The split

The split is side A's share of the duel. It is the large number on every duel, 54% against 46%, and it decides the rounds.

How it is read

The split comes from the two ETH pools. If P is A's price in ETH divided by B's price in ETH, side A's share is:

share of A = P / (1 + P)

At launch both supplies are equal, so the split also matches A’s share of the combined market caps. P = 1 and the split starts at 50% / 50%. Later burns can make the supplies unequal; the split continues to compare prices per token.

What moves it

Every trade in ETH:

  • buying A with ETH raises A's price, and the split moves toward A;
  • selling A lowers it, and the split moves toward B;
  • switching from B to A moves it toward A from both ends: B is sold and A bought.

A switch can go through the A/B pool, which changes no ETH price by itself. If the subsequent realignment runs, its ETH trades can move the split. If it is skipped or moves no ETH price, neither the split nor the round’s average changes. The A/B price never counts directly.

Market caps and the split

For equal supplies and fixed liquidity, a price ratio of 4:1 (an 80% / 20% split) corresponds to a 2:1 ratio of virtual plus real ETH. It does not imply twice as much real deposited ETH; after burns, the market-cap ratio can also differ from the price ratio. Move the sliders:

Try it: ETH spent buying each side

Market cap of A13.2 ETH
Market cap of B4.31 ETH
75.3% AB 24.7%

Each side alone, with the default 1.2% fee: price grows with the square of the sum of virtual ETH and deposited ETH, so doubling a deposit does not generally quadruple market cap. Realignment can also move the other side (see Realignment).

The leader has an edge, not a lock

The A/B pool couples the sides when profitable realignment runs. A purchase on one side can then also raise the other side’s ETH price. The strength of that coupling depends on the cross-pool allocation, pool balances and whether the loop can complete; a price lead is not a guaranteed round win.

The split you see and the round's average

The large split is live: it follows the two ETH prices. The round’s average instead integrates their log price ratio over time, then converts it back into a share, shown as “Leading this round… on average”. See Rounds.
