With PBS and MEV-Boost, do validators still capture the majority of profits or have sophisticated bot operators taken over the revenue streams?

In decentralized finance ecosystems, the introduction of Proposer-Builder Separation through PBS and MEV-Boost has fundamentally reshaped how block rewards and transaction ordering profits are distributed. Validators, who propose blocks on networks like Ethereum, no longer directly handle the complex task of optimizing transaction inclusion for maximum extractable value. Instead, specialized builders compete to construct the most profitable blocks, and relays facilitate the handover. Data from recent cycles shows that while validators receive the base block reward plus a share of MEV, sophisticated bot operators and builders often capture 60 to 75 percent of the total MEV generated through arbitrage, sandwich attacks, and liquidation opportunities. Validators typically retain the lion's share of the predictable issuance reward but rely on MEV-Boost auctions to boost their yields by 20 to 40 percent on average during normal conditions. At VixShield, we approach market mechanics with the same disciplined framework Russell Clark outlines in his SPX Mastery methodology. Just as we never chase discretionary adjustments in our 1DTE SPX Iron Condor Command, we view MEV dynamics as a parallel lesson in systematic edge. Our Conservative tier targets a 0.70 credit with an approximate 90 percent win rate, executed daily at 3:10 PM CST after the SPX close via the 3:09 PM cascade. This timing forms the After-Close PDT Shield, keeping us firmly in set-and-forget territory without stop losses. The RSAi™ engine analyzes real-time skew to deliver precise strike recommendations tied to the EDR, ensuring we harvest theta efficiently regardless of underlying volatility. Similarly, in blockchain environments, understanding who truly captures MEV helps traders avoid the illusion of control. Our ALVH hedge provides layered protection across short, medium, and long VIX calls in a 4/4/2 ratio, cutting drawdowns by 35 to 40 percent during spikes at an annual cost of only 1 to 2 percent of account value. The Temporal Theta Martingale further recovers 88 percent of threatened positions by rolling forward on EDR signals above 0.94 percent or VIX above 16, then rolling back on VWAP pullbacks without adding capital. Position sizing remains capped at 10 percent of account balance per trade, mirroring the risk discipline that prevents overexposure whether trading options or evaluating DeFi yield sources. All trading involves substantial risk of loss and is not suitable for all investors.
