Polkadot's treasury, holding nearly $245 million in assets, is predicted to last for two more years at its current spending rate. The treasury's complexity is increasing, with spending on direct allocations, bounties, and future collectives. The treasury holds $188 million in liquid assets, primarily in Polkadot's native token (DOT), along with Tether (USDT) and USD Coin (USDC). The first half of the year saw a significant increase in spending, with $87 million spent in total and over 40% of that on advertising and events. However, concerns about the treasury's usage are growing, with balances falling since mid-last year due to a decrease in network fees.
