Numeraire, The Cryptocurrency Powering The World Hedge Fund

In 2017, Numerai released a new API that allows people around the world to submit predictions from machine learning models to power our hedge fund.

In 2018, we are focussing on our cryptocurrency, Numeraire (NMR). We are going to make NMR more valuable to use, and we are going to dramatically grow the number of data scientists who use it.

Numeraire Usage

Every user on Numerai has an opportunity to stake NMR tokens on their predictions as a way to express the confidence they have in their model. If their predictions are good, they earn money and their NMR is returned. If their predictions are poor, their NMR is destroyed.

The most important usage metric for us is whether the biggest earners of NMR are also the biggest stakers i.e. the whales are the users. And this is exactly what is happening on Numerai.

If you go to the leaderboard on Numerai and sort by the career earnings of NMR, you can see that out of the top 15 NMR earners, 7 are currently staking NMR. So nearly half of the participants that have the largest amounts of NMR are staking it every week. I don’t know of a single cryptocurrency project where the token is used so widely and frequently by its largest holders.

On Numerai, the whales are the users (blue means currently staking NMR)

A big reason for this usage is that Numerai did not sell its token in an ICO to speculators with no intention of using it. Instead we gave it away proportionally to the best data scientists on Numerai — the people who were most likely to use it. And on the day of the launch, NMR was not only usable but used immediately by its recipients. Some of our data scientists have staked NMR every single week since launch (see for example,

Numeraire Effectiveness

The reason we ask data scientists to risk NMR by staking it on their models is so that only the good models get staked. And this is happening too.

When Numerai users submit predictions, they also submit predictions on a test set. Users do not get feedback on their performance on this test set nor do they even know what our data represents; this ensures that backtests on this test set are rigorous.

We analyzed the Sharpe ratio of the unstaked models vs the staked models based on the backtest of the test set. Here is the performance:

Sharpe ratio of unstaked models: 1.66

Sharpe ratio of models staked with NMR: 2.09

Our backtests have many parameters such as how we combine the models together, how we optimize the portfolio, and how we estimate trading costs. With the above Sharpe ratios, we assume that we equal weight the models, assume no trading costs, and don’t do any optimization.

This difference in Sharpe means that staked models earn significantly more returns with lower volatility in the backtest. For example, for the same 10% of volatility, the staked models would earn 20.9% whereas the unstaked models would earn just 16.6% — a big difference for a hedge fund.

NMR is a huge success story for a utility token. It is widely held and being used by its holders. NMR has led to the exact intended outcome of the white paper we published one year ago. It engineers a precise behavior and improves the performance of models on Numerai.

A 5x Increase

Because staking NMR is such a powerful signal, we want to put an even greater focus on it this year.

We have just increased the staking payout to 2000 NMR + 6000 USD. At the current price of NMR on secondary markets, this change is a 500% increase in payouts in the staking tournament.

Starting today, the only way to earn NMR is by staking NMR. This means staking NMR becomes even more valuable, and more NMR will now go to the users who are holding it and staking it.

The total earnings available on Numerai is over $140,000 per month making it the most well-paid data science tournament on the planet.
