A trio of ticket holders shared Saturday's totescoop6 after selecting Pricewise pick Bayan to win the final leg at Ascot.
Each of the three collected £103,316 and they will now have the chance to pocket an extra £204,240 in the bonus race next weekend.
Early indications suggest the three winners are all small staking internet clients, one of whom invested just £4 via Betfair.
totepool spokesman Andrew Griffiths said: "What a Christmas it's going to be for the three winners with £100,000 in the bank. We're absolutely delighted for them and we hope that they enjoy their win."
A total of £292,702 was bet into this afternoon's pools and there were 4,324 winners of the place fund, which returned £11.80.
