You take a side on a single political outcome. The position becomes a tail running into your account core.
A second outcome joins the same core. Coattail reads the pull between the two rather than treating them as strangers.
Separate collateral blocks merge into one requirement. Offsetting legs release capital instead of freezing it.
Rates settle continuously along every link, so the price of one outcome cannot drift away from the outcomes it moves with.
When the account runs short, the weakest link is cut first. The rest of the network stays connected and alive.
