satoshi Nakamoto. Used as a store of value and medium of exchange.
- Ethereum (ETH): The second-largest cryptocurrency by market cap. A programmable blockchain enabling smart contracts and decentralized applications.
- Collateral: An asset pledged as security for a loan. If the borrower defaults, the lender can seize the collateral to recover losses.
- Prediction market: A platform where users bet on the outcome of future events (elections, geopolitics, economics). Prices reflect the market’s perceived probability.

Frequently Asked Questions
What is a Bitcoin ETN and how does it differ from an ETF?
An ETN (Exchange Traded Note) is an exchange-listed debt security that tracks Bitcoin’s performance. Unlike an ETF, which physically holds the underlying asset, an ETN is a bond issued by a financial institution. The investor is therefore exposed to the issuer’s counterparty risk in addition to Bitcoin’s volatility.
Do BNP Paribas clients actually own Bitcoin?
No. By purchasing a Bitcoin ETN through BNP Paribas, the client acquires a financial instrument that tracks Bitcoin’s price, but does not directly hold the cryptocurrency. There is no wallet, no private keys. It is an indirect investment, regulated under the MiFID II framework.
How does a Bitcoin-backed mortgage work?
The borrower deposits Bitcoin (minimum 250% of the loan value) or USDC (125%) as collateral with Better. This deposit funds the down payment for a standard Fannie Mae-compliant mortgage. The advantage: no need to sell crypto, so no capital gains tax is triggered.
What happens if Bitcoin's price crashes during the mortgage?
Nothing changes for the borrower. There are no margin calls and no requirement to deposit additional collateral. The loan terms remain the same as long as monthly payments are made. Liquidation only occurs after 60 days of missed payments.
What is Polymarket and why is the NYSE investing in it?
Polymarket is a prediction market platform where users bet on the outcome of events (geopolitics, elections, economics). ICE, the NYSE’s parent company, has invested nearly $2 billion because the sentiment data generated by these markets represents a valuable new source of financial intelligence.
Are these crypto products available to European investors?
The BNP Paribas ETNs will be available in France from March 30, 2026. However, the Bitcoin mortgage (Coinbase/Better/Fannie Mae) and Polymarket are not accessible to European residents — these products are currently US-only.
